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 acft passed over the arpt twice after departure with the engine popping and backfiring. A witness who heard this radioed the plt to warn him. The plt replied that he was trying to correct it with the mixture control. The plt was also advised that his radio had background noise and a squeal. The plt replied that it must be the operator. Theacft then flew out of sight. Another witness heard the engine backfiring and looked in time to see parts falling off of the acft. The acft crashed inverted. The main wings were found 165 and 300 ft from the fuselage. Investigation revealed that the plt had installed a modified wing fuel tank in the foam filled wing and the use of auto gas had dissolved the foam filling by a leak, spillage, or overflow. The foam was tested with avgas and no damage resulted.
