## Sequence of events

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

- Gear collapsed, landing
  - gear extension - initiated, pilot in command
  - gear down and locked - not attained, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)

## Analysis

UPON LANDING THE NOSE GEAR WAS DOWN & LOCKED, BUT BOTH MAIN GEAR COLLAPSED. THE PLT WAS NOT CERTAIN IF A DOWN & LOCKED INDICATION WAS RECEIVED BEFORE TOUCHDOWN. DURING A GEAR RETRACTION/EXTENSION TEST AFTER THE ACCIDENT, THE GEAR OPERATED NORMALLY. ALSO, THE LANDING GEAR INDICATORS & WARNING SYS OPERATED NORMALLY.
