On January 7, 1953, a Curtiss C-46F Commando operating as Associated Air Transport Trip 1-6-6A crashed into terrain approximately 8 miles west of Fish Haven, Idaho, killing all on board. [1] The plane had descended into an area of severe icing, causing ice to form on the wing, eventually crashing into the bottom of a ravine.
The flight departed Boeing Field at 12:50 AM MST, and proceeded en route to Cheyenne Airport. At 3:58 AM, the aircraft reported passing over Malad City, and estimated that it would reach Rock Springs at 4:45 AM. However, no further communications were received from the accident aircraft.
The aircraft was later found to have impacted several pine trees, slid down a ravine, and collided with the base of a hill on the other side of the ravine. [1]
The Curtiss C-46F Commando was registered as N1648M (MSN 22395). It had first flown in 1945, and at the time of the accident, the aircraft had 1941 airframe hours. [2]
The investigation determined that, while flying near the mountains in between Malad City and Bear Lake, the aircraft involuntarily descended into an area of ice and turbulence, to avoid storm clouds. Ice began to form on the wings of the aircraft, which led to a decrease in aircraft performance and, eventually, the aircraft impacting a hill at the bottom of a ravine. [2] [3]
The investigators determined that the aircraft experienced severe turbulence and wing icing, which led to the aircraft's crash. However, the investigators were unable to determine the reason for the aircraft's descent into severe turbulence and icing conditions. [3]
Capitol Air was a United States supplemental air carrier and, after 1978, a scheduled passenger air carrier based which was operational from 1946 to its bankruptcy filing on November 23, 1984. It was founded as Capitol Airways in 1946, and then renamed Capitol International Airways in 1967. Supplemental air carriers were also known as irregular air carriers or nonscheduled carriers. In 1981, the airline changed its name to Capitol Air and was operating scheduled domestic and international passenger flights that year.
This is a list of aviation-related events from 1953:
American Eagle Flight 4184, officially operating as Simmons Airlines Flight 4184, was a scheduled domestic passenger flight from Indianapolis, Indiana, to Chicago, Illinois, United States. On October 31, 1994, the ATR 72 performing this route flew into severe icing conditions, lost control and crashed into a field, killing all 68 people on board in the high-speed impact.
Zantop Air Transport was a United States airline incorporated in 7 July 1956 from the earlier Zantop Flying Service. It was a Part 45 carrier until 1962 when the Civil Aeronautics Board approved transfer of the operating certificate of Coastal Air Lines, making Zantop a supplemental air carrier. As a Part 45 carrier, Zantop was not a common carrier, it flew contract work for the Big Three automakers and for the Air Force Logair air freight service and with the US Navy, Quicktrans freight service up and down the Eastern Seaboard. As a supplemental, Zantop was able to hold itself out to the public as a general charter carrier. The original founders of Zantop Flying Services, the Zantop brothers, all sold their stock and resigned from the company in 1966. A name change was filed with the State of Michigan effective 29 December 1966 in the name of Universal Airlines, Inc.
Northwest Airlines Flight 1, registration NC17389, was a Lockheed Model 14 Super Electra aircraft which crashed in eastern Montana on Friday, January 13, 1939, approximately 0.5 miles (0.80 km) southwest of the Miles City Airport. All four on board were killed in the accident.
Slick Airways was one of the first scheduled cargo airlines in the United States, awarded a certificate for scheduled cargo service in the same proceeding that awarded a certificate to Flying Tiger Line.

On July 28, 1943, American Airlines Flight 63 was flown by a Douglas DC-3, named Flagship Ohio, routing Cleveland-Columbus-Dayton-Cincinnati-Louisville-Nashville-Memphis, that crashed on the Louisville-Nashville sector about 1.6 miles (2.6 km) west of Trammel, Kentucky. The aircraft descended from 200 feet (61 m) until it struck trees, then slid across an open field and stopped in an upright position. Of the 22 people on board, 20 died. The cause of the crash was loss of control due to severe turbulence and violent downdrafts.
Wien Consolidated Airlines Flight 55 was a scheduled domestic passenger flight in Alaska that crashed into Pedro Bay on December 2, 1968, killing all 39 on board. The Fairchild F-27B aircraft was operated by Wien Consolidated Airlines and was en route to Dillingham from Anchorage, with three intermediate stops. The NTSB investigation revealed that the aircraft suffered a structural failure after encountering "severe-to-extreme" air turbulence. The accident was the second-worst accident involving a Fairchild F-27 at the time, and currently the third-worst accident involving the aircraft.

On 27 July 1934, a Swissair Curtiss AT-32C Condor II passenger aircraft crashed near Tuttlingen, Germany, while flying through a thunderstorm. All 12 people on board were killed. It was the worst air crash in 1934 and Swissair's first aviation accident since its founding in 1931.
On the evening of April 1, 1993, a Swearingen Merlin III twin turboprop, carrying NASCAR champion Alan Kulwicki, crashed near Blountville, Tennessee, while on approach to the nearby Tri-Cities Regional Airport.

Aeroflot Flight 315 was a regularly scheduled passenger flight operated by Aeroflot from Vnukovo International Airport in Moscow to Lviv Airport in Lviv, Ukraine.

Siberian Light Aviation Flight 42 was a domestic Russian scheduled passenger flight from Kedrovy to Tomsk, both in Tomsk Oblast in Siberia. On 16 July 2021, the Antonov An-28 operating the flight suffered icing in the engines leading to a dual engine failure 10 minutes into the flight and crash landed in a remote area in the Vasyugan Swamp in the Bakcharsky District. The pilot suffered a broken leg requiring surgery, but all of the remaining passengers and crew escaped with only minor injuries. An investigation ultimately concluded that the pilots of the aircraft had not activated the anti-icing system, which led to an accumulation of ice, resulting in engine failure. Initially praised as a hero for his handling of the incident, the captain of the flight was ultimately criminally charged for violating safety protocols, leading to the crash.
The 1948 Bodaybo Li-2 crash was a fatal aviation accident involving a passenger aircraft operated by Aeroflot that occurred on April 24, 1948, when the plane lost control and crashed on the Vitim River near Bodaybo, resulting in the deaths of 28 people.
