"All these are complicated procedures. It involves not only technology but also fiances. But these are being resolved. I will not say everything is in order but things are being worked out which happens in any product. There is distinct improvement, he said.
A team of 10 experts from Russia is currently in Pune, the Sukhoi-30 base, probing the crash that took place on October 14 near there with both the pilot seats ejecting without any command during landing.
The pilots were safe but the aircraft crashed about 20 kms short of the runway.
As standard operating procedure, the flying of the aircraft was suspended and a CoI ordered.
The sources said the Russian experts have claimed that the ejection of seats cannot take place automatically, a contention that is not being accepted by the Indian Air Force.
The grounded fleet represents almost a third of the country's fighter plane fleet.
IAF is already down to 34 combat squadrons, as against an authorised strength of 44. Each squadron has up to 18 fighter planes.
This was the fifth accident involving a SU-30 MKI since 2009 and the fleet has at least been grounded twice earlier.
