Background
The pilot in command was also a mechanic with inspection authority. He conducted a maintenance test flight on an aircraft that had a servo fuel injector previously identified as unairworthy. The flight was intended to test systems following maintenance.
Events During Flight
During the initial climb after takeoff, the pilot experienced a partial loss of engine power. He promptly contacted Air Traffic Control to report the problem and initiated maneuvers with the goal of returning to the departure airport.
Forced Landing
Despite his efforts, the pilot was unable to successfully return to the airport. The aircraft made a forced landing during which it struck trees, overhead electrical wires, and a private residence. The collision sequence occurred as the aircraft descended into the residential area.
Regulatory Context
Title 14 of the Code of Federal Regulations, Section 91.7(b), specifies that the pilot in command must ensure the aircraft is in a condition for safe flight. It further requires that the flight be discontinued if an unairworthy mechanical, electrical, or structural condition becomes apparent.
