Honeywell NZ-2000 and FMZ-2000/IC-615/IC- 800/IC-1080 Primus Epic Flight Management System SAIB NM-10-13

This Special Airworthiness Information Bulletin (SAIB) advises registered owners and operators of the transmission of incorrect information from the Honeywell NZ-2000 and FMZ-2000/IC-615/IC-
800/IC-1080 Primus Epic Flight Management System (FMS) software.

[P/N and Aircraft listed in SAIB]

Background
During an RNAV approach, an airplane programmed with NZ-2000 FMS software (version 5.2) flew the WATTS THREE ARRIVAL (RNAV) Standard Terminal Arrival Route (STAR). A different runway was selected in the FMS during the STAR, and resulted in the FMS navigating the airplane toward the initial STAR waypoint instead of the next sequential STAR waypoint. As a result of this
incident, Honeywell International Inc. issued Service Information Letter, D200908000055, dated October 15, 2009, to provide operators with guidelines for flight plan modifications made on the
ARRIVAL page, including a destination runway change. At this time, the airworthiness concern is not an unsafe condition that would warrant airworthiness directive (AD) action under Title 14 of the
Code of Federal Aviation Regulations (14 CFR) part 39.
