Introduction
This Special Airworthiness Information Bulletin (SAIB) advises
registered owners and operators of the transmission of incorrect
information from the Honeywell NZ-2000 Primus Epic Flight Management
System (FMS) software having part number (P/N) VAR9XX, VAR10XX, or
VAR11XX and installed on Hawker Beechcraft Corporation (Type
Certificate Previously Held by Raytheon Aircraft Company) Model 4000
airplanes, Gulfstream Aerospace Corporation Model G-IV, GIV-X, and
GV-SP airplanes, Agusta AW-139 helicopters, and Cessna Aircraft Company
Model 680 airplanes.
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, D200909000044, dated October 15,
2009, to provide operators with guidelines for flight plan
modifications made on the ARRIVAL page, including a destination runway
change. This SAIB addresses the Primus Epic FMS because its software
was a derivative of the NZ-2000 FMS software. 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.
Recommendations
The FAA recommends that all owners and operators of Model 4000
airplanes, Model G-IV, GIV-X, and GV-SP airplanes, Agusta AW-139
helicopters, and Model 680 airplanes with NZ-2000 Primus Epic Flight
Management System software ensure their flight crews are familiar with
the procedures outlined in Honeywell Service Information Letter,
D200909000044, dated October 15, 2009.
