NEW DELHI - India's civil aviation watchdog -- Directorate General of Civil Aviation (DGCA) -- has directed Air India to immediately remove three of its senior officials, including a divisional vice-president, from all responsibilities related to flight crew scheduling and rostering.

The DGCA, in its order issued on Friday, has asked the airline to initiate internal disciplinary proceedings against these officials without delay.

The regulator noted that the three officials -- a divisional vice-president, a chief manager of crew scheduling and one planning executive -- have been involved in serious and repeated lapses, including "unauthorized and non-compliant crew pairings, violation of mandatory licensing and recency norms and systemic failures in scheduling protocol and oversight".

The DGCA also warned Air India that future violations in crew scheduling will invite "strict action", including license suspension and operational restrictions.

Meanwhile, Air India Saturday said it has acknowledged the DGCA directive and implemented the order.
