Airworthiness Directives; Honeywell Flight Management Systems 
(FMSs) Equipped With Honeywell NZ-2000 Navigation Computers and 
Honeywell IC-800 or IC-800E Integrated Avionics Computers; as Installed 
on Various Transport Category Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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.

DATES: This AD becomes effective May 14, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of May 14, 2009.
    On April 18, 2007 (72 FR 15818, April 3, 2007), the Director of the 
Federal Register approved the incorporation by reference of Honeywell 
Technical Newsletter A23-6111-008, Revision 001, dated February 22, 
2007.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2007-07-12, amendment 
39-15009 (72 FR 15818, April 3, 2007). The existing AD applies to all 
Honeywell FMSs served by Honeywell NZ-2000 navigation computers and IC-
800 integrated avionics computers. That NPRM was published in the 
Federal Register on August 21, 2008 (73 FR 49368). That NPRM proposed 
to retain the existing requirements of identifying affected airplanes 
by part numbers/modification levels and revising the Limitations 
section of the airplane flight manual. That NPRM also proposed to 
require uploading new software, which would terminate the existing 
requirements.

Actions Since NPRM Was Issued

    Since we issued the NPRM, Honeywell has published Alert Service 
Bulletin 7017300-22-A6112, Revision 001, dated February 7, 2008. In the 
NPRM, we referred to Honeywell Alert Service Bulletin 7017300-22-A6112, 
dated June 22, 2007, as the appropriate source of service information 
for accomplishing the proposed actions. The procedures in Revision 001 
of this service bulletin are essentially the same as those in the 
original issue of this service bulletin. Revision 001 of this service 
bulletin includes instructions to load software onboard as an 
alternative

[[Page 16122]]

to sending the unit to a service center to have the software loaded.
    Therefore, we have revised this AD to refer to Honeywell Alert 
Service Bulletin 7017300-22-A6112, Revision 001, dated February 7, 
2008, as the appropriate source of service information. We have also 
added a new paragraph (i) to this AD that specifies that actions done 
before the effective date of this AD in accordance with Honeywell Alert 
Service Bulletin 7017300-22-A6112, dated June 22, 2007, are acceptable 
for compliance with the requirements of this AD and re-identified 
subsequent paragraphs.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments that have been 
received on the NPRM.

Request To Remove References to Service Bulletin

    Honeywell requests that we remove the references to Honeywell 
Service Bulletin 7018879-34-6061, Revision 001, dated January 21, 2008, 
from the NPRM because the service modifications identified in this 
service bulletin are not affected by the identified unsafe condition 
and the modification works correctly.
    We agree that Honeywell Service Bulletin 7018879-34-6061, Revision 
001, dated January 21, 2008, is unnecessary. This service bulletin, 
which includes Modifications A and B, did not exhibit the FMS position 
jump problem that this AD addresses. This problem started when 
Modification C was incorporated into the affected units. Since 
Modifications A and B did not exhibit the FMS position jump problem, 
operators of these units are not required to incorporate the AFM 
revision procedures. Therefore, we have removed references to Honeywell 
Service Bulletin 7018879-34-6061, Revision 001, dated January 21, 2008, 
from this AD.

Request To Clarify Terminology

    Honeywell notes that the NPRM states that the new software should 
be ``uploaded.'' This term may cause some confusion as very few of the 
affected airplanes have the capability to field-load the software. 
Honeywell recommends replacing the term ``upload'' with ``upgrade.''
    We agree that this terminology may cause some confusion, and we 
have changed the ``upload'' terminology to ``upgrade'' throughout this 
AD.

Request To Change Contact Information of Manufacturer

    The manufacturer, Honeywell, has requested that we change the 
contact information for service information to Honeywell Technical 
Operations Center, 1944 East Sky Harbor Circle, Phoenix, Arizona 85034-
3442; telephone (U.S. and Canada) 800-601-3099; (international) 602-
365-3099; e-mail AeroTechSupport@Honeywell.com.
    We agree, and we have provided the specific contact information for 
the manufacturer as requested.

Conclusion

    We have carefully reviewed the available data, including the 
comments that have been received, and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We have determined that these changes will neither increase 
the economic burden on any operator nor increase the scope of the AD.

Costs of Compliance

    There are about 104 airplanes of the affected design in the 
worldwide fleet. The following table provides the estimated costs for 
U.S. operators to comply with this AD.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We have determined that this AD will not have federalism 
implications under Executive Order 13132. This AD will not have a 
substantial direct effect on the States, on the relationship between 
the national government and the States, or on the distribution of power 
and responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
