Cylinder Failure<br />
By Tom Rosen, Chairman, ABS Technical Committee<br />
The photos are of my #4 cylinder, an investment cast Millennium,<br />
that failed 50 hours after overhaul. If you look closely, you can<br />
see that the crack extends well to the left of the valve seat.<br />
The interesting part, and<br />
the reason I am sharing this<br />
with ABS members, is that I<br />
discovered the crack while<br />
complying with the Superior/<br />
Millennium Airworthiness<br />
Direc tive. The compression<br />
was 67/80, compared to the<br />
low 70s <strong>for</strong> the other five.<br />

Fuel Pump<br />
Replacement<br />
C J Aviation in Miami, Florida<br />
(305-378-1469) now has a PMA<br />
replacement electric boost pump<br />
to replace the Dukes pump in<br />
Bonanzas and Barons. The price<br />
is comparable <strong>for</strong> overhaul and<br />
only slightly higher <strong>for</strong> a new<br />
pump. They will take the old<br />
Dukes pump as an exchange <strong>for</strong><br />
the new PMA pump.<br />
Not remarkable at all. Visual<br />
inspection of the cylinder<br />
was normal. I never would<br />
have found the crack if my<br />
air compressor had been<br />
running, because I would<br />
not have heard the sound<br />
of air escaping through<br />
the crack. The soapy water<br />
test confirmed the leak on the left side of the head, way down against the<br />
#6 cylinder. There was almost no visible evidence of combustion products on<br />
the exterior of the cylinder head with the cylinder installed.<br />
As a result of this, I now always accomplish compression checks with the<br />
compressor turned off while I am taking the readings in a quiet hangar.<br />
