## 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, takeoff - initial climb
  - ignition system,magneto - incorrect (cause)
  - maintenance,inspection - improper, other maintenance personnel (cause)
  - ignition system,magneto - loose (cause)
  - maintenance,adjustment - improper, other maintenance personnel (cause)
- Forced landing, landing - flare/touchdown
  - wheels up landing - intentional, pilot in command (cause)

## Analysis

THE ACFT MADE A FORCED LANDING SHORTLY AFTER TAKEOFF WHEN THE ENGINE FAILED. WHILE CLIMBING THROUGH 200 FT AGL THE ACFT LOST POWER. THE PLT MADE A GEAR UP LANDING. THE ENGINE WAS EXAMINED AFTER THE ACCIDENT AND THE MAGNETO TIMING WAS FOUND TO BE INCORRECT. ALSO THE MAGNETO CAM RETAINING SCREW WAS LOOSE. THIS ACFT HAS A DUAL MAGNETO WITH ONE DRIVE. THEREFORE THE LOOSE SCREW ALLOWED BOTH MAGS TO BE OUT OF TIME RESULTING IN POWER LOSS OR ENGINE FAILURE. AFTER THE MAGNETOS WERE TIMED THE ENGINE RAN NORMALLY.
