Incident Overview
During a previous flight, a landing gear malfunction occurred. A mechanic inspected the gear and decided to ferry the aircraft to another airport for maintenance with the gear extended. On the subsequent flight, the crew did not exceed the gear-down speed limitation.
Landing Sequence
While landing, the aircraft touched down on the main landing gear approximately 10 feet short of the runway surface. The impact caused the aircraft to bounce. On the second touchdown, the left main landing gear collapsed.
Post-Accident Examination
An examination of the landing gear system revealed that the brushes inside the landing gear power pack were completely worn. No other pre-crash landing gear problems were identified.
