## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, maneuvering - turn to landing area (emergency)
- Loss of control - in flight, maneuvering - turn to landing area (emergency)
  - airspeed - not maintained, pilot in command (cause)
  - stall/spin - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

ACCORDING TO WITNESSES, THE ACFT ENTERED A TURN SHORTLY AFTER TAKING OFF FROM A TOUCH-&-GO LANDING, THEN STALLED & BEGAN TO SPIN TO THE RIGHT. THE ACFT IMPACTED THE GROUND AT THE EDGE OF A CANAL, APRX 1000 FT FROM THE DEPT END OF THE RWY. ONE WITNESS STATED THAT THE ENG STOPPED ABRUPTLY BEFORE THE ACFT CRASHED. A POST CRASH EXAM OF THE ENG REVEALED LOW COMPRESSION IN ALL CYLINDERS DUE TO EXCESSIVELY WORN PISTONS; HOWEVER, THE REASON FOR THE POWER LOSS WAS NOT VERIFIED.
