Terming the recent spate of Mirage 2000 fighter crashes as "surprising and alarming", the Air Force today said that IAF's frontline fleet had recently been put to a strenous checks and some of the components of the accident-involved aircraft were being examined.
Giving details of the last night's crash of the Mirage fighter near the Gwalior Airbase, Air Marshal S K Malik, Vice Chief of the Air Staff said preliminary reports indicated that the pilot could have orientation problems leading to the crash.
He said the flight data recorder of the aircraft had been recovered and would be thoroughly examined by the court of inquiry instituted to probe the crash.
The Vice Chief said premlinary reports of earlier two crashes last month - one near Gwalior and other during air show at Mauritius - had indicated technical problems, so some of the components like blades had been sent for examination to the National Metallurgical Labortary in Jamshedpur.
"One the report expected within a week is received, it would be sent for expert study by the French manufacturers", Malik said.
The Vice Chief said the recent crashes were surprising as the Mirage of all fighters in the inventory of IAF had the cleanest safety record, with only six aircraft involved in accidents since their induction in 1987.
