An air test of Otter 3666 was planned following repairs on the port inner trailing edge flap. The airplane took off from runway 09 at 18:54 and climbed straight ahead. A sudden spontaneous full flap retraction caused the nose of the aircraft to drop. Loads on the wing exceeded the design strength, causing the left hand wing to break off. It struck the tailplane, causing the Otter to crash out of control.
Classification:
