Airlines reported over 24,700 technical snags last year, with Jet Airways alone accounting for 9,689 of them, according to official data.
A total of 24,791 "defects/ snags" were reported by airlines in 2017, according to the data provided by the minister as part of a written reply.
"Snags have increased due to increase in number of aircraft in the airline and increased number of flight sectors," he said.
Out of last year's total, Jet Airways planes had 9,689 snags, followed by SpiceJet which reported 4,903 snags and Air India group at 4,563. GoAir reported 1,888 snags, AirAsia (1,367), Vistara (1,225), Blue Dart (793), IndiGo (340) and Zoom Air (23), the data showed.
"Technical snag (defect) means a condition existing in an aircraft (including its systems) or aircraft component arising from any cause other than damage, which would preclude it or another aircraft component from performing their intended functions or would reduce the expected service life of the aircraft or the aircraft component," Sinha said.
The Directorate General of Civil Aviation (DGCA) has regulations and procedures for monitoring snags encountered during aircraft operations. These include analysing engineering statistical reports and advising the aircraft operators to take corrective actions if there is any adverse trend and conducting spot checks.
