Atlas Air Flight 3591 was a scheduled domestic cargo flight under the Amazon Air banner between Miami International Airport and George Bush Intercontinental Airport in Houston. On February 23, 2019, the Boeing 767-375ER(BCF) used for this flight crashed into Trinity Bay during approach into Houston, killing the two crew members and a single passenger on board. The accident occurred near Anahuac, Texas, east of Houston, shortly before 12:45 CST (18:45 UTC). [1] [2] [3] This was the first fatal crash of a Boeing 767 freighter. [4]
Investigators attributed the accident to pilot error, finding that the first officer experienced spatial disorientation and inadvertently placed the aircraft in an unrecoverable dive, while the captain failed to adequately monitor the first officer's actions and the flight path of the aircraft. Flight crew training issues at Atlas Air and across the U.S. commercial aviation industry were also implicated.
The Boeing 767-375ER(BCF) (MSN 25865/430) aircraft was registered N1217A and was nearly 27 years old at the time of the accident, having been built in 1992. It was originally ordered by Canadian Airlines, but first placed into service by China Southern Airlines through GPA, an aircraft leasing company. [5] In 1997, it was transferred to LAN Airlines and flew until 2014 before being returned to lessor CIT and then being stored in January 2016. It was converted into a freighter in April 2017, and placed into service for Amazon Prime Air by Atlas Air. [6] In August 2018, Amazon named two aircraft in its fleet, including N1217A as CustomAir Obsession. The name, painted on the aircraft just aft of the cockpit windows, [7] was a near homonym of "customer obsession," an Amazon leadership principle. [8] The aircraft had accumulated more than 91,000 hours over 23,300 flights [9] [10] [11] and was powered by two GE CF6-80 turbofan engines. [11] : 8–9 [12]
There were three people on board the aircraft: [13] Captain Ricky Blakely of Indiana (60), first officer Conrad Jules Aska of Cedar Grove, Antigua (44), and Mesa Airlines captain Sean Archuleta of Houston (36; a jumpseater aboard the flight), who was in his final week of employment at Mesa Airlines and was traveling to work before beginning new-hire pilot training with United Airlines scheduled for the following week. [14]
Blakely joined Atlas Air in 2015 and became a Boeing 767 captain in 2018. Before being hired by Atlas Air, Blakely had previously been an Embraer ERJ-145 captain for ExpressJet. He had also been a Beechcraft 1900 first officer for CommutAir, and a flight instructor for FlightSafety International. [11] : 5 Blakely logged a total of 11,172 flight hours, including 1,252 hours on the Boeing 767. [11] : 3–4
Aska joined Atlas Air on July 3, 2017, and received his type rating on the Boeing 767 two months later. He had logged 5,073 flight hours, with 520 of them on the 767. Aska had previously been an Embraer E175 first officer with Mesa Airlines (and served with five other airlines prior to that) and also had experience on Embraer's EMB 120 Brasilia and ERJ aircraft families. [11] : 5, 7 [15]
Both pilots had previous experience in landing at George Bush Intercontinental Airport [15] and they flew together on the previous day, operating a night-time flight from California to Miami. [15]
Atlas Air 3591 departed Miami at 10:33 CST (11:33 EST), with Aska as the pilot flying and Blakely monitoring the controls. At 12:36, Aska transferred control of the aircraft to Blakely, telling him that the electronic flight instrument (EFI) switch on his side had malfunctioned. This issue was resolved a minute later, with the following being recorded on the cockpit voice recorder (CVR):
Flight 3591 was on approach towards Houston when it flew through the forward edge of a cold front, which produced an area of instrument meteorological conditions (IMC) with clouds and turbulence, with cloud tops varying from approximately 19,500 feet (5,900 m) to 27,300 feet (8,300 m) of altitude and cloud bases varying from 2,000 feet (610 m) to 3,000 feet (910 m) above ground level. The pilot of another nearby airliner reported IMC, and a video taken by a ground witness showed a shelf cloud passing over the area at the time. [11] : 14–15
First officer Aska then requested radar vectors to the west side of the airport to avoid the inclement weather. The controller accepted though advised the crew to expedite their descent to 3,000 feet (910 m) and said, "I'm gunna get ya west of this weather and northbound for a base leg." Blakely then transferred control of the aircraft back to Aska:
The flight crew then started to configure the aircraft for landing and set up the flight management system (FMS). At 12:38:02.2 CST, Aska called out "flaps one”, and the slats were extended. 29 seconds later, the aircraft's go-around mode was activated. At 12:38:40.3, the following was heard on the CVR:
The accident aircraft made a sharp turn south before going into a rapid descent. Witnesses to the crash described the plane entering a nosedive; some also recalled hearing "what sounded like lightning" before the Boeing 767 hit the ground. [16] [17]
At 12:36 CST (18:36 UTC), radar and radio contact was lost. There was no distress call. [18] At 12:39:03.9 CST (18:39:03.9 UTC), the time the CVR recording ended, Flight 3591 crashed into the north end of Trinity Bay at Jack's Pocket. [2] The area of water is within Chambers County, Texas, and is in proximity to Anahuac. [19]
