As we already know, accidents Sukhoi Superjet 100 (SSJ-100) on Mount Salak in Bogor which occurred in May 9, 2012 was busy talking. The aircraft was lost on a flight demonstration kloter to-2. Yet when the first kloter travel smoothly without interruption. Flights kloter to-2 departed from Halim Perdanakusuma airport, Jakarta, Indonesia. Lapse 1 day after that, the ruins look ditebing Superjet 100 Mount Wrong. Due to the vast field of debris where the plane crashed into a mountain, rescuers concluded that direct planes crashed into the side of a rocky mountain and that "there is no chance of survival.

National Transportation Safety Committee (NTSC) concluded that there are three factors that contribute to the causes of the crash Sukhoi RRJ-95B 97 004 Superjet 100 in Mount Salak in Bogor, West Java.

"The investigation NTSC with various parties on Sukhoi crash concluded there were three factors that contributed to the accident," said Chairman of the NTSC Tatang Kurniadi during a press conference at the House of NTSC, Jakarta, Tuesday (18/12/2012).

According to Tatang, the first factor was the flight crew did not realize the condition of the hills surrounding the flight path traversed by several factors and resulting in ignoring the crew of the "Terrain Awareness Warning" (TAWS).

"At 14:26 pm, the pilot requested permission to descend to an altitude of 6,000 feet and to make orbit (circular path) to the right so that the plane is not too high for the landing at Halim using runway 06. Permission was given by the officers 'Jakarta Approach'," he said.

He said 38 seconds before impact, giving TAWS warning sound "Terrain Ahead, Pull Up" and was followed by six times "Avoid Terrain". Pilot in Command (PIC) TAWS deadly because it assumes that the warning was caused by the "database" is problematic.
Secondly, he continued, Jakarta Radar does not have any limits on the minimum altitude aircraft and a given vector of Jakarta Radar systems not equipped with a "Minimum Safe Altitude Warning" (MSAW) which serves to the Mount Salak.

"Radar Jakarta Services does not have any minimum altitude to perform vector in a particular area and MSAW that exist in the system does not provide a warning to officials Jakarta Approach to the plane hit," he said.

He explained that the vector is the command form of the direction given by the air traffic controller to pilot the radar service.

The third or last, he said, there was a distraction to the crew of the conversation is prolonged and associated with the flight.

"Thus causing the pilot to fly the plane did not immediately change the direction of the aircraft when the aircraft out of the orbit and the orbit accidental," he said.
