Probable cause

The loss of engine power due to the valve failure. A factor was the lack of suitable terrain for the forced landing.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot experienced a complete engine failure after takeoff while passing through 200 feet AGL. The airplane subsequently landed in a rough open field as there was no other suitable terrain. Investigation revealed that the no. 1 cylinder exhaust valve had separated and the stem was ingested into the engine. The valve head was found imbedded in the piston head. Due to the level of damage sustained by the valve parts, the exact failure mode could not be determined.
