The 1977 Aviateca Convair 240 airplane crash was a scheduled Aviateca passenger flight that crashed near Guatemala City, Guatemala on April 27, 1977, killing all 28[citation needed] on board.[1]

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 exhaustion.[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, killing all 22 passengers and six crew on board.[citation needed]


The Government of Guatemala initiated a full investigation. The results of this investigation are as follows:[citation needed]

The aircraft had undergone maintenance shortly before the flight. In order to perform this maintenance, it was necessary to disconnect a high-pressure oil hose from the engine cylinders. The investigation found that it had not been correctly reattached, thus starving the engine of oil.[citation needed]
