Remove Vacuum and add AV-30

I’m only going to replace the vacuum stuff and leave the rest. Apparently the AV-30 comes with STC so easy process I guess.

I was looking at the same deal in my Aircoupe. Remove 15 instruments & the vacuum system & replace with 4 instruments.

I was interested in the RC Allen 6 pack and heading indicator. Both are TSO’d but RC Allen hasn’t done STC’s. so my avionics shop nixed the deal, they won’t even attempt a 337 anymore.

The FAA here in Atlanta Ga has made the 337 process way harder to do. They said hire a DAR, or DER to skip the FAA 337 approval process.

They suggested the Garmin GI 275 pair (no steam gauges required). Even though the GI 275’s are slightly more expensive, they both are STC’d and listed on the AML. It’d be cheaper than the DAR/DER process and the GPS ties in via RS-232 to the heading indicator.

The 2 GI 275’s, an electronics international engine monitor, and a mounted clock, will give me IFR legal & less weight.

I am an A&P so I can perform and sign off much of this work myself.

Was what installed under 337? I’m not following.

The AV-30 and TailbeaconX package was like $600 more I think.

Was it installed under a 337? If so, can I get your N-number so I can get a copy of that 337. offsite This email address is being protected from spambots. You need JavaScript enabled to view it.
