| Subject: | Plane Power alternator |
Remember a few months ago when I asked what other's experience was
with PP alternators? At the time, I had installed a new PP alternator
that was very noisy. A couple of other PP owners also wrote to say
theirs was noisy also. My customer sent his alternator to PP to have
them check it. It came back saying it was in specs. It was still very
noisy. He installed an overhauled Kelly alternator that was quiet.
PP needs to tighten up their specs.

Geary, do you know a Gordon Harrison of Lancaster, CA? Seams I wound up
through an E-Bay purchase a few years ago of the Supplemental Flight Manu
al for his airplane. I did not notice the pages referencing his plane til
l today. The FAA registry shows he has owned this plane since 1978.
