DGCA Launches Investigation into Air India Safety Lapse

India’s aviation regulator, the Directorate General of Civil Aviation (DGCA), has initiated a formal probe into Air India after the flag carrier operated a commercial aircraft with an expired safety certificate. According to reporting by Reuters, the airline flew an Airbus A320 on multiple revenue flights in late November 2025 without a valid Airworthiness Review Certificate (ARC), a mandatory document that validates an aircraft’s fitness to fly.

The incident has triggered immediate regulatory action, including the grounding of the specific aircraft and the de-rostering of engineering personnel responsible for the oversight. This development places renewed scrutiny on Air India’s safety protocols as the airline navigates a complex merger with Vistara.

Incident Timeline and Immediate Fallout

The violation involved an Airbus A320, registered as VT-TQN, which was reportedly one of the aircraft recently inducted into Air India’s fleet from Vistara. According to details summarized in reports by The Economic Times, the aircraft operated eight revenue flights over a two-day period between November 24 and November 25, 2025.

The lapse went undetected until November 26, when Air India’s internal checks identified the expired certificate. The airline subsequently informed the regulator voluntarily. In response, the DGCA ordered the aircraft to be grounded immediately. Both the airline and the regulator have launched separate investigations to determine how the aircraft was cleared for service.

In a statement regarding the incident, an Air India spokesperson acknowledged the failure:

“An incident involving one of our aircraft operating without an airworthiness review certificate is regrettable. As soon as this came to our notice, it was duly reported to the DGCA.”

The Role of the Vistara Merger

The operational oversight appears to be linked to the logistical challenges of merging Vistara’s fleet into Air India. Reports indicate that the aircraft in question was the final plane in a batch of 70 former Vistara aircraft undergoing induction. The ARC expired while the plane was grounded for a scheduled engine change. Once the maintenance was completed, engineering staff allegedly released the aircraft for flight without verifying that the ARC had been renewed, a critical step in the post-maintenance release process.

Understanding the Regulatory Violation

Under India’s Civil Aviation Requirements (CAR), specifically Section 2, Series F, an Airworthiness Review Certificate (ARC) is non-negotiable for commercial operations. It functions as an annual “health check” that validates the aircraft’s Certificate of Airworthiness. Operating without this document is a violation of the Aircraft Rules, 1937, and technically renders the aircraft unairworthy for the duration of those flights.

The DGCA has taken a strict stance on such violations, viewing them as “Level 1” safety lapses because they bypass the fundamental checks and balances designed to ensure passenger safety.

Broader Safety Concerns

This incident is the latest in a series of regulatory hurdles for Air India. The airline has faced consistent scrutiny regarding its safety culture throughout 2024 and 2025. According to reporting by The Hindu, a major DGCA audit conducted in July 2025 flagged 51 safety lapses within the airline’s operations. These findings included deficiencies in pilot training, improper use of simulators, and issues with crew rostering that potentially contributed to fatigue.

The regulator has previously imposed financial penalties on the carrier for similar operational breaches, including fines for pilot qualification issues and violations of flight duty time limitations.

AirPro News analysis

While Air India has characterized this event as a regrettable error discovered through internal checks, the incident highlights a significant vulnerability in the airline’s transition phase. The integration of Vistara, a process involving the unification of fleets, personnel, and digital systems, creates a high-risk environment for administrative and operational slips.

The core issue here may not be solely human error but a failure of digital safeguards. In a robust safety management system, maintenance software should theoretically prevent an aircraft with an expired ARC from being rostered for revenue flights. The fact that the plane completed eight sectors suggests a potential gap in the digital “hard stops” that are supposed to prevent such regulatory breaches. As the DGCA investigation proceeds, the focus will likely shift from the individual engineers to the systemic safeguards that failed to catch the expiration.

