"The DGCA has been in dialogue with the manufacturers and the certifying regulatory authority for these engines (FAA, USA). It was also noted that FAA and its European counterpart EASA have not declared these engines as unsafe," the of Civil (DGCA) said in a statement.

"Based on these latest interactions, the DGCA will issue an additional directive relating to within a week to the airlines concerned. The situation is being continuously monitored by the DGCA as part of its safety oversight system."

The development comes after the Ministry of Civil and the DGCA held a meeting with IndiGo, GoAir, P&W and maker on Tuesday to review safety-related incidents with A320 Neo aircraft, powered by P&W.

The government has taken a serious note of the incidents with the aircraft's engines and called the meet to review the safety issues.

According to the DGCA, it has been noted that the "Inflight Shutdown" (IFSD) on account of NEO engines in has averaged 0.02 per 1,000 engine flight hours which is "considerably lower than the stringent global benchmark of 0.05 IFSD rates per 1,000 engine flight hours".

"So far in India, there have been 12 IFSDs since entry into service of NEO engines beginning March 2016."

Currently, there 97 Neo operating in the country which are powered by PW engines.

"Most of these IFSDs and other related incidents have happened due to failure of 'Number 3 Bearing' seal, failure of 'Knife Edge Seal', erosion of combustion chamber material, low pressure turbine rotor blades damage and issues relating to the 'Main Gear Box'," the statement said.

"... corrective action has been taken by P&W and the airlines in respect of all except issues relating to 'Main Gear Box' which is a recent phenomenon."

On its part, PW in a statement said: "appreciated the thoughtful exchange of information with the Ministry and the DGCA."

"All parties are now aligned on the status of the GTF programme in India, whose reliability has greatly improved over the last year. The GTF programme continues to be certified to the industry's highest safety standards."

The meeting follows last Thursday's incident with budget IndiGo, when its Kolkata-bound flight had to return to Chennai, and the said that it was the result of "technical caution" noted by the crew.
