Circumstances:
PK-MJD was on passenger schedule flight from Sultan Hasanuddin Airport, Makassar with destination El Tari Airport, Kupang, East Nusa Tenggara. The flight number was Merpati 5840 and carried 94 person on board consist of 88 passengers including four children and four infants, two pilot and four flight attendant. A maintenance engineer was on-board in this flight. Acting as pilot flying was the Second in Command (SIC) while the Pilot in Command acted as Pilot Monitoring. On approach, the pilot selected landing gear to down position. The left main landing gear
indicator light was showed red, its means that the left main landing gear was not in down position and unsafe for landing. The pilot reported to the Air Traffic Controller (ATC) for a go-around and requested an area for holding to solve the problem. The ATC gave a clearance to hold over Kupang bay. The pilot tried to solve the problem by conducting the procedure according to the emergency checklist, including selected the landing gear by alternate selector. The pilot then requested to the ATC to fly at low altitude over the airport and asked to the ATC to observe the landing gear condition. The pilot also asked through the company radio for an engineer on-ground to observe visually the landing gear condition. The pilot then returned to the holding area, repeated the procedure but unsuccessful. Both pilots and engineer had a discussion and decided to attempt un-procedural method to make the landing gear down. Prior making these efforts the pilot announced to the passengers about the problem and their attempts that might be unpleasant to the passengers. After all attempts to lower the landing gear had failed, the pilot decided to land with the left main landing gear in up position. The pilot also asked the flight attendant to prepare for an abnormal landing. The ATC were prepared the airport fire fighting and ambulance, and also contacted the local police, armed forces, and hospitals and asking for additional ambulances. The ATC then informed the pilot that the ground support was ready. On short final the pilot instructed ‘brace for impact’ and the FA repeated that instruction to all passengers. The aircraft touched down at the touch down zone on runway 07. The pilot flying held the left wing as long as possible and kept the aircraft on the centre line, and the pilot monitoring shut down both engines. The aircraft stopped at about 1,200 meters from the beginning of runway 07, on the left shoulder of the runway and the FA instructed to the passengers to keep calm and to evacuate the aircraft. The pilot continued the procedures for emergency. The evacuation was performed through all door and window exits. No one was injured on this serious incident.
Probable cause:
The debris trapped in the chamber between the orifice and the stopper of the restrictor check valve, it caused the orifice closed. This condition was resulted the hydraulic flow from the actuator blocked and caused the left main landing gear jammed at up position.

Circumstances:
Lion Mentari Airline (Lion Air) as flight number LNI-793, departed from Sultan Hasanuddin Airport (WAAA), Makassar, Ujung Pandang, Sulawesi at 0636 UTC for Soekarno-Hatta International Airport (WIII), Jakarta. The estimated flight hour from Makassar to Jakarta was 2 hours. The crew consisted of two pilots and four flight attendants. There were 166 adult passengers. The copilot was the pilot flying for the sector, and the pilot in command (PIC) was the support/monitoring pilot. During the approach to runway 25L at Jakarta, the weather at the airport was reported as wind direction 200 degrees, wind speed 20 knots, visibility 1,000 meters, and rain. The PIC reported that he decided to take over control from the copilot. The PIC later reported that he had the runway in sight passing through 1,000 feet on descent, and he disengaged the autopilot at 400 feet. At about 50 feet the aircraft drifted to the right and the PIC initiated corrective action to regain the centreline. The aircraft touched down to the left of the runway 25L centerline and then commenced to drift to the right. The PIC reported that he immediately commenced corrective action by using thrust reverser, but the aircraft increasingly crabbed along the runway with the tail to the right of runway heading. The investigation subsequently found that the right thrust reverser was deployed, but left thrust reverser was not deployed. The aircraft stopped at 0835 on the right side of the runway 25L, 1,095 meters from the departure end of the runway on a heading of 152 degrees; 90 degrees to the runway 25L track. The main landing gear wheels collapsed, and still attached to the aircraft, were on the shoulder of the runway and the nose wheel was on the runway. The passengers and crew disembarked via the front right escape slide and right emergency exit windows. None of the occupants were injured
Probable cause:
The aircraft was not stabilized approach at 100 feet above the runway.

Circumstances:
On 1 January 2007, a Boeing Company 737-4Q8 aircraft, registered PK-KKW, operated by Adam SkyConnection Airlines (AdamAir) as flight number DHI574, was on a scheduled passenger flight from Surabaya (SUB), East Java to Manado (MDC), Sulawesi, at FL350 (35,000 feet) when it disappeared from radar. The aircraft departed from Djuanda Airport, Surabaya at 05:59 Coordinated Universal Time (UTC) under the instrument flight rules (IFR), with an estimated time of arrival (ETA) at Sam Ratulangi Airport, Manado of 08:14. The fuel endurance on departure from Surabaya was hours 30 minutes, and the crew had flight planned for an alternate of Gorontalo (GTO). The pilot in command (PIC) was the pilot flying for the sector to Manado and the copilot was the monitoring/support pilot. There were 102 people on board; two pilots, 4 cabin crew, and 96 passengers comprised of 85 adults, 7 children and 4 infants.
Probable cause:
The following findings were identified:
1) Flight crew coordination was less than effective. The PIC did not manage the task sharing; crew resource management practices were not followed.
2) The crew focused their attention on troubleshooting the Inertial Reference System (IRS) failure and neither pilot was flying the aircraft.
3) After the autopilot disengaged and the aircraft exceeded 30 degrees right bank, the pilots appeared to have become spatially disoriented.
4) The AdamAir syllabus of pilot training did not cover complete or partial IRS failure.
5) The pilots had not received training in aircraft upset recovery, including spatial disorientation.
Other Causal Factors:
1) At the time of the accident, AdamAir had not resolved the airworthiness problems with the IRS that had been reoccurring on their Boeing 737 fleet for more than 3 months.
2) The AdamAir maintenance engineering supervision and oversight was not effective and did not ensure that repetitive defects were rectified.

Circumstances:
Following an uneventful flight from Jakarta, the crew started the descent to Makassar (Ujung Pandang) Airport. On approach to runway 31, flaps were selected down from 15° to 30° when the captain observed an asymmetrical condition between both flaps and decided to set back at 15° and to continue the approach in such conditions. The aircraft landed hard to the left of the runway centerline and bounced twice. Out of control, it veered off runway, lost its right main gear and came to rest few dozen metres further. All 164 occupants evacuated safely while the aircraft was damaged beyond repair as the left main gear punctured the fuel tank and the fuselage was deformed.
Probable cause:
The exact cause of the asymmetrical flaps condition on approach is undetermined. Since all the conditions were clearly not met, the pilots should have made the decision to initiate a go-around procedure.
