Aircraft Accident/Incident Report
Howell, Michigan 48844
Thursday, September 25, 1997 11:47 EDT
NTSB Narrative Summary Released at Completion of Accident
The instructor pilot had shut down and secured the airplane's left engine as part of a final checkout flight he was giving to a student, prior to her taking her practical test for a multi-engine rating. During the restart attempt, the propeller did not come out of feather, and the engine would not start. The instructor pilot had to manually extend the landing gear, because the hydraulic pump for the gear was on the left engine. They did not get the three green lights, indicating that the airplane's gear was down and locked. The pilot performed a fly-by during which he was informed that the gear appeared to be down. By the time the instructor pilot and student received this information, they were too far down the runway to land, so they executed a go-around. The instructor pilot then took control of the airplane and brought it in for landing. During the touchdown, the landing gear collapsed. Examination of the emergency landing gear extension system revealed that whenever flaps are selected during the hand pumping process, hydraulic pressure to the emergency landing gear system is interrupted, leaving the gear in an intermediate position. Hydraulic pressure is restored once flap extension/retraction is complete.
NTSB Probable Cause Narrative
the emergency landing gear extension system being impeded by flap extension. Factors contributing to this accident are the instructor pilot's intentional feathering of the airplane's left propeller, the instructor pilot's lack of familiarity with the airplane, and insufficient information provided in the pilot's operating handbook warning the operator that extending flaps during emergency gear extension will interrupt hydraulic pressure to the system.
