Incident Overview
Two multiengine-rated pilots, both holding Certified Flight Instructor (CFI) certificates, were conducting a training flight. The second pilot was receiving instruction in preparation for his multiengine instructor certificate.
Sequence of Events
During the takeoff roll, the left engine would not develop full power. After becoming airborne, the pilots entered the closed traffic pattern. While on the downwind leg, the airplane would not sustain flight. The instructor pilot sensed that the left engine had lost power but did not feather the propeller. He relied on the manifold pressure gauge to assess engine condition.
Forced Landing and Impact
The instructor pilot executed a forced landing and attempted to return to the departure runway. The airplane impacted the terrain in a 45-degree left bank, 15 degrees nose low, short of the intended landing point. The pilot did not attempt to flare the airplane before impact. A post-crash fire ensued, destroying the airplane.
Investigation Findings
An investigation into the incident found no cause for the power loss to the left engine.
