Pulling up Hindustan Aeronautics Limited for an inordinate delay of 14 years in the development and supply of a trainer aircraft, the CAG has observed that the time overrun has affected the Stage-II training of IAF pilots.
In its latest audit report tabled in Parliament, the Comptroller and Auditor General also noted that advances to the tune of Rs 2,953.88 crore released to HAL against the contract remains unutilised.
Besides, the aircraft under development would be heavier as compared to Indian Air Force parameters and that may affect training-related performance, the report observed.
Conclusion of the contract for series production of the trainer aircraft even before IOC/FOC of prototypes resulted in advances of Rs 2,953.88 crore lying unutilised, the CAG said.
At the time of submitting the proposal to the Cabinet Committee on Security for procurement of 12 Intermediate Jet Trainer-Limited Series Production aircraft, the defence ministry had stated that the experience gained from the operational exploitation of the machines would be conveyed to HAL for incorporation of necessary modifications on the subsequent series production.
Air Force had also clarified to HAL in September, 2007, that the order for series production would be placed after the induction of the 12 IJT-LSP aircraft, the report said.
"However, we observed that against their own commitment, Air HQ had initiated a proposal for supply of 73 SP-IJT aircraft from HAL even before completion of IOC and Final Operational Clearance of prototype aircraft and delivery of any of the 12 IJT-LSP
