## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, cruise - normal
  - aircraft weight and balance - exceeded, pilot in command (contributing factor)
  - ignition system,magneto - failure,total (cause)
  - fuel system,pump - other (cause)
- Forced landing, landing
  - load jettison - performed, pilot in command (contributing factor)

## Analysis

THE PILOT STATED THAT ABOUT 5 MINUTES AFTER TAKEOFF THE ENGINE SKIPPED ONCE, POPPED, THEN QUIT COMPLETELY WITH NO OTHER WARNING. THE AIRCRAFT WAS OVER A WOODED AREA AND WAS FORCED TO LAND IN THE TREES. IT WAS DETERMINED THAT THE AIRCRAFT WAS APPROXIMATELY 740 LBS ABOVE THE MAXIMUM AUTHORIZED GROSS WEIGHT AT TAKEOFF AND WAS OVERWEIGHT AT THE TIME OF THE ENGINE FAILURE. THE PILOT REPORTED THAT HE DUMPED HIS CHEMICAL LOAD PRIOR TO THE CRASH. ENGINE EXAMINATION REVEALED THAT THE LEFT MAGNETO DRIVE GEAR SHAFT, P/N 10538, SHEARED APPROXIMATELY ONE INCH AFT OF THE DRIVE GEAR. THE SHAFT IS NECESSARY TO DRIVE THE ENGINE DRIVEN FUEL PUMP AND THE LEFT MAGNETO.
