## Sequence of events

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

- Airframe/component/system failure/malfunction, landing - roll
  - landing gear,normal brake system - failure,partial (cause)
- Loss of control - on ground/water, landing - roll
- Gear collapsed, landing - roll
  - landing gear,main gear - overload
  - ground loop/swerve - intentional

## Analysis

THE PILOT REPORTED THAT HE HAD JUST LANDED WHEN THE LEFT BRAKE FAILED. IN ORDER TO AVOID HITTING TRUCKS PARKED NEAR THE RUNWAY THE PILOT ELECTED TO GROUND LOOP THE AIRCRAFT. THE SIDE LOADING ON THE LEFT LANDING GEAR DURING THE GROUND LOOP CAUSED IT TO COLLAPSE. EXAM OF AIRCRAFT BY THE FAA REVEALED THAT THE LEFT BRAKE HAD SUBSTANTIAL HYDRAULIC FLUID COVERING THE BRAKE ASSEMBLY.
