## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - landing gear,main gear strut - separation (contributing factor)
  - landing gear,main gear strut - overload (cause)
  - design stress limits of aircraft - exceeded, pilot in command (cause)
- In flight collision with terrain/water, landing - flare/touchdown
  - wheels up landing - performed, pilot in command (cause)

## Analysis

THE PLT STATED THAT WHILE DOING TOUCH-AND-GO LANDINGS AT QUINCY, FL, THE LEFT MAIN STRUT FELL OFF THE ACFT. HE THEN RETURNED TO TALLAHASSEE AND MADE AN INTENTIONAL GEAR-UP LANDING. EXAMINATION OF THE MAIN LANDING GEAR SCISSOR ASS'Y REVEALED THAT IT FAILED DUE TO OVERLOAD CONDITIONS.
