My 41 65CA has a 11AC cowling installed. Fits fine. Being as I've never been around the regular pre-war cowling, I'm not sure how it it was installed differently. I think that it was installed back in the 60"s.

My logbook in 1966 has an entry that cowling and exhaust system changed to 7AC per 337 dated and approved by FAA on 6-20-66
I can't find the 337 in my paperwork and I'm looking for FAA DVD that has the a/c records of 337's.

The '41 65CA cowling is basically what became the 11AC cowling. In fact the '41 Super Chief is different than the '38 thru '40 Chiefs.

Rob
I finally found a mircofich reader and was able to access the 337's for my 65CA
I found the 337 for switching the cowling to a 11AC cowling. If you want a copy of the 337 for refrence, I will try to find a unit that can copy the 337. I'm going to order a new DVD from the FAA; which my other a/c use, and it is much easier to print.
The comments said that the cross over exhaust was replaced, the carb intake was changed and the baffling was modified for the 11AC cowling.

Richard,

Was going to suggest doing the CD route. I have not seen a 'fiche reader in eons and trying to find one that prints would be really difficult. You should have the CD in a week to 10 days.

If you give your "N" number to Rob, he can simply order the CD for your airplane (costs under $10) and that way he will have a copy of the 337 on it direct from the FAA.

Public Libraries usually have phish readers and phish printers.

FAA CD cost is $10--just ordered one. Go to FAA.gov and click on registration and you will see where you can order records--and pay by credit card..
