TransNusa Aviation Mandiri

On 4 April 2016, Boeing 737-800 registration PK-LBS was being operated by Batik Air as scheduled passenger flight with flight number ID 7703 from Halim Perdanakusuma Airport with intended destination Sultan Hasanuddin International Airport, Makassar. An ATR 42-600 aircraft, registration PK-TNJ operated by TransNusa Aviation Mandiri was being repositioned from north to south apron of Halim Perdanakusuma Airport by a ground handling agent PT. Jasa Angkasa Semesta (PT. JAS). The aircraft was towed without aircraft electrical power fed to the system including the radio communication and aircraft lighting system. At the time of occurrence, the ID7703 pilot communicated to Halim Tower controller on frequency 118.6 MHz while the towing car driver communicated using handheld radio on frequency 152.73 KHz and was handled by assistant controller. At 1948 LT (1248 UTC), ID7703 pilot received taxi clearance from Halim Tower controller and after the ID7703 taxi, the towing car driver received clearance for towing and to report when on taxiway C. Afterward the towing car driver was instructed to expedite and to follow ID7703. While the ID7703 backtracking runway 24, the towed aircraft entered the runway intended to cross and to enter taxiway G. At 1256 UTC, ID7703 pilot received takeoff clearance and initiated the takeoff while the towed aircraft was still on the runway. The towing car driver and the pilots took action to avoid the collision. The decision of the pilot and the towing car driver to move away from the centerline runway had made the aircraft collision on the centerline runway (head to head) avoided, however the wings collision was unavoidable. At 1257 UTC, the ID7703 collided with the towed aircraft. The ID7703 pilot rejected the takeoff and stopped approximately 400 meters from the collision point while the towed aircraft stopped on the right of the centerline runway 24. No one injured at this occurrence and both aircraft severely damaged.