FAA Expands Surface Awareness Initiative to 55 Additional Airports

On November 24, 2025, the Federal Aviation Administration (FAA) awarded a significant contract to uAvionix Corporation, marking a major expansion of the agency’s efforts to enhance runway safety. The agreement mandates the deployment of the FlightLine Surface Awareness Initiative (SAI) system at 55 additional airports across the United States. This move represents a decisive shift from pilot programs to a nationwide rollout, aiming to equip Air Traffic Control (ATC) towers with advanced surface surveillance capabilities.

The contract stipulates an aggressive timeline, requiring uAvionix to install, test, and achieve full operational status at all 55 sites within 12 months. By November 2026, these airports are expected to possess “radar-like” situational awareness, a capability previously reserved for major hubs equipped with expensive ground radar-systems. This initiative addresses a critical gap in aviation safety by targeting airports that have high traffic volumes or a history of “wrong surface” events but lack traditional surveillance tools.

This expansion is a cornerstone of the FAA’s broader “Surface Safety Portfolio” and aligns with the current administration’s “Brand New Air Traffic Control System” (BNATCS) initiative. By prioritizing commercially available technologies over bespoke, capital-intensive infrastructure projects, the FAA aims to modernize the National Airspace System (NAS) rapidly. The selection of uAvionix follows a series of successful deployments at initial sites, validating the effectiveness and speed of the FlightLine SAI system.

Technological Shift: From Radar to ADS-B

The FlightLine SAI system represents a fundamental departure from legacy surface surveillance methods such as ASDE-X (Airport Surface Detection Equipment, Model X). While traditional systems rely on primary radar and multilateration to track ground movements, FlightLine SAI utilizes Automatic Dependent Surveillance-Broadcast (ADS-B) data. This cloud-based solution captures precise location data broadcast by aircraft and vehicles, displaying it on a map for tower controllers. This approach allows for a clear, real-time depiction of the airfield, regardless of visual conditions.

A key component of this technological ecosystem is the integration of ground vehicles into the surveillance network. The contract includes the deployment of VTU-20 Vehicle Movement Area Transmitters (VMATs). These devices are installed on airport and FAA TechOps vehicles, ensuring they are visible to both controllers and pilots. By broadcasting their positions, these vehicles become part of the digital surface picture, significantly reducing the risk of collisions between aircraft and ground support equipment.

The operational advantages of this system are particularly pronounced during adverse weather. Unlike optical visibility, which is compromised by fog, rain, or darkness, ADS-B data remains consistent. Controllers are provided with a “see-through” capability, allowing them to monitor runway occupancy and taxiway movements with high precision. This data-driven approach enhances decision-making speed and accuracy, directly contributing to the reduction of runway incursions.

“The system provides real-time, precise depictions of all ADS-B equipped aircraft and vehicles on the airport surface, enabling proactive management of potential conflicts, especially critical during low-visibility conditions.”

Rapid Deployment and Strategic Implementation

The 12-month deadline for 55 airports underscores a new emphasis on agility within the FAA’s procurement and deployment strategy. Historically, installing surface surveillance infrastructure could take years. However, the FlightLine SAI system utilizes Commercial Off-The-Shelf (COTS) technology, which drastically reduces installation times. uAvionix has previously demonstrated this capability by completing installations at Richmond International (RIC) and Charleston International (CHS) in fewer than 90 days, with some reports citing a completion time of just 69 days.

While the FAA has not released a consolidated public list of the specific 55 airports included in this latest contract, the expansion builds upon an initial cohort of sites. Airports such as Austin-Bergstrom International (AUS), Indianapolis International (IND), and Jacksonville International (JAX) were among the first to receive the technology. The new contract targets mid-sized hubs and airports with complex runway geometries that require enhanced monitoring. Likely candidates include facilities identified in the FAA’s Surface Safety Portfolio that currently lack major ground radar systems.

This initiative is part of a triad of fast-tracked technologies aimed at surface safety. Alongside SAI, the FAA is deploying Approach Runway Verification (ARV), which alerts controllers if a pilot aligns with the wrong runway, and the Runway Incursion Device (RID), a memory aid for tracking closed or occupied runways. The simultaneous rollout of these technologies reflects a comprehensive strategy to layer safety redundancies and modernize air traffic control operations without the extended timelines associated with traditional federal infrastructure projects.

