Aviation regulator DGCA on Monday cracked down on airlines after "increased engineering related occurrences".
After frequent reports of engineering related occurrences in several airlines, DGCA has conducted several spot checks and advised that all aircraft at base and transit stations shall be released by certifying staff holding licence with appropriate authorisation by their organisation, said the aviation regulator in a statement.
The spot checks carried out by DGCA teams have indicated:
* Improper identification of cause of defect
* Increased trend of MEL (minimum equipment list) releases
* Non-availability of required certifying staff at short intervals for multiple scheduled arrivals/departures
