Ahmedabad plane crash: Engines lost power at critical stage, says ex-Air Force chief Arup Raha
Kolkata, Former Chief of Air Staff, Air Chief Marshal Arup Raha , on Saturday said the engine of the Air India aircraft that crashed near Ahmedabad airport on June 12 "definitely" lost power at a critical stage and there was no time for recovery.
He said there could be many other possibilities for the crash such as fuel contamination, and glitches in software and control systems.
Rejecting the sabotage angle as raised by some quarters, Raha urged all not to speculate things and wait for the Directorate General of Civil Aviation to complete the investigation.
The Ahmedabad-London flight crashed into buildings on a medical college campus shortly after taking off from Sardar Vallabhbhai Airport on Thursday, killing 241 out of 242 persons on board as well as several others on the ground.
"This is very sad, heartbreaking. So many people died together. As of now, it is very difficult to say what has gone wrong," Raha told reporters on the sidelines of an ICC event on the role of MSME in the defence sector.
"Definitely there was loss of power and at a critical stage... you are transmitting from the ground into the air, your height is little. There is no time for recovery. And loss of engine power will result in a stall... will then descend very rapidly and crash. And that is what has happened," he said.
The former Air Force officer said engines of the Boeing 787-8 Dreamliner generate thrust and losing the power of both engines simultaneously is very rare - "may be one in a billion cases".
It is difficult to say what went wrong, he said and talked about other possibilities.
"There might be a software issue, some problem in the control , fuel contamination... But I do not give any credence to the sabotage angle. The loss of power was an indication of some glitch," Raha said.
"We should not make any wild claims till the DGCA and other agencies of the government complete the probe," he said.
Asked about the role of the ground staff, he said they have to certify the weight an aircraft has carried.
"Based on these inputs on the ground, the pilot takes off. You can't add several kgs to the stipulated figures. But as I said investigations will unravel the reason and factors," Raha said.
He said he does not think bird hit could be the reason behind the crash of the Boeing 787-8 aircraft.
"There were complaints whistleblowers from their own company. I think those need to be investigated," Raha said.
Earlier, addressing the ICC event, he advocated the manufacturing of aircraft engines indigenously.

Crashed Air India Aircraft's Comprehensive Check Was Due In December 2025: Officials
Last Updated: The plane en route to London Gatwick Airport crashed into residential quarters of BJ Medical College in Ahmedabad. Over 265 people have lost their lives in the tragic incident. Ahmedabad Plane Crash: Air India's ill-fated Boeing 787-8 Dreamliner that crashed minutes after take off from Ahmedabad's Sardar Vallabhbhai Patel International Airport on June 12 underwent comprehensive maintenance checks in June 2023 and was due for the next scheduled comprehensive checks in December this year, according to airline officials. The plane en route to London's Gatwick Airport crashed into the residential quarters of BJ Medical College in Ahmedabad. Over 265 people have lost their lives in the tragic incident. The aircraft VT-ANB underwent C checks or comprehensive checks in June 2023 and the next such scheduled checks were to happen in December this year, reported news agency PTI citing the airline officials. The C checks were done by AIESL (AI Engineering Services Ltd). Additionally, the right side engine of the aircraft was overhauled and installed in March 2025, while an inspection of the left side engine was done as per the engine manufacturer's protocol in April 2025, the officials said. The aircraft was powered by GEnx engines, manufactured by GE Aerospace. The officials also claimed that there were no issues with the engines or the aircraft. However, there was no official statement from Air India. After the incident, aviation watchdog DGCA on Friday ordered enhanced safety checks of Air India's Boeing 787-8/9 planes. The airline on Saturday said that the one-time safety checks of the aircraft are on track and the checks have been completed for nine planes. The airline has 26 legacy Boeing 787-8s and seven Boeing 787-9s in its fleet. On Friday, GE Aerospace said it supports the action being taken by the Directorate General of Civil Aviation (DGCA) for enhanced safety inspections of the Air India 787-8/9 fleet. "We continue to work closely with the appropriate regulatory and investigative agencies, and we are committed to providing all technical support necessary to understand the cause of this accident," a GE Aerospace spokesperson had said in a statement. The Aircraft Accident Investigation Bureau (AAIB) is probing the crash and a high-level multi-disciplinary committee has also been set up to examine the causes for the accident.

