ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Honeywell FMSs served by Honeywell NZ–2000 navigation computers and IC– 800 integrated avionics computers. The existing 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 proposed AD would require uploading new software, which would terminate the existing requirements. This proposed AD results from reports of in-flight unannunciated shifts of computed position in airplanes with the subject FMS computers. We are proposing 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: We must receive comments on this proposed AD by October 6, 2008.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. sroberts on PROD1PC70 with PROPOSALS Discussion On March 23, 2007, we issued AD 2007–07–12, amendment 39–15009 (72 FR 15818, April 3, 2007), for all Honeywell flight management systems (FMSs) served by Honeywell NZ–2000 navigation computers and IC–800 VerDate Aug<31>2005 17:27 Aug 20, 2008 Jkt 214001 integrated avionics computers. That AD requires identifying affected computers by part number and software modification level and revising the Limitations section of applicable airplane flight manuals (AFM) to provide procedures for retaining optimum position determination and intended navigation. That AD resulted from reports of in-flight unannunciated shifts of computed position in airplanes with the subject FMS computers. We issued that 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. Actions Since Existing AD Was Issued The preamble to AD 2007–07–12 specified that we considered the requirements ‘‘interim action’’ and that the manufacturer was developing a modification to address the unsafe condition. That AD explained that we might consider further rulemaking if a modification is developed, approved, and available. The manufacturer now has developed such a modification, and we have determined that further rulemaking is indeed necessary; this proposed AD follows from that determination. Relevant Service Information We have reviewed Honeywell Alert Service Bulletin 7017300–22–A6112, dated June 22, 2007. This service bulletin describes procedures for uploading new software in a certain IC– 800 or IC–800E integrated avionic computer (IAC), as applicable. We also have reviewed Honeywell Alert Service Bulletins 7018879–34–A6060, Revision 001, dated January 21, 2008; 7018879– 34–6061, Revision 001, dated January 21, 2008; 7018879–34–A6062, dated June 12, 2007; and 7018879–34–A6063, dated July 6, 2007. These service bulletins describe procedures for uploading new software in certain NZ– 2000 navigation computers (NAV computer). Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 49369 condition that is likely to develop on other products of the same type design. For this reason, we are proposing this AD, which would supersede AD 2007– 07–12 and would retain the requirements of the existing AD. This proposed AD would require accomplishing the actions specified in service bulletins described previously, which would constitute terminating action for the retained requirements. Differences Between Proposed Rule and Service Bulletins Although the service bulletins recommend installing the new software ‘‘as manpower and material are available,’’ we have determined that this imprecise compliance time would not address the identified unsafe condition in a timely manner. In developing an appropriate compliance time for this AD, we considered not only the manufacturer’s recommendation, but the degree of urgency associated with addressing the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to upload the new software. In light of all of these factors, we find a compliance time of 12 months for completing the proposed actions to be warranted, in that it represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. Change to Existing AD We find that Honeywell Model IC– 800E IAC was not specifically identified by model name in the applicability of AD 2007–07–12. However, that IAC was identified by manufacturer’s part number 7017300–56023 in the effectivity listing of Honeywell Technical Newsletter A23–6111–008, Revision 001, dated February 22, 2007, which was referenced in AD 2007–07– 12 as the appropriate source of service information for accomplishing the required actions. Therefore, we have revised the applicability of this proposed AD to specifically reference Model IC–800E IAC in addition to Model IC–800 IAC, where appropriate. 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 proposed AD. E:\FR\FM\21AUP1.SGM 21AUP1 49370 Federal Register / Vol. 73, No. 163 / Thursday, August 21, 2008 / Proposed Rules ESTIMATED COSTS Action Average labor rate per hour Work hour AFM revision (required by AD 2007–07–12) ....................... Terminating action (new proposed action) .......................... 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the 1 1 Number of U.S.-registered airplanes Cost per airplane $80 80 $80 80 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 the proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the 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 proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 77 77 Fleet cost $6,160 6,160 PART 39—AIRWORTHINESS DIRECTIVES 1.

