were suspended by the government in response to the accident. Experts believe that the accident may have been caused by weak co-ordination between ATC, the tow truck crew, and Flight 7703's crew and stated that if Flight 7703 was travelling at high speed, the incident could have been similar to the Tenerife Airport disaster in 1977. The flight recorders, either the cockpit voice recorder or the flight data recorder, from the ATR 42, did not provide any data as there was no electrical power at the time of the accident. Therefore, the NTSC could only retrieve the flight recorders from the Boeing 737, which was supported with AC electrical power at the time. The NTSC stated that because the towed ATR 42 did not have electrical power, none of the lights inside and outside the aircraft were on. Radio communication was also off, therefore the ground crew of the towed ATR 42 could only communicate to the Tower through the handheld radio communication. Flight 7703 was communicating with the tower on frequency 118.6 MHz. The communications were recorded by ground-based, automatic, voice-recording equipment and the CVR with good quality; while the towed ATR 42 was communicating on frequency 152.7 MHz. The communications in the ATR 42 were not recorded. Based on interview of the ground crew, the towed ATR 42 requested for a reposition to the south apron. When Flight 7703 was pushed back, the towed aircraft was instructed by Halim Tower unit to continue towing and report taxiway "C”. The absence of lighting on the ATR 42 made it impossible for the air traffic controller to notice the movement of the aircraft, knowing that it was night, aggravated by light shower in Halim Airport. The assistant controller could only see the lights from the towing vehicle. At this point, the towing car driver stated that he saw Flight 7703 was lining up for takeoff then asked to the Halim Tower whether Flight 7703 was initiating the takeoff, but there was no reply from the Halim Tower. Fearing that Flight 7703 would take off, the towing car driver then speeds up the towing and turned to the right side of the runway. The pilot stated that during line up, the lights surround the turn pad were very bright and affected his forward vision for a short time. It was common practice in Halim to line-up at the turn pad beyond
