## Sequence of events

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

- Main gear collapsed, landing - roll
  - landing gear,gear locking mechanism - other (cause)
  - maintenance,adjustment - improper, other maintenance personnel (cause)
  - gear extension - performed, pilot in command
  - landing gear,gear locking mechanism - unlocked (cause)

## Analysis

THE PILOT REPORTED THAT BEFORE LANDING, THE LANDING GEAR INDICATORS SHOWED THAT ALL GEAR WERE DOWN AND LOCKED. HOWEVER, ON THE LANDING ROLL-OUT, THE LEFT MAIN GEAR COLLAPSED AS THE NOSEWHEEL WAS LOWERED TO THE RUNWAY. SUBSEQUENTLY, THE LEFT WING, LEFT PROPELLER, AND LEFT ELEVATOR WERE DAMAGED. WHEN TESTED, THE LANDING GEAR EXTENSION/RETRACTION MECHANISM OPERATED NORMALLY. HOWEVER THE LEFT LANDING GEAR SIDE BRACE LINK WAS FOUND TO BE IMPROPERLY ADJUSTED. ACCORDING TO A MANUAL FOR THIS AIRCRAFT, THE SIDE BRACE LINK SHOULD REQUIRE 50 LBS TO MOVE IT OUT OF THE LOCKED POSITION. HOWEVER, THE LINK COULD BE MOVED WITH LIGHT FINGER PRESSURE, ESTIMATED LESS THAN 5 LBS.
