4 irregularities in the tragedy of the Sukhoi aircraft in BogorQuote:Sukhoi Superjet Jakarta (SSJ) 100 lost contact with Air Traffic Control Cengkareng Soekarno-Hatta Airport on Wednesday (05/09/2012) and the fragments found on Thursday in Mount Salak. Many airlines flight irregularities in the joy of this SSJ-100.
Joy Flight Routes
This discrepancy disclosed Sukardi Ocean aviation observer, who is also a former high-ranking Air Pelita. Joy flight made Sukhoi Superjet100 of Halim Perdanakusuma Airport, Port of Queen's route across the mountains of the dark.It is considered unusual because it is usually done on a joy flight routes that are brighter, which is across the sea.
"For the joy flight should take the route of Krakatoa, passing through the territorial sea of ​​light. But it is through the Port of the Queen, through the dark mountain," said aviation analyst, Ocean Sukardi, when contacted by AFP on Wednesday (8/5/2012) night.
Ocean said, the joy flight or a flight demonstration in the usual sea of ​​bright areas.Both aircraft types of large, medium, to small, such as Bombardier and Cessna Caravan, always crossing the sea.
"So far, the joy flight has never been that way. Always through the territorial sea," he said.
Well, who allowed a strange flight routes that joy?
Ministry of Transportation (Kemenhub) outlining the licensing of foreign aircraft flying in Indonesia. There are two procedures for it.
"To fly in the airspace Indonesia there are three agencies that issue permits. Foreign Ministry for diplomatic clearance, security clearance and Kemenhan for Kemenhub for technical rights and plane transport," explains Head of Public Communication Center Ministry of Transportation (Kemenhub) Bambang S Ervan.
Well for Indonesia and Russia, two countries already have a Bilateral Airworthiness Agreement. That is, recognize certification issued by the civil aviation of each country.
"It makes the basic rights of transport means," he explained.
Then when the procedure has been passed, the procedure then the airline, in this case intermediaries Sukhoi, PT Tri Marga Rekatama and Sukhoi party must file a flight plan to the Air Traffic Service (ATS) which regulates air traffic. Flight plans have 2, the one submitted to the ATS and only brought the pilot.
"Somehow, it should be approved first (the ATS) has taken. If he did not take him to fly to," said Bambang licensing issues will also be investigated by the NTSC.
Kemenhub confirmed airworthy certificate has not issued standards for aircraft Sukhoi Superjet Indonesia 100. The reason for the Russian-made plane was not officially invited by the airline and will not be commercially operated in Indonesia.
"If there is demand, we will test, now it's still the stage of promotion," said the Head of Legal and Public Relations Directorate General of Civil Aviation Ministry of Transportation to detikFinance Ishaful Hayat, Thursday (10/05/2012)
On the one hand, PT Tri Marga Rekatama acknowledged that the route was at the request of the Sukhoi pilot himself. "That the request of the pilots. Among his pilots were also some of us, had memorized the route," said Sunaryo of PT Trimarga Rekatama, when contacted by AFP on Thursday (5/10/2012).
Thus, a route that would not necessarily be decided suddenly. The route had been discussed earlier. The pilot has also been coordinating with related parties.
Sunaryo also ensure Yablontsev Alexander, Pilot In Command (PIC) have known terrain of Mount Salak. "Oh, he knew because before he left, he studied the map of the route of flight," Sunaryo said in a news conference at the Halim Perdanakusumah air base, Jakarta, Thursday (10/05/2012).
Permission to 6 Thousand Foot Down
SSJ-100 planes are missing contact after 21 minutes take off from Halim Perdanakusumah Airport, at precisely 14:33 pm. When contact is lost, ATC at Soekarno-Hatta Cengkareng received a request from the pilot to descend from an altitude of 10 thousand feet to six thousand feet.
"New reports will drop it, not (allowed). Let NTSC investigating for it," said Bambang S Ervan when confirmed why the Air Traffic Control (ATC) permit the plane down to an altitude of six thousand feet.
Of Basarnas, PR Carey said the gallant Basarnas it is a pilot initiative. Not yet known whether the move was taken because of bad weather or other factors.When the pilot asked for permission, ATC has not given an answer.
"Have not answered, but have lost contact," he said.
PT Trimarga Rekatama representative said, Sukhoi would like to take the height of the fall in six thousand feet. But a question mark, the height of Mount Salak about seven thousand feet. What is not afraid of crashing?
"I also wonder why authorized," said Sunaryo of PT Trimarga Rekatama.
Mystery about whether the plane was allowed to drop or not to know. Again, NTSC duty to investigate.
Emergency signal not Detected
SSJ-100 planes are now lost contact, do not send an emergency signal, known as the Emergency Locator Transmitter (ELT), which directly emits a signal in an emergency.
The absence of an emergency signal is delivered by PR Basarnas, dashing Carey. Not only ATC Halim, Singapore and Australia but did not detect a signal that is usually used when the aircraft was no interference.
"There are no signals that we receive. Singapore and Australia also did not," said Head of Public Relations at Carey dashing Basarnas Halim Perdanakusumah Arrivals Terminal, Thursday (10/05/2012).
Proudly says, if the plane to crash, then the emergency signal is sent to the Air Traffic Control (ATC) nearby. In this case, usually Singapore and Australia are also able to detect.
"But is not there. For more details, we wait for the NTSC," he explained.
Though the specifications of the site Sukhoi aircraft, SSJ-100 is equipped with a failure detection system. Traffic Collision Avoidance features including System (TCAs), aka the second-generation system that can detect when the aircraft will experience a collision with another aircraft or object. SSJ 100 avionics systems have the advantage of flight safety and high reliability.
HP signal Still Burning
SSJ-100 was reported lost contact with ATC denan Cengkareng at 14:33 pm.However, HP's second cell phone aka Space magazine journalist, Yusuf and Dodi Aviantara Didi, was still active when contacted at 17.00 pm. But they did not pick up the phone.
"Yes, we have a check. Both are on the manifest," said Space magazine editor, Dudi Sudibyo, when contacted by AFP on Wednesday (09/05/2012).
Space Dudi said the party had tried many times to contact the journalist, but no answer from them. "Finally we have tried to contact us at 17.00 pm, tune into. But there's no answer," he explained.
Well, if the signal is still on HP also affect the flight?
Lock it all, there is the black box or black box that is located in the fuselage, whether caused by human error or weather factors? Black box is a pilot-ATC conversations recorded on the Cockpit Voice Recorder (CVR) and flight data in the Flight Data Recorder (FDR).
NTSC chairman Tatang Kurniadi said recorded conversation also has asked the pilot-ATC ATC held for investigative purposes. Of course, confidential records, can not be known to the public during an investigation conducted NTSC.
This is because once a case, data pilot-ATC conversation in the black box recordings in circulation in case of fall AdamAir KI 574 that crashed in Majene, West Sulawesi in 2008 before the NTSC release the results of its investigation.
The length is up to the NTSC investigation could eventually be opened to the public, berbilang months or even years. AdamAir KI 574 that crashed in the waters of Majene, West Sulawesi on January 1, 2007 can only be found the black boxes on August 28, 2007. The investigation was then announced in March 2008.
Merpati plane crash manifold MA-60 in Kaimana, Papua New released in May 2011 to May 2012 and the results. So, let's wait for the results of the investigation NTSC.
