TRANSPONDER RECERTIFICATION'S INCLUDE A FRESH ALIGNMENT AND LOGBOOK ENTRY FOR $195 PLUS SHIPPING

 

 

 

24 month transponder recertification with log book sticker

The first paragraph of FAR 43 APX F (Transponder testing standards) states "The tests required by FAR 91.413 may be performed as either a ramp or a bench test". Bench testing and alignment has advantages over ramp test. For one thing, if you have an older unit as shown below, your transponder was designed so that various "stages" can be to be tuned. This helps to compensate for ageing components that slowly change value. Also, this service is generally more convenient and a better value than other alternatives.

Should you elect this service we will need your N number and make/model as per FAA for our workorder.           
                            



Our easy to use INTERACTIVE HELP section may help you localize the problem.  It's even possible the trouble is in the antenna or power source and your mechanic could help.


If you do not see your transponder below please check back. We will be adding more to our capabilities list soon.
