## Sequence of events

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

- Main gear collapsed, landing - roll
  - in-flight planning/decision - poor, pilot in command (cause)
  - gear extension - delayed, pilot in command (cause)

## Analysis

THE PILOT INDICATED THAT THE LEFT MAIN GEAR COLLAPSED DURING LANDING ROLLOUT. THE PILOT DID NOT RESPOND TO THE FOLLOWING QUESTIONS, WHEN ASKED DURING A TELEPHONE INTERVIEW, 'WHEN WAS THE GEAR PLACED DOWN? AND WHAT DID THE GEAR SAFE INDICATOR LIGHTS INDICATE AT TOUCHDOWN? ALL THE PILOT WOULD STATE IS THAT HE FOLLOWED THE CHECKLIST. THE CHECKLIST STATES GEAR SHOULD BE DOWN PRIOR TO 'WHEN LANDING ASSURED.' EXAM OF THE ACFT REVEALED ROTATIONAL SCORING ON THE PAINTED SURFACE OF THE LEFT MAIN GEAR ACTUATOR ASSEMBLY. FURTHER COMPONENT TEARDOWN AND EXAM REVEALED THAT THE SCREW HOUSING ASSEMBLY OF THE ACTUATOR WAS BENT.