Conclusion

The awarding of this contract to uAvionix signals a definitive step toward modernizing surface safety across the United States aviation network. By leveraging agile, cloud-based technologies, the FAA is moving to close the safety gap at dozens of airports within a single year. The successful execution of this 12-month plan will likely serve as a blueprint for future NAS upgrades, demonstrating that safety enhancements can be delivered rapidly and cost-effectively.

As the aviation industry continues to face challenges related to traffic volume and operational complexity, the reliance on data-driven, satellite-based surveillance will become increasingly standard. The FlightLine SAI rollout not only improves immediate safety metrics but also prepares the infrastructure for future integrations of digital air traffic management tools.

Airbus Issues Precautionary Fleet Action Following Solar Radiation Incident

On November 28, 2025, Airbus announced a significant precautionary fleet action impacting approximately 6,000 A320-family aircraft, representing roughly half of the global fleet for this type. This decision follows a comprehensive investigation into a specific technical vulnerability triggered by environmental factors. The action is being coordinated with the European Union Aviation Safety Agency (EASA) and involves an Emergency Airworthiness Directive (EAD) to ensure the continued airworthiness of the affected airframes.

The catalyst for this widespread measure was a serious in-flight incident involving a JetBlue Airways flight on October 30, 2025. During a scheduled flight from Cancun to Newark, the aircraft experienced an uncommanded descent caused by corrupted flight control data. While the pilots successfully regained control and performed an emergency landing in Tampa, the event resulted in injuries to at least 15 passengers. Subsequent analysis identified that intense solar radiation had compromised the integrity of the flight control computer’s data processing.

We are seeing immediate operational responses across the aviation industry as airlines work to comply with the directive. The required maintenance actions vary depending on the age of the aircraft, ranging from software updates for newer models to hardware replacements for older units. This event has triggered notable financial fluctuations for major carriers and Airbus itself, while raising important questions regarding passenger compensation and the resilience of modern avionics against cosmic radiation.

Technical Analysis: The JetBlue Incident and Avionics Vulnerability

The investigation led by the National Transportation Safety Board (NTSB) and Airbus engineers pinpointed the root cause of the October 30 incident to a phenomenon known as a Single Event Upset (SEU). During the JetBlue flight, high-energy particles, attributed to solar flares or cosmic rays, struck the aircraft’s avionics system. This interaction caused a “bit flip” in the Thales ELAC 2 (Elevator Aileron Computer), changing a binary zero to a one, or vice versa. This microscopic alteration corrupted the data stream, leading the computer to interpret stable flight conditions as a command to initiate a dive, effectively overriding the autopilot systems.

The Role of the ELAC 2

The Elevator Aileron Computer (ELAC) is a critical component of the A320’s “fly-by-wire” architecture. It interprets pilot inputs and sensor data to manipulate the aircraft’s control surfaces, specifically the elevators for pitch control and ailerons for roll control. When the ELAC 2 experienced the radiation-induced data corruption, it commanded a sudden pitch-down maneuver. This highlights a specific vulnerability in modern, miniaturized electronics, which, while efficient, can be more susceptible to interference from high-energy atmospheric particles compared to older, larger components.

Industry experts have drawn parallels between this event and the Qantas Flight 72 incident in 2008. in that case, an Airbus A330 experienced a similar uncommanded pitch-down due to a data spike in its Air Data Inertial Reference Unit (ADIRU), also linked to cosmic radiation. These events underscore the challenge of designing redundancy systems that can distinguish between legitimate emergency maneuvers and data errors caused by transient environmental factors. The recurrence of such an event suggests that while rare, “bit flips” remain a persistent variable in aviation safety engineering.

