The Directorate General of Civil Aviation (DGCA) summoned officials of IndiGo and GoAir at its headquarters on Wednesday to discuss the airlines' long-running troubles with the Pratt & Whitney A320neo engines
"An urgent meeting with GoAir and IndiGo airlines has been called in the afternoon to review performance of Airbus Neo aircraft in their fleet," DGCA said in a tweet.
Later, the DGCA said Pratt and Whitney has been asked to ensure easy availability of spare engines to airlines and the aviation regulator will take the "harshest action" if the need arises.
About 40 percent of the domestic seat capacity of India is powered by neo engines and therefore, any knee-jerk reaction to completely shut their operations will have serious consequences, the regulator noted.
"The DGCA assures all its stakeholders that we are alive to the situation and will take the harshest action, should the need arise," it added.
"Manufacturer (Pratt and Whitney) has been directed to ensure more availability of spare engines for Indian operators to prevent grounding of aircraft due to removal of engines," the DGCA said in its statement.
While teething issues are bound to emerge in a new engine and the frequency of glitches has reduced from the earlier count, the meeting will largely discuss the problems which still remain and the timelines for their rectification.
Recently, engine maker Pratt & Whitney communicated to the regulator, airlines and the aircraft manufacturer Airbus that it will start delivering upgraded engines
from September, the timeline for which earlier was July. DGCA accepted the timeline but had warned Pratt & Whitney that it will not accept A320neos without upgraded engines from September 1.
Pratt & Whitney has been in the spotlight in the Indian aviation space since 2016 when India's largest airline IndiGo
started facing delivery delays in A320neo aircraft amid issues related to cooling down and start-up time of the engine, reliability, combustion chamber lining, oil seal and fan blades.
In fact, last year India's aviation regulator DGCA grounded as many as 14 Airbus A320neos following warning of a potential in-flight shutdown in a sub-category of its Pratt & Whitney engines.
