## Sequence of events

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

- Main gear collapsed, landing - flare/touchdown
  - landing gear,gear locking mechanism - failure,total (cause)

## Analysis

N81PH WAS RETURNING FROM A TEST FLIGHT AND WHEN THE LANDING GEAR WAS LOWERED THE RIGHT MAIN GEAR FAILED TO LOCK. THE GEAR WAS CYCLED SEVERAL TIMES WITHOUT SUCCESS. DURING TOUCHDOWN THE RIGHT MAIN GEAR COLLAPSED AND THE AIRCRAFT CAME TO REST OFF THE RUNWAY. EXAMINATION OF THE LANDING GEAR REVEALED THAT THE GEAR LOCKING DEVICE FAILED TO ACTUATE WHEN THE GEAR WAS EXTENDED.
