NEW DELHI — Nearly three years after Air India Express Flight IX-1344 overshot the runway at Kozhikode’s Karipur International Airport, killing 21 people and injuring more than 150, India’s Aircraft Accident Investigation Bureau (AAIB) has signaled that its final report will deliver a definitive account of the tragedy. In a statement to media on Tuesday, a senior AAIB official confirmed the report would address not only what happened on June 7, 2023, but also how and why the Boeing 737-800 crashed during its second landing attempt in heavy monsoon rains. The announcement has intensified scrutiny of India’s aviation safety protocols, regulatory oversight, and the systemic vulnerabilities exposed by one of the country’s deadliest commercial air disasters in a decade.

What Happened: A Timeline of the Crash and Investigation
The accident unfolded at approximately 7:40 p.m. local time, when Air India Express Flight IX-1344, operating from Dubai to Kozhikode, attempted to land on Runway 10 at Karipur International Airport. According to preliminary findings released by the AAIB in August 2023, the aircraft touched down beyond the optimal touchdown zone, skidded off the runway, and plunged into a gorge, breaking into multiple sections. Both pilots—Captain Deepak Sathe, a former Indian Air Force officer, and First Officer Akhilesh Kumar—were among the 21 fatalities. The remaining 165 passengers and crew sustained injuries ranging from minor to critical, with many requiring emergency medical evacuation due to the airport’s limited trauma care facilities.
The AAIB’s investigation, launched immediately after the crash, has been one of the most complex in India’s aviation history. The bureau’s team, supported by experts from Boeing and the U.S. National Transportation Safety Board (NTSB), recovered and analyzed data from the flight data recorder (FDR) and cockpit voice recorder (CVR), reviewed air traffic control (ATC) communications, and interviewed survivors and ground personnel. Meteorological records from the India Meteorological Department (IMD) were also examined to reconstruct weather conditions at the time of the crash, which included heavy rainfall, low visibility, and strong crosswinds—factors that have been linked to previous runway overrun incidents in India.
The AAIB’s preliminary report, released two months after the crash, pointed to “adverse weather conditions” and “possible pilot disorientation” as contributing factors. However, the final report, now expected within weeks, is anticipated to provide a granular breakdown of the flight’s final minutes, including:
– Flight path deviations: Whether the aircraft descended too rapidly or deviated from the glide slope.
– Pilot decision-making: Why the crew proceeded with the landing despite reported weather warnings and whether fatigue or stress played a role.
– Runway conditions: The impact of standing water, rubber deposits, and braking efficiency on the aircraft’s deceleration.
– Airport infrastructure: The adequacy of Karipur’s runway safety area (RSA), which lacked an engineered materials arresting system (EMAS) at the time of the crash.
– ATC protocols: Whether air traffic controllers provided timely and accurate weather updates to the flight crew.
The AAIB has emphasized that the final report will be “evidence-based and exhaustive,” incorporating simulations of the flight’s dynamics and input from international aviation safety experts. The bureau’s spokesperson declined to comment on specific findings ahead of the report’s release but confirmed that recommendations for regulatory and operational reforms would be included.

Why It Matters: Aviation Safety Under the Microscope
The Kozhikode crash was not an isolated incident but the latest in a series of high-profile aviation accidents in India that have raised questions about the country’s ability to ensure safety amid rapid air traffic growth. With domestic passenger numbers projected to exceed 300 million annually by 2030—up from 144 million in 2023—India’s aviation sector is expanding at a pace that has strained infrastructure, regulatory oversight, and pilot training programs.
The AAIB’s final report is expected to have far-reaching implications for:
1. Regulatory Reforms: The Directorate General of Civil Aviation (DGCA), India’s aviation regulator, has faced criticism for lax enforcement of safety standards, particularly at regional airports. The Kozhikode crash prompted the DGCA to mandate EMAS installations at 10 high-risk airports, but implementation has been slow. The AAIB’s findings could accelerate these reforms or introduce new requirements, such as stricter weather-related landing protocols.
2. Airport Infrastructure: Karipur International Airport, a key hub for Kerala’s expatriate workforce, has long been flagged for safety concerns. In 2010, an Air India Express flight overshot the same runway, killing six people. The AAIB’s report may renew calls for runway extensions, improved drainage systems, and better lighting—upgrades that have been delayed due to land acquisition disputes and funding shortages.
3. Pilot Training and Fatigue Management: The crash has reignited debates about pilot workload and training standards. Captain Sathe, a veteran with over 10,000 flight hours, was reportedly on his fifth consecutive day of duty. The AAIB’s report could recommend revisions to India’s flight duty time limitations (FDTL) regulations, which currently allow pilots to fly up to 125 hours per month—a threshold some experts argue is too high.
4. International Scrutiny: India’s aviation safety record has been under the spotlight since the International Civil Aviation Organization (ICAO) conducted an audit in 2022, which identified “significant safety concerns” in areas such as airworthiness certification and accident investigation. The AAIB’s report could influence India’s standing in the ICAO’s Universal Safety Oversight Audit Programme (USOAP), which affects the country’s ability to expand international routes.
5. Corporate Accountability: Air India Express, a low-cost subsidiary of the state-owned Air India, has faced scrutiny over its safety culture and maintenance practices. The airline has already implemented some changes, including enhanced pilot training on monsoon operations, but the AAIB’s report may lead to further operational restrictions or financial penalties.

