Aviation regulator DGCA issued a show-cause notice to SpiceJet on Wednesday, following eight technical malfunction incidents involving the airline’s planes in the past 18 days.

SpiceJet has failed to “establish safe, efficient and reliable air services” under the terms of the Aircraft Rules, 1937, the notice issued by the Directorate General of Civil Aviation (DGCA) stated. “The review (of the incidents) transpires that poor internal safety oversight and inadequate maintenance actions (as most of the incidents were related to either component failure or system-related failure) have resulted in degradation of the safety margins,” it added.