How passenger in seat 11A became only survivor of Air India plane crash
Viswash Kumar Ramesh was one of 242 people on the 787-8 Dreamliner that went down shortly after takeoff in Ahmedabad, India. Somehow, he walked away. Only the passenger in Seat 11A on Air India Flight 171 lived to tell the tale, a survival nothing short of a miracle. When the Air India plane with 242 people onboard crashed into a building moments after taking off from the international airport in Ahmedabad, it burst into flames. The impact, heat and smoke were so intense, officials said, that escape was impossible. Except for Viswash Kumar Ramesh, 38. Mr. Ramesh's story initially appeared too good to be true; the crash was so severe that the bodies of most victims were charred beyond recognition, officials said. But by late evening, Air India confirmed that there had been one survivor, who was getting treatment at the hospital. Amit Shah, India's home minister, said he had visited the survivor, and Indian media ran photos of Mr. Shah standing at Mr. Ramesh's bedside. 'I still can't believe how I got out alive,' Mr. Ramesh said on Friday in an interview from his hospital bed with India's state broadcaster, Doordarshan. 'I thought I was also about to die.' Mr. Ramesh, who was seated in an exit row, said the plane had felt 'stuck five or 10 seconds after takeoff,' and it seemed to be trying to accelerate when it crashed. The front of the plane, after hitting buildings, crashed into an open area, he said, while the tail was stuck in a building, which was later identified as the dining facility of a medical college. Mr. Ramesh said he unbuckled his seatbelt after the crash when he saw a chance for escape. He did not make clear whether he had to open the emergency exit he was sitting next to, or if the impact had caused it to open. 'When my door broke, I saw there was some space — that I could try to get out,' he said in the interview. 'The other side, people couldn't get out, as it was crushed against a wall.' Mr. Ramesh, who is a British citizen, was returning to England after vacationing in India along with his brother Ajay, their younger brother Nayan said. Ajay, who the passenger list showed was seated in 11J on the right side of the plane, did not survive. Shortly after the crash, Mr. Ramesh made a video call from near the wreckage to his family in Leicester to confirm he was safe, the younger brother said. There, the family home was a scene of both mourning for Ajay and stunned amazement that Viswash had somehow walked away.

DGCA curbs Char Dham chopper flights post-crash, steps up surveillance
The Directorate General of Civil Aviation (DGCA) on Sunday said it has already reduced the frequency of helicopter operations to Char Dham in Uttarakhand and is carrying out enhanced surveillance amid a spate of recent incidents during the pilgrimage season. The regulator's statement came after an Aryan Aviation Bell 407 helicopter crashed earlier in the day while flying from Kedarnath to Guptkashi. The helicopter went down near Gaurikund shortly after takeoff, killing five passengers, an infant, and the pilot. #WATCH | Rudraprayag, Uttarakhand: Today, a helicopter operating a flight on the sector Shri Kedarnath to Guptkashi was involved in an accident. A total of 07 people were on board this helicopter, who died on the spot. Rescue teams were immediately dispatched under the direction… — ANI (@ANI) June 15, 2025 Fifth accident in five weeks Sunday's crash marks the fifth helicopter-related incident in the Char Dham region in just over a month, raising urgent questions about operational discipline and safety compliance in difficult terrain. It also follows the tragic crash of an Air India Boeing 787 aircraft near Ahmedabad that killed over 265 people. 'As a precautionary measure, DGCA has already reduced frequency of helicopter operations to Char Dham, is carrying out the enhanced surveillance and reviewing the operation for any further action,' the regulator said in its statement. Recent incidents raise alarm On June 7, a private AW119 helicopter crash-landed shortly after takeoff from Sirsi. The pilot managed to land safely on a road near Badasu village, and there were no injuries. Earlier, on May 17, an Aiims-Rishikesh-operated heli-ambulance suffered tail damage during an attempted landing at Kedarnath. The pilot, doctor, and nurse onboard were unharmed despite the aircraft being damaged. On May 12, a helicopter's rotor blade struck a vehicle at the Badrinath helipad, sparking protests from local priests. No casualties were reported. The most serious of the earlier incidents occurred on May 8, when a helicopter en route to Gangotri crashed near Gangnani in Uttarkashi. Five pilgrims and the pilot were killed, while one person survived with critical injuries. Surveillance and operator suspensions In a separate statement issued on June 9, the DGCA said the spate of occurrences 'underscored the necessity for further strengthening the safety oversight' of Char Dham operations. It said investigations were underway into each incident to determine causes ranging from mechanical failures to weather conditions. 'DGCA has a zero-tolerance policy for safety violations,' the regulator reiterated in the June 9 communication. It added that 'special audits/enhanced surveillance' of operators had been ordered and that operations would be curtailed if needed. The DGCA is also monitoring live camera feeds from Kedarnath provided by the Uttarakhand Civil Aviation Development Authority (UCADA). In early June, it suspended two helicopter operators for failing to comply with parking protocols. Another charter operator had been suspended in May for safety violations. OGE-only flights mandated All operators flying to Char Dham have now been instructed to operate only under out-of-ground-effect (OGE) conditions until further notice. Operating in OGE conditions means helicopters must fly and hover at altitudes where they do not benefit from the additional lift generated near the ground. This standard is crucial for safety in mountainous and high-altitude terrains like Char Dham.
