Analysis: technical, human and environmental factors under scrutiny
DUBAI — The fatal crash of an Indian Air Force (IAF) Tejas fighter jet during a demonstration at the Dubai Air Show has raised serious questions about possible technical, operational, and environmental causes behind the tragic incident that killed the pilot on Friday.
The HAL-built Tejas, India’s indigenous lightweight combat aircraft, went down inside the grounds of Al Maktoum International Airport moments after completing several passes over the exhibition area. Eyewitness footage showed the jet losing control before nosediving into the ground around 2:10 p.m. local time, triggering black smoke and emergency sirens across the venue.
While the Indian Air Force has ordered a court of inquiry, preliminary aviation assessments suggest that multiple potential factors could have contributed to the accident:
Possible technical malfunction
The Tejas is a single-engine fighter, and any disruption in thrust, fuel flow, or engine response during high-speed aerobatic maneuvers can rapidly become unrecoverable—especially at low altitude.
A sudden loss of power, control-surface failure, or flight-control system glitch could explain why the aircraft appeared to pitch downward sharply. Although the Tejas has generally performed reliably, the program has faced known issues in the past, including:
- delays due to imported engine shortages
- integration challenges with its flight-control systems
- high pilot-workload during extreme maneuvers
However, no official indication has yet been made that a mechanical failure occurred.
Aerobatic risk at low altitude
Demonstration flights at air shows require aggressive turns, rapid climbs, and sharp directional changes—leaving pilots very little margin for error. The Tejas pilot had already made several passes, suggesting the aircraft was engaged in high-stress maneuvers.
If the aircraft entered a stall or lost lift due to angle-of-attack misjudgment, recovery would have been extremely difficult at the height shown in videos.
Air show accidents worldwide have historically occurred during:
- low-altitude loops
- high-G turns
- high-speed dives
- tight roll maneuvers
A small miscalculation or misjudgment could therefore have been catastrophic.
Pilot factors also under review
Although IAF pilots are among the region’s most skilled, stress factors such as G-forces, spatial disorientation, or momentary overload cannot be ruled out.
In several past global air-show crashes, pilots faced sudden physiological strain while performing complex sequences. The Tejas cockpit is highly digital, but quick corrective action is still required during aerobatics.
Environmental conditions
Dubai’s weather is typically clear but can involve:
- strong crosswinds
- sudden thermal air pockets
- high temperatures affecting engine thrust
Any of these could have contributed to instability, especially during steep ascents or tight turns.
Implications for India’s defense aviation program
The crash comes at a critical time for India:
- A fresh contract for 97 Tejas jets was signed in September 2025.
- An earlier order for 83 jets has already faced delays due to imported engine shortages.
- The aircraft is central to India’s strategy to replenish its fighter fleet amid regional tensions with China and Pakistan.
While a single accident does not determine an aircraft’s reliability, the visibility of a crash at a major international air show puts additional scrutiny on HAL’s manufacturing quality, the aircraft’s safety record, and IAF training procedures for demonstration flights.
Investigations ahead
The Indian Air Force has said it “deeply regrets the loss of life” and confirmed that a detailed inquiry will determine the precise cause. No findings have yet been disclosed.
Dubai authorities have not publicly commented, but their cooperation with IAF and HAL investigators is expected.
Until the inquiry concludes, aviation experts caution against speculation but agree that the crash underscores the inherent risks of high-performance air-show displays—particularly for single-engine fighters performing at low altitudes.
