Final moments

The aircraft, a Convair 240, took off from La Aurora International Airport (GUA/MGGT) in Guatemala City as scheduled. During the initial climb to cruise altitude, the number one engine suffered a failure due to oil loss.[ citation needed ] The crew was unable to feather the propeller, and was forced to attempt an emergency landing in rough terrain.[ citation needed ] The plane was destroyed in the attempt, but none of the 22 passengers and six crew on board were killed. [2]

Investigation

The government of Guatemala initiated a full investigation. It found that the aircraft had undergone maintenance shortly before the flight. In order to perform the maintenance, it was necessary to disconnect a high-pressure oil hose from the engine cylinders. The hose was not correctly reattached, thus starving the engine of oil. [2]

Convair 990 Coronado 1962–1987 American four-engined jet airliner

The Convair 990 Coronado is an American narrow-body four-engined jet airliner produced by the Convair division of General Dynamics, a stretched version of its earlier Convair 880 produced in response to a request from American Airlines. The 990 was lengthened by 10 ft (3.0 m), which increased the number of passengers from between 88 and 110 in the 880 to between 96 and 121 in the 990. This was still fewer passengers than the contemporary Boeing 707 or Douglas DC-8, although the 990 was 25–35 mph (40–56 km/h) faster than either in cruise.

Fuel starvation Problem affecting internal combustion engines

In an internal combustion engine, fuel starvation is the failure of the fuel system to supply sufficient fuel to allow the engine to run properly, for example due to blockage, vapor lock, contamination by water, malfunction of the fuel pump or incorrect operation, leading to loss of power or engine stoppage. There is still fuel in the tank(s), but it is unable to get to the engine(s) in sufficient quantity. By contrast, fuel exhaustion is an occurrence in which the vehicle in question becomes completely devoid of usable fuel, with results similar to those of fuel starvation.
