What happened
During the second leg of a scheduled flight sequence, an aircraft type departed Jakarta for Pekanbaru before preparing for its final leg to Batam. Following a routine transit in Pekanbaru, the crew prepared for departure from Syarif Kasim Airport under clear weather conditions. During the takeoff roll, the crew utilized a reduced takeoff power setting based on an assumed temperature of 35°C, despite the actual ambient temperature being 27° 158 KIAS.
As the aircraft reached rotation speed, the nose lifted, but the aircraft failed to become airborne. During this phase, the crew experienced a stick shaker warning indicating an approaching stall, alongside an illumination of a warning light related to the air conditioning system. Both pilots also reported physical discomfort in their ears. The pilot in command initially attempted to continue the takeoff by increasing power, but as the runway end approached, the decision was made to abort the takeoff.
Upon applying brakes and reverse thrust, the aircraft's nose descended heavily. The force of the deceleration caused the front left door to open and caused galley trolleys to shift forward, obstructing the cockpit door. The aircraft veered off the right side of the runway, striking approach lights and several trees before coming to a halt approximately 275 meters beyond the runway end. The accident resulted in one serious injury and several minor injuries, with no fatalities reported. The aircraft was a total loss.
Findings
- The crew utilized a reduced takeoff power setting based on an incorrect temperature assumption.
- The aircraft failed to achieve flight following rotation due to insufficient performance parameters.
- The heavy nose-down movement during the aborted takeoff led to the structural displacement of galley equipment and the opening of a cabin door.
