India's aviation regulator has uncovered 51 safety violations at Air India during the past year, as part of its annual audit of the country's airlines.

Although unrelated to last month's Air India Boeing 787 crash that killed 260 people, the findings come amid renewed scrutiny of the airline after the tragedy.

Seven safety-related lapses were of the highest level, the auditors said, but did not provide details.

Air India said the airline was "fully transparent" during the Directorate General of Civil Aviation's (DGCA) July audit, which was part of routine checks to improve systems. Regular audits are standard for all airlines to assess and improve their processes, an airline spokesperson said.

"We acknowledge receipt of the findings and will submit our response to the regulator within the stipulated time frame, along with the details of the corrective actions taken," the spokesperson added
