Something to Drool over.

The problem with the J is there’s 4 versions: with and without ram air, with and without landing light.

Moving forward slowly but parts are being manufactured and drawings made for the PMA and STC process. 
Thanks,

After the completed drawings/documents/etc are submitted to the FAA, how long does the PMA and STC process take?

There’s no telling with the FAA. Last PMA took me 2 years because they say they work safety items first.

 Cowling for the C and G’s still coming. 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).

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.

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.

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.

Interesting, I had not caught that! Thanks. I would love the wing lights in addition to my cowl light ..

With HID landing and taxi lights in both wings, you do not need a light in the cowling.

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.

Js got wing mounted lights starting #3154, of course there is also retrofits, my 78 included.

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.

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?

[Oscar Avalle]

How is the process coming along?
