Basically if it's electronic or is related to your instrument panel we'll do it!


For the most part we perform radio upgrades and repairs.

Our staff has considerable experience in installation of all types of state of the art avionic equipment including WAAS GPS systems, ADS-B systems, Autopilots, Primary Flight Displays, Skywatch/TCAD traffic systems, Engine Monitors, Strobe Systems, and much more.


IFR & VFR certifications as they are commonly called are more specifically 24 calendar checks done in accordance with FAR 91.411 & 91.413. Basically a VFR check consists of pulling a vacuum all the way up to the maximum expected altitude of the aircraft on the static system to check for leeks and verify the altitude output of the encoder matches the altimeter readout, and checking all parameters of the installed transponder (pulse with, spacing, frequency, sensitivity etc...).   IFR basically is the same with the addition of checking the altimeter against our master altimeter. More Info


    Rates for VFR & IFR:

    VFR transponder only: $75

    VFR: $125.00 (1 transponder with mode A & C, 1 encoder).

    IFR: $225.00 (1 transponder with mode A & C, 1 encoder, 1 altimeter)

    IFR: $300.00 (1 transponder with mode A & C & S, 1 encoder, 1 altimeter)

    Note: Mode S transponders require additional tests by specialized test equipment not found at all Repair Stations.


We can repair a wide array of avionics. For those units we do not repair or are more economical to send out we can troubleshoot which box to send out for repair and we have developed a relationship with many other shops so we can send your unit to an appropriate facility for an economical, reliable repair. Our Shop 


We also refurbish instrument panels. We have the capability to fabricate a completely new instrument panel for your aircraft. Our list of metal fabrication equipment includes CNC machining table, Bridgeport mill, metal lathe, Plasma cuter, welders to your basic break and sheer. Examples


After fabricating your panel will be Etched and Alodined by submersion to meet military specification MIL-C-5541 Class 1A & Class 3. Followed by the application of zinc chromate primer. Most places don't Alodine, most of those that do only mist Alodine, not submersion like we do here. Examples


Color is applied by mixed paint spraying (similar to automotive) or powder coating. Examples


We provide in house silk screening of placards directly to your panel with enamel ink. Examples


Luminescent panels can be fabricated from scratch or refurbished. Examples


Typical installation of passenger headset jack cups Examples
