India’s aviation regulator has mandated inspections of all Boeing 787 aircraft operated by local airlines following an Air India crash that killed 270 people, Aviation Minister Ram Mohan Naidu announced on Saturday.

The Directorate General of Civil Aviation (DGCA) is investigating all possible causes of the disaster.

On Friday, the DGCA ordered Air India to perform additional maintenance checks on its Boeing 787-8 and 787-9 aircraft with GEnx engines, including take-off parameter assessments, electronic engine control tests, and fuel system checks.

“We’ve also ordered enhanced surveillance of the 34 Boeing 787s in India’s fleet,” Naidu said in New Delhi. “Eight have been inspected, and all will be completed urgently.”

It remains unclear if government officials will oversee the inspections.

The Air India Boeing 787-8 Dreamliner, carrying 242 passengers and crew to Gatwick Airport, crashed seconds after take-off on Thursday, striking buildings and erupting into a fireball.

It is the deadliest aviation disaster in a decade.

Only one person survived, while the plane hit a medical college hostel, killing others on the ground.

At least 270 bodies have been recovered, according to Dhaval Gameti, president of the Junior Doctors Association at BJ Medical College.

Air India, operating 33 Boeing 787s, is conducting the mandated safety checks, which may cause delays on long-haul routes.

IndiGo, with one Boeing 787, did not comment.

While the aircraft are not grounded, a source indicated the government is considering this option. Investigations are examining engine thrust, flaps, and landing gear issues.

The crash has intensified scrutiny on Air India, which has been working to restore its reputation since its 2022 acquisition by the Tata Group.

Tata’s chairman emphasised the need to understand the incident’s cause.

Naidu said a government panel will deliver a report within three months, pledging to implement safety improvements based on its findings.
