Abnormal Runway Contact, Asia Cargo Airlines (Boeing 737-300F PK-YGV); Bandar Udara Internasional Syamsudin Noor, KNKT.22.08.08.04

On 14 August 2022, a Boeing 737-300F aircraft, registered PK-YGV was being operated by PT. Tri MG-Intra Asia Airlines (Tri MG) on an unscheduled cargo flight from SoekarnoHatta International Airport (WAAA/CGK), Jakarta to Syamsudin Noor International Airport (WAOO/BDJ), Banjarmasin. On board of the aircraft were two pilots, one engineer and one flight operation officer. The Pilot in Command (PIC) acted as Pilot Monitoring (PM), and the Second in Command (SIC) acted as Pilot Flying (PF). The flight was uneventful until the aircraft approached Banjarmasin.

During approach, the pilot noticed that the flap indicator needles split indicating asymmetry, and the aircraft tended to roll to the left. The pilot performed a go around and flew to LIBNU point. The pilot attempted to reconfigure the aircraft by recycling the flap lever but the flap asymmetry issue remained. The pilot then performed non-normal landing procedure.

While the asymmetry remained, the pilot decided to land after completed the non-normal checklist by following the Instrument Landing System (ILS) Runway 10. At 0534 UTC, before touchdown, the aircraft rolled to the left. The left wingtip and engine cowling contacted the runway surface. The pilot managed to level the aircraft, touchdown before stopped on the runway and continued taxiing to the apron.

The aircraft was slightly damaged. There were scratches on lower surface of the left engine cowling, lower surface of left slat leading edge and left wing tip. There were also wrinkles and dents on the upper surface of left wing.

In the initial investigation, KNKT found safety issue in recording and reporting system. Therefore, KNKT provided safety recommendation to the aircraft operator to address identified safety issue.