“The fact that a single bit flip could cause a significant flight control excursion suggests a potential lack of sufficient redundancy or error-checking in the specific software version running on the ELAC 2.”, Aviation Safety Experts

Scope of the Fleet Action

The remedial action mandated by Airbus and EASA is divided into two distinct categories based on the hardware generation of the aircraft. Group 1, comprising approximately 4,000 newer aircraft, requires a software update. This process involves reverting the ELAC system to a previous software standard that has proven less sensitive to this specific type of data corruption. We understand that this update is relatively efficient, taking approximately 30 minutes per aircraft, allowing many carriers to perform the work overnight with minimal schedule disruption.

Group 2 presents a more complex logistical challenge. This group includes approximately 2,000 older aircraft that require a physical replacement of the ELAC unit. Unlike the software patch, this hardware intervention could ground affected planes for days or even weeks, depending on the availability of spare parts from the supplier, Thales. Supply-Chain analysts have warned that this requirement could strain the availability of avionics components, potentially extending the grounding period for airlines with older fleets.

Operational Impact and Market Reaction

The announcement on November 28, 2025, caused immediate and severe repercussions in the financial-results markets and airline flight schedules. Airbus SE shares dropped to a four-week low of €202.45, reflecting investor concern over the scale of the recall and the potential reputational impact regarding supply chain resilience. However, the swift issuance of the directive is also being viewed by some as a responsible and necessary step to prioritize safety above operational continuity.

Airline-Specific Disruptions

Carriers with heavy reliance on the A320 family are facing the steepest challenges. JetBlue, an all-Airbus operator, saw its stock value plummet by more than 28%. This drop was compounded by an already weak financial outlook for 2025. Similarly, Wizz Air shares fell by approximately 12%, with the airline cutting its profit guidance and citing the grounding of aircraft as a primary driver for the revision. In the Indian market, carriers like IndiGo and Air India are facing significant groundings, with hundreds of flight cancellations expected over the initial weekend following the announcement.

Conversely, legacy carriers with more diverse fleets appear to be better positioned to absorb the shock. American Airlines confirmed that while approximately 340 of its aircraft are affected, it expects to complete the necessary software updates within 24 to 48 hours. British Airways and EasyJet have signaled that they expect “some disruption,” but the impact is mitigated by their mix of newer aircraft and the ability to deploy alternative planes to cover affected routes.

Consumer Rights and Compensation

A major point of contention emerging from this crisis is the eligibility of passengers for compensation regarding delays and cancellations. Airlines are expected to classify these disruptions as “Extraordinary Circumstances” or force majeure, arguing that solar radiation is an act of nature beyond their control. Under Regulations like EU261 and UK261, such a classification would typically exempt airlines from paying compensation.

However, legal experts and passenger rights advocates are likely to challenge this stance. Precedents set by court cases such as Sturgeon v Condor and Huzar v Jet2 have established that technical problems inherent to the normal operation of an airline are not extraordinary. The argument follows that since cosmic radiation is a known risk of high-altitude flight, and avionics are specifically designed to be shielded against it, a failure of that shielding or software constitutes a technical defect rather than a freak weather event. We anticipate that while airlines may initially deny claims, legal challenges could eventually force payouts if courts rule that the component failure represents a manufacturing or design weakness.

Concluding Section

The precautionary fleet action initiated by Airbus represents a massive logistical undertaking and highlights the intricate relationship between advanced aviation technology and the natural environment. While the immediate focus is on the rapid deployment of software updates and hardware replacements to ensure passenger safety, the long-term implications involve a re-evaluation of avionics redundancy and supply chain robustness. The industry must balance the benefits of miniaturized, digital fly-by-wire systems with the necessity of hardening these systems against rare but high-impact environmental anomalies.

As the situation develops, the aviation sector will be closely monitoring the speed of the hardware rollout for the 2,000 older aircraft and the legal outcomes regarding passenger compensation. This event serves as a reminder that as aircraft become more digitally dependent, their vulnerability to non-traditional threats, such as cosmic radiation, requires constant vigilance and evolution in engineering standards.
