The FAA is superseding an existing airworthiness directive (AD), which applies to all Honeywell FMSs served by Honeywell NZ-2000 navigation computers and IC-800 integrated avionics computers. That AD currently requires identifying affected computers by part number and software modification level and revising the Limitations section of applicable airplane flight manuals to provide procedures for retaining optimum position determination and intended navigation. This new AD requires upgrading new software, which terminates the existing requirements. This AD results from reports of in-flight unannunciated shifts of computed position in airplanes with the subject FMS computers. We are issuing this AD to prevent a shift in the FMS computed position, which could result in uncommanded deviations from the intended flight path of the airplane, and, if those deviations are undetected by the flight crew, compromised terrain/traffic avoidance.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 14 days after April 18, 2007 (the effective date of AD 2007-07-12): Determine if the installed NZ-2000 navigation computers and IC-800 or IC-800E integrated avionics computers serving FMSs have computer part numbers and software modification levels identified in Honeywell Technical Newsletter A23-6111-008, Revision 001, dated February 22, 2007. For purposes of this AD, airplanes with FMS computers having a part number and software modification level identified in the newsletter are “affected airplanes.”
For any affected airplane: Within 14 days after April 18, 2007, revise the Limitations section of the applicable AFM to incorporate the information included in Appendix A of Honeywell Technical Newsletter A23-6111-008, Revision 001, dated February 22, 2007. This may be done by inserting a copy of Appendix A of the newsletter into the AFM.
Within 12 months after the effective date of this AD, upgrade the applicable software as specified in Table 2 of this AD. After upgrading the applicable software, the requirements of paragraphs (f) and (g) of this AD are no longer necessary, and the AFM revision required by paragraph (g) of this AD may be removed.
| Upgrade new software in— | In accordance with the accomplishment instructions of— | For— |

| Honeywell Alert Service Bulletin 7018879-34-A6062, dated June 12, 2007 | The NAV computer identified in Honeywell Alert Service Bulletin 7018879-34-A6062, dated June 12, 2007. | |
| Honeywell Alert Service Bulletin 7018879-34-A6063, dated July 6, 2007 | The NAV computer identified in Honeywell Alert Service Bulletin 7018879-34-A6063, dated July 6, 2007. |
(i) Actions done before the effective date of this AD in accordance with Honeywell Service Bulletin 7017300-22-A6112, dated June 22, 2007, are acceptable for compliance with the requirements of paragraph (h)(1) of this AD.
