The preliminary examination of the engine parts showed that the standard of one ferrule initiated a disturbance in

 

the secondary air system used to cool the HP turbine.

After the release of the TC AD I contacted the FAA regarding the AD, I was told that they were a little slower in releasing the document but as of this afternoon I received the e-mail prior to it going on their site so here it is......

****, no worse that the 250-C18 "Blue Ribbon" engines prior to the installation of the two and a half bearing or the Jet Ranger "widow makers" tossing blades..........ah, those were the days. That will teach Bell to use a cheaper vendor for making wire for the TT straps, used 7 miles of wire and not 9. Now if only they kept the old orange garlock seals for the freewheel instead of speedi sleeves and the 406 seals for the forward cap assembly.

Canadian machines are not affected. It is about 40 machines in Europe only due to a bad batch of turbines.

Still requires a log entry even if not applicable...........
