Terry,

Thanks for calling.

In a nutshell, The Gulf Coast wing of the CAF is in a bind and they need to get their plane flying for this air show season as soon as feasible (and legal).

Attached are:
1. photo of plane
2. Drawing of exhaust mod on #1 and #4 (outboard) engines.
3. Memo form Mr. Jimmie Stahl, the Houston FSDO maintenance inspector that has taken ownership of this issue.
4. Business cards of Mr. Chuck Conway, lead mechanic of the CAF wing.

I know details are lost in second and third hand tellings, but I will explain it how I understand it and let you work your magic if you can.
