At 1028 LT, the PM requested pushback and engine start clearance from Halim Tower. After taxi clearance at 1031 LT, the aircraft backtracked Runway 24 at 1047 LT. At 1051 LT, the PM reported ready for departure, and the controller issued takeoff clearance with a departure instruction to turn left to heading 180° and climb initially to 3,000 feet. The takeoff used reduced thrust via an assumed temperature of 40°C, and the aircraft became airborne at 10:52:57 LT. At 1055 LT, the PM reported a right engine failure and requested to fly to AL NDB. The controller cleared them to turn left heading 060° and climb to 2,500 feet. The PM stated no fire was detected. The controller instructed the aircraft to hold over AL NDB at 2,500 feet and informed Airport Rescue and Fire-Fighting (ARFF) of the engine failure and planned return. The PM indicated a holding time of about 15 minutes. At the controller's suggestion, the aircraft held 15 to 20 Nm from AL NDB at 2,500 feet to manage traffic.
