The 1977 Aviateca Convair 240 airplane crash was a scheduled Aviateca passenger flight that crashed near Guatemala City, Guatemala on April 27, 1977. All 28 people on board survived, but the aircraft was destroyed.[1][2]

Final moments[edit]

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]


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]
