The aviation regulator also asked the no-frills airline to refund the money it charged from passengers of this delayed flight by selling food and beverages, instead of offering it free in accordance with the laid-down rules.
The Boeing 737-800 aircraft (VT-SGO), carrying 172 passengers including two infants, suffered engineering problems which led the pilots to abort take-off and return to the bay.
Another plane was pressed into service, replacing the 189-seater aircraft, to operate Flight SG-419 on June 16 after a delay of over four-and-a-half hours.
The warning flashed on the cockpit flight panel, indicating there would be no airconditioning through the entire flight after take-off. This led to the flight being aborted and the aircraft changed.
The DGCA probe found that during the entire delay at Mumbai, SpiceJet sold food and beverages in the aircraft in violation of rules - Civil Aviation Requirement (CAR) Section 3 which detail the facilities airlines should provide to passengers affected by the cancellation of or delay in flights for more than two hours.
The officials said the cabin crew as well as an airport manager informed DGCA in their statements that they were "not aware" of the provisions of the applicable CAR.
Following this finding, DGCA directed the airline to provide adequate training to the cabin crew and airport ground handling staff to make them aware of the provisions of CAR and follow them when such situations arose.
