Overview
- The A320, registered VT-TQN, flew eight revenue sectors on November 24–25 before Air India notified the regulator on November 26.
- DGCA ordered the jet grounded, opened a formal investigation, and de-rostered personnel linked to the lapse.
- Air India suspended staff, called the incident “regrettable,” and launched an internal probe to identify system gaps and corrective measures.
- The lapse traces to the Vistara–Air India merger transition in which DGCA handled the first ARC renewals: 69 aircraft were cleared, while this jet’s ARC expired during an engine change and it was wrongly returned to service.
- An ARC is an annual validation of an aircraft’s Certificate of Airworthiness; renewal for VT-TQN is in progress and regulatory enforcement decisions are pending.
