14 CFR Part 39
[Docket No. 2001-NM-303-AD; Amendment 39-13454; AD 2004-03-10]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, and
F4-600R (Collectively Called A300-600) Series Airplanes; and Model A310
Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all Airbus Model A300 B4-600, B4-600R, and F4-600R
(collectively called A300-600) series airplanes; and Model A310 series
airplanes. This AD requires revising the Airplane Flight Manual (AFM)
to provide the flight crew with procedures to maintain controllability
of the airplane in the event of an in-flight deployment of the thrust
reverser. This action is necessary to ensure that the flight crew is
advised of the potential hazard associated with an in-flight deployment
of the thrust reverser, and the procedures necessary to address it.
This action is intended to address the identified unsafe condition.
DATES: Effective March 15, 2004.
ADDRESSES: Information pertaining to this amendment may be examined at
the Federal Aviation Administration (FAA), Transport Airplane
Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, Washington.
FOR FURTHER INFORMATION CONTACT: Tim Backman, Aerospace Engineer,
International Branch, ANM-116, FAA, Transport Airplane Directorate,

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 all Airbus Model A300 B4-600, B4-
600R, and F4-600R (collectively called A300-600) series airplanes; and
Model A310 series airplanes; was published in the Federal Register on
August 9, 2002 (67 FR 51787). That action proposed to require revising
the Airplane Flight Manual (AFM) to provide the flight crew with
procedures to maintain controllability of the airplane in the event of
an in-flight deployment of the thrust reverser.

Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the single comment received.
Request To Clarify What AFM Section Must Be Revised
One commenter requests that the FAA clarify what section of the AFM
must be revised. The commenter notes that the ``Explanation of
Requirements of Proposed Rule'' section of the Notice of Proposed
Rulemaking (NPRM) states, ``the proposed AD would require revising the
Limitations and Procedures section of the AFM.'' The commenter notes
that the body of the AD does not specify to revise the Limitations
section of the AFM.
We agree that the reference in the ``Explanation of Requirements of
Proposed Rule'' section of the NPRM is incorrect. That section is not
restated in this final rule; thus, no change is necessary in this
regard.
Explanation of Change to Final Rule
We recognize that the provisions of the AFM revision required by
this AD may already have been incorporated into the AFM of affected
airplanes through a general revision of the AFM. Thus, we have added a
new Note 1 to this final rule (and reidentified subsequent notes
accordingly) to state that, when a ``ENG REV UNLK'' procedure identical
to that in paragraph (a) of this AD has been included in the general
revisions of the AFM, inserting the general revisions into the AFM is
acceptable for compliance with this AD.
Conclusion
After careful review of the available data, including the comment
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule with the change described
previously. The FAA has determined that this change will neither
increase the economic burden on any operator nor increase the scope of
the AD.
Changes to 14 CFR Part 39/Effect on the AD
On July 10, 2002, the FAA issued a new version of 14 CFR part 39
(67 FR 47997, July 22, 2002), which governs the FAA's airworthiness
directives system. The regulation now includes material that relates to
altered products, special flight permits, and alternative methods of
compliance. However, for clarity and consistency in this final rule, we
have retained the language of the NPRM regarding that material.
Explanation of Change to Cost Impact
After the proposed AD was issued, we reviewed the figures we use to
calculate the labor rate to do the required actions. To account for
various inflationary costs in the airline industry, we find it
appropriate to increase the labor rate used in these calculations from
$60 per work hour to $65 per work hour. The economic impact
information, below, has been revised to reflect this increase in the
specified hourly labor rate.
Cost Impact
The FAA estimates that 128 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 1 work hour per
airplane to accomplish the proposed AFM revision, and that the average
labor rate is $65 per work hour. Based on these figures, the cost
impact of this AD on U.S. operators is estimated to be $8,320, or $65
per airplane.
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.
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

To ensure that the flight crew is advised of the potential
hazard associated with an in-flight deployment of the thrust
reverser, and the procedures necessary to address it, accomplish the
following:
Revisions to the Airplane Flight Manual
(a) Within 60 days after the effective date of this AD, revise
the Procedures Following Failures section of the Airplane Flight
Manual (AFM) to include the ``ENG REV UNLK'' procedure contained in
this paragraph of this AD. This may be accomplished by inserting a
copy of this AD into the AFM.
``For airplanes fitted with ECAM SGU standard W23 or above:
ENG REV UNLK (MOD 10264 or MOD 10908 or 11318)
--THROTTLE............................. IDLE
--MAX SPEED............................ 300 KT
IF BUFFET OR BANK:
--FUEL LEVER........................... OFF
--MAX SPEED............................ 240 KT
--Approach Speed: 1.3 Vs of selected
landing configuration plus 10 kt. For
airplanes fitted with ECAM SGU
standard earlier than W23:
ENG REV UNLK
--THROTTLE............................. IDLE (memory item)
--MAX SPEED............................ 300 KT (memory item)
IF BUFFET OR BANK:
--FUEL LEVER........................... OFF

Note 1: When an ``ENG REV UNLK'' procedure identical to that in
paragraph (a)
[[Page 5928]]
of this AD has been included in the general revisions of the AFM,
the general revisions may be inserted into the AFM, and the copy of
this AD may be removed from the AFM.
Alternative Methods of Compliance
(b) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, International Branch, ANM-116,
Transport Airplane Directorate, FAA. Operators shall submit their
requests through an appropriate FAA Principal Maintenance Inspector,
who may add comments and then send it to the Manager, International
Branch, ANM-116.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Manager, International Branch, ANM-116.
Special Flight Permits
(c) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
Note 3: The subject of this AD is addressed in French
airworthiness directive 2001-186(B), dated May 16, 2001.
