Air India Moves Aircraft Maintenance In-House After Safety Concerns
Air India shifts aircraft maintenance in-house with Singapore Airlines’ support following safety lapses and fatal crash, aiming for fleet expansion and improved standards.
Air India’s Strategic Pivot: Moving Aircraft Maintenance In-House Following Fatal Crash and Safety Concerns
The Tata Group-owned Air India is embarking on a major operational transformation by shifting critical aircraft maintenance services from the government-owned Air India Engineering Services Limited (AIESL) to in-house operations, with support from strategic partner Singapore Airlines. This move, accelerated by the tragic crash of Flight AI-171 in June 2025, which resulted in 241 fatalities, marks a fundamental change in how India’s flagship carrier approaches aviation safety and maintenance standards. The shift follows regulatory audits that uncovered over 50 safety lapses in Air India’s operations, highlighting systemic issues in maintenance protocols and operational procedures.
Singapore Airlines, which acquired a 25.1% stake in Air India after the Air India-Vistara merger in November 2024, will provide technical expertise to help Air India build robust internal maintenance capabilities. This is particularly important as Air India prepares for a massive fleet expansion to 570 aircraft. The transformation is not just a reaction to immediate safety concerns but also a strategic repositioning to support Air India’s growth ambitions in one of the world’s fastest-growing aviation markets, where fleet sizes and operational complexity are reaching unprecedented levels.
This article explores the sequence of events leading to this strategic shift, the technical and operational challenges revealed by recent audits and accidents, and the broader implications for India’s aviation industry and Air India’s future trajectory.
Background and Historical Context of Air India’s Transformation
Air India’s journey from a government-owned carrier to a privately-managed airline under the Tata Group is one of the most significant transformations in Indian aviation history. The Tata Group acquired Air India in 2021, marking a return to its original founders after more than fifty years of government ownership. This acquisition was part of a broader government strategy to divest from loss-making public sector enterprises and allow private management to revitalize struggling assets.
Since the acquisition, Air India has undergone comprehensive changes: fleet modernization, route expansion, service improvements, and operational restructuring. The merger with Vistara in November 2024 allowed Singapore Airlines to acquire a 25.1% stake in the enlarged Air India entity, bringing valuable international expertise to the table. This partnership is vital as Air India announced one of the largest aircraft orders in aviation history in February 2023, committing to 470 aircraft from Boeing and Airbus, valued at over $40 billion.
Historically, Air India relied on AIESL for maintenance, repair, and overhaul (MRO) services. AIESL, a government-owned subsidiary, provided maintenance to Air India and other international carriers at major Indian airports. However, as Air India modernized, concerns grew about AIESL’s service quality, efficiency, and alignment with the airline’s new objectives. Even before the recent crash, Air India’s management had identified the need for greater control over maintenance operations, though immediate operational improvements were initially prioritized.
The AI-171 Crash: A Catalyst for Change
The crash of Air India Flight AI-171 on June 12, 2025, was a defining moment that forced Air India to reconsider its maintenance outsourcing model. The Boeing 787 Dreamliner crashed shortly after takeoff from Ahmedabad, killing all but one of the 242 people on board. The sole survivor, Vishwash Kumar Ramesh, escaped with minor injuries after his section of the aircraft detached and landed on the ground floor of a medical college hostel.
Investigations revealed that the aircraft’s fuel control switches had unexpectedly moved from ‘run’ to ‘cutoff’ just seconds after takeoff, cutting off fuel to both engines. Cockpit voice recordings captured confusion among pilots about the fuel cutoff. This technical anomaly raised concerns about potential systemic issues with Boeing 787 aircraft and maintenance protocols, especially as similar incidents had been reported previously on other carriers.
The crash prompted major carriers like Etihad Airways and Singapore Airlines to inspect their Boeing 787 fleets and review maintenance procedures. The event underscored the need for robust maintenance protocols and highlighted vulnerabilities in Air India’s existing systems, particularly those managed by AIESL.
“The preliminary investigation found that the aircraft’s fuel control switches had unexpectedly moved from ‘run’ to ‘cutoff’ just seconds after takeoff, raising serious questions about maintenance protocols and system reliability.”
Comprehensive Safety Audit Reveals Systemic Issues
Following the crash, India’s Directorate General of Civil Aviation (DGCA) conducted a comprehensive safety audit that revealed 51 safety violations across Air India’s operations, the highest among Indian airlines. These were categorized into Level 1 (serious) and Level 2 (less urgent) breaches, with Level 1 issues requiring immediate corrective action.
