EASA Distributes FAA Recommendation: Special Airworthiness Information Bulletin
FAA Aviation Safety
SPECIAL AIRWORTHINESS INFORMATION BULLETIN
SAIB: NM-10-12
SUBJ: Navigation: Flight Management System Date: January 7, 2009
This is information only. Recommendations aren’t mandatory.
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.
