On June 15, 1994, a Cessna 421C Golden Eagle III (registration N421AG) operated by Alexander A. Greco was involved in an aviation accident near Carlsbad-McClellan-Palomar, United States of America during takeoff. 2 people were killed. Investigators recorded the probable cause as: An undetermined loss of engine power combined with the pilot's failure to manage flaps and altitude led to the crash. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

An aircraft experienced a loss of engine power shortly after takeoff, resulting in an impact with terrain approximately 1.5 miles from the airfield.

What happened

Shortly after departing from the airport, the pilot communicated an emergency declaration, reporting that one of the engines had failed and requesting an immediate return to the airfield. During the attempt to return, the aircraft type descended into area characterized by thick brush and uneven terrain. The flight path ended when the plane collided with a significant dirt berm located roughly 1.5 miles northeast of the departure runway.

At the time of the impact, the landing gear had been pulled up, though the flaps remained extended at approximately 30 degrees. While the pilot and front passenger were not utilizing shoulder harnesses, the single surviving passenger reported no specific mechanical symptoms, noting only that the plane was unable to sustain its altitude.

Findings

Post-accident inspections of the engines showed no clear evidence of mechanical failure, and the fuel levels were found to be appropriate for the flight. Analysis of the combustion chambers suggested that the engines had been running under conditions of lean operation or mild detonation. The investigation identified that the loss of engine power occurred for reasons that could not be determined. Additionally, the crew's failure to retract the flaps and the inability to maintain necessary altitude were noted as contributing factors to the crash. The accident resulted in 2 fatalities and 1 injury.

Probable cause

An undetermined loss of engine power combined with the pilot's failure to manage flaps and altitude led to the crash.
