Jul 06, Kathmandu - India's aviation regulator warned Air India in March that it had not replaced engine parts on its Airbus A320 aircraft on time and had falsified records to show compliance, a government memo showed.

Air India Express told Reuters it had acknowledged the error to Indian regulators and taken corrective and preventive measures. Reuters reported on Friday that the European Union agency would investigate the matter.

Air India has been under intense scrutiny since the crash of a Boeing Dreamliner in Ahmedabad in June, killing 241 people.

The investigation into what is believed to be the world's worst aviation disaster in a decade is still ongoing. The problem with the engine of the Air India Express Airbus was first reported on March 18, months before the crash.

However, the regulator has warned Air India this year for failing to check emergency slides on three Airbus aircraft and for serious violations of pilot duty hours in June.

Air India Express is a subsidiary of Tata Group-owned Air India. It has a fleet of over 115 aircraft and operates 500 daily flights to over 50 destinations.

The European Union Aviation Safety Agency issued an ‘airworthiness directive’ in 2023 to address a potentially unsafe condition in the CFM International LEAP-1A engine. It ordered the replacement of certain ‘components’ such as engine seals and rotating parts due to certain manufacturing defects found.
