Probable cause
The failure of the wing flap control due to the improper type of fuse installed by unidentified persons. Factors relating to this accident were the flap motor partial failure due to corrosion and the total failure of the fuse due to the wrong type amperage.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot was practicing touch and go takeoffs and landings. The flaps were fully extended during the landing phase of the maneuver. During the second landing roll the pilot raised the flap handle and began the takeoff roll. When the airplane lifted off the pilot observed that the flaps remained fully extended and would not raise. The pilot was able to turn the airplane, but could not gain additional altitude without the stall warning horn activating. The pilot turned the airplane toward the airport but observed a powerline. The pilot was unable to climb over the powerline and banked the airplane. The airplane stalled during the banking turn. The post accident investigation revealed that the fuse had blown and was the wrong type of fuse. The flap motor terminals were corroded and the flap motor operated intermittently under all load conditions.
