Aircraft Accident/Incident Report

Lehighton, Pennsylvania 18235
Tuesady, April 22, 1997 13:45 EDT

NTSB Narrative Summary Released at Completion of Accident

The student pilot was undergoing a private pilot proficiency evaluation. During a go-around following a simulated forced landing, the flaps failed to retract. The student pilot gave the controls to the flight examiner and replaced the fuse for the flap actuating system. The fuse was installed with the flap handle in the fully retracted position, which resulted in the operation and inadvertent retraction of the flaps. The student pilot stated that the airplane then stalled, descended 60 to 100 feet, and landed hard in a field.

NTSB Probable Cause Narrative

replacement of the flap actuating system fuse by the pilot-in-command with the flap actuating handle in the fully retracted position. This resulted in the retraction of the flaps, an inadvertent stall/mush, and the subsequent in-flight collision with terrain.
