AFVOA Newletter August 2020

Section 5 - Memoirs CV 2 No. 02 / 2020 Page 138 of 237 similar AN12 aircraft was brought onto the tarmac. I asked the ground crew to lower the flap of the aircraft to 35 degrees and “delink a link” which I suspected to have failed in the flap system. Then I asked the ground crew to manually push the flap up. The left wing flap remained firm while the right wing flap went up immediately. In such an eventuality the Left Wing of the aircraft will generate more lift when compared to the Right Wing making the aircraft to roll uncontrollably to the right. This was the cause of the accident. The Court accepted my point of view. On our return to HQ WAC the Court reassembled, and on the basis of my evidence, the findings and recommendations were changed. The cause of the accident was the weak link in the critical area of the flap system. On the basis of the recommendations, a Service Instruction was issued to inspect all aircraft and introduce measures to avoid such failures in future. This will save a lives and aircraft.
