Overview
Lion Mentari Airline flight LNI-793 departed from Sultan Hasanuddin Airport in Makassar, Sulawesi, at 0636 UTC, bound for Soekarno-Hatta International Airport in Jakarta. The scheduled flight duration was approximately two hours.
Flight and Crew
The aircraft carried a crew of two pilots and four flight attendants, along with 166 adult passengers. The copilot was designated as the pilot flying for the sector, while the pilot in command (PIC) served as the support and monitoring pilot.
Approach and Landing
During the approach to runway 25L at Jakarta, weather conditions were reported as wind from 200 degrees at 20 knots, visibility of 1,000 meters, and rain. The PIC reported that he decided to take over control from the copilot. Passing through 1,000 feet on descent, the PIC had the runway in sight, and he disengaged the autopilot at 400 feet. At approximately 50 feet, the aircraft drifted to the right, prompting the PIC to initiate corrective action to regain the centerline. The aircraft touched down to the left of the runway 25L centerline and then began to drift to the right. The PIC immediately applied thrust reverser, but the aircraft increasingly crabbed along the runway with the tail to the right of the runway heading. Subsequent investigation found that the right thrust reverser was deployed, but the left thrust reverser was not deployed.
Evacuation
The aircraft came to a stop at 0835 on the right side of runway 25L, 1,095 meters from the departure end, on a heading of 152 degrees—approximately 90 degrees to the runway track. The main landing gear wheels collapsed and remained attached to the aircraft, positioned on the runway shoulder, while the nose wheel stayed on the runway. All passengers and crew evacuated via the front right escape slide and right emergency exit windows. None of the occupants were injured.
Investigation Findings
The official probable cause identified that the aircraft was not on a stabilized approach at 100 feet above the runway.
