New Delhi: Minister of State for Civil Aviation Jayant Sinha on Wednesday told the Rajya Sabha that a total of 24,791 defects/snags were reported by various airlines in 2017 in connection with the recent grounding of 11 Airbus 320 neo aircraft. Out of the 11 grounded planes, eight belonged to Indigo Airlines and three to Wadia group's Go Air.
Civil Aviation minister Jayant Sinha said that technical snags in airlines have gone up from 15,048 in 2014 to 21,500 in 2016.
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 a number of aircraft in the airline and increased number of flight sectors," Sinha said.
"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 added.
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.
