An ATR 72-212A aircraft, registered as PK-WGF, was being operated by PT. Wings Abadi Airlines (Wings Air) on 31 May 2022 from Zainuddin Abdul Madjid International Airport, Lombok, Indonesia (WADL) to I Gusti Ngurah Rai International Airport, Bali, Indonesia (WADD). On board in this flight were two pilots, two flight attendants and 68 passengers.

The aircraft departed from Lombok and flew at cruising altitude of 8,000 feet. The Pilot in Command (PIC) acted as Pilot Flying (PF) while the Second in Command (SIC) acted as Pilot Monitoring (PM).

The flight was uneventful until landing on Runway 09 at Bali, at 1419 LT (0619 UTC). After touched down, the aircraft was instructed by the tower controller to exit the runway via Taxiway N4. While the aircraft was on Taxiway N4, the pilot was instructed by the tower controller to contact ground controller. The ground controller instructed the aircraft to continue the taxi by following the aircraft that was pushing back from parking stand A22 to Runway 09 for departure.

After the aircraft exited Taxiway N4 and taxied on apron taxiway, the SIC asked the assigned parking stand to the ground controller and was informed to park on Parking Stand A41. The aircraft continued taxiing and turned toward Taxiway NW6. The SIC realized that the aircraft had turned toward the wrong taxiway and informed to the PIC. The SIC then confirmed to the ground controller whether the assigned parking stand was A41. The ground controller affirmed and instructed the pilot to continue taxi via Taxiway NW7. While the SIC communicating with the ground controller, the PIC turned the aircraft to the left toward taxiway NW7. The aircraft main wheels stuck in the apron’s ditch.
