ALL aircraft with a ceiling above FL250 require the endorsement. The FARs define a "pressurized aircraft" as an aircraft with a ceiling higher than 25,000 ft. That means all T337s, period.

I'm still getting the misfiring...haven't fixed it yet. Kim, do you still have all that pressurize mag hardware?