The Federal Aviation Administration (FAA) issued an alert after radar and radio contact was lost around 30 miles (50 km) southeast of its destination. [20] Air traffic controllers tried at least twice to contact the flight, with no response. Controllers asked pilots aboard two nearby flights if they saw a crash site, both of whom said they did not; the crash site was located after ground witnesses called local police to report having seen the aircraft dive into the bay. The United States Coast Guard dispatched a helicopter and several boats to search for survivors; other agencies responded as well. The crash site was mostly mud marsh, with water varying in depth from zero to five feet (1.5 m) deep, and airboats were needed to access the area. Searchers found human remains and many small fragments of the aircraft and its cargo; the largest recovered piece of the aircraft was 50 ft (15 m) in length. The local sheriff described the scene as "total devastation" and surmised that the crash had not been survivable. [21] [22]
On February 24, Atlas Air confirmed that all three people on board died. [3] [23] The victims were first identified on social media by friends and family. By February 26, the bodies of all three had been recovered, and by March 4, all had been positively identified. [24]
Investigators from the FAA, Federal Bureau of Investigation (FBI), and National Transportation Safety Board (NTSB) were dispatched to the accident site with the NTSB leading the accident investigation. [25] A dive team from the Texas Department of Public Safety (DPS) was tasked with locating the aircraft's flight recorders and dive teams from the Houston and Baytown police departments were also on-scene assisting in the search. [26] The CVR and flight data recorder (FDR) were located and transported to an NTSB lab for analysis. [27] [28] It was thought that crews would likely remain at the accident site for weeks for recovery. [29]
It was noted that storm cells were nearby at the time of the accident, but this is not unusual for Bush Intercontinental. [30] CCTV cameras at the Chambers County jail show the airplane in a steep, nose-low descent just prior to impact. [31] [32] [33]
The FAA, Boeing, Atlas Air, National Air Traffic Controllers Association (NATCA), International Brotherhood of Teamsters (the pilots' labor union), Air Line Pilots Association, [34] and engine maker General Electric assisted or offered their assistance to the NTSB inquiry. [35]
After listening to the cockpit voice recorder, the NTSB stated that "Crew communications consistent with a loss of control of the aircraft began approximately 18 seconds prior to the end of the recording." [36] On March 12, the NTSB stated that the airplane "pitched nose down over the next 18 seconds to about 49° in response to column input." Later that same day, the statement was changed to "...in response to nose-down elevator deflection." [10] [37]
On December 19, 2019, the NTSB released a public docket containing over 3,000 pages of factual information it had collected during the investigation, with a final report to follow at an unspecified later date. The docket contains information on "operations, survival factors, human performance, air traffic control, aircraft performance, and includes the cockpit voice recorder transcript, sound spectrum study, and the flight data recorder information." [38]
On June 11, 2020, the NTSB announced that the next board meeting would determine the cause of the accident; [39] the NTSB determined during a public board meeting held on July 14, that the flight crashed because of the first officer's inappropriate response to an inadvertent activation of the airplane's go-around mode, resulting in his spatial disorientation that led him to place the airplane in a steep descent from which the crew did not recover. [40] The NTSB released an animation of the mishap sequence of events from the selection of Go-Around thrust to the fatal crash 31 seconds later. [41]
On August 6, 2020, the NTSB posted the final accident report to their website, which stated:
The NTSB determines that the probable cause of this accident was the inappropriate response by the first officer as the pilot flying to an inadvertent activation of the go-around mode, which led to his spatial disorientation and nose-down control inputs that placed the airplane in a steep descent from which the crew did not recover. Contributing to the accident was the captain's failure to adequately monitor the airplane's flightpath and assume positive control of the airplane to effectively intervene. Also contributing were systemic deficiencies in the aviation industry's selection and performance measurement practices, which failed to address the first officer's aptitude-related deficiencies and maladaptive stress response. Also contributing to the accident was the Federal Aviation Administration's failure to implement the pilot records database in a sufficiently robust and timely manner. [11]
The NTSB found that the descent had proceeded normally until the go-around mode was actuated and the aircraft's autopilot and autothrottle increased engine thrust and nose-up pitch as designed. Neither pilot verbally acknowledged that go-around mode had been actuated nor took any apparent action to deactivate it. Moments later, the first officer made nose-down flight control inputs for stall recovery, but the aircraft's stall warning systems had not actuated and FDR data was inconsistent with an aircraft in a stalled condition. [11] : 2 The NTSB concluded that the first officer most likely struck the go-around switch accidentally with his left wrist or his wristwatch while manipulating the nearby speedbrake lever and that neither pilot realized that the aircraft's automated flight mode had been changed. [11] : ix During a stall, established procedures called for the pilot flying (PF) to "Hold the control column firmly", "Disengage the autopilot and autothrottle", and "Smoothly apply nose-down elevator control to reduce the AOA (angle-of-attack) until stick shaker or buffet stops". The procedures further state that the pilot monitoring (in this case the captain) should monitor and call out changes in altitude / airspeed, call out any trend toward terrain, and verify that all required actions are being completed. [11] : vii, 27 While the first officer's flight control inputs were aggressive enough to override the autopilot, [11] : 20 investigators concluded that the captain was distracted performing other tasks and had failed to monitor the aircraft's performance. [11] : 42–43
