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 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 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.

Adoption of the Amendment
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:
2009-10-07 Airbus: Amendment 39-15902.
Docket No. FAA-2009-0433; Directorate
Identifier 2009-NM-003-AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective May 28, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A380-
841, -842 and -861 airplanes, certificated in
any category, all serial numbers.
Subject
(d) Air Transport Association (ATA) of
America Code 57: Wings.
Reason
(e) The mandatory continued airworthiness
information (MCAI) states:
"During the flight test campaign of the
A380-861 model (Engine Alliance powered),
some cracks were found on the Movable Flap
Track Fairing number 6 (MFTF#6).
"These cracks were located at the pivot
attachment support-ring and at the
"U-frame in the attachment area to aft-
kinematic. In addition, delamination has
been observed within the monolithic Carbon
Fibre Reinforced Plastic (CFRP) structure
around the pivot support-ring.
"This condition, if not corrected, could
lead to in-flight loss of the MFTF#6,
potentially resulting in injuries to persons on
the ground.
"To prevent the risk of a MFTF#6
detachment, this Airworthiness Directive
(AD) requires an inspection program in order
to detect cracks [and delamination] before
they become critical and in case of findingsto replace the MFTF#6 [with a new or
serviceable part]."Actions and Compliance
(f) Unless already done, do the following:
(1) At the applicable time specified in
paragraph (f)(1)(i) or (f)(1)(ii) of this AD for
the left- and right-hand MFTF#6, do a special
detailed (ultrasonic and high-frequency eddy
current) inspection of the filet radii of pivot
supports, monolithic carbon fibre reinforced
plastic structures, and radii of U-Frame, and
a general visual inspection of MFTF#6, for
cracking and delamination, in accordance
with the Accomplishment Instructions of
Airbus Service Bulletin A380-57-8014,
dated November 21, 2008.
(i) For Model A380-841 and -842
airplanes: Before the MFTF#6 has
accumulated 500 total flight cycles since its
first installation on an airplane, or within 30
flight hours after the effective date of this AD,
whichever occurs later.
(ii) For Model A380-861 airplanes: Before
the MFTF#6 has accumulated 100 total flight
cycles since its first installation on an
airplane, or within 30 flight hours after the
effective date of this AD, whichever occurs
later.
(2) If no cracking and no delamination are
detected during any inspection required by
paragraph (f)(1) of this AD, repeat the
inspections required by paragraph (f)(1) of
this AD thereafter at intervals not to exceed
the applicable time specified in paragraph
(f)(2(i) or (f)(2)(ii) of this AD.
(i) For Model A380-841 and -842
airplanes: 50 flight cycles.
(ii) For Model A380-861 airplanes: 10
flight cycles.
(3) If any cracking or delamination is found
during any inspection required by paragraph
(f)(1) or (f)(2) of this AD, before further flight,
replace the MFTF#6 with a new or
serviceable part, in accordance with the
Accomplishment Instructions of Airbus
Service Bulletin A380-57-8014, dated
November 21, 2008, and repeat the
inspections specified in paragraph (f)(1) of
this AD at the applicable time defined in
paragraph (f)(2) of this AD.
