Brussels. August 12. INTERFAX.RU - In Brussels airport serious incident occurred - transport plane during take-off to drive out beyond the runway and collapsed into two parts, on Tuesday reported a representative aeroporta. Po him, four out of five people on board crashed plane victim , Received minor injuries.
Although aircraft fuel tanks were full, he did not fire. The reason for the disaster has not yet been determined.
Reportedly, the victim aircraft - Boeing-747 "in the cargo version - belonged to the American freight company" Kalitta "and sent to Bahrain.
The Belgium Accident Investigators of "Service public fédéral Mobilité et Transports" reported, that flight data and cockpit voice recorders have already been analyzed by the NTSB.
According to the data derived from the FDR, the airplane initially accelerated normally down runway 20 under a constant acceleration until a momentary loss of power by one engine, which was accompanied by an explosion witnessed both by the crew and air traffic controllers at the tower of Brussels. The loss of power and bang occurred at around V1 speed (maximum speed, at which decision to reject takeoff can be safely taken).
Two seconds after the bang all four engines were brought to idle and the airplane decelerated "vigorously", the slow down continuing until the final position 300 meters past the runway end. According to FDR thrust reverses were not used in the deceleration.
All four engines were inspected. All engines were running at the time of full stop, no catastrophic damage had occurred to either of the engines, no casings were punctured, all 4 engines remained attached to the wings. The outer engines (#1 and #4) turn freely, whereas the inner engines (#2 and #3) are blocked. All thrust reversers were found in the stowed position.
Especially engines #3 and #4, the right hand engines, were inspected with an endoscope, though very incomplete at this stage. The inspections however failed to reveal any damage, all compressor and turbine blades are in position and show no damage in both low pressure and high pressure compressors and turbines. The engines will be torn down in an appropriate workshop for further examination at the table under the presence of the Belgian AAIU.
The examination of the airframe and structures did not reveal any catastrophic damage prior to the final impact, when the airplane fell about 4 meters before coming to full stop just before the railway tracks. The airframe broke up in three parts upon that impact.
The cargo pallets did not move significantly. The cargo will be weighed to determine exact takeoff and stopping distance.
The investation team is also interviewing first responders like fire fighters and policemen. The Belgian AAIU expects, that the investigation will last 6 to 12 months before a final report will become available.
The airport reopened the runway by June 13th, however initially without ILS. Several antennas of the instrument landing system for runway 20 as well as approach lighting for runway 02 have been destroyed by the impact of the Kalitta Boeing 747, the repairs are estimated to take eight to twelve weeks including calibration.
One pilot reported in interviews with the Belgian Accident Investigators, that he heard a muffled noise followed by another muffled noise, then the airplane went off the runway. The crew managed to bring the airplane back onto the runway but could not stop the airplane before the end of the runway, Belgian news media report.
The fuel has been pumped off the airplane on Tuesday, the site has been declared safe Wednesday.
No damage on the surface of the runway was found, possible damages to runway and approach lightings as well as the ILS are yet to be evaluated. The runway is thought to be reopened within 5 to 8 days.
The chief of Belgocontrol, responsible for Air Traffic Control at Brussels Airport, said, that one of the controllers on duty saw a flame out of a starboard (right hand) engine. The observation was immediately relayed to the crew and the fire brigades activated at the same time.
A Kalitta Airways B747-200, registration N704CK performing freight flight K4-207 from Brussels to Bahrain with 5 crew, overran runway 20 at Brussels Zaventem Airport while rejecting takeoff. The fuselage broke up in three parts, but no fire erupted. 4 minor injuries are being reported.
A witness ("plane spotter") reported to have heard some "slight knock" while the airplane attempted takeoff, then saw the plane coming towards him and started to run for cover.
Runways 02/20 and 07R/25L were closed. The railway lines to and from the airport were shut down as a precaution as the airplane came to rest close, but before the railway lines with fuel spilling. Fire brigades stopped the fuel spillage in the meantime. As of Monday morning (May 26th) the train traffic is gradually resuming. Runway 07R/25L has been reopened while runway 02/20 is still closed.
The Belgian TV reported in their Sunday evening news edition, that the airplane carried diplomatic cargo including a diplomatic car plus additional cargo, described by Belgian Authorities as not dangerous for environment or people. The airplane carried 77 tons of cargo, about half of which was the diplomatic cargo. Police has been deployed to protect the airplane and cargo.
DHL have confirmed, that they had leased the airplane to carry DHL cargo from Brussels to Bahrain. A spokeswoman for DHL said, that they are not sure whether items to be delivered, which include post, will be affected.
The National Transportation Safety Board of the USA (NTSB), led by NTSB investigator Joe Sedor, is going to join the Belgian Government for the investigation. The NTSB reports in the press release, that a loud bang was reported during the takeoff, continuing, that there were 4 people on board of the airplane with no injuries being reported.
