Probable cause

Exceeding the design stress limits of the aircraft while recovering from a loss of control in flight due to spatial disorientation. Factors related to the accident were delayed remedial action and inadequate supervision of an inexperienced pilot by the pilot-in-command, and lack of experience in type of operation by the second pilot.

Analysis

A second pilot who was not instrument rated was flying under the hood in VMC conditions at 6000 feet on a cross country flight. The instrument rated pilot-in-command told him to turn right to avoid a thunderstorm. The second pilot became disoriented in the turn, and entered a spiralling descent into IMC conditions. The pilot-in-command took control and overstressed the aircraft during the recovery. The aircraft was flown to the intended destination and landed without incident. Wing deformation and bent spar was discovered on preflight inspection before the next flight.
