Installation requirements IFR GPS
I'm curious where the actual requirements are for installing an IFR
GPS. My local A&P says he knows an avionics guy who is semi-retired. I wonder if I could install a 430 in my KX-170B hole and have him sign it off. Would Garmin or any reseller sell me a 430 directly? For approach approval would the avionics guy just need to sign off the demo flight, what really is the reg for signing off an IFR GPS install? -Robert |

Installation requirements IFR GPS
Garmin will not sell directly.. only to their dealers..
IFR requirements include CDI indications to a standard CDI or HSI, cannot use the on screen indicator, also requires warning flags/lights within a certain "view pattern" of the pilot. Talk to a local Avionics intall shop.. also their is an AC on the FAA web on GPS installations for IFR/VFR use. BT "Robert M. Gary" wrote in message oups.com...

Installation requirements IFR GPS
You can easily install it and meet all the requirements. This
is a relatively simple job. There is lots of supporting data. Your success will depend on whether this guy has any standing with the FAA. You can find out. Have him prepare the 337 and flight manual ahead of time. Have him take it to the FAA avionics inspector. If the feds will field approve it, you are golden. Then the installation could begin and the money pump start. Bill Hale (who's FSDO says: Nothing but an ELT for you, sonny!) Robert M.

any compentant IA can do (or certify) the install, there are guidelines to be followed Just review the information in the Advisory Circular, get the paperwork done. BT "Robert M.

Installation requirements IFR GPS
My FSDO is requiring that 'they' inspect and sign off every IFR GPS
install, especially the antenna, before it is legal to fly the airplane... i.e. once the antenna is hung the airframe is no longer airworthy until FSDO approved... Backyard mechanics need not apply as the inspector is requiring a sign off by a 'licensed radio shop' before he will make the drive to look at the ship... I don't know if this is from OK City, or just a wild hair up this FSDO... I became aware of this when I picked up a ship that had a new install... It was parked on the ramp at the radio shop and the owner asked me to retrieve it while he was out of town... The line boys know me and knew I was taking it ... Anyway, the owner got a panic call from the radio shop that his ship was not legal to fly as the FSDO had not signed off yet, so I had to quietly fly it back that night and let it sit another week before the FSDO came around... For the nit pickers, don't bother hyperventilating - yes it was also not legal to fly back, but a phone conference with all involved decided this was the best way to handle it... denny |

In the last couple years the FAA has determined that GPS installs are
minor alterations. Perhaps your FSDO didn't get the memo.

Its one thing for the FSDO to say that the GPS may not be suitable for
IFR operations, but its totally another thing to say the airframe is unairworthly because you put an antenna on it. Just ridiculous. -Robert Denny wrote: My FSDO is requiring that 'they' inspect and sign off every IFR GPS install, especially the antenna, before it is legal to fly the airplane... i.e. once the antenna is hung the airframe is no longer airworthy until FSDO approved...

There's a lot of competition to be the worst FSDO.
So there's lots of variation. Standing is the key. If you don't have it, you will have a very hard time. That AC does make it sound like a minor alteration. But it doesn't say anything about the approved flight manual. It is written for people of standing. Still a 337 required around here. Remembering Rule #1 will help: "It doesn't have to make sense!" I once got a one shot STC for a homebuilt 3 axis autopilot. I'd hate to imagine what that would take now. It was hard 20 years ago.
