History of the Flight
On 31 May 2022, an ATR 72-212A aircraft, registered as PK-WGF, operated by PT Wings Abadi Airlines (Wings Air), was conducting a flight from Zainuddin Abdul Madjid International Airport, Lombok, to I Gusti Ngurah Rai International Airport, Bali. The aircraft carried two pilots, two flight attendants, and 68 passengers. The Pilot in Command (PIC) acted as Pilot Flying (PF) and the Second in Command (SIC) acted as Pilot Monitoring (PM).
The flight was uneventful until landing on Runway 09 at Bali at 1419 local time (0619 UTC). After landing, the tower controller instructed the aircraft to exit the runway via Taxiway N4. While on Taxiway N4, the pilot was told to contact ground control. The ground controller directed the aircraft to continue taxiing, following another aircraft that was pushing back from parking stand A22 for departure.
After exiting Taxiway N4 and taxiing on the apron taxiway, the SIC requested the assigned parking stand from the ground controller and was informed to park at Parking Stand A41. The aircraft continued taxiing and turned toward Taxiway NW6. The SIC realized that the turn was incorrect and informed the PIC. The SIC then confirmed with the ground controller that the assigned stand was A41; the controller affirmed and instructed the aircraft to continue via Taxiway NW7. While the SIC was communicating, the PIC turned the aircraft left toward Taxiway NW7. The aircraft's main wheels became stuck in an apron ditch.
Damage to Aircraft
The aircraft suffered substantial damage. Marks from the main wheels were observed on the apron surface. The ditch's metal structure covers were damaged, and a crack appeared on the lower fuselage aft of the main landing gear compartment.
Personnel Information
The PIC held an Airline Transport Pilot License (ATPL) with appropriate type ratings. The SIC held a Commercial Pilot License (CPL). Both pilots were qualified for the flight. Two flight attendants and the ground controller were also involved.
Meteorological Information
The report mentions meteorological information was collected but does not provide specifics in the preliminary report.
Aerodrome Information
The incident occurred at I Gusti Ngurah Rai International Airport, Bali. The aerodrome chart was available in the cockpit. The taxi route from N4 to Parking Stand A41 included apron taxiways, Taxiway NW6, and Taxiway NW7.
Flight Recorders
The aircraft was equipped with a Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR). Data from these recorders was collected for the investigation.
Safety Actions
The airport operator and aircraft operator have taken safety actions. The airport operator repaired the ditch metal structure and repainted apron markings. Additional markings were added on paved shoulders near Taxiways NW6 and NW7. Taxiway edge markings were added, and parking stand numbers and taxiway identifications were painted. The aircraft operator issued a Notice to Pilots.
No safety recommendations were issued by the KNKT as the safety actions were considered relevant.
Ongoing Investigation
The investigation is continuing, and the KNKT plans to complete it within 12 months from the occurrence date. Further safety issues will be addressed as necessary.
