Aircraft Accident/Incident Report
Boone, North Carolina 28607
Friday, July 7, 2000 11:00 EDT
NTSB Narrative Summary Released at Completion of Accident
During takeoff rotation, engine power decreased and the pilot heard an unusual noise from the engine area. The pilot was unable to stop on the remaining runway and proceeded away from the airport and made a 180 degree turn to return to the airport. The engine did not produce enough power to return to the runway and the aircraft was landed in the grass adjacent to the runway. During rollout the nose landing gear collapsed and the aircraft impacted a mound of dirt where it came to rest. Post crash examination of the aircraft by an FAA inspector showed the engine inter-cooler system, which had been installed in accordance with an STC, was loose at the worn single attach point and the rubber duct from the inter-cooler to the engine was split about 50% around, causing turbocharged air to be exhausted overboard. The aircraft had received an annual inspection about 1 flight hour before the accident. Documents for the inter-cooler system did not give any directions for inspecting the system.
NTSB Probable Cause Narrative
The failure of the inter-cooler duct connecting the inter-cooler to the engine due to inadequate attachment of the inter-cooler to the aircraft which resulted in loss of turbocharger air overboard and loss of engine power and damage to the aircraft during a forced landing. Contributing to the accident was inadequate inspection requirements for the inter-cooler system and inadequate inspection of the inter-cooler system by the mechanic during the last inspection.