The NTSB concluded that the aircraft was likely flying in IMC without the ground visible when the go-around mode was actuated, [11] : 41 and the first officer most likely experienced a pitch-up or head-up somatogravic illusion, the false sensation that one is tilting backwards during unexpected forward acceleration in the absence of visible landmarks. Pilots with limited instrument flight proficiency have a well-documented tendency to disregard flight instruments and act instinctively in reaction to this illusion. [11] : ix, 40–41 Investigators concluded that the pilots were unable to see the ground until the aircraft exited the clouds approximately 3,000 feet (910 m) above the bay, at which point safe recovery from the steep descent would have been impossible. [11] : 44–45
The NTSB was unable to determine why the first officer cycled the EFI switch prior to the accident; however, cycling the EFI switch in the 767 is generally done to solve intermittent display blanking and does not change the source of the data shown on the display, and the NTSB concluded that "whatever EFIS display anomaly the FO [first officer] experienced was resolved to both crewmembers' satisfaction (by the FO's cycling of the EFI switch) before the events related to the accident sequence occurred." [11] : 37
The NTSB noted that both pilots had difficulties in their training. Blakely experienced difficulties during training for his type rating on the 767. On October 31, 2015, he was declared unfit for a checkride due to unsatisfactory remarks on his training which included the following: [11] : 4
Blakely underwent remedial training the next day on November 1, this time with satisfactory results. The day after, he had his 767 checkride, and received his type rating on the aircraft two days later. [11] [15] Despite Blakely's improvements, Atlas Air placed him in the pilot proficiency watch program (PWP) due to his training issues. [11]
First officer Aska had also experienced training difficulties with Atlas Air, more so than Blakely. He had also recorded training failures with previous employers. Another Atlas Air 767 captain who had flown with Aska described him as a "nice guy" and "definitely in the top half of the people I've flown with," though he did not state any issues regarding training. [42] Aska's first issues were reported in July 2017, the same month he joined Atlas Air, when he was declined an oral exam for his type rating on the 767 as he needed remediation training. Following the training, he passed the oral exam. Aska then went through five fixed-base (non-moving) flight simulator sessions, experiencing difficulties with normal procedures, and underwent more remediation training. In August, following two full-flight simulator training sessions, Aska's simulator partner complained that he was being "held back." Atlas Air ultimately had to restart full-flight simulator training for Aska because no other pilots remained in his training class to partner with him. [11] : 5–6
Aska's first checkride on the aircraft ended in failure due to poor crew resource management (CRM) and improper aircraft control. His examiner described him as stressed and lacking situational awareness. [11] : 6 Aska underwent remedial training on September 25 and the next day, he reattempted his checkride successfully, receiving his type rating on the aircraft. [11]
Investigators concluded that Aska had deliberately concealed his spotty training record when he interviewed with Atlas Air, taking advantage of shortcomings in the FAA pilot records database, which was criticized by the NTSB. A 2010 amendment to the Pilot Record Improvement Act (PRIA) passed after the 2009 crash of Colgan Air Flight 3407 required the FAA to record training failures in the database; however, this provision had not been fully implemented due to privacy concerns and industry opposition, particularly from business aviation operators who objected to the program's stringent record-keeping requirements. Atlas Air was also criticized for its reliance on agents rather than flight operations specialists to check the training backgrounds of pilots it hired. [43]
The NTSB recommended that pilots of the 767 and the similar Boeing 757 be trained to recognize and recover from inadvertent go-around mode actuation, but also concluded that available data suggested that such an actuation was a "rare and typically benign event." [11] : viii
The crash was featured in season 23 of the Canadian documentary series Mayday , titled "Delivery to Disaster". [44]
Atlas Air, Inc. is a major American cargo airline, passenger charter airline, and aircraft lessor based in White Plains, New York. It is a wholly owned subsidiary of Atlas Air Worldwide Holdings. Atlas Air is the world's largest operator of the Boeing 747, with 54 of the type. In 2021, the airline had 4,056 employees and operated to more than 300 global destinations.
