Air India has been issued an official warning by an aviation supervisor to violating security rules after the three planes were set up despite being delayed for essential controls on emergency equipment, according to a report. India’s General Directorate of Civil Aviation (DGCA) found during controls in May in May that mandatory inspections for urgent rescue slides in three of the airline airbus planes were delayed. Inspection of an Airbus A320 was delayed for more than a month before it ended on May 15 – flew to international destinations during the delay, according to Reuters. An A319 used domestically had delayed checks for three months, while a third plane had a two-day delay. In one of the incidents, the error was discovered when an “inadvertent engineer inadvertently decided a rescue slide during maintenance,” the report claimed. Controls on escaping lands are “a very serious issue. In the event of an accident, if they do not open, this can lead to serious injuries,” Reuters aviation expert Vibhuti Singh told. Air India accepted the findings in a statement and said it was “accelerating” its verification of its maintenance data. The findings come just a week after an Air India Boeing 787 Dreamliner crashed only a few moments after the rise, killing at least 270 people in one of the deadliest aviation disasters in decades. Warning notifications and the investigation report were not related to the clash.
