Several Boeing 787-operated Air India flights cancelled on Tuesday amid DGCA-mandated enhanced technical checks
Various Boeing 787-operated flights of Air India were cancelled Tuesday as the enhanced safety inspections mandated by the Directorate General of Civil Aviation (DGCA) led to delays and non-availability of aircraft in most cases, according to sources in the know.
As per flight tracking data, at least nine Air India flights that were to be operated using the Boeing 787 aircraft have been cancelled so far on Tuesday. These include AI-143 (Delhi-Paris), AI-159 (Ahmedabad-London Gatwick), AI-915 (Delhi-Dubai), AI-153 (Delhi-Vienna), and AI-133 (Bengaluru-London). In most of these cases, as the flight from India was cancelled, it led to the cancellation of the return leg that was to be operated by the same aircraft. The number may rise further and in some cases, spill over to Wednesday.
Following the tragic crash of an Air India Boeing 787-8 aircraft in Ahmedabad on Thursday, the DGCA had directed the airline to carry out additional maintenance inspections on all 33 of its 787s. The aircraft was operating a flight between Ahmedabad and London Gatwick and had 242 people on board. All but one of those on board perished in the crash. There were several casualties on the ground as well.
The enhanced checks ordered by the DGCA include a one-time pre-departure check of aircraft systems and parameters including fuel parameters monitoring and associated system, cabin air compressor and associated systems, electronic engine control system, engine fuel-driven actuator and oil system, hydraulic system serviceability, and take-off parameters. Additionally, flight control inspection was to be introduced in transit inspection till further notice. Power assurance checks were also mandated.
On Saturday, Air India had announced that the checks were being performed, and informed passengers that some of these could 'lead to higher turnaround time and potential delays on certain long-haul routes, especially those to airports with operating curfews'.
On Tuesday, the carrier's Delhi-Paris flight (AI-143) was cancelled because the 'mandatory pre-flight checks identified an issue'. While the issue was 'being addressed', given that the Paris airport has a night curfew—restrictions on operations at night—the airline had to cancel the flight, Air India said. Consequently, the return flight AI-142 from Paris to Delhi was also cancelled.
On the cancellation of flight AI-159 from Ahmedabad to Gatwick, an Air India spokesperson said that it was cancelled 'due to the unavailability of the aircraft, resulting from airspace restrictions (in West Asia) and additional precautionary checks, leading to longer than usual turnaround of aircraft'. There was speculation that the flight was cancelled due to a technical snag with the aircraft, but Air India denied that. Consequently, flight AI-170 from London Gatwick to Amritsar was also cancelled as the same aircraft was to operate this flight.
Similarly, Delhi-Dubai flight (AI-915) and the return flight (AI-916) were cancelled, and so were the Bengaluru-London flight (AI-133) and its return leg (AI-132). In these cases, too, the aircraft that were to operate these flights were not available due to delays or being deployed on other sectors amid the fleet-wide enhanced checks, per sources. Air India's Delhi-Vienna flight (AI-153) was also cancelled.
In addition to these 787-operated flights, the airline's Mumbai-San Francisco flight (AI-179) — operated by a Boeing 777 aircraft — was also cancelled as the plane that had to operate the flight was unavailable due to technical issues. It had developed a snag during a technical halt at the Kolkata airport during its previous flight from San Francisco to Mumbai.

His parents were booked in the business class. He and his sister had premium economy seats.

We were finally airborne in a different aircraft at 5.40am on Tuesday and reached the city at 7.45am." TOI contacted a spokesperson of Air India and sent a query about the flyers' ordeal through a WhatsApp message. An official reply was awaited till going to press. An official of the airline said the flight got delayed because of a technical reason. A source in the airline said hotel accommodation and alternative flights were offered to the passengers.

Cabin crew said some checks were on." The flyer said, "After an hour, the pilot said there were some technical problems in the engine and a team of engineers would check these. The engineers took around 40-45 minutes to come. They said after 15 minutes the plane was ready for take-off, but it didn't move for another half-an-hour. We saw the ladder being attached to the aircraft door. Again the checks started. It was 12.30am by then." Rokade said, "There was no provision of any refreshments. The AC was being shut down frequently. Flyers lost cool and demanded they should be deboarded. After altercations, some passengers were made to exit the aircraft through the rear door.

After serving some refreshments, the airline's staffers told the passengers that the alternative aircraft needed some checks. The boarding time was revised to 4.30am and the boarding began at 4am. Rokade said, "When we were hoping that the plane would fly soon, some flyers said they won't travel on it citing safety concerns. The airline staffers had to let them go with their luggage.

"Travelling from Delhi to Pune on Air India flight AI2971. The flight is delayed by over 3 hours — no clear communication, no update, no assistance and very bad service.

They have been urgently asked to address the concerns of all affected passengers."