Aircraft upset is an unacceptable condition, in aircraft operations, in which the aircraft flight attitude or airspeed is outside the normally intended limits. This may result in the loss of control (LOC) of the aircraft, and sometimes the total loss of the aircraft itself. Loss of control may be due to excessive altitude for the airplane's weight, turbulent weather, pilot disorientation, or a system failure.
During the 1990s, a series of issues affecting the rudder of Boeing 737 passenger aircraft resulted in multiple incidents. In two separate accidents, pilots lost control of their aircraft due to a sudden and unexpected rudder movement, and the resulting crashes killed everyone on board, 157 people in total. Similar rudder issues led to a temporary loss of control on at least one other Boeing 737 flight before the cause of the problem was ultimately identified.
EgyptAir Flight 990 (MSR990) was a scheduled flight from Los Angeles International Airport to Cairo International Airport, with a stop at John F. Kennedy International Airport, New York City. On October 31, 1999, the Boeing 767-300ER operating the route crashed into the Atlantic Ocean about 60 miles (100 km) south of Nantucket Island, Massachusetts, killing all 217 passengers and crew on board, making it the deadliest aviation disaster for EgyptAir, and also the second-deadliest aviation accident involving a Boeing 767 aircraft, behind Lauda Air Flight 004.
Continental Airlines Flight 1404 was a Continental Airlines domestic flight from Denver International Airport in Denver, Colorado, to George Bush Intercontinental Airport in Houston, Texas. On the evening of December 20, 2008, the flight crashed while taking off from Denver, resulting in two critical injuries, 36 noncritical injuries, and a hull loss of the Boeing 737-524 aircraft.
Colgan Air Flight 3407 was a scheduled passenger flight from Newark, New Jersey, US to Buffalo, New York, US on February 12, 2009. Colgan Air staffed and maintained the aircraft used on the flight that was scheduled, marketed, and sold by Continental Airlines under its Continental Connection brand. The aircraft, a Bombardier Q400, entered an aerodynamic stall from which it did not recover and crashed into a house at 6038 Long Street in Clarence Center, New York at 10:17 pm EST, killing all 49 passengers and crew on board, as well as one person inside the house.
FedEx Express Flight 80 was a scheduled cargo flight from Guangzhou Baiyun International Airport in China, to Narita International Airport in Narita, Chiba Prefecture, Japan. On March 23, 2009, the McDonnell Douglas MD-11F (N526FE) operating the flight crashed at 6:48 am JST, while attempting a landing on Runway 34L in gusty wind conditions. The aircraft became destabilized at flare and touchdown resulting in an unrecovered "bounced" landing with structural failure of the landing gear and airframe following pilot error due to poor training for bounced landings. The plane came to rest off the runway, inverted, and burning fiercely. The captain and first officer, the jet's only occupants, were both killed.
USAir Flight 427 was a scheduled flight from Chicago's O'Hare International Airport to Palm Beach International Airport, Florida, with a stopover at Pittsburgh International Airport. On Thursday, September 8, 1994, the Boeing 737 flying this route crashed in Hopewell Township, Pennsylvania while approaching Runway 28R at Pittsburgh, which was USAir's largest hub at the time.
In aeronautics, loss of control (LOC) is the unintended departure of an aircraft from controlled flight and is a significant factor in several aviation accidents worldwide. In 2015 it was the leading cause of general aviation accidents. Loss of control may be the result of mechanical failure, external disturbances, aircraft upset conditions, or inappropriate crew actions or responses.
