Russian manufacturers of the Sukhoi-30 MKI fighters have agreed to provide all assistance to the Indian Air Force for repair, overhaul and servicing of the multi-role aircraft, the entire fleet of which was grounded several months ago creating a near-crisis situation in the country.
The grounding of the entire SU-30 MKI fleet came after some of the planes experienced 'nicks' on the engine blades, which, the Russian experts said, were caused by foreign objects like stones or sand getting sucked inside the engine during take-offs or landings, according to a report in the premier journal 'Indian Defence Review' in its latest issue.
The journal quoted the aircraft's engine designer, Viktor Chepkin, as saying that though there was a "delay" in the delivery of special tools for independently repairing this damage, the engines were very user-friendly.
Mikhail A Pogosyan, General Director of Sukhoi Holding Company, said "our experts, who always work in very close cooperation with the IAF, have found out what caused the damage to the engine blades".
He said the logic of operation of a protective screen in the air intake of the engine has been explained to the Indian experts. "Besides, we have worked out certain measures to clear dents and scratches and all the necessary technical manuals and tools have already been supplied to the IAF"."
So, the engine problem can be considered to have been resolved", Pogosyan said.
