What is Tejas? The Aircraft at the Centre of the Disaster
The Tejas Light Combat Aircraft (LCA) is a 4.5-generation, multi-role fighter jet designed by India’s HAL (Hindustan Aeronautics Limited), capable of offensive air support, close combat, ground attack mission and maritime operations.
The aircraft is known for being lightweight, highly maneuverable, and fitted with cutting-edge systems.
The latest LCA Mk-1A variant incorporates major upgrades including AESA radar (Active Electronically Scanned Array), electronic warfare suite, radar warning receiver, jamming capability, digital map generator, smart multi-function cockpit displays, combined IFF (Identification Friend/Foe) interrogator-transponder, modern radio altimeter and improved survivability and combat handling.
For more than two decades, India’s home-grown HAL Tejas maintained one of the cleanest safety records in global fighter aviation. Since its maiden flight in 2001, the Tejas completed more than 10,000 test+ operational sorties without a single crash — a milestone unmatched by many foreign fighter programmes.
Remarkable Beginning of Tejas: 23 Years, Zero Crashes
The Tejas made its first flight on January 4, 2001, marking the start of India’s indigenous fighter programme’s most critical phase. From that day onward, and for twenty-three continuous years, the LCA flew close to 5,000 developmental test flights, thousands of squadron-level sorties, weapons trials, high-G manoeuvres, and long-endurance missions, regular operational deployments. All without a single accident.
This spotless record placed Tejas among the safest light combat aircraft ever developed, especially compared to foreign jets that suffered multiple crashes even during early testing.
First Crash: March 12, 2024 — Jaisalmer Training SortieTwenty-three years after it first took to the skies, the Tejas LCA experienced its first accident on March 12, 2024, during an operational training sortie near Jaisalmer, Rajasthan.
The key facts of the incident in Jaisalmer include that the pilot ejected safely, sustaining no serious injuries, a court of Inquiry pointed to a likely engine seizure (GE 404). The seizure was traced to an oil pump malfunction. Crucially, investigators ruled out any design flaw or systemic issue in the Tejas fleet
In other words, it was an isolated mechanical failure — not a reflection of the aircraft’s aerodynamics, systems reliability, or structural performance.
Possible Causes Under Investigation
A crash during a display flight can stem from one or more of three broad categories that include technical failure, human error and operational overreach (pushing aircraft or pilot limits). The Court of Inquiry will examine all three.
Technical Malfunction: A Strong Possibility
Even the most advanced aircraft can face sudden failures. Potential technical glitches include:
Engine failure: High-thrust maneuvers during air shows put enormous stress on engines. A flameout, compressor stall, or loss of power can be catastrophic at low altitude.
Air show flying is far riskier than standard operational flying. Pilots often operate at lower altitudes, higher speeds, sharper turns, tighter margins
A slight miscalculation during a dramatic maneuver could cause the aircraft to lose lift or altitude faster than expected. At high speed, even a one-second delay in recovery can mean the difference between a near-miss and impact.
Air shows often tempt pilots to perform more dramatically, more sharply, or more aggressively than standard protocols allow.
Investigators will examine whether the pilot Attempted a maneuver at an unsafe speed or altitude. Tried to tighten a loop or roll beyond planned parameters Or Pushed G-limits or angle-of-attack beyond safety thresholds and Tried to outperform his own rehearsal routine or previous displays.
