In addition to Qatar stopping delivery of the A320neo early this year, all operators of the PW1100G, geared turbofan equipped version have reported
major engine issues. Two of those, Spirit Airways in the United States, and Indigo in India have banned the aircraft from flying above 30,000 feet.
The latest problem appears to be extreme cold temperatures causing the bleed system to freeze shut. This weekend, Spirit had four of their A320neo
fleet grounded for unplanned engine changes, after getting Engine Oil Chip Detected warnings. Three of their aircraft are currently parked at
Dallas/Fort Worth airport, with two of them appearing to have windows and engines covered.
Spirit has started to charter out flights to Miami Air, to keep their full schedule flying. They originally planned to fly one day with Miami Air,
but it has been extended to at least two days, and possibly more as issues continue.
The DGCA has investigated engine problems on Indigo and Go Airlines and found three major problems. In coastal areas, they have seen a 25%
degradation in the combustion chamber, resulting in 13 premature removals of engines. They have found 28 premature removals due to the #3 bearing,
and one removal due to the main gearbox failure. Multiple carriers are requiring borescope inspections of the engines, every few weeks or sooner.
There have been several engine fires reported in flight by Indian operators as well.