National Airlines Flight 102 (N8102/NCR102) was a cargo flight operated by National Airlines between Camp Shorabak in Afghanistan and Al Maktoum Airport in Dubai, with a refueling stop at Bagram Airfield, Afghanistan. On 29 April 2013, the Boeing 747-400 operating the flight crashed within the perimeter of the Bagram airfield moments after taking off, killing all seven people on board.
Southwest Airlines Flight 345 was a scheduled flight from Nashville International Airport, Tennessee to New York City's LaGuardia Airport. On July 22, 2013, the Boeing 737 operating the route suffered a front landing-gear collapse while landing at LaGuardia Airport, injuring 9 people on board. The aircraft, which was worth an estimated $15.5 million at the time, was written off and scrapped as a result of the accident.
UPS Airlines Flight 1354 (5X1354/UPS1354) was a scheduled cargo flight from Louisville, Kentucky, to Birmingham, Alabama. On August 14, 2013, the Airbus A300 flying the route crashed and burst into flames short of the runway on approach to Birmingham–Shuttlesworth International Airport. Both pilots were pronounced dead at the scene of the crash. They were the only people aboard the aircraft. It was the second fatal air crash for UPS Airlines.
United Airlines Flight 2885 was a scheduled cargo flight from Cleveland to Los Angeles, with stopover in Detroit. On January 11, 1983, a DC-8 operating as Flight 2885 crashed after take-off from Detroit, killing all three crew members. The National Transportation Safety Board (NTSB) investigation determined that the cause for the crash was pilot error. A radioactive package was found on board, but no radioactive material was spilled.
American Airlines Flight 383 was a scheduled passenger flight from O'Hare International Airport in Chicago, Illinois to Miami International Airport. On October 28, 2016, the Boeing 767-300ER operating the flight suffered an engine fire during takeoff. The crew aborted their takeoff, evacuating everyone on board, of whom 21 were injured. The plane was a write-off.
Amazon Air is a virtual cargo airline operating exclusively to transport Amazon packages. In 2017, it changed its name from Amazon Prime Air to Amazon Air to differentiate themselves from their Amazon Prime Air autonomous drone delivery service. However, the Prime Air logo remains on the aircraft. Until January 2021, the airline had relied on wet-leasing its aircraft from other operators, but going forward it is looking to directly own some aircraft. On the planes the airline owns, the airline will still rely on others for CMI leases.
Pan Am Flight 799 was an international cargo flight from Los Angeles International Airport to Cam Ranh Airport in South Vietnam that crashed on December 26, 1968, near Anchorage, Alaska. The aircraft involved was a Boeing 707-321C aircraft operated by Pan American World Airways. All three crew members died in the crash.
Airborne Express Flight 827 was a functional evaluation flight (FEF) of an Airborne Express Douglas DC-8-63F that had undergone a major modification. On December 22, 1996, during the test flight, the aircraft stalled and crashed, killing all six people on board. Accident investigators determined the cause of the accident was improper crew control inputs.
Transair Flight 810 was a Boeing 737-200 converted freighter aircraft, owned and operated by Rhoades Aviation under the Transair trade name, on a short cargo flight en route from Honolulu International Airport to Kahului Airport on the neighboring Hawaiian island of Maui on July 2, 2021. Immediately after an early morning takeoff, one of its two Pratt & Whitney JT8D turbofan engines faltered, and the first officer, who was flying the aircraft, reduced power to both engines. The two pilots—the only occupants of the aircraft—began executing the Engine Failure or Shutdown checklist, but became preoccupied with talking to air traffic control (ATC) and performing other flying tasks, never reaching the section of the checklist where the failing engine was to be positively identified and shut down. The captain assumed control but misidentified the failing engine, increased power to that engine, and did not increase power to the other, properly functioning engine. Convinced that neither engine was working properly and unable to maintain altitude with one engine faltering and the other idling, the pilots ditched off the coast of Oahu about 11 minutes into the flight.
On October 19, 2021, a corporate McDonnell Douglas MD-87, registered as N987AK, crashed and caught fire during take-off, 1,600 feet (500 m) from Houston Executive Airport. Those on board, 19 passengers and four crew members, were safely evacuated out of the aircraft. The aircraft was damaged beyond repair and was subsequently written-off.

Witnesses told emergency personnel that the twin-engine plane "went in nose first," leaving a debris field three-quarters of a mile long in Trinity Bay, Chambers County Sheriff Brian Hawthorne said. "It's probably a crash that nobody would survive," he said, referring to the scene as "total devastation."
