According to India's autonomous auditing agency Comptroller and Auditor General (CAG), the Russian Sukhoi SU-30MKI jets suffer from poor serviceability.
The CAG report presented to Indian Parliament on Dec.18 notes that the operational readiness of the Russian jet was too low due to high rate of “Aircraft on Ground”, low serviceability and less achievement in flying hours. The unacceptable rate of AOG
(Aircraft on Ground) means that out of 210 SU-30MKI with the Indian Air Force, more than 120 jets are grounded for repairs.
This came ahead of India Prime Minister’s visit to Moscow scheduled for Dec.24-25.
