Aircraft Accident/Incident Report

Forest Grove, Oregon 97116
Sunday, October 8, 1995 16:40 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot of the RV-3 initiated a steeply banked right turn, after following another aircraft in a rapid climbing maneuver. During this turn, which was described by witnesses on the ground as extremely tight, the right wing was seen to separate from the fuselage. Examination of the wreckage revealed that the front wing spar had failed just outboard of its attach fitting, and the rear spar and rear spar doubler plate experienced a overstress separation through the attach bolt hole. The recording accelerometer found in the wreckage was indicating .2 G's more than the 9 G ultimate load limit published by the designer of the RV-3 aircraft plans.

NTSB Probable Cause Narrative

The pilot exceeded the design stress limit of the aircraft, followed by the failure of the right wing main spar.
