## Sequence of events

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

  - exhaust system,muffler - failure,total (cause)
  - exhaust system - leak (cause)
  - electrical system,electric wiring - burned (cause)
  - ignition system,magneto - inoperative (cause)
- Loss of engine power(total) - mech failure/malf, takeoff - initial climb
- Forced landing, descent - emergency
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - none suitable (contributing factor)
  - terrain condition - ditch (contributing factor)

## Analysis

DURING INITIAL CLIMB, THE PLT SMELLED SMOKE & HEARD A BACKFIRE, THEN THE ENG LOST POWER. A FORCED LANDING WAS MADE IN A FIELD ON ROUGH/UNEVEN TERRAIN. DURING THE LANDING ROLL, THE ACFT STRUCK A DITCH & WAS DAMAGED. A VISUAL INSPECTION REVEALED THAT THE LEFT EXHAUST MUFFLER HAD FAILED AT ITS OUTLET. THIS ALLOWED HOT EXHAUST GASES TO ENTER THE ENG COMPARTMENT & DAMAGE THE VOLTAGE REGULATOR, ALTERNATOR & MAGNETO WIRING (P-LEADS). WITH P-LEAD FAILURE, THE MAGNETOS WOULD HAVE BEEN INOPERATIVE. AN AIRWORTHINESS DIRECTIVE, AD 76-23-03, WHICH REQUIRED AN INSPECTION OF THE EXHAUST SYS EACH 100 HRS, HAD LAST BEEN COMPLIED WITH ON 8/18/82. HOWEVER THE ACFT HAD BEEN OPERATED FOR ONLY 50 FLT HRS SINCE THAT DATE.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
