Indian Air Force shot down its helicopter on Feb 27

NEW DELHI: The Indian Air Force’s inquiry into the accidental shoot down of its own Mi-17 chopper on February 27 will be over within 20 days. The summary of evidence will be presented immediately afterwards and those responsible for the death of 6 IAF personnel onboard the chopper and a civilian on the ground may be charged with culpable homicide not amounting to murder as specified by military law under the Air Force Act 1950.

Sources in the Indian Air Force have told NDTV that there was never any doubt on the outcome of the launch of an Israeli-made SPYDER surface-to-air missile on February 27 from the Srinagar air base. The investigation has taken time because the IAF is determined to apportion blame for this incident. IAF sources have indicated to NDTV that the entire shoot-down sequence from the moment the missile was launched to the moment of impact lasted approximately 12 seconds. The Mi-17 helicopter had no means of knowing it was under attack. NDTV has also learned of the likely sequence of events which resulted in an incorrect decision to launch the surface-to-air missile.

Between 10 and 10:30 am on the morning of February 27, eight Indian Air Force fighters were vectored to intercept upto 24 Pakistan Air Force fighters including a group of F-16s which crossed the Line of Control and fired weapons in the direction of Indian Army positions along the Line of Control in Jammu and Kashmir.

With an active air battle raging on the West, air defences across Kashmir were on the highest state of alert with surface-to-air missile units on alert and ready to engage any Pakistani aircraft which made an incursion.It was at this same time that air defence radars at Srinagar airport picked up a low flying aircraft on their screens. The senior officer manning the post of Terminal Weapons Director (TWD) at the time was likely the Chief Operations Officer of the Air Base.

This officer may have given the final order to fire after the helicopter, designated a slow flying target, could not be identified through a critical system called the Identification, Friend or Foe (IFF) transponder.

IFF systems onboard an aircraft listen for an ‘’interrogation signal’’ from the ground and then respond with a unique signal which identifies it as a ‘’friendly.’’ The system is specifically designed to ensure that friendly-fire incidents are avoided during the heat of battle. It is unclear if the IAF helicopter’s IFF was switched off or was not functioning at the time when it was shot down.

Sources have indicated to NDTV that a series of additional steps may not have been followed in the moments prior to the launch of the Spyder surface-to-air missile. The role of the Indian Air Force’s Air Traffic Control at Srinagar airbase is also being looked at very closely by the Court of Inquiry. ATC maintains a flight plan of all aircraft that have taken off or are expected at the air base.

It is unclear whether the Terminal Weapons Director inquired and was told by the ATC that no friendly aircraft were flying in the area.
