The OEM has offered certain modifications or technological improvements for implementation in the production of new aeroengines and during overhaul of engines. The modifications in the process of overhaul and manufacturing, proposed by Russian designers, have been implemented at HAL and OEM. The OEM has also advised certain precautions / predictive maintenance during exploitation of aeroengines which have been implemented by the Indian Air Force (IAF).