The audit identified significant training gaps for Boeing 787 and 777 pilots, incomplete simulator training, and deficiencies in crew rostering and duty time management. For example, at least four international flights operated with insufficient cabin crew, and one flight exceeded duty time limits by over two hours. The audit also found no chief pilots assigned for the Airbus A320 and A350 fleets, and inconsistencies in pre-flight safety protocols.
Compared to other airlines, Air India’s audit results were concerning. IndiGo, with a larger fleet, recorded only 23 findings, while Air India Express and Vistara, both under the Air India Group, also had notable lapses. The audit highlighted the need for a fundamental overhaul of Air India’s safety management and maintenance oversight.
The Shift from AIESL to In-House Maintenance
AIESL, as a government-owned entity, has been the backbone of Air India’s maintenance services. However, its performance has come under scrutiny, especially as Air India pursues modernization and rapid fleet expansion. In the financial year 2022-23, AIESL handled around 450 aircraft and generated revenues of Rs. 2,029.86 crores (about $244 million), but its net profit declined by 24% year-over-year, raising questions about its capacity to invest in modernization.
Operational issues, such as delayed repairs, aircraft cleanliness, and turnaround efficiency, have been cited as ongoing concerns. As Air India prepares to induct advanced aircraft like the Boeing 787, 777X, and Airbus A350, the need for specialized maintenance expertise becomes even more pressing. The Indian MRO market, while growing, still relies on imports for over 90% of its requirements, creating cost and supply chain vulnerabilities.
Recognizing these challenges, Air India is moving to bring key maintenance functions in-house, starting with pre-flight inspections, daily checks, and minor repairs. This phased approach allows Air India to build internal capabilities while continuing to rely on AIESL for more complex tasks during the transition. The goal is to achieve greater control over maintenance quality, scheduling, and costs, critical factors as the airline expands its fleet and operations.
Singapore Airlines’ Role and Technical Expertise
Singapore Airlines’ involvement is central to Air India’s maintenance transformation. With a 25.1% equity stake following the Vistara merger, Singapore Airlines has a vested interest in Air India’s operational success. Its subsidiary, SIA Engineering Company (SIAEC), is Asia’s leading MRO provider, servicing more than 60 airlines and maintaining advanced aircraft like the Boeing 787 and Airbus A350.
SIAEC’s expertise is particularly valuable for Air India’s diverse and expanding fleet. Their experience maintaining similar aircraft types, combined with advanced diagnostic and predictive maintenance technologies, positions Air India to rapidly upgrade its internal capabilities. The partnership also leverages historical ties, Air India assisted Singapore Airlines in the 1970s, and now the roles are reversed.
Beyond technical support, Singapore Airlines brings best practices in safety culture, regulatory compliance, and operational excellence. This collaboration is expected to facilitate knowledge transfer, joint procurement, and shared facilities, resulting in cost efficiencies and improved service standards for Air India.
“Singapore Airlines’ technical expertise and global best practices in maintenance are expected to accelerate Air India’s progress toward operational excellence and safety culture transformation.”
Financial and Strategic Implications
Transitioning to in-house maintenance requires significant upfront investments in facilities, equipment, technology, and workforce training. Modern maintenance facilities, especially for widebody aircraft, involve substantial capital expenditure. Air India’s shareholders, Tata Sons and Singapore Airlines, have committed over $1.15 billion in the 2024-25 financial year to support these initiatives.
While the initial costs are high, long-term benefits include improved cost control, operational efficiency, and the potential to generate revenue by offering MRO services to third parties. Airlines typically achieve 15-25% cost savings by internalizing maintenance, primarily through reduced markups and better scheduling. For Air India, with annual maintenance costs estimated in the hundreds of millions, these savings are substantial.
Developing internal maintenance capabilities also supports India’s goal of building a robust domestic MRO industry, reducing reliance on foreign providers and strengthening supply chain resilience. This is especially important as the Indian aviation market is projected to quadruple in fleet size over the next two decades, with demand for 2,835 new aircraft by 2043 according to Boeing’s Commercial Market Outlook.
Conclusion
Air India’s decision to transition aircraft maintenance from AIESL to in-house operations, supported by Singapore Airlines, marks a pivotal moment in the airline’s transformation. The move addresses immediate safety concerns highlighted by the AI-171 crash and DGCA audits, while positioning Air India for sustainable growth and operational excellence in a rapidly evolving market.
By investing in internal capabilities, leveraging global best practices, and building a culture of safety and compliance, Air India aims to restore its reputation and compete effectively with both domestic and international carriers. The success of this transition will depend on effective execution, ongoing investment, and a continued commitment to safety and quality as the airline expands its fleet and network.

