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.
Analysis
The pilot reported that the engine lost power at about 5 ft AGL as he was taking off from a trailer. He turned to avoid a gas and water tank near the poll truck. The helicopter came to rest, right-side-up, but was damaged. A fuel leak was found in a line that attached to the fuel injector regulator. The leak occurred where the line was flared for a b-nut connection. A metallurgical examination revealed that cracks occurred from stress corrosion.
