India’s aviation regulator has issued a formal show cause notice to IndiGo’s CEO and COO following widespread flight disruptions affecting hundreds of passengers. The disruptions stem from the airline’s apparent failure to comply with new Flight Duty Time Limitation (FDTL) regulations governing crew rest and duty schedules. The notice, directed at executives personally rather than the company, carries potential penalties including license revocation and substantial fines. IndiGo reports restoring over 95% of operations by December 6, but the regulatory action underscores mounting compliance pressures in India’s commercial aviation sector.
