Airworthiness Directives; Aircraft Equipped With Garmin AT,
Apollo GX Series Global Positioning System (GPS) Navigation Units With
Software Versions 3.0 through 3.4 Inclusive
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to aircraft equipped with Garmin AT, Apollo GX series GPS
navigation units with software versions 3.0 through 3.4 inclusive, that
requires modification and testing of the software for Apollo GX50/55/
60/65 TSO-C129a GPS navigation units; and
[[Page 38828]]
reidentification of the part. This action is necessary to prevent the
GPS navigation unit, under certain conditions, from providing erroneous
cross-deviation information, which could result in the aircraft
deviating from its intended course for a brief period of time.
Erroneous information may also place an excessive workload on the
flightcrew while they monitor other available navigation data to avoid
deviating off course. This action is intended to address the identified
unsafe condition.
DATES: Effective August 3, 2004.
The incorporation by reference of a certain publication listed in
the regulations is approved by the Director of the Federal Register as
of August 3, 2004.
ADDRESSES: The service information referenced in this AD may be
obtained from Garmin AT, 2345 Turner Road Southeast, Salem, Oregon
97302. This information may be examined at the Federal Aviation
Administration (FAA), Transport Airplane Directorate, Rules Docket,
1601 Lind Avenue, SW., Renton, Washington; or at the National Archives
and Records Administration (NARA). For information on the availability

FOR FURTHER INFORMATION CONTACT: Walter Cameron, Aerospace Engineer,
Systems and Equipment Branch, ANM-130S, FAA, Seattle Aircraft
Certification Office, 1601 Lind Avenue, SW., Renton, Washington 98055-

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to aircraft equipped with Garmin AT,
Apollo GX series GPS navigation units with software versions 3.0
through 3.4 inclusive was published in the Federal Register on April 1,
2004 (69 FR 17076). That action proposed to require modification and
testing of the software for Apollo GX50/55/60/65 TSO-C129a GPS
navigation units; and reidentification of the part.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. No comments were submitted in response
to the proposal or the FAA's determination of the cost to the public.
Conclusion
The FAA has determined that air safety and the public interest
require the adoption of the rule as proposed.
Cost Impact
We do not know how many aircraft equipped with Apollo GX series GPS
navigation units (software versions 3.0 through 3.4 inclusive) of the
affected design are on the U.S. Register. However, we do know that the
GPS navigation units might be installed on 1,176 aircraft worldwide. It
will take approximately 1 work hour per aircraft to accomplish the
required modification, at an average labor rate of $65 per work hour.
The parts manufacturer will provide the required parts at no cost to
the operator. Based on these figures, the cost impact of the AD on U.S.
operators is estimated to be $65 per aircraft.
The cost impact figure discussed above is based on assumptions that
no operator has yet accomplished any of the requirements of this AD
action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions. Manufacturer warranty remedies may be available
for labor costs associated with this AD. As a result, the costs
attributable to the AD may be less than stated above.
Regulatory Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption