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: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede an existing airworthiness 
directive (AD) that applies to all Honeywell FMSs served by Honeywell 
NZ-2000 navigation computers and IC-800 integrated avionics computers. 
The existing 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 proposed AD would require uploading new software, 
which would terminate the existing requirements. This proposed AD 
results from reports of in-flight unannunciated shifts of computed 
position in airplanes with the subject FMS computers. We are proposing 
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: We must receive comments on this proposed AD by October 6, 2008.

Discussion

    On March 23, 2007, we issued AD 2007-07-12, amendment 39-15009 (72 
FR 15818, April 3, 2007), for all Honeywell flight management systems 
(FMSs) served by Honeywell NZ-2000 navigation computers and IC-800 
integrated avionics computers. That AD requires identifying affected 
computers by part number and software modification level and revising 
the Limitations section of applicable airplane flight manuals (AFM) to 
provide procedures for retaining optimum position determination and 
intended navigation. That AD resulted from reports of in-flight 
unannunciated shifts of computed position in airplanes with the subject 
FMS computers. We issued that 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.

Actions Since Existing AD Was Issued

    The preamble to AD 2007-07-12 specified that we considered the 
requirements ``interim action'' and that the manufacturer was 
developing a modification to address the unsafe condition. That AD 
explained that we might consider further rulemaking if a modification 
is developed, approved, and available. The manufacturer now has 
developed such a modification, and we have determined that further 
rulemaking is indeed necessary; this proposed AD follows from that 
determination.

Relevant Service Information

    We have reviewed Honeywell Alert Service Bulletin 7017300-22-A6112, 
dated June 22, 2007. This service bulletin describes procedures for 
uploading new software in a certain IC-800 or IC-800E integrated 
avionic computer (IAC), as applicable. We also have reviewed Honeywell 
Alert Service Bulletins 7018879-34-A6060, Revision 001, dated January 
21, 2008; 7018879-34-6061, Revision 001, dated January 21, 2008; 
7018879-34-A6062, dated June 12, 2007; and 7018879-34-A6063, dated July 
6, 2007. These service bulletins describe procedures for uploading new 
software in certain NZ-2000 navigation computers (NAV computer). 
Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to develop on other products of the 
same type design. For this reason, we are proposing this AD, which 
would supersede AD 2007-07-12 and would retain the requirements of the 
existing AD. This proposed AD would require accomplishing the actions 
specified in service bulletins described previously, which would 
constitute terminating action for the retained requirements.

Differences Between Proposed Rule and Service Bulletins

    Although the service bulletins recommend installing the new 
software ``as manpower and material are available,'' we have determined 
that this imprecise compliance time would not address the identified 
unsafe condition in a timely manner. In developing an appropriate 
compliance time for this AD, we considered not only the manufacturer's 
recommendation, but the degree of urgency associated with addressing 
the subject unsafe condition, the average utilization of the affected 
fleet, and the time necessary to upload the new software. In light of 
all of these factors, we find a compliance time of 12 months for 
completing the proposed actions to be warranted, in that it represents 
an appropriate interval of time for affected airplanes to continue to 
operate without compromising safety.

Change to Existing AD

    We find that Honeywell Model IC-800E IAC was not specifically 
identified by model name in the applicability of AD 2007-07-12. 
However, that IAC was identified by manufacturer's part number 7017300-
56023 in the effectivity listing of Honeywell Technical Newsletter A23-
6111-008, Revision 001, dated February 22, 2007, which was referenced 
in AD 2007-07-12 as the appropriate source of service information for 
accomplishing the required actions. Therefore, we have revised the 
applicability of this proposed AD to specifically reference Model IC-
800E IAC in addition to Model IC-800 IAC, where appropriate.

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 proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39

Unsafe Condition

    (d) This AD results from in-flight unannunciated shifts of 
computed position in airplanes with the subject flight management 
system (FMS) computers identified in paragraph (c) of this AD. 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.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Requirements of AD 2007-07-12

Identification of Part Number/Modification Level

    (f) 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.''

Revision of Airplane Flight Manual (AFM)

    (g) For any affected airplane: Within 14 days after April 18,
