Flights to Pakyong were operated under the Ude Desh Ka Aam Naagrik-Regional Connectivity Scheme (UDAN-RCS) policy. SpiceJet has around 30 Bombardier Dash 8 Q400 aircraft in its fleet, which are used for regional flights. After a SpiceJet Q400 aircraft coming from Goa made an emergency landing in Hyderabad on October 12 as extensive smoke was detected in the cabin, Civil Aviation Regulator DGCA (Directorate General of Civil Aviation) had directed SpiceJet to carry out analysis of engine oil samples from its Q400 fleet, and other inspections. DGCA ordered the budget carrier to inspect all operational Q400 aircraft engines within one week. In a statement issued today, it said it shall take all appropriate action to avert any untoward incident. The plane had landed safely, and passengers disembarked through the emergency exit. One passenger sustained minor injuries while disembarking from the aircraft, a DGCA official had said.
