PC-9M engine failure

Larbre34

The Irish Times has it that on Friday afternoon one of the PC-9s suffered an engine failure approx 30kms from Casement. The two man crew managed the incident and succeeded in gliding the aircraft to a landing at the Aerodrome.

Bravo Zulu to the two pilots on some fantastic airmanship.

glide ratio Pilatus PC-9?
or did the prevailing wind bring them home safe and sound?

Seems that airframe was due to go back to the factory for a scheduled maintenance period anyway, but Well done to the aircrew.

Depends on their altitude. 30km puts them at Bray head to the east or Enfield to the west, where their approach would be starting anyway.

Assuming it was 261 as per the photos in the RTE article - https://www.rte.ie/news/2021/0227/1199714-air-corps-incident/

Then it was over Kilcullen heading SSW, around 16000 feet and 200kts before turning around.

It was indeed FOX261.

Power turbine bearing failed and blew bits out and the engine feathered automatically upon loss of oil pressure. They did a very,very good job of getting it back in one piece.

Would the training pilot of taken control and landed the aircraft or would He/She said to the student let's see what your made off?

All emergencies default immediately to the instructor.

Does the AC have a spare PT6

Given the number of types they operate that use the PT6, I would be shocked if they didn't.

Would imagine different variants of the basic engine in the PC9, PC12 and AW139.. What level of commonality is there between variants would be the main issue, like could you have 1-2 PT6 engine sections as spares and just add on the gearbox/final drives as needed

PC9 & PC12 use the PT6-A. 139 uses the PT6-C.

Do the AC have approvals to split modules?

In any case, with an incident engine, the whole unit would likely need to go back to the engine shop.

we used to split modules on the Pt-6 in the King Air but I dont now if they do that now. If you have the right tools, it doesnt take long. Variants of the PT-6,like other engines,often different by the type and fitment of the accessories on the outside of the core engine. One subtype may have a pump that another doesnt or may have a pipe layout that another doesnt. It all depends on what airframe it is fitted to. They are generally very reliable and tough engines.
