MOD responds to Hercules C-130 crash allegations
03/05/2006
On 30 January 2005, a Hercules C130K crashed in Iraq with the loss of all personnel on board. In December 2005 the Board of Inquiry concluded that the aircraft crashed after it became uncontrollable after hostile ground-to-air fire caused the explosive separation of the outboard right hand wing.
One of the contributing factors identified by the Board was the lack of a fuel-tank inerting system. Whilst such a system may have prevented an explosion in the wing, the Board concluded that it would not necessarily have prevented a fire.
Although such a system would have increased the probability of the aircraft’s survival, neither the Board of Inquiry nor the Independent Senior Air Accident Investigator, concluded that it would definitely have changed the tragic outcome. Defensive aides are only part of the protection for the aircraft, which is why the RAF invests heavily in developing the best tactics, force protection measures and flight deck armour.
Since 2001, the defensive aides for C-130s have been upgraded several times. New Directional Infra Red Counter Measures, Missile Approach Warning Systems, Radar Warning Receivers, Countermeasures Dispensing Systems and additional flight deck armour have all been added. Prior to the C-130 crash in Iraq, it was judged that there was a low risk of a fuel tank explosion.
The emphasis was therefore on fitting other higher priority defensive systems. As a result of the recommendations made by the 2005 Board of Inquiry, Explosion Suppressant Foam will be fitted to some C-130 aircraft, concentrating on the aircraft that operate in the highest threat environment.
