A comprehensive analysis conducted by India’s civil aviation ministry has unveiled a significant challenge facing the nation’s rapidly expanding airline sector: nearly 50% of the commercial aircraft fleet examined exhibited recurring technical defects. This revelation, stemming from an audit covering 754 planes between January 2025 and February 2026, highlights the intricate balance between unprecedented growth and the imperative of maintaining operational integrity and safety standards in one of the world’s fastest-growing aviation markets.
Minister of State for Aviation, Murlidhar Mohol, confirmed that 377 aircraft were identified with persistent issues, which are defined as malfunctions or maintenance problems reappearing on the same aircraft despite previous repair attempts. These issues often signify that the underlying root cause, such as a faulty component or an inadequate repair procedure, has not been definitively addressed. While some of these recurring problems can pertain to safety-critical systems, a substantial portion, particularly those highlighted by airline executives, relate to cabin amenities and non-essential operational components, such as inoperative entertainment screens, loose tray tables, or worn seat upholstery. However, even non-critical recurring defects can impact passenger experience, airline reputation, and contribute to operational delays.
The detailed breakdown of the ministry’s findings reveals varying degrees of prevalence across major Indian carriers. IndiGo, the country’s largest airline by market share, reported recurring faults in 148 of its 405 analyzed aircraft, meaning approximately one in three of its planes encountered such issues during the period. Given IndiGo’s extensive network and daily flight count, the sheer volume of operations underscores the scale of managing even minor recurring defects across its substantial fleet.
However, the Air India Group, comprising full-service carrier Air India and low-cost subsidiary Air India Express, showed a significantly higher incidence. A striking 71% of its analyzed fleet, or 191 out of 267 aircraft, were found to have recurring defects. Within the group, Air India itself registered an even higher figure, with 82% (137 out of 166 planes) of its fleet experiencing repetitive problems. Air India Express, in contrast, reported a rate of nearly 53%, or 54 out of 101 aircraft. For context, the Air India group operates a total fleet of 297 aircraft, while IndiGo’s operational fleet stands at 440. Other carriers also showed notable figures: SpiceJet recorded recurring defects in 37% (16 of 43 analyzed aircraft), and Akasa Air, a relatively newer entrant, showed 14 out of its 32 aircraft (44%) with recurring issues.
An Air India spokesperson acknowledged the figures, attributing the higher numbers to an "abundance of caution" in conducting fleet-wide checks. The airline emphasized that many of the identified issues were non-safety-related, focusing on cabin interiors and passenger comfort elements. A top Air India executive further elaborated, stating that the airline’s ongoing retrofit program for its narrow-body aircraft, slated for completion over the next two years, is expected to resolve many of these cabin-related issues. This distinction between safety-critical and non-safety-critical defects is crucial for understanding the immediate implications for flight operations and passenger safety, though both types of issues contribute to operational costs and impact passenger satisfaction.
Aviation experts corroborate that not all recurring defects bear direct implications for flight safety. Captain Mohan Ranganathan, a former member of the Civil Aviation Safety Advisory Council, shed light on the Minimum Equipment List (MEL) protocol, a regulatory framework that categorizes aircraft components based on their criticality. Equipment categorized as ‘A’ requires immediate repair or replacement, typically within the same day, due to its critical safety function. ‘B’ category items allow for a 72-hour window, while ‘C’ category components, which do not negatively impact aircraft safety, permit replacement or repair within 10 days.
Captain Ranganathan pointed out a practice where airlines might strategically swap defective ‘C’ category parts, such as an air conditioning pack, between aircraft. This maneuver effectively grants an airline an additional 10 days to source and install a permanent replacement, as the "new" aircraft now has its own 10-day repair window for that component. While not illegal or directly unsafe for ‘C’ category items, this practice, if not meticulously tracked, could obscure the true frequency and location of component failures. Ranganathan suggested that a robust digital trail could provide aviation regulators with better insights into such operational tactics and potentially identify systemic component weaknesses.
The economic implications of these recurring defects are multifaceted. Airlines incur significant costs related to maintenance, repair, and overhaul (MRO), spare parts inventory, and potential aircraft downtime. Even minor defects can lead to delays or cancellations, resulting in lost revenue, compensation payouts to passengers, and damage to brand reputation. For a market like India, projected to become the third-largest aviation market globally by 2024, such operational inefficiencies could impede its growth trajectory and deter international business and tourism. The MRO sector in India is still relatively nascent, with many complex repairs and overhauls outsourced to facilities in Singapore, Dubai, or Europe, adding to logistics challenges and costs. Enhancing domestic MRO capabilities could significantly alleviate these pressures.
Beyond the immediate financial impact, persistent technical issues, even non-safety-critical ones, chip away at passenger confidence. In an increasingly competitive market, airlines striving for differentiation and loyalty must ensure a seamless and comfortable travel experience. Frequent delays due to minor technical glitches, or visible signs of wear and tear, can negatively influence passenger perception and choice. This is particularly relevant for Air India, which is undergoing a major brand and service overhaul under Tata Group ownership, aiming to reclaim its position as a premium global carrier.
From a regulatory standpoint, the Directorate General of Civil Aviation (DGCA) faces the critical task of strengthening its oversight mechanisms. While MEL guidelines provide a structured approach to managing defects, the sheer volume of recurring issues across the fleet suggests a need for deeper investigation into root causes. This could involve more stringent audits of airline maintenance protocols, greater scrutiny of MRO facilities, and leveraging data analytics to identify patterns that might indicate widespread component reliability issues or training deficiencies among maintenance personnel. International standards set by bodies like the International Civil Aviation Organization (ICAO) emphasize proactive safety management systems, requiring airlines to continuously monitor and mitigate risks.
Looking ahead, addressing these challenges requires a concerted effort from all stakeholders. Airlines must invest in fleet modernization, particularly carriers with older aircraft, and enhance their in-house MRO capabilities and data-driven maintenance strategies. This includes adopting predictive maintenance technologies that utilize sensor data and artificial intelligence to anticipate component failures before they occur. Regulators need to evolve their oversight to not only react to incidents but also proactively identify systemic risks through advanced data analysis and more frequent, unannounced inspections. Furthermore, fostering a robust domestic MRO ecosystem through policy support and investment incentives will be crucial for India to sustain its aviation growth while ensuring the highest standards of safety and operational reliability. The current findings serve as a critical checkpoint, urging the Indian aviation sector to reinforce its foundations as it continues its ambitious ascent in the global skies.
