Earlier in the day, the Directorate General of Civil Aviation (DGCA) had called an urgent meeting with officials of no-frills carriers IndiGo and GoAir to take stock of the glitches faced by P&W engines.
...“It is true that there have been cases of air turn back, in-flight shutdown or engine vibrations beyond the prescribed limits, but with strong mitigation measures in place and strict adherence to SOPs (standard operating procedures) by the airlines, the problem is being contained,"
It sounds like the mitigation actions are working, but there are a number of issues.
The DGCA further said major issues ever since the induction of P&W engine-powered A320neo aircraft included “combustion chamber distress (Block B and Block C)", “N2 transient vibration", “low-pressure turbine (LPT) failure", “gear box failure" and “#3 Bearing Pre Mod and Post Mod failures".
Grounding 40% of India’s domestic capacity after the collapse of Jet Airways would have serious ramifications. IndiGo has almost 100 A320neos in service. It is good to see the airlines and regulatory agencies working together to prevent the need for grounding airplanes.
Has there been any word on how many engines have been changed? More than 30 events in India is significant.
