Mike Busch on the Continental Airworthiness Directive (MSB23-1) & Safe Cylinder Work

Mike Busch is arguably the best known Aircraft and Powerplant mechanic in general aviation.
Mike joins Jeff Simon on SocialFlight Live to talk about the new Continental Mandatory Service Bulletin (MSB23-1) & Airworthiness Directive , Safe Cylinder Removal and Installation & more.

Mike is legend. Been watching the Savvy aviation videos for years

We get so soon old and so late smart. 🤠

It is great to have Mike Busch explain the details of this situation. Nobody more qualified! Go Social Flight! - IO550 owner

Another must attend webinar! Thank you for having this on KZbin!

[@marcybuzanowicz7714]

Mike is the best!

Excellent explanation Mike 👌 👏

Can’t believe there not more views

I think the cyl. removal risks is a little overblown myself, don't be afraid to pull a jug. We used to operate a fleet of turbo'd Cessna cargo twins, no lube on threads, reuse old nuts, used crappy Chuck Ney rebuilt cyl's (because owner was cheap) and never had a problem. Key things are don't let cyl base wrench hit something solid while torquing nut, use correct sequence per book, check dry clearance on rockers ( must meet minimum), if cyl is 15k oversize must use larger piston and opposite cyl must also have larger piston. If nuts are not all torqued stud will snap which will lead to a possible cracked case and an engine removal :( ....Training new pilots always led to shock cooled cracked cyl's guaranteed. Training new mechanics to be vigilant is also key to long engine life to tbo and beyond.

My factory new O 470 R still in the crate at my mechanic's shop is subject to this AD. Fortunately, it passed inspection with no corrective action needed. I am not that happy that a cylinder had to be pulled and factory torque settings unloaded to do the inspection. But so it goes, I guess.

I was simultaneously relieved and a little concerned when Mike pointed out the need to install the circlips sharp-edge out. Not being an A&P technician and not having anything more than the Continental service bulletin as reference, I wondered if these were your normal, stamped clips with a crown on one face, and whether technicians would install these flat-side out, or whether it mattered in this instance. Thanks, Mike! True professional!

[@SocialFlight]

Standard A&P (and any mechanic) training is sharp edge out on any clip. These are normal stamped clips.

Wiggley counterweights that can fly off doesn't sound like a selling point 😮

[@SkyKing337]

So this must be the causal factor concerning so many Cirrus SR-22's with the Continental IO-550's, manufactured in the 2021 to 2023 arena, having so many engine fails and CAPS deployments. An expensive proposition after the crash...

[@toldt]

"It happened very rapidly," is a little misleading. The engine failures IIRC were months before the SB.

[@tomstrum6259]

What a Total crap design.....Automotive car & truck engine use compact, Reliable Harmonic Balancers to effectively Deal with crankshaft Harmonics over Wide rpm ranges.....Difficult to believe a Risky Idiot design using a calibrated "Loose pin" Circlip retainer would be used even in a Lawn mower engine !!

[@xenadu02]

It's more than harmonic balancing. Cars don't have a prop load hanging out off one end. The flywheel and transmission are much easier loads to deal with.
