## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - landing gear,main gear strut - failure,total (cause)
  - gear extension - not possible, pilot in command (cause)
- Gear not extended, landing - flare/touchdown

## Analysis

THE LT MAIN GEAR WOULD NOT EXTEND WHEN THE PLT ATTEMPTED TO LOWER THE GEAR & AND THE ACFT WAS LANDED IN THAT CONDITION. AN EXAM OF THE STRUT ASSY REVEALED THAT A BEARING, P/N 5041108-1/2 HAD FAILED PERMITTING THE STRUT TO OVEREXTEND, JAMMING THE GEAR IN THE WHEEL WELL. A REVIEW OF FAILURE RECORDS REVEALED THAT OTHER SIMILIAR ACFT USING THIS BEARING HAD HAD SIMILIAR FAILURES RESULTING IN SIMILIAR ACCIDENTS. THE ACFT MANUFACTURER WAS ADVISED & THEY ISSUED A SERVICE LETTER WHEREBY ALL ACFT USING THIS BEARING SHOULD HAVE THE BEARING INSPECTED EVERY 1000 FLT HRS.
