As part of my walk around the other evening, I was shining my bright mag
light around the plane looking for problems. The hanger was a bit darker
than usual and so I had a really good look through the air screen right into
the air inlet of on my Pitts. The ram air box, has rubber seals all around
it, that are attached to a little box on the inside of the cowl. These
rubber seals all had red paint on them and some of that paint was starting
to crack/flake due to the flexing of the rubber. The result is that paint
flakes could easily come off the rubber seals and go straight into the
carburator. I presume the red paint is simply overspray from when the cowl
was painted, obviously nobody masked off the air inlet opening.

It took the cowl off and cleaned off all the paint on the rubber seals to
avoid ingesting paint flakes. I strongly recommend that anybody with a Pitts
check to make sure they do not have flaking paint inside that box, either on
the rubber or on the insides of the box itself.

I'm not sure what the engine would do if it ingested a quarter sized flake
of paint but I don't particularly want  to find out.

Cheers,

Peter Ashwood-Smith
