Aircraft instrument services
Repair or replace: precision bench repair, overhaul and exchange for flight instruments and engine gauges, plus new instruments and avionics upgrades.
What we do
Our services
Every instrument starts with an evaluation on our bench in Show Low. We talk through what we found and recommend whether to repair or replace it, and you choose how to proceed.
-
Repair and overhaul
A repair finds the fault and fixes it. An overhaul restores the complete instrument: disassembled, cleaned, inspected, repaired as necessary, reassembled and tested. Engine gauges included.
-
Sales and upgrades
When replacing makes more sense, new instruments and complete avionics upgrades from Garmin, Mid-Continent, Sigma-Tek and other trusted manufacturers.
-
Exchange
Get the aircraft flying again without waiting on your own unit. Options depend on the instrument, so send the part number and we'll check.
-
Castleberry gyros
The Castleberry line is no longer in production. We repair and overhaul every model in its last brochure, and list each one's features.
