What happened
During the initial climb phase following departure from Pittsburgh International Airport, the aircraft's right engine ceased functioning. In response to the loss of power, the pilot-in-command executed a turn to the right with the intention of returning to the airfield. During this maneuver, the aircraft type experienced a stall, resulting in a crash into a residential neighborhood in Coraopolis, situated approximately three miles northeast of the airport. The impact caused a fire that destroyed the plane. Both members of the flight crew sustained serious injuries, though no individuals on the ground were harmed.
Findings
Investigations into the accident identified several mechanical and operational issues. The primary cause was determined to be an engine malfunction and subsequent stall during the climb, stemming from failures within the powerplant, fuel system, and carburetor. Specific contributing factors included:
- Improper installation of the carburetor and fuel system components, which led to leakage
- Failure to adhere to established flight procedures
- Incorrect management of the powerplant and its associated controls
- The decision to operate the aircraft despite being aware of equipment deficiencies
- An attempt to land away from the airport
- Failure to feather the right engine following the failure
- Executing a turn toward the non-functioning engine while attempting to return to the airport
