Incident Overview
A multi-engine aircraft experienced a right engine failure shortly after departing from Pittsburgh-Intl Airport. During the initial climb, the pilot-in-command initiated a right turn with the intention of returning to the airport. The airplane subsequently stalled and crashed in flames in a residential area of Coraopolis, approximately three miles northeast of the airport.
Sequence of Events
The flight began normally, but shortly after takeoff, while climbing, the right engine failed. The pilot-in-command responded by turning the aircraft to the right and attempting to return to the departure airport. During this maneuver, the airplane stalled and descended uncontrollably, impacting the ground in a residential neighborhood. The collision resulted in a fire that consumed the wreckage.
Damage and Injuries
The aircraft was destroyed by the impact and subsequent fire. Both pilots sustained serious injuries. No injuries were reported among residents or others on the ground.
Probable Cause
The official investigation determined the probable cause to be an engine malfunction and a stall during the initial climb, attributed to a failure of the powerplant, fuel system, and carburetor. Contributing factors included improper installation of the fuel system and carburetor leading to leakage, failure to follow approved procedures, improper operation of the powerplant and controls, attempted operation with known deficiencies, a forced landing off airport terrain, failure to feather the right engine, and turning the aircraft toward the dead engine while attempting to return to the airport.