FAA Announces $481 Million Airport Infrastructure Grants
The FAA distributed 191 grants totaling $481M across 36 states to modernize runways, taxiways, and terminals.
The Federal Aviation Administration (FAA) announced a $481 million infrastructure funding package on September 3, 2026, distributing 191 grants across 36 states and two U.S. territories to modernize runways, taxiways, and passenger terminals.
The Airport Infrastructure Grants (AIG) program allocations, announced by U.S. Transportation Secretary Sean P. Duffy and FAA Administrator Bryan Bedford, are timed ahead of the Labor Day travel period. The funding targets both major commercial hubs and general aviation facilities to accommodate increasing passenger volumes and enhance operational safety.
Targeting high-volume and regional infrastructure
Hartsfield-Jackson Atlanta International Airport (ATL) secured the largest single allocation, receiving $100 million. The FAA stated these funds will support runway, taxiway, and terminal reconstruction, alongside improvements to the runway safety area.
San Diego International Airport (SAN) received $30.3 million for terminal construction, while Louisville Muhammad Ali International Airport (SDF) was awarded $32.5 million for terminal reconstruction. Milwaukee Mitchell International Airport (MKE) secured $14.2 million for taxiway construction and rehabilitation, and El Paso International Airport (ELP) received $8.7 million to rehabilitate its apron.
General aviation also received targeted funding, including a combined $2.5 million for airports in Wisconsin to rebuild terminals, rehabilitate runways and taxiways, and reconstruct snow-removal-equipment buildings.
“From our regional hubs to some of America’s busiest airports, we are investing in critical infrastructure that will provide American families with a more seamless, efficient travel experience for years to come,” Duffy said in the press release.
Bedford added that the grants are designed to help airports meet current traveler demands while preparing for future capacity requirements.
Modernization efforts amid workforce tensions
The infrastructure grants follow another recent FAA milestone. On September 1, 2026, Duffy announced the agency had installed its 100th Surface Awareness Initiative (SAI) system. This deployment reaches nearly half of the 220 airports scheduled to receive the aircraft and vehicle surveillance technology, which is designed to reduce runway incursions.
While the agency highlights infrastructure and technology investments, FAA leadership faces concurrent pressure regarding workforce compensation. On September 4, 2026, U.S. Senators Tammy Duckworth (D-IL) and Dick Durbin (D-IL) issued a public letter demanding Bedford release a congressionally approved pay raise for air traffic controllers.
The senators allege Bedford has withheld a 2.8 percent portion of a 3.8 percent pay increase for four months to leverage workforce utilization.
AirPro News analysis
We note a distinct contrast between the FAA’s well-publicized capital expenditures and its ongoing labor management challenges. The $481 million AIG distribution and the SAI rollout demonstrate steady progress on the hardware and concrete side of the National Airspace System. However, the public intervention by Senators Duckworth and Durbin highlights a persistent friction point regarding the human capital required to operate that infrastructure. Upgraded taxiways and new terminals at facilities like ATL and SAN will yield limited capacity improvements if the air traffic control workforce remains strained by compensation disputes and staffing shortages.

NTSB Releases Preliminary Report on Carlisle Airport Midair Collision
NTSB preliminary report details a fatal midair collision between a Cessna 150H and a PA State Police helicopter at Carlisle Airport.
This is a developing story. Information may change as official details are released.
This is original reporting and analysis by AirPro News.
The National Transportation Safety Board (NTSB) has released its preliminary report on an August 19, 2026, midair collision at Carlisle Airports (N94) in Pennsylvania that resulted in the death of a civilian pilot and injuries to two state troopers. The collision involved a Cessna 150H and a hovering Pennsylvania State Police (PSP) Bell 407GX Helicopters during mixed-aircraft operations at the non-towered airfield.
Released on September 2, 2026, the preliminary investigation record outlines the sequence of events leading up to the 6:52 p.m. local time collision. The NTSB report confirms that both aircraft were in communication via the Common Traffic Advisory Frequency (CTAF) prior to the event. The exact cause of the collision remains under Investigation by the NTSB and the Federal Aviation Administration (FAA).
Flight path and collision sequence
According to the NTSB preliminary report and statements from the PSP, the Bell 407GX helicopter was conducting a training exercise. The helicopter crossed the runway threshold at an altitude of 50 feet before descending into a hover taxi. At the same time, the Cessna 150H was approaching the airport to land.
Radio communications detailed in the report indicate that the helicopter crew instructed the Cessna pilot to extend his downwind leg. The Cessna pilot acknowledged the instruction, stating his intention to land after the helicopter. However, as the helicopter hovered off the runway, the Cessna veered off its intended landing path to the north side of the runway. The fixed-wing aircraft subsequently collided with the rear of the hovering helicopter, striking its tail and main rotors.