Background and Context: India’s Aviation Safety Challenges
The Kozhikode crash did not occur in a vacuum. India’s aviation sector has grappled with safety issues for decades, shaped by rapid growth, regulatory gaps, and infrastructure bottlenecks. Key contextual factors include:
# 1. Runway Overruns: A Recurring Hazard
Runway overruns have been a persistent problem in India, accounting for nearly 30% of all commercial aviation accidents in the country since 2000. Notable incidents include:
– 2010 Mangalore Crash: An Air India Express flight overshot the runway at Mangalore’s Bajpe Airport, killing 158 people. The AAIB’s report cited pilot error and a “non-stabilized approach” as primary causes. The accident led to the installation of EMAS at Mangalore, but similar upgrades were not mandated at other high-risk airports, including Kozhikode.
– 2015 Mumbai Incident: A Jet Airways flight skidded off the runway at Mumbai’s Chhatrapati Shivaji Maharaj International Airport during heavy rains, injuring 20 passengers. The DGCA later found that the runway’s grooving—designed to improve drainage—had worn down, reducing braking efficiency.
– 2019 Goa Overrun: A SpiceJet aircraft veered off the runway at Goa’s Dabolim Airport, injuring 13 people. The AAIB attributed the incident to a “loss of directional control” due to wet runway conditions.
These incidents highlight a pattern of systemic risks, including inadequate runway safety areas, poor drainage, and inconsistent enforcement of weather-related landing protocols.
# 2. Monsoon Operations: A Seasonal Threat
India’s monsoon season (June to September) poses unique challenges for aviation, including:
– Low Visibility: Heavy rainfall and fog can reduce visibility to less than 500 meters, complicating landings.
– Wet Runways: Standing water reduces braking efficiency, increasing the risk of hydroplaning. The DGCA mandates that runways be “dry” or “damp” for landings, but enforcement is inconsistent.
– Crosswinds: Strong gusts can destabilize aircraft during landing, particularly at airports with short runways like Kozhikode (2,860 meters).
Despite these risks, many Indian airports lack advanced instrument landing systems (ILS) or ground-based augmentation systems (GBAS) that could improve precision landings in poor weather. The AAIB’s report may recommend accelerated adoption of these technologies.
# 3. Regulatory Oversight: The DGCA’s Struggles
The DGCA, tasked with enforcing aviation safety standards, has been criticized for:
– Understaffing: The regulator has fewer than 500 inspectors to oversee over 1,000 aircraft and 100+ airports, leading to infrequent audits and delayed enforcement actions.
– Conflict of Interest: The DGCA is responsible for both promoting the aviation sector and regulating it, a dual mandate that critics argue compromises safety oversight.
– Slow Reforms: The DGCA has been slow to implement recommendations from past accident reports. For example, the 2010 Mangalore crash report called for EMAS installations at all tabletop runways (elevated runways with steep drops at the ends), but Kozhikode’s runway lacked this safety feature until after the 2023 crash.
In 2022, the Indian government announced plans to replace the DGCA with a new, independent aviation safety regulator, but the proposal has stalled due to bureaucratic hurdles.
# 4. Pilot Training and Fatigue: A Growing Concern
India’s pilot shortage—exacerbated by the pandemic and rapid fleet expansion—has led to concerns about training standards and fatigue management. Key issues include:
– Simulator Training: Many Indian airlines rely on outdated simulators that do not accurately replicate monsoon conditions or runway overrun scenarios.
– Flight Duty Time: India’s FDTL regulations allow pilots to fly up to 125 hours per month, higher than the 100-hour limit recommended by the International Air Transport Association (IATA). Fatigue has been cited as a contributing factor in several incidents, including the 2015 Mumbai overrun.
– Crew Resource Management (CRM): The AAIB’s preliminary report on the Kozhikode crash noted that the pilots did not conduct a “go-around” (aborting the landing) despite unstable approach conditions. This has raised questions about CRM training, which emphasizes communication and decision-making in the cockpit.

Competing Claims and Uncertainty: What the Final Report May (or May Not) Reveal
While the AAIB’s final report is expected to provide a comprehensive account of the Kozhikode crash, several key questions remain unanswered, and competing narratives have emerged:
# 1. Pilot Error vs. Systemic Failures
– Pilot Error: Some aviation experts argue that the crash was primarily the result of pilot error, citing the crew’s decision to land in poor weather and their failure to execute a go-around. Captain Sathe, though experienced, had limited exposure to monsoon landings at Kozhikode, and the AAIB’s preliminary report noted that the aircraft’s descent rate was “higher than normal.”
– Systemic Failures: Others contend that the crash was the result of broader systemic issues, including:
– Airport Design: Karipur’s runway lacks an EMAS and has a steep drop at the end, making overruns more dangerous.
– ATC Communications: Survivors and ground personnel have alleged that ATC did not provide timely weather updates or warn the crew about standing water on the runway.
– Aircraft Maintenance: Air India Express has faced scrutiny over its maintenance practices, including allegations of deferred repairs and inadequate spare parts inventory.
