Air India flight AI 171 flew at 1.38 pm on June 12 and the accident occurred at 1.40 pm. At that time the plane was at an altitude of 200 feet.
It will take some time to get the correct details of the reasons for the Ahmedabad aircraft accident. Meanwhile, the New York Times (NYT) has analyzed photos, videos and audio of the accident. The Analysis indicated that the takeoff was normal.
According to NYT, the destruction began in the air. Prior to the takeoff, the aircraft opened wing flap and slats, flying from General Point using the entire length of the runway. A few seconds of the flight, the landing gear could not be completely closed.
The flight AI 171 from Ahmedabad to London collided with a medical hostel building shortly after the 171 takeoff. It killed 270 people, including 241 passengers and crew members. Only one passenger is left alive in this accident.
What are the indications in the investigation of NYT on four aspects …
1. Takeoff: AI 171 had flew from the point from which the last seven takeoffs were also done from the same place.
- The takeoff of AI 171 was under investigation after the accident. The question was- whether there were any prior warning signs during the takeoff.
- Many experts involved in the panel said- takeoff was normal. It was not felt that the aircraft was not getting the necessary thrust from the engine on the ground.
- CCTV footage and flight data analysis suggests that the aircraft had flew seven times before the point from which the aircraft left the runway.
- NYT set a possible position of CCTV and estimated the takeoff point.
- According to flight tracking data, the aircraft was taxi next to the runway at 1:34 pm. 5 minutes later, at 1:39, the aircraft was in the air near the end of the runway. When the aircraft comes in the frame at 1:38 pm, the situation was possible only when it has done a box.
- The initial direction in the air of the aircraft is somewhat normal. Flight data shows that it was no different from the last 7 flights of AI 171. Former pilot John Cox says, “When the aircraft came into the air, the initial climbing rate looked quite normal”.
2. Slats, Flaps: Both were in spreading positions, ie pilots adopted some standard procedures at the beginning of takeoff.
- Falling of the aircraft immediately after takeoff increased the concern as to whether there were extended to slats and flaps takeoff on its wings. These are usually opened before the flight, so that the surface area for the lift increases.
- Slats on the right wing in a picture of debris are seen in an expanded position. This indicates that they were probably activated before takeoff.
- The crash video shot from the roof shows a slight shade on the front part of the right wing of the aircraft. This indicates that slats were probably extended.
- Some experts say that it is certainly difficult to say anything on the situation of slats based on the quality of the video. Nevertheless, this is another evidence that the pilots completed some standard procedures at the beginning of the takeoff.
Sean Praniki, who was an accident investigator at the airline Pilots Association, says that the slats were either extended before the impact or at the time of explosion on the ground. Flaps located on the rear edges of the wings were also deployed, even though the video is not clearly visible. The slats automatically expand on the Boeing 787-8 aircraft when pilot flaps.
3. Landing gear (the first sign of the problem): The process of covering them with the cockpit started, but it could not be fulfilled …
- The video analysis received the first indication of trouble immediately after takeoff. It was- Landing gear does not go back completely inside the aircraft.
- Pilots draw landing gear after takeoff. The aircraft can also fly with open landing gear, but pilot pulls the drag.
- In the video, the landing gear truck appears in front wheel down position after takeoff. It is an indication that the process of covering the landing gear from the cockpit began, but it stopped in the middle.
- John Goglia, former member of the National Transportation Safety Board, says, it is necessary to be in the correct position, so that it can fit properly in the aircraft. The pilots seem to have started the process of shutting down the landing gear, but could not complete. Perhaps due to electricity failure. This affected hydraulic power.
Emergency power generator was active
- The optional power source comes out of the lower part of the aircraft when the Boeing 787-8 Dreamliner fails electricity, hydropholic or engine power failure. This is called RAM Air Turbine. It gives power worth help in emergency landing.
- Aviation experts described the specific sound heard in the crash video as evidence of emergency power generator active. According to forensic audio analysis, the sound of the crashed aircraft matches more than 97% of the example in which the emergency turbine was active.
4. Jerk (this very unusual thing): The aircraft did not show a shock or side movement, that is, the two engines were spoiled simultaneously …
- There are indications that the engine failed after the takeoff. Often when an engine fails, the aircraft bends or performs side movement. The pilot or aircraft system fixes it. Both videos did not show anything like this.
- Former FAA investigator Jeff Gazetti says, “There is no indication of an asymmetric thrust. Do not, radar deflection. The engine does not smoke or fire. That is, there was a semetrical loss of power. It is an indication that both engines deteriorated simultaneously. This is a very unusual situation.
- The reasons for the engine failure may cause problems like contaminated fuel source, wrong input of flight parameters before takeoff.
Former Gujarat Chief Minister Vijay Rupani also died in the plane crash
Air India flight number AI 171 was going from Ahmedabad to London. It had a total of 230 passengers, including 169 Indians, 53 British, 7 Portuguese and one Canadian citizen. These include 103 men, 114 females, 11 children and 2 newborns. The remaining 12 were crew members. Former Gujarat Chief Minister Vijay Rupani also died in the accident.
251 dead who lost their lives in the Ahmedabad plane accident have been identified with DNA. The bodies of 245 dead have been handed over to their families.
Pilot made a medium call
According to FutureDar 24, the last signal of the aircraft was found at an altitude of 190 meters (625 ft), which came immediately after the flying. India’s Civil Aviation Regulator DGCA reported that the aircraft flew from runway 23 at 1:39 pm on June 12. After flying, the pilot of the aircraft sent a medium call (emergency message) to the air traffic controller, but after that no response was received.
According to DGCA, there were a total of 242 people in the aircraft, including two pilots and 10 cabin crew. The pilot had an experience of 8,200 hours and the co-pilot had 1,100 hours of flight experience.
