Instrument Overhaul

[Matt M]

I have been chasing a static leak over the past month and determined my altimeter is leaking. It causes a 500+ fpm leak when you move the knob. My VSI also has a small 30-40 fpm leak. I want to send them out for overhaul while it goes into annual. I figure I might as well send the airspeed indicator as well since 2 of out of the 3 are going. The bezel is looking a little rough anyway. Has anyone used any of the instrument shops lately? I was looking at aircraft quality instruments, Rudy instruments, Berkshire, Kelly instrument. I am looking to do an overhaul vs. exchange. I can wait an extra week or two to save a few hundred bucks.

Back in the day you could just get the gasket replaced for about $50. Oh, the good old days.

Rather than a full overhaul you could ask for an Inspect and Repair as Necessary, (IRAN), that would save money.  They will only replace what is needed and bench check it saving money.  It would come with a yellow tag and 8130.

I used Rudy Instruments this past year to OH my altimeter.  Did great work and the price was reasonable.

I just sent my MAP/Fuel pressure gauge to Rudy Instruments 5 days ago. They called me today- overhaul finished. Paid $250 + shipping. That's over a holiday weekend.

I had Rudy overhaul my airspeed indicator 4 years ago and it leaked at pitot static check last week

sending it to AQI
