 |
|
Warning,
I was working on a project to move stuff away from my cooling outlet and
observed that the four lower bolts holding my engine/landing gear mount on
were in excess of 1/2 a turn loose, as in easily turnable by finger.
These are cotter pinned. TTIS is 1240 on an RV-6, bolts last checked three
years ago and I delayed this because I got tired of ruining good cotter pins
when nothing was ever loose.
So it's back to ruining cotter pins,,, I pulled a few of the bolts out and
explored, but I didn't find any reason for why things got loose in the last
200 hours but didn't in the first 1000???
Also, there was a rant some time ago about AD's and how they do or don't
apply to experimentals. The recent ECI Titan cylinder AD 2008-19-05 pretty
much applies to any installation where that range of serial number cylinders
with a specific part number are in service. While they do use the verbiage
"Lycoming engines with these cylinders installed" the focus is clearly the
cylinders irrespective of what you choose to call your Lycoming parallel
valve engine. They also list cases of engines and aircraft where these might
be found but they do not limit the AD to these groups. The focus is on those
parts as installed in an airplane.
If you have Titan cylinders but not those in that range or part numbers you
might want to note this in the engine logs.
