    IAF clueless about its crashes; over 30% of crashes due to technical defects `unresolved’

    The Indian Air Force does not know what is causing a bulk of its aircraft to crash, inhibiting its ability to put in remedial actions and compromising the safety of its ageing fleet and pilots. A detailed study on flight crash records of the air force has found that over 40% crashes that are attributed to technical defect remain unresolved due to the lack of advanced air crash investigation technology, having an impact on flight safety.

    An audit of air crashes over a three years ending 2013 has revealed that out of the 37 total loss accidents that took place, almost half (18) were attributed to a technical fault in the aircraft. The rest were attributed to human failure. While the cases of human failure could be solved and remedial measures put in, the probe into over 30% crashes due to technical defects had to be closed without being resolved.

    The actual cause of a technical defect is crucial, as it affects the safety of an entire fleet, which if not resolved can cause accidents in the future. The crash of a Mi 17 chopper in Tawang in November 2010 that resulted in 12 deaths for example, has been classified as unresolved.

    While investigators found that one of the rotor blades of the chopper snapped off in flight, the cause of the breakage could not be established. In a July 2010, crash of a MiG 27 fighter that resulted in one casualty on the ground, the cause of the accident was found to be material failure of the turbine blade that had a dent on it.

    However, after an extensive investigation, the cause of the dent could not be found. In fact, a few months later in September another MiG 27 crashed and investigators could not get to the root of the problem.

    As part of the audit, the air force has admitted to the `uncertainty having implication on flight safety would continue to persist till such time the advanced technology was made available to investigators’. While technical investigations are difficult due to the lack of evidence on a downed aircraft, remedial measures are now being put in by the air force, including adding of an external technical expert from agencies like HAL to the board of inquiry into accidents.

    It is also now planning to ensure Flight Data Recorder (FDR) systems and other recording facilities on all its aircraft for proper forensics.

    Usual outcome with any foreign made hardware without warranties.

    the worst part is

    1. IAF is clueless - it is not bale to pinpoint the reasons of crash

    2. it does not allow anyone else - i.e. manufactureer, OEM (HAL) to be part of investigation team -

    3. Without pinpointing the real reason of crash - the OEM manufacturer cannot carry out any improvements - if needed - and so we may have repeat crashes due to same reasons and IAF will still not be able to find out the real reason
