Two Air India pilots were taken off flying duty and are facing an inquiry for skipping a breathalyser test, which detects the presence of alcohol on a person’s breath.

The commander and co-pilot of the Air India flight AI 3405 from Mumbai to Delhi on December 18 are among the country’s first pilots to face stringent action for skipping the safety measure to check if the flying crew is under the influence of alcohol.

The directorate of civil aviation (DGCA) issued a circular last month warning pilots of stringent action in case of violation of aviation rules that prohibit consumption of alcohol or sedatives 12 hours before reporting on duty. According to ministry of civil aviation records, 24 pilots across airlines have tested positive for alcohol consumption between January to November this year.

The Air India pilots, who did not take the breathalyser test, have been grounded for at least four weeks.

“This would be followed by a disciplinary action by Air India,” said a DGCA official requesting anonymity, as he is not authorised to talk to the media. An AI spokesperson refused to comment on the matter.

DGCA regional offices across the country have increased the number of random checks this month. “Considering the party season we have increased the number of checks,” added the DGCA official.

The DGCA’s strict approach is in line with the regulator’s plan to implement ‘zero tolerance’ policy towards pilots drunk on duty. Already, it is mandatory for Air India, Kingfisher and Jet Airways – domestic carriers operating international flights, to conduct alcohol testing before every flight. The rule is also applicable for pilots operating VIP flights and is likely to be made mandatory for domestic operations early next year.

DGCA is also planning severe punishment against defaulters by 2010.
