Domestic airlines reported 2,613 significant technical snags in their planes in the past five years, Union minister V.K. Singh told the Lok Sabha on Thursday.

The minister of state for civil aviation said the regulations required occurrences relating to system and component failure to be reported to the Directorate General of Civil Aviation (DGCA).

“These occurrences, based on their severity are investigated either by the concerned airlines under the supervision of the DGCA or by the DGCA under Rule 13(1) of the Aircraft (Investigation of Accidents and Incidents) Rules, 2017,” he said in a written reply.

Giving details, Singh said there were a total of 2,613 “significant technical snags” reported by various airlines in the country during the 2018-2022 period.

To a query on whether the use of old aircraft is the main reason for technical snags, he replied: “Aircraft is considered airworthy provided the maintenance is according to the approved schedule laid down by the manufacturer.... No aircraft can fly without having a valid airworthiness review certificate issued by the DGCA.”
