Federal Register/Vol. 75, No. 98/Friday, May 21, 2010/Rules and Regulations
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow our FAA
policies. Any such differences are
highlighted in a NOTE within the AD.
Explanation of Change to Costs of
Compliance
Since issuance of the NPRM, we have
increased the labor rate used in the
Costs of Compliance from $80 per work-
hour to $85 per work-hour. The Costs of
Compliance information, below, reflects
this increase in the specified hourly
labor rate.
Costs of Compliance
We estimate that this AD will affect
32 products of U.S. registry. We also
estimate that it will take about 244
work-hours per product to comply with
the basic requirements of this AD. The
average labor rate is $85 per work-hour.
Required parts costs are negligible.
Where the service information lists
required parts costs that are covered
under warranty, we have assumed that
there will be no charge for these parts.
As we do not control warranty coverage
for affected parties, some parties may
incur costs higher than estimated here.
Based on these figures, we estimate the
cost of this AD to the U.S. operators to
be $663,680, or $20,740 per product.
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 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 betweenthe 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 this AD:
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 AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on
the Internet at http://
www.regulations.gov; or in person at the
Docket Operations office between 9 a.m.
and 5 p.m., Monday through Friday,
except Federal holidays. The AD docket
contains the NPRM, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone
(800) 647-5527) is in the ADDRESSES
section. Comments will be available in
the AD docket shortly after receipt.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
Adoption of the Amendment
a Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
PART 39-AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
39.13 [Amended]
2. The FAA amends 39.13 by adding
the following new AD:
2010-10-25 Airbus: Amendment 39-16304.
Docket No. FAA-2009-0914; Directorate
Identifier 2009-NM-122-AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective June 25, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A330-
201, -202, -203, -223, -243, -301, -302,-303, -321, -322, -323, -341, -342, and -343
airplanes; and Airbus Model A340-311,
-312, and -313 airplanes; certificated in any
category; all manufacturer serial numbers on
which Airbus Modification 48825 has been
embodied in production, except those on
which Airbus Modification 57409 has been
embodied in production.
Subject
(d) Air Transport Association (ATA) of
America Code 92.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
In the door 2 area, the hat-racks are
supplied with a basic wire harness which
includes "Oxygen Masks" activation.
In case of a monument installation, the
respective non-used hat-rack connections
between monument and outer skin are put on
stow. It was noticed in production, that the
distance between the stowed wire harness
and the monument could be too small. This
condition, if not corrected, could lead to the
short circuit of wires dedicated to oxygen,
which, in case of emergency, could result in
a large number of passenger oxygen masks
not being supplied with oxygen, possibly
causing personal injuries.
For the reasons described above, this AD
requires the modification of the hat rack
connectors on stow, and the rerouting of the
associated wire harness in case of monument
installed in door 2 area.
Actions and Compliance
(f) Unless already done, do the following
actions.
(1) For airplanes on which a monument is
installed in the door 2 area, as specified in
