Standard Services and Rates

NK’s service department rate for all repairs is $90 per hour, with a minimum $75 charge for any unit accepted for test and evaluation.

The standard rate for calibration of your GPS-NAV, L-NAV or S-NAV is $75. Calibration of your GPS-NAV Datalogger will include a Barograph Calibration Certificate in approved IGC format. Standard calibration turnaround for a pre-authorized and paid calibration is five business days or less. RUSH service (two day or better turnaround) is available for an additional fee of $25. If additional service is required at the time of calibration, total time and materials will be billed at the $90/hour rate, including the time spent on calibration.

NK is also pleased to offer firmware upgrades to the most current version available for GPS-NAV Dataloggers and L-NAV/S-NAV Glide Computers. Firmware upgrades are offered at a flat rate of $75.

Note that while NK is well stocked with components for the above products, there may be some repairs we are unable to perform because of part obsolescence. In this event, the product will be returned to you in the condition received and you will be billed for our test and evaluation time (minimum $75).

How to Return an Instrument

To return any instrument to NK for repair and provide payment information for your repair, you must complete an online Return Authorization on NK’s website. You will receive an instant RA # to mark on the outside of your package. This will speed your unit to Gary’s desk and provide him with all of the contact and service information he needs to get your service completed quickly. The Returns Center will also be regularly updated with the cost and status of your repair, allowing you to communicate with us 24 hours a day and keep the process moving quickly. You may also request a pre-paid UPS shipping label allowing you to send your unit in to NK at no cost. Return shipping will be billed based on the service selected.
