Why Narco "factory direct" is
the best
value in avionics service today.
Simply put you just can't beat the service a manufacturer can provide. After all, nobody knows more about a Narco radio than Narco. We designed it, manufactured it. and thoroughly tested it before shipping it. And we stock every part, each meeting the specification of the original part. No substitutions. If you have a problem send your radio in directly for Factory Service.
Fast turnaround, as in "fast"
Narco promises a fast turnaround for a number of reasons of which not the least important is the size of our service department. Nobody employs as many expert technicians trained in Narco radios as Narco itself. Your radio will gather no dust waiting for service at Narco.
Rentals? Sure! But, if you want your own radio back in a real rush, there's Express Service. For an extra $100 Narco provides Express Service which is a custom solution to your individual problem.
We know Narco radios inside out
We also have their insides in stock all the time. That also contributes to a fast turnaround. And we've probably seen your problem before, so we spend less time in blind troubleshooting. Narco's technicians are the best in the business, and they are supported by the engineers who designed your radio and the manufacturing staff that built it. You won't find as much service firepower and expertise under one roof anywhere.
The Oldest Avionics Company In General Aviation
Narco Avionics is over 50 years old. As a result there are thousands of our radios in service that are well over 20 years old. As one might imagine it is extremely difficult for Narco to maintain parts vendors and field technical training for many of these older radios. Therefore, we feel our customers are best served by having these older products sent directly to the Narco factory for service.
While we have your radio, we update it with the significant modifications that have been incorporated since its manufacture. This brings new convenience to you, and extends the service life of your radio, too.
90 day service warranty.
Narco offers a 90 day limited warranty on most models of radios that it services. If your radio was manufactured within the last several years, it is probably covered by 90 day service warranty. Check with Narco Avionics for warranty coverage by specific model.
Special Support Programs
There's much more to Narco factory service than repairing a NAV/COM or transponder. Here are some special programs:
* Re-certification of ELT 910 with fresh NARCO battery pack.
* HT-800/830/870 repairs.
* COM 810/811 upgrade to COM 810+/811+
* Ground station certification.
Sooner or later, even a good radio is going to need some help.
Modern avionics are much, much more reliable than just a decade ago. The digital revolution in avionics that introduced conveniences such as the frequency storage/transfer feature found on Narco MK l2D+'s and the extensive use of surface mount technology in the NAV122/D also extended MTBFs significantly.
But it's a tough world out there on the other side of your instrument panel. Heat, vibration, high humidity, abuse, and salt-laden moisture are just some of the forces which can strain any brand of radio past the breaking point.
Although the cost of modern avionics, in real terms, has declined sharply over the past decade, the cost of field service has not That's why it makes sense to send your radio in for factory service when you suspect a complex problem. Send it yourself.