Rise in helicopter crashes may spur 15-30% hike in insurance premiums
Helicopter insurance premiums in India are likely to rise by 15–30 per cent owing to a recent spate of domestic accidents and mounting aviation losses faced by global reinsurers, industry insiders said. Aviation insurance is largely a reinsurance-driven area, with the general aviation market comprising corporate jets, helicopters and others accounting for 15 per cent of the segment in India. The remaining is commercial aviation. In FY25, the premium accumulated from the aviation segment in India was nearly ₹1,010 crore, up 4 per cent from the previous year. In general aviation, the premium rates are calculated based on the age and seating capacity of the hull combined with liability. The hull value of helicopters ranges from ₹25 crore to ₹30 crore going all the way up to ₹100 crore. The average premium in the helicopter segment is also around ₹75 lakh, according to industry experts. This is likely to increase by 25-30 per cent in line with the overall hardening in the aviation insurance market. 'There have been 5-6 helicopter crashes in the last few months. Overall, Indian insurers are under pressure in terms of premium versus claims. We have seen rates rising steeply for smaller rotor wing operators, like those who fly to Kedarnath, Chardham, or maybe small general aviation helicopter operators. In some cases, the premium has also doubled. Also, amid the Air India crash, there will be a hardening in the insurance market in the coming months,' an insurance broker said. On June 15, a helicopter crashed in Kedarnath, making it the fifth such incident in the Char Dham route, since the pilgrimage started on April 30. This comes days after the crash of Air India AI-171 in Ahmedabad. Previously, six people died when a helicopter crashed in Uttarkashi on May 8. Similarly, a crash was averted in Badrinath on May 12. On May 17, an air ambulance crashed in Kedarnath but no casualty was reported. On June 7, a helicopter on its way to Kedarnath made an emergency landing on the highway due to technical snag, developed during take-off. Additionally, rates in the aviation sector are also expected to increase due to huge claim outgo in the Air India crash combined with the ruling by the London High Court regarding jets stranded in Russia, among others. 'Helicopter insurance rates are expected to increase due to a combination of domestic accidents and significant global aviation losses. A series of high-profile claims, including a UK court ruling of $4.5 billion and other aviation incidents like the Air India and Boeing 737 MAX losses, are straining global reinsurers. Also, the overall aviation insurance premium rates are likely to harden due to limited capacity, heightened geopolitical risks and currency fluctuations. Premiums for helicopters may also rise 15–25 per cent, in-line with the overall aviation insurance segment,' an insurance executive said.

Air India cancels 7 flights in 24 hours, amid ongoing fallout from Ahmedabad plane crash
Air India Plane Crash: On 17 June 2025, Air India announced the cancellation of several key international flights, affecting passengers across various routes. Affected routes include Ahmedabad to London, Delhi to Paris, London to Amritsar, Mumbai-San Francisco, and more. DGCA also said on Tuesday that several AI flights were cancelled by Air India, of which five were Boeing 787 operated aircraft. The aviation watchdog also advised Air India to take measures to mitigate delays due to maintenance issues after the airline said latest cancellations and delays are due to technical faults & other factors . The Air India cancellations follow operational issues and precautionary measures mandated by MoCA after the recent Ahmedabad plane crash that killed 241 passengers and crew. Air India flight AI-159 from Ahmedabad to London Gatwick was cancelled due to the unavailability of the aircraft. The airline cited airspace restrictions and additional precautionary checks as reasons, emphasising that the cancellation was not due to any technical fault. This cancellation also led to the subsequent cancellation of flight AI-170 from London Gatwick to Amritsar on the same day. Following the Ahmedabad-London cancellation, the London Gatwick to Amritsar flight AI-170 was also cancelled on 17 June. This disruption impacted many passengers travelling between the UK and northern India. Air India's Delhi to Paris flight AI-143 was cancelled after mandatory pre-flight checks revealed a hydraulic issue. Due to night operation restrictions at Paris Charles de Gaulle Airport, the flight could not be delayed and was cancelled. Consequently, the return flight AI-142 from Paris to Delhi on 18 June was also cancelled. The airline is providing alternative arrangements and hotel accommodation to affected passengers. On 17 June 2025, Air India reportedly cancelled flight AI 915 from Delhi to Dubai amid ongoing operational disruptions following the recent Ahmedabad crash. This cancellation marks the sixth Boeing 787 Dreamliner flight grounded that day as the airline conducts rigorous post-crash safety checks. Official confirmation is awaited, but media reports indicate the aircraft developed technical issues during pre-flight inspections, prompting the cancellation. Similarly, flight AI 153 from Delhi to Vienna is believed to have been cancelled on the same day, though the airline has yet to officially confirm this. Like other affected flights, this cancellation is likely linked to precautionary measures and maintenance checks on the Dreamliner fleet. Air India also cancelled its Bengaluru to London and Mumbai to San Francisco flights on 17 June. The Air India Mumbai-San Francisco flight was terminated at Kolkata due to a suspected technical snag, prompting passengers to deplane and causing disruption at the airport. Air India's Bengaluru to London flight was cancelled on 17 June 2025, adding to the growing list of international flight disruptions faced by the airline in the wake of recent operational challenges. While detailed official reasons for this specific cancellation have not been extensively disclosed, it is understood to be part of the wider impact of technical and logistical issues affecting Air India's fleet, particularly involving Boeing 787-8 Dreamliners. Air India has offered full refunds to passengers affected by the cancellations on 17 June. The airline informed that travellers can request refunds through the airline's official website under the 'Manage Booking' section or by contacting Air India's reservation offices. Refunds will be credited to the original payment method, and the airline has assured passengers that cancellation charges will be waived given the exceptional circumstances.
