SAIB Reciprocating Engine - Cylinder Mounting Studs

[BigTex]

Guys, You see this new SAIB that came out today regarding the Lycoming cylinder mounting studs and recommendations on inspection?

 

Here's the link to it: http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgSAIB.nsf/0/8C01A9AAE28B401F86257CA50066C517?OpenDocument&Highlight=ne-14-13

I lubed the snot out of mine at install last year for that reason. Plus if you don't lube them, you will snag the oring that seals them anyway. Not an AD yet... It would be silly if it ever became an AD.

Well at Overhaul anyways...

Just read it a little while ago. Two foreign incidents of corrosion starting in plating pits. None in the USA per FAA and NTSB. Lycoming says follow their procedures, unless there is too much paint in the way, it won't be a problem. They also referenced proper use of torque wrenches.

 

I'm not worried, and not doing nothing.

Another CYA bulletin....nice to know if your doing an overhaul,  nothing to tear down your engine over

I had some that came loose on a O-320 I have in a experimental 25 hrs after a major OH.  Luckily I caught it and re-torqued them.
