SpiceJet, which currently operates 11 MAX aircraft and has 144 pilots to fly them, said pilots have been limited to handling jets until undergoing retraining for the General Directorate of Civil Aviation (DGCA). Indian media reported that the restrictions were imposed after the discovery of defects in a simulator installation near Delhi, where they had received training for the Boeing aircraft.

The airline is Boeing’s largest customer in South Asia for MAX aircraft. “We are working closely with all parties involved, including our supplier and DGCA, to ensure that the maintenance and operation of this particular device complies with all regulatory requirements,” Boeing said in a statement. “We are committed to ensuring that our customers receive high quality simulation experiences in accordance with all regulations.” The pilots need to be successfully retrained and we will take strong action against those found responsible for the error, said Arun Kumar, director general of India’s DGCA air security watchdog. In August, the regulator approved the 737 MAX aircraft to fly after a regulatory landing of almost two and a half years after two deadly crashes in 2019.
