What happened
A flight crew was conducting a routine test flight following recent maintenance work on the aircraft. As the plane reached the point of liftoff, it experienced a sudden left bank. This maneuver caused the aircraft to strike the ground, after which it came to a stop.
There were no injuries reported among the three crew members involved in the incident. However, the aircraft sustained damage that was classified as beyond repair.
Findings
Investigations into the accident revealed that the loss of control was directly linked to improper maintenance procedures. Specifically, technicians at the company had incorrectly reconnected the aileron cables during the maintenance process prior to the commencement of the test flight.
