Again, a "Magnetic direction indicator" is all that is required not a whiskey compass. Heck, it is my understanding that some of the more advance airliners don't even have a shiskey compass any more.
Mel - are you kidding me? A DAR can require something that is not required through regulation simply because He/she thinks it is safer? I think I'd have to challenge any DAR directly on that count. Don't they have to inspect to some standard not opinion, especially in this case in which the FAR's are specific enough?

I stuck a whiskey compass on my glare shield with double sided tape and removed it as soon as the DAR was out of sight. The GRT magnetometer works just fine and the GPS course indicator is close enough to use in the unlikely event of magnetometer failure, and it is certainly more accurate/useable than a whiskey compass.
My RV-6 had an automotive compass suction-cupped to the windscreen (just) for it's inspection (1999).........
Velcro for me Ron. I have since passed the compass on to Doug Reeves for use in his RV-3.I stuck a whiskey compass on my glare shield with double sided tape and removed it as soon as the DAR was out of sight.

PS, Bill...which airliners do not have compasses in them? Personal curiosity! I figured the 787 and the new Sparky's (Airbus) are some of the most advanced out there....and they have a whisky compass in 'em.
Yes. I have no problem making my requirements known prior to inspection. There are very few things that I "add", like the firesleeve. And if the DAR is uncooperative, I sincerely believe that he will not receive many calls.Mel - do you, or would you, provide your personal requirements ahead of the inspection if the builder asked you in an attempt to avoid a denial of the airworthiness certificate? Do you think most DARs would be willing to do so?
I guess I wouldn't have a problem with a non-req fire-sleeve requirement as long as I knew it was expected and had time to install them prior to the inspection (although I planned on doing this anyway - this weekend in fact). This seems like a reasonable working relationship between builder and DAR. However, if the DAR shows up and says, "surprise, you should have installed a ballistic parachute cause I personally feel this is a safety of flight requirement" I might rather abruptly show him the way out of my hangar

I've been doing this for over 10 years and only had one person who didn't want to install firesleeve. After discussing the matter, I finally convinced him that it really should be there.
BTW, firesleeve IS required on all part 23 aircraft.
Mel,
Will you travel to Tyler for an inspection? Of course I have to build it first!
