First, the good news: The DER has finally accepted my drawings and the stress analysis is done. It looks like the drawings and Project Plan and Test Plan and PMA paperwork and hell I forget what else, will be submitted within a few weeks. Finally. The bad news: I was going to just include all of the planes built under the AA5, AA5A, AA5B, and AG5B type certificate. Then, one of the three DERs working on the project said, "I was reading the TCDS (Type Certificate Data Sheet) and it says the AA5 and AA5A have an O320. Do you have to change anything to make your cowling work on these planes?" Ah, well, (dancing as best I could) . . . . Probably. "Then, you'll have to do those under a different STC, but, now it''l be easier because you already know what to do." Bad news continued. "Question." the DER says. "You were telling us that the AG5B has a carbon fiber cowling. Are there any other differences between the AA5B and the AG5B?" Ah, well, the inlet air induction is different. I went on to explain how American General screwed up the inlet and airbox design. "So, then, it doesn't use the same airbox as used on an AA5B Tiger?" I told them, "No. ... BUT.... I could use the AA5B airbox, but I'd have to get used ones or have them made." So, unless the AG5B drivers that want my cowling can find an AA5B airbox, they will have to wait until I get a NEW design approved with a carb air inlet that can use the AG5B airboxes (2, yes, they have two.) So, the bill to finish the project is a tad under $10,000. Any more takers on a PRE-certification sales price of $6,000? I would imagine the finished cowling will be around $8,000. I'm going to try and hold the price down.

This might raise some other issues like the throttle cable length and location coming out of the firewall. Does your engine induction air come off the back of cylinder #3 as it does on the AA5B?
