Aircraft Accident/Incident Report

Rio Hondo, Texas 78583

NTSB Narrative Summary Released at Completion of Accident

A witness observed the Bell 206-A helicopter 'flying fast' in a southerly direction at about 500 to 600 feet agl. Flames were coming from the helicopter's right rear side in the vicinity of the engine compartment, and very little smoke was observed. Prior to descending from view, the helicopter appeared to be in controlled flight. Subsequently, the aircraft impacted the ground and was destroyed by the in-flight and postimpact fire. Examination of the engine compartment revealed that the step portion of the forward firewall where the throttle and fuel line pass through had localized bluing; however the fuel line connector which was still attached to the firewall fitting, did not exhibit any fire damage. The #3 tail rotor drive shaft segment was found 66 feet prior to the initial impact scar. It was fractured with fire damaged fiberglass cloth wrapped around the forward end of the fractured shaft. According to a NTSB metallurgist, 'the fracture was consistent with an overstress after exposure to elevated temperatures.' The helicopter was returning to Guatemala after completion of schedule maintenance performed in the United States.

NTSB Probable Cause Narrative

The engine compartment fire due to undetermined reasons, which resulted in the in-flight separation of the tailboom.
