In case the Saturday news disappears before someone gets to it, the
following is a copy of the Crossbow letter:
<<<<<<<<<<<<<<<<<<<<<<<<<
Dear Crossbow Customers,
Crossbow fully understands that it is
extremely unfortunate and unacceptable that customers have experienced
intermittent startup, GPS, and EMI problems when the Crossbow NAV425EX AHRS is
used in conjunction with the Direct-To Avionics EFIS products. At Crossbow, we
are committed to providing safe, reliable products which live up to our
customers’ expectations. Our customers’ safety is always our top priority and as
pilots we understand that our products play a crucial role in safe flight. As
stated in our previous service letters, the NAV425EX should only be used in
VFR/day conditions until an upgraded version is released.
Crossbow has addressed the problems reported in connection with the NAV425EX
AHRS as stated in our service letters posted on our website. We have a solution
that is in validation testing now. The intermittent nature of the reported
problems has made them difficult to observe, solve and validate in our
laboratory. Status and details of the solutions are and will continue to be
available on our website. The solution process has been longer than
either Crossbow, or Direct-To Avionics desired for our NAV425EX customers. We
deeply regret the delay and inconvenience we have caused our customers and
partners.
Direct-To Avionics has ended their business relationship with Crossbow.
Crossbow is committed to our AHRS customers and their flight safety and
therefore will directly support all customers that purchased NAV425EX from
Direct-To Avionics by directly providing a software and hardware upgrade at the
completion of our validation testing.
The NAV425EX is a modified low cost version of our standard NAV420 catalog
product and is built to a Direct-To Avionics specification. All standard NAV420
products will also be eligible for upgrade to the latest released hardware and
software configuration upon completion of validation testing.
The upgrade program will be operated directly by Crossbow to ensure complete
satisfaction for NAV425EX AHRS customers. Status of the upgrade program and the
procedure for completing the upgrade will be posted at www.xbow.com
Crossbow has asked affected customers to contact customer service at
1-800-XBOWTEC, or fill out a customer survey on their website at www.xbow.com/support,
or contact Dean Johnson, Vice President, directly by email djohnson@xbow.com or
phone @ 408.965.3348.
