## Probable cause

The partial loss of engine power due to a cracked cylinder head.  Factors were the oil leak which restricted the pilot's visual lookout and the lack of suitable terrain for the forced landing.

## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, takeoff - initial climb
  - engine assembly,cylinder - cracked (cause)
- Forced landing, emergency landing after takeoff
- In flight collision with object, emergency landing after takeoff
  - fluid,oil - leak (contributing factor)
  - visual lookout - restricted, pilot in command (contributing factor)
  - terrain condition - none suitable (contributing factor)
  - terrain condition - high vegetation
- Nose down, landing - roll

## Analysis

The pilot reported that during the airplane's takeoff climb, the engine lost power, and the windshield became coated with oil.  The pilot 'immediately began a shallow right turn attempting to return to the airstrip.'  During the descent, the airplane's spray boom caught the tall weeds 'causing a loss of airspeed.'  The airplane impacted the ground short of the runway threshold and came to rest on its nose.  The engine separated from the airframe, all four wings were damaged, and the landing gear separated from the fuselage.  The salvage yard owner who performed a partial engine examination and tear down reported finding metal throughout the engine and one cylinder head cracked.

## Factual narrative

On September 17, 1996, at 1300 central daylight time, a Schweizer G-164B, N8498K, was substantially damaged during a forced landing following a partial power loss near Ferriday, Louisiana.  The commercial pilot, sole occupant of the airplane, was not injured.  The airplane was registered to a private owner and operated by Ag-Cats Inc. under Title 14 CFR Part 137.  Visual meteorological conditions prevailed for the aerial application flight which was originating from a private agricultural airstrip at the time of the accident.  A flight plan was not filed for the local flight.

The pilot reported that during the airplane's takeoff climb, the engine lost power, and the windshield became coated with oil.  The pilot "immediately began a shallow right turn attempting to return to the airstrip."  During the descent, the airplane's spray boom caught the tall weeds "causing a loss of airspeed."  The airplane impacted the ground short of the runway threshold and came to rest on its nose.  The engine separated from the airframe, all four wings were damaged, and the landing gear separated from the fuselage.

The IIC interviewed the salvage yard owner who performed a partial engine examination and tear down.  He reported finding metal throughout the engine and one cylinder head was cracked.

Probable cause: the failure of the number three cylinder exhaust rocker arm, resulting in a total loss of engine power. A contributing factor was the lack of suitable terrain for the forced landing.
