Thanks, David After the completed drawings/documents/etc are submitted to the FAA, how long does the PMA and STC process take? Quote Link to comment Share on other sites More sharing options...

There’s no telling with the FAA. Last PMA took me 2 years because they say they work safety items first. 1 Quote Link to comment Share on other sites More sharing options...

Landing light placement is an issue due to muffler location and clearance needed. Maybe look at non-traditional, flat LED arrays that give more packaging options? The requirements for landing lights are very loose (provides illumination, safe for operation). Quote Link to comment Share on other sites More sharing options...

I know of the with and without Ram Air. Mine will not have Ram Air. Was not aware of the no landing light. I don’t see that in the J IPC. I see two P/N of cowlings and the main difference being a larger oil service door on the last few years of the J. Thanks, David Quote Link to comment Share on other sites More sharing options...

Thanks, David I'm not aware of a no-landing light J config either... late models had extra wing lights, but I don't believe they eliminated the cowl light. I concur with the no ram air choice for the J (or vintage with J induction bits)... closing the hole in the cowl is the most tedious part of the removal, so leaving it out in your product is the right choice. 1 Quote Link to comment Share on other sites More sharing options...
Smiles201 Posted May 24, 2023 Report Share Posted May 24, 2023 This all reminds me of how long it takes to build a new cathedral. Even in this day and age it can take over 200 years. They are still working on The National Cathedral in Washington. Well worth the effort for something the next generation will appreciate.

I have a student with ‘90 J with landing lights in both wings and none in the cowling. this is a 28V J - and probably when they started that so i think tom is correct.Sent from my iPhone using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
KSMooniac Posted May 24, 2023 Report Share Posted May 24, 2023 Interesting, I had not caught that! Thanks. I would love the wing lights in addition to my cowl light .. Sent from my LM-V600 using Tapatalk Quote Link to comment Share on other sites More sharing options...
M20F-1968 Posted May 28, 2023 Report Share Posted May 28, 2023 With HID landing and taxi lights in both wings, you do not need a light in the cowling. John Breda Quote Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk For a data point, 1988 J 205 still had ram air and single light in cowl. I can confirm 1990 J had lights in wings.

catchman86 Posted February 23 Report Share Posted February 23 This is an incredibly exciting project, I spent a few hours reading over older posts and the work that has been accomplished so far. Hoping the PMA process is running smoothly and that the FAA isn't dragging this out. Quote Link to comment Share on other sites More sharing options...
Schllc Posted February 25 Report Share Posted February 25 I read it again recently to and had a question for @Sabremech. the ovation and acclaim both eliminated cowl flaps with the cowling design. Wouldn’t eliminating that complexity from the new cowl make it simpler to manufacture? Or does that make the FAA approval more difficult?
