Overview
An airplane was observed performing aerobatic maneuvers over a valley where a 'Hog Roast' party was in progress. The aircraft was not approved for aerobatics according to its Pilot Operating Handbook.
Witness Observation
A witness reported seeing the airplane flying in a manner they described as scary as the airplane performed a loop. The aircraft was conducting maneuvers over the valley during the party.
Pilot Account
The pilot described the maneuver before impact as a 90-degree bank angle with negative g's and too low to the trees. No further details of the pilot's account were provided.
Aircraft Condition
There were no pre-mishap discrepancies found with either the engine or the airframe. The aircraft appeared to be in normal operating condition prior to the event.
Operating Limitations
The Pilot Operating Handbook states that no aerobatic maneuvers are approved for this airplane. The maneuvers being performed were therefore contrary to the aircraft's limitations.
