Probable cause

An inoperative landing gear extension system due to failure of an electric motor and a misplaced emergency crank handle.

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.

Landing gear,normal retraction/extension assembly - inoperativeCause

Complete gear collapsedLanding - roll

Analysis

The pilot said that when he departed on a personal cross country trip, the landing gear failed to retract completely. He continued his trip. After arriving at his destination, he was unable to get a safe gear indication and was unable to lower the gear by emergency procedures. Low passes past the tower confirmed all three wheels were down, but the nose gear appeared not to be in position. A landing was made. During the roll-out, all three gear legs collapsed. A post- accident investigation revealed the gear motor was burned out and the landing gear emergency pump was inoperative due to a misplaced crank handle.
