Probable cause
The fracture of the section gear in the main landing gear retraction and extension mechanism.
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 flight was a local training flight. At the completion of the flight, as the pilot attempted to lower the landing gear, the left main landing gear would not extend to the locked position. Investigation of the landing and retraction mechanism revealed that the section gear in the pivot assembly had sheared.