Casualties and ongoing investigation
The collision resulted in one confirmed fatality. The pilot of the Cessna 150H, identified by his employer Penn State Health as 57-year-old Dr. Paul William Sokoloski, sustained fatal injuries. The two occupants of the PSP helicopter, identified as Corporal Bryce Corman and Trooper Jason Mills, sustained injuries in the collision.
NTSB aviation Accident investigator Aaron McCarter is leading the inquiry. While surveillance video captured the collision, the NTSB has not yet determined why the Cessna deviated from its landing path. A final report detailing the probable cause is not expected for several months.
AirPro News analysis
We note that mixed-aircraft operations at non-towered airports inherently require precise communication and situational awareness, particularly when fixed-wing aircraft and rotorcraft share the same traffic pattern. While some aviation commentators have speculated that rotor wash or wake turbulence from the hovering Bell 407GX may have contributed to the Cessna 150H veering off course, this remains entirely unverified. The NTSB has explicitly stated that it is too early to attribute the Cessna’s flight path deviation to any specific factor. Investigators will likely examine environmental conditions, aircraft performance data, and pilot actions as they work toward a final probable cause determination.

NTSB: Thermal Plugs Caused AA Flight 3023 Tire Failure
NTSB determines melted thermal relief plugs caused tire failure on American Airlines 737-8 at Denver, triggering emergency evacuation.
The National Transportation Safety Board (NTSB) has determined that melted thermal relief plugs caused the left main landing gear tires to fail on an American Airlines Boeing 737-8 during a July 2025 takeoff roll at Denver International Airport (DEN), prompting a high-speed rejected takeoff and emergency evacuation.
The final aviation investigation report, published on August 26, 2026, officially closes the inquiry into American Airlines Flight 3023. The document details the mechanical sequence that led to the tire failure while highlighting significant passenger noncompliance during the subsequent evacuation, as travelers ignored crew commands and retrieved carry-on baggage.
Mechanical sequence and rejected takeoff
The incident occurred on July 26, 2025, involving a Boeing 737-8, registration N306SW, equipped with CFM International LEAP-1B28 engines. According to the NTSB, the flight experienced an approximate 25-minute delay while awaiting departure at runway 34L.
During the subsequent takeoff roll, as the aircraft reached an indicated airspeed between 90 and 100 knots, the captain reported hearing a loud pop accompanied by a noticeable bump. The flight crew initiated a rejected takeoff at speeds above 80 knots.
The NTSB determined the probable cause of the incident was the melting of thermal relief plugs in the left main landing gear. This melting released tire pressure and caused the tires and wheels to fail during the takeoff roll. The agency noted that this failure resulted in abnormal airplane handling characteristics, which prompted the flight crew to reject the takeoff. Debris from the fractured wheels caused minor damage to the aircraft, including a three-inch dent on the lower skin of the left wing.
Emergency evacuation and passenger behavior
Following the rejected takeoff, the flight crew initially instructed the cabin to remain seated. Between 30 and 45 seconds later, after identifying smoke and fire originating from the left main landing gear, the crew ordered an emergency evacuation.
The aircraft carried 175 occupants, comprising 169 passengers and six crew members. The NTSB final report confirms that zero injuries occurred during the event. This official casualty figure supersedes preliminary media reports from July 2025 that had indicated minor injuries and hospital evaluations.
The investigation report draws specific attention to passenger behavior during the emergency egress. The NTSB stated that the cabin crew described the evacuation as rapid but hindered by significant passenger confusion and noncompliance. Despite flight attendants repeatedly commanding passengers to leave their belongings behind, multiple individuals retrieved their carry-on baggage. The NTSB concluded that this noncompliance directly slowed the flow of egress from the aircraft.
AirPro News analysis
The NTSB findings regarding American Airlines Flight 3023 add to a well-documented and growing safety concern within the commercial aviation sector. Passenger retrieval of carry-on baggage during emergency evacuations is a recurring issue that compromises the 90-second evacuation standard mandated by the Federal Aviation Administration (FAA).
When passengers stop to open overhead bins and carry luggage down escape slides, they not only slow the egress rate for those behind them but also introduce the risk of puncturing the evacuation slides or injuring fellow passengers. We continue to see official accident reports cite passenger noncompliance as a negative factor in evacuation efficiency. This recurring behavioral pattern has prompted safety advocates and lawmakers to question whether current FAA evacuation certification tests, which rely on compliant participants, accurately reflect real-world human behavior during an emergency.
