Another Lycoming Crankshaft SB

Thankfully, no Aviat Huskies are affected. They are not the balanced
crankshaft models (which end in 6). Mine is 1996 anyway. This if going
to affect a lot of planes.

Has anybody else looked up your engine serial numbers on Lycomings latest
crankshaft service bulletin #566? This one adds about 1000 engines/cranks
to a previous SB for mainly 540cu in engines putting out over 300hp. Ours
ducked the bullet once again.

Details on Avweb and find the SB on Lycomings site. It sounds like they'll
make this one an AD soon.

Fortunately, my last OH was in 1987 :-)

There are also a few -360 (4 cyl) series engines affected, specifically
those with counterweighted cranks. The IO-360-C1C6 in our Arrow IV falls in
this category, and since we installed a factory reman last year I was very
worried until I looked up the list of affected SNs and crankshafts.
Fortunately, they used a refurbished, older crank (originally manufactured
before the March 1, 1999 cutoff) on our engine, so we dodged the bullet.

I got burned by this one- have to have the engine yanked on my Extra and
sent away for who knows how long.

A pretty long time, I'll wager. According to the "Dear Valued Lycoming
Customer" letter accompanying the SB, engines from planes used in Part 91
operations (including flight training) will be given LOWEST priority for
crankshaft replacement. So unless your Extra is government operated
(unlikely), used in Part 121 scheduled ops (exceedingly unlikely), or Part
135 commuter and/or charter ops (still pretty damn unlikely), I'm afraid you
are at the end of the line.

Lycoming will do the repair for free and will reimburse
removal/reinstallation and shipping costs, but they say nothing about the
cost and frustration of extended AOG time. Bummer.

There are about a dozen IO540C4B5's in the list and since one of ours was
overhauled in 2001, I had to contact Penn Yan to get the serial number of
the crank. No problem, it wasn't on the list.

Oh, man, Jim -- that really sucks.

On the other hand, if Lycoming is REALLY having trouble with crankshafts
failing, I would think that an Extra would be the LAST plane you would want
to fly with a weak link behind the propeller.

Please keep us posted. I'd be curious to know how Lycoming handles this.

Just checked yesterday. We dodged this bullet again, thanks to being able
to re-use our crankshaft during our overhaul in 2002.

For once, it's paid NOT to buy new.
