14 CFR Part 39
[Docket No. 96-NM-179-AD; Amendment 39-13028; AD 2003-03-04]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A300 B2 and B4; A300 B4-
600, B4-600R, and F4-600R (Collectively Called A300-600); A310; A319;
A320; A321; A330; and A340 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 B2 and B4; A300 B4-600, B4-600R,
and F4-600R (collectively called A300-600); A310; and certain Airbus
Model A319; A320; A321; A330; and A340 series airplanes, that requires
repetitive visual inspections of the striker and guide valve of the
passenger door actuators and certain emergency door actuators for
corrosion, and corrective action, if necessary. This AD also requires
modification of the striker mechanism of the emergency and passenger
door actuators, which terminates the repetitive inspections. This
amendment is prompted by issuance of mandatory continuing airworthiness
information by a foreign civil airworthiness authority. The actions
specified by this AD are intended to prevent corrosion of the emergency
actuator mechanism, which could cause failure of the emergency actuator
striker mechanism on the passenger or emergency doors, and lead to
difficulty in opening the passenger or emergency doors during an
emergency evacuation.
DATES: Effective March 7, 2003.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of March 7, 2003.
ADDRESSES: The service information referenced in this AD may be
obtained from Airbus Industrie, 1 Rond Point Maurice Bellonte, 31707
Blagnac Cedex, France. 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 Office of
the Federal Register, 800 North Capitol Street, NW., suite 700,
Washington, DC.
FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer, FAA,
Transport Airplane Directorate, International Branch, ANM-116, 1601
Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 227-
2125; fax (425) 227-1149.
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 B2 and B4;
A300 B4-600, B4-600R, and F4-600R (collectively called A300-600); A310;
and certain Airbus Model A319; A320; A321; A330; and A340 series
airplanes was published in the Federal Register on May 17, 2002 (67 FR
35059). That action proposed to require repetitive visual inspections
of the striker and guide valve of the passenger door actuators and
certain emergency door actuators for corrosion, and corrective action,
if necessary. That action also proposed to require modification of the
striker mechanism of the emergency and passenger door actuators, which
would terminate the repetitive inspections.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comment received.
Request To Allow Credit for Accomplishment of Earlier Service Bulletin
One commenter requests that the FAA allow credit for accomplishment
of Airbus Service Bulletin A320-52-1094, Revision 1, dated June 17,
1998, as terminating action for the repetitive inspections. We agree.
We find that the procedures specified in that service bulletin revision
are essentially identical to those specified in Revision 02 of the
service bulletin (which was referenced in the notice of proposed
rulemaking (NPRM) as an appropriate source of service information for
accomplishment of the terminating action). Therefore, we have revised
the final rule to include a new paragraph (g) to specify that
modification of the striker mechanism before the effective date of this
AD per Revision 1 of Airbus Service Bulletin A320-52-1094 is considered
acceptable for compliance with the requirements of paragraph (f) of
this AD (designated as paragraph (d) in the NPRM).
Explanation of Editorial Changes
Since the language in Notes 4 and 5 of the proposed AD is
regulatory in nature, those notes have been redesignated as paragraphs
(d) and (e) of this final rule, respectively (subsequent paragraphs and
notes also have been redesignated).
We have changed certain service bulletin citations throughout this
final rule to exclude the Service Bulletin Acceptance/Rejection Sheet.
The sheet is intended to be completed by operators and submitted to the
airplane manufacturer to provide inspection reports to Airbus; however,
this AD does not include such a requirement.
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 changes described
previously. The FAA has determined that these changes will neither
increase the economic burden on any operator nor increase the scope of
the AD.
Cost Impact
The FAA estimates that 127 Model A300 B2 and B4 and A300-600 series
airplanes of U.S. registry will be affected by this AD.
For these airplanes, it will take approximately 9 work hours per
airplane to accomplish the required inspections, at an average labor
rate of $60 per work hour. Based on these figures, the cost impact of
the inspections on U.S. operators is
[[Page 4890]]
estimated to be $68,580, or $540 per airplane, per inspection cycle.
It will take approximately 60 work hours per airplane to accomplish
the required modification, at an average labor rate of $60 per work
hour. Parts cost per airplane will be minimal. Based on these figures,
the cost impact of the modification on U.S. operators is estimated to
be $457,200, or $3,600 per airplane.
The FAA estimates that 47 Model A310 series airplanes of U.S.
registry will be affected by this AD, that it will take approximately 6
work hours per airplane to accomplish the required inspections, and
that the average labor rate is $60 per work hour. Based on these
figures, the cost impact of the inspections on U.S. operators is
estimated to be $16,920, or $360 per airplane, per inspection cycle.
For these airplanes, it will take approximately 20 work hours per
airplane to accomplish the required modification, at an average labor
rate of $60 per work hour. Parts cost per airplane will be minimal.
Based on these figures, the cost impact of the modification on U.S.
operators is estimated to be $56,400, or $1,200 per airplane.
The FAA estimates that 887 Model A319, A320, and A330 series
airplanes of U.S. registry will be affected by this AD, that it will
take approximately 4 work hours per airplane to accomplish the required
inspection, and that the average labor rate is $60 per work hour. Based
on these figures, the cost impact of the AD on U.S. operators of these
airplanes is estimated to be $212,880, or $240 per airplane, per
inspection cycle.
For these airplanes, it will take approximately 80 work hours per
airplane to accomplish the required modification, at an average labor
rate of $60 per work hour. Parts cost per airplane will be minimal.
Based on these figures, the cost impact of the modification on U.S.
operators is estimated to be $4,257,600, or $4,800 per airplane.
The cost impact figures discussed above are 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.
There are currently no affected Model A321 or A340 series airplanes
on the U.S. Register. All of these airplanes included in the
applicability of this rule currently are operated by non-U.S. operators
under foreign registry; therefore, they are not directly affected by
this AD action. However, the FAA considers it necessary to include
these airplanes in the applicability of this rule in order to ensure
that the unsafe condition is addressed in the event that any of the
subject airplanes are imported and placed on the U.S. Register in the
future.
Should an affected Model A321 series airplane be imported and
placed on the U.S. Register in the future, it will take approximately 8
work hours per airplane to accomplish the required inspections. Based
on an average labor rate of $60 per work hour, the cost impact of the
inspections would be $480 per airplane, per inspection cycle.
It will take approximately 20 work hours per airplane to accomplish
the required modification on a Model A321 series airplane. Parts cost
per airplane will be minimal. Based on an average labor rate of $60 per
work hour, the cost impact of the modification will be $1,200 per
airplane.
Should an affected Model A340 series airplane be imported and
placed on the U.S. Register in the future, it will take approximately
32 work hours per airplane to accomplish the required inspections.
Based on an average labor rate of $60 per work hour, the cost impact of
the inspections would be $1,920 per airplane, per inspection cycle.
It will take approximately 80 work hours per airplane to accomplish
the required modification on a Model A340 series airplane. Parts cost
per airplane will be minimal. Based on an average labor rate of $60 per
work hour, the cost impact of the modification would be $4,800 per
airplane.
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
