Probable cause
That maintenance personnel failed to properly install the wings by not reconnecting the bolts at the bellcrank and performed an inadequate annual inspection.
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 CFI and noncertificated student pilot departed goodyear, AZ, on a dual instructional flight. While practicing ground reference maneuvers the airplane sustained a loss of aileron control. The CFI executed a forced landing into a drywash. The airplane collided with a berm during the landing roll. The wreckage examination disclosed that one of the aileron cables disconnected from the bellcrank. The connecting nut and bolt was not located. Another bolt, although attached to the bellcrank, did not contain a corresponding nut. Both wings were reinstalled on the airplane about 22 months before the accident. The last annual inspection was performed about 3 months before the accident. The same mechanic performed the reinstallation of both wings and the last annual inspection.
