A Lion Air Airbus A330-300, registration PK-LEG performing flight JT-208 from Jakarta to Kuala Namu (Indonesia), landed on Kuala Namu's runway 23 in rainy conditions at about 16:20L (09:20Z) but veered left, the left main gear departed the runway surface for about 30 meters before the crew managed to return the aircraft onto the runway center line. The aircraft rolled out without further incident and taxied to the apron.

A post flight inspection revealed grass on the main wheels and a deep cut in one of the tyres.

Indonesia's KNKT rated the occurrence a serious incident and opened an investigation.

On Nov 24th 2020 the KNKT released their preliminary report summarizing the sequence of events:

At 0714 UTC (1414 LT) the aircraft departed Soekarno-Hatta International Airport, Jakarta and cruised at flight level (FL) 400 (altitude 40,000 feet). The Second in Command (SIC) (46, ATPL, 17,130 hours total, 235 hours on type) was a qualified Pilot in Command (PIC) under line training for standardization training program and occupied the cockpit left seat. The PIC (48, ATPL, 16,916 hours total, 2,216 hours on type) was a qualified instructor occupied the cockpit right seat. The SIC acted as Pilot Flying (PF) while the PIC acted as Pilot Monitoring (PM). The pilot noticed of CB cloud on final runway 05, then requested to change runway to 23 and was rejected by the ATCO.

The SIC handed over the aircraft control to the PIC, considering the weather condition and lesser flying experience on the aircraft type. The PIC refused it and asked the SIC to keep controlling the aircraft.

The pilots noticed that an aircraft ahead made go around due to windshear and a pilot of another aircraft behind LNI 208 requested to change runway to 23 for landing. The pilot informed to the ATCO that on final 05 something that he mentioned as “the big thundercloud” was visible and requested to use runway 23 for landing. The ATCO provided radar vector for LNI208 to point HORAS to performed Instrument Landing System (ILS) approach runway 23.

During approach approximately 1,000 feet, the SIC handed over the aircraft control to the PIC and the PIC became the PF. At 0940 UTC, when the altitude approximately 500 feet, the autopilot disengaged. The SIC advised to the PIC that the wind velocity was 16 knots from 275 degree.

After Flight Management Computer (FMC) call out “RETARD”, the SIC noticed that the aircraft position was getting closer to the left runway edge and advised to the PIC to fly right.

At 0941 UTC, the aircraft touched down and the PIC realigned the aircraft to the runway centerline by applying right rudder pedal.

The left main landing gear travelled out from the runway near the taxiway D and returned to runway centerline near taxiway E. The aircraft vacated runway via taxiway G and parked in parking stand number 14. The pilot reported to Kualanamu Tower controller that they were slightly veered to the left and might hit the runway light. The passengers disembarked normally and no one injured on this occurrence.

During inspection the engineer found grasses on the area left main wheel and found deep cut on the wheel number 5 and number 6. The runway inspection found two runway lights broken.

In the findings the KNKT stated: "During the Covid-19 pandemic the operation department had difficulties to maintained pilot proficiency and recent experience since the aircraft operation reduced and travel limitation issue." and further reported the SIC had not flown in the last 90 days at all, the instructor had flown 2:56 hours in the last 90 days.
