Probable cause

failure of the carburetor heat box flapper valve, and the resultant air flow restriction to the carburetor. A factor relating to the accident was: high vegetation in the area where the forced landing was executed.

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.

Loss of engine power(total) - mech failure/malfTakeoff - initial climb
Carburetor heat,air box - failureCause
Ram/induction air - flow restrictedCause
Forced landingEmergency landing after takeoff
In flight collision with terrain/waterEmergency landing after takeoff
Terrain condition - high vegetationFactor

Analysis

During the initial climb after takeoff, the aircraft experienced a complete loss of engine power at about 200 feet above ground level (AGL). The pilot maneuvered the aircraft to a forced landing in high vegetation, where it received substantial damage during touchdown. An inspection of the engine revealed that the carburetor heat box flapper valve had broken off and was restricting air flow in the carburetor throat.

Factual narrative

On August 5, 1996, approximately 1130 Pacific daylight time, a Piper PA-12, N2564M, registered to and being flown by a private pilot, was substantially damaged during a forced landing into high vegetation following a total loss of power during the initial climb after takeoff from the Astoria Airport, Astoria, Oregon. The pilot sustained minor injuries. Visual meteorological conditions prevailed and no flight plan had been filed. The flight, which was personal, was to have been operated under 14CFR91, and was destined for Troutdale, Oregon. The ELT was activated by the impact.

The pilot reported that he executed a mid-field takeoff from runway 26, and while climbing through 200 feet above ground level (AGL), the engine abruptly stopped. Unable to achieve a restart, he executed a forced landing into an area of heavy brush slightly west of the upwind end of runway 26.

An FAA monitored engine inspection determined that the carburetor heat box flapper valve had broken loose and moved into a position where it restricted the airflow in the carburetor throat.
