Continental MSB just became an FAA AD

[Robert C.]

When I first read the letter from Frank, or rather the attached AD, that arrived today it scared the beegeebees out of me as it sounds like all the IO550s would now be affected regardless of age and operating hours.

After reading the AD 3 times I honed in on the statement that what mattered are the affected crankshaft number as reported in appendix I of MSB23-01A.

So I went to the Continental site and downloaded the MSB and found that only 3 aircraft with an IO550 (G)  are affected; but a lot of other IO550 models are mentioned so check yours! engine and crankshaft serial numbers for the IO550Gs are:

I0550G Engine Model Engine Serial No. Crankshaft Serial No.

1043460 N22GA016

1043941 N22FA013

1044491 N22CA232 

So I'm guessing that most Ovation owners with G model engines are in the clear. Lot's more IO360s though so check the list in the appendix carefully.

Fly safe

The AD is more restrictive than the SB.  We’ve finished our third and now have five more to do.
