Flight Details
The flight was scheduled to review flight maneuvers prior to a student's practical test for a private pilot certificate. The airplane was configured with 25 degrees of flaps for a simulated short field takeoff. The flight instructor reported that the engine sounded smooth during the entire flight and the airplane appeared to accelerate normally, becoming airborne by the 2,000-foot runway marker.
After breaking ground, the student pilot, who had 66 hours of flight experience, established the airplane at the best angle of climb speed. However, the airplane's climb performance was degraded to the point that it was only climbing at a rate of 100 feet per minute. The flight instructor assumed the controls and initially managed to maneuver the airplane around rising terrain and obstructions at the departure end of the runway.
Engine Examination
Under the supervision of an FAA inspector, the engine was examined. It was started and operated through the normal flight parameters. No pre-existing engine deficiencies were noted, and the investigation did not reveal any evidence that the engine was not capable of operating and producing power prior to the accident.
