## Probable cause

THE CIRCUMFERENTIAL ON THE NUMBER 2 CYLINDER WHICH RESULTED IN A LOSS OF ENGINE POWER.

## Sequence of events

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

- Loss of engine power, cruise
  - engine assembly,cylinder - cracked (cause)
- Forced landing, takeoff - initial climb
  - load jettison
- Nose over, landing - roll
  - terrain condition - soft (contributing factor)
  - terrain condition - wet (contributing factor)

## Analysis

WHILE RETURNING TO A FIELD FOR AERIAL APPLICATION, THE ENG LOST POWER. THE PLT DUMPED THE CHEMICAL LOAD & LANDED IN A MUDDY FIELD. DURING THE LANDING, THE ACFT NOSED OVER & WAS DAMAGED. AFTER THE ACCIDENT, AN EXAM OF THE ENG REVEALED A CIRCUMFERENTIAL CRACK ON THE #2 CYLINDER.
