Mags at Altitude

[kevin]

Larry,

Not all P337s or T337s have pressurized mags. Rileys all do, but other than that, I would say most do not. If you do proper magneto maintenance at every annual, you don't need pressurized mags, although I think they are a good idea.

The source of the pressurization is the turbo, so on your bird, you can't get pressurized mags anyway.

I flew my '65 337 as high as 16,000 feet without a problem.

Rock on.
