A Cielos del Peru SA McDonnell Douglas DC-10-30 freighter on behalf of Qatar Airways, registration N614GC performing flight QR-8505 from Macau (Macau) to Karachi (Pakistan), had planned to depart Macau via runway 16 with a flap setting of 17 degrees, due to delay in loading the cargo the aircraft departed with a delay of two hours via runway 34, however, used flaps 14, winds were from 140 degrees at 7 knots with an effective tail wind component of 5 knots. The aircraft used almost the full length of the runway and climbed out very slowly. When the aircraft overflew the localizer antenna, tower received a localizer malfunction alert and the ILS was automatically shut down. A runway inspection confirmed an approach light, about 25 meters/80 feet past the runway end, had been taken out, the localizer antenna had been damaged by some impact and the ILS near field monitoring antenna about 53 meters/170 feet past the runway end was damaged. One localizer antenna element was spread over the airport service road. The information about localizer damage was relayed to the aircraft via China's ATC, the captain reported aircraft operations were normal. The aircraft continued to Karachi where the aircraft landed without further incident.

A post flight inspection revealed cuts in two tyres (#1 and #5, forward and rear left), both tyres held their pressure. The wheels were replaced.

While researching another accident (see Accident: Capital Beijing A320 at Macau on Aug 28th 2018, dropped nose wheels on hard touchdown) The Aviation Herald found out, that Macau's Civil Aviation Authority (MCAA) had released their final report some time in the past concluding the probable cause of the serious incident was:

With the evidence as documented in the available information, the performance of the aircraft was degraded translating into longer take-off roll distance due to incorrect flap setting (14 degrees) for the tail wind condition (140/07 knots).

Contributing Factors

The flight crew had not been provided with sufficient technical and guidance information nor were they adequately trained to apply the correct flap setting for take-off.

The MCAA analysed the aircraft was properly loaded with takeoff weight and CG within permitted limits. The cargo was re-weighed at Karachi to ensure there was no overweight condition. Pakistan's Civil Aviation Authority found cuts in two tyres after landing in Karachi.
