The move, which is subjected to DGCA approval, would allow Air India to fly these planes by another one-and half year than mandated operational life, aviation ministry sources said.
Significantly, one of Air India's pilots body, Indian Commercial Pilots Association (ICPA) had in March this year asked the Directorate General of Civil Aviation (DGCA) to ground these more than a two decades old classic A320s, citing safety issues.
The government-owned airline, however, can fly these planes beyond their operational life once the DGCA approves the same, they said.
The current operational life of an Airbus A320 stands at 48,000 flight cycles and 60,000 flight hours.

Of the 20 A320s in Air India's fleet of 103 planes, six are 26 years old, while seven planes are in service since 21 years. Besides, seven of these planes were manufactured in 1993 while one A320 belongs to 1990, according to the DGCA website.
Air India is already in the process of replacing about a third of its narrow-body (A320) planes which are more than 20 years old with new fuel efficient planes.
As part of the plan, the airline has already inducted three sharklets-equipped A320 ceo (current engine option) aircraft in the fleet, of the five such planes, for which it has tied up with the Chinese lessor China Aircraft Leasing Company.
The rest two planes are expected to be delivered by October.
