Federal Register/Vol. 74, No. 14/Friday, January 23, 2009/Rules and Regulations
on U.S. operators to be $1,320,000, or
$2,400 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 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.
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 inthe AD docket shortly after receipt.

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
m 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:
2009-01-04 Airbus: Amendment 39-15783.
Docket No. FAA-2008-0558; Directorate
Identifier 2007-NM-365-AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective February 27, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A318,
A319, A320, and A321 airplanes, certificated
in any category; all certified models; all serial
numbers; on which classical standby
instruments have been installed per Airbus
Modification 20011 or 21999 in production,
or per Airbus Service Bulletin A320-34-1280
in service; excluding airplanes identified in
paragraphs (c)(1) or (c)(2) of this AD.
(1) Airplanes on which ISIS equipment
was installed per Airbus Modification 27620
in production or per Airbus Service Bulletin
A320-34-1261 or Airbus Service Bulletin
A320-34-1372 in service.
(2) Airplanes on which Airbus
Modification 37329 or 37330 was installed in
production or per Airbus Service Bulletin
A320-33-1057 in service.
Subject
(d) Air Transport Association (ATA) of
America Code 33: Lights.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
"Some operators have reported
occurrences of loss of the AC BUS 1 with
subsequent loss of the AC ESS BUS and DC
ESS BUS, resulting in the loss of 5 upper
Display Units and the loss of integral
lighting. In this situation, flight crews[s] have
reported concerns in reading the standby
instruments when the DOME lights were
selected to OFF.
"This situation, if not corrected, could
increase the workload of the flight crew
"This Airworthiness Directive (AD)
mandates the modification of the electricalsupply logic by adding a back-up supply on
the battery hot bus for the under glare shield
flood lighting."
The unsafe condition is reduced ability of the
flightcrew to maintain the safe flight and
landing of the airplane in adverse operating
conditions.
Actions and Compliance
(f) Unless already done, within 42 months
after the effective date of this AD: Modify the
electrical supply logic of the under glare
shield flood lighting in accordance with the
instructions given in Airbus Mandatory
Service Bulletin A320-33-1057, Revision 01,
dated January 31, 2008. Modifications done
before the effective date of this AD in
accordance with Airbus Service Bulletin
A320-33-1057, dated May 11, 2007, are
acceptable for compliance with the
modification in this paragraph.
