Engine failed in flight on Korean Air Airbus A220-300 on flight KE753 on 27 December

[Zenj]

A Korean Airlines Bombardier C-Series CS-300, registration HL8314 performing flight KE-753 from Busan (South Korea) to Nagoya (Japan) with 64 people on board, was climbing out of Busan when the crew stopped the climb at FL290 due to the failure of the left hand engine (PW1524). The aircraft returned to Busan for a safe landing about one hour after departure.

A replacement Boeing 737-900 registration HL7716 reached Nagoya with a delay of 2.5 hours.

This happened on 26th Dec 2018

KAL A220 fairly new engine for the LPT to disintegrate...PW1524G engine geared turbofan....

Ok, so we are looking from the rear , the last turbine stage and stators.
So, something let go in the hot section or maybe even in the compressor.
Interesting.

Not forward of the Burner, probably only a stage or two forward of the last stage turbine

Its the Low pressure turbine, what is also concerning is the fracture deformation /damage area noted below.

Needs a damper in the aircraft tail cone before it mimics the old B747 problem
