## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - brakes(normal) - improper use of, pilot in command (cause)
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
- Main gear collapsed, landing - roll
  - landing gear,main gear strut - overload

## Analysis

THE PLT LOST CONTROL OF THE ACFT DURING THE LANDING ROLL, & SUBSEQUENTLY, ONE OF THE MAIN LANDING GEAR COLLAPSED. HE STATED THAT HE APPLIED THE LEFT 'DRAG BRAKE' (A BRAKING DEVICE ACTIVATED DURING THE LAST PORTION OF RUDDER TRAVEL) & OVERCORRECTED TO THE LEFT. HE THEN ACTIVATED THE RIGHT 'DRAG BRAKE' & OVERCORRECTED TO THE RIGHT. THIS RESULTED IN A GROUND LOOP & ACFT DAMAGE.
