AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:
Two incidents have occurred due to the lack of visibility on the
Primary Flight Display (PFD) of the Traffic Alert and Collision
Avoidance System (TCAS) indications.
* * * * *
We are issuing this AD to prevent possible mid-air collisions due to
lack of visibility of TCAS indications on the PFD. The proposed AD
would require actions that are intended to address the unsafe condition
described in the MCAI.
DATES: We must receive comments on this proposed AD by December 17,
2008.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2008-0032, dated February 21, 2008 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Two incidents have occurred due to the lack of visibility on the
Primary Flight Display (PFD) of the Traffic Alert and Collision
Avoidance System (TCAS) indications.
EIS2 [electronic instrument system 2] standard S7 introduces
modifications to the vertical speed indication to improve the
legibility in case of TCAS Resolution Advisory.
The modifications consist in changing the colour of the needle
and increasing the width of the TCAS green band.
This AD supersedes [EASA] AD 2006-0108 [dated May 3, 2006].
Also, as all aircraft in this AD applicability have been retrofitted
to at least S4.2 standard, the operational limitations contained in
the Compliance paragraph 2. of AD 2006-0108 have already been
addressed.
This AD therefore mandates the installation of the improved EIS2
standard S7.
We are issuing this AD to prevent possible mid-air collisions due to
lack of visibility of TCAS indications on the PFD. You may obtain
further information by examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued Service Bulletin A320-31-1276, Revision 01, dated
March 5, 2008. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use
[[Page 67814]]
different words from those in the MCAI to ensure the AD is clear for
U.S. operators and is enforceable. In making these changes, we do not
intend to differ substantively from the information provided in the
MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 113 products of U.S. registry. We also estimate that
it would take about 4 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $0 per product. Where the
service information lists required parts costs that are covered under
warranty, we have assumed that there will be no charge for these costs.
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 the proposed AD on U.S. operators to
be $36,160, or $320 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 proposed
regulation:
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 proposed AD and placed it in the AD docket.

072-AD.
Comments Due Date
(a) We must receive comments by December 17, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A318-111, A318-112, A319-
111, A319-112, A319-113, A319-114, A319-115, A319-131, A319-132,
A319-133, A320-111, A320-211, A320-212, A320-214, A320-231, A320-
232, A320-233, A321-111, A321-112, A321-131, A321-211, A321-212,
A321-213, A321-231, and A321-232, certificated in any category;
equipped with EIS2 (electronic instrument system 2) standard S4.2
(DMC disk part number F1419418) installed by Airbus Modification
34571, or Airbus Service Bulletin A320-31A1220, or Airbus Service
Bulletin A320-31-1234; except those airplanes on which Airbus
Modification 36725 has been embodied in production.
Subject
(d) Air Transport Association (ATA) of America Code 31:
Instruments.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Two incidents have occurred due to the lack of visibility on the
Primary Flight Display (PFD) of the Traffic Alert and Collision
Avoidance System (TCAS) indications.
EIS2 standard S7 introduces modifications to the vertical speed
indication to improve the legibility in case of TCAS Resolution
Advisory.
The modifications consist in changing the colour of the needle
and increasing the width of the TCAS green band.
This AD supersedes AD 2006-0108 [dated May 3, 2006]. Also, as
all aircraft in this AD applicability have been retrofitted to at
least S4.2 standard, the operational limitations contained in the
Compliance paragraph 2. of AD 2006-0108 have already been addressed.
This AD therefore mandates the installation of the improved EIS2
standard S7.
We are issuing this AD to prevent possible mid-air collisions due to
lack of visibility of TCAS indications on the PFD.
Actions and Compliance
(f) Unless already done, do the following actions:
(1) Within 12 months after the effective date of this AD,
install EIS2 standard S7 (DMC disk part number F1461768), in
accordance with the Accomplishment Instructions of Airbus Service
Bulletin A320-31-1276, Revision 01, dated March 5, 2008.
(2) Installations done before the effective date of this AD in
accordance with Airbus Service Bulletin A320-31-1263, Revision 01,
dated July 20, 2007; Airbus Service Bulletin A320-31-1263, Revision
02, dated August 10, 2007; Airbus Service Bulletin A320-31-1263,
Revision 03, dated November 23, 2007; or Airbus Service Bulletin
A320-31-1276, dated April 18, 2007; are acceptable for compliance
with the requirements of paragraph (f)(1) of this AD.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows:
(1) This AD does not include the operational limitations
specified in paragraph 1 of the MCAI. The MCAI carried these
limitations forward from European Aviation Safety Agency (EASA)
Airworthiness Directive 2006-0108, dated May 3, 2006. The FAA-
approved Master Minimum Equipment List (MMEL) already contains these
and more restrictive operational limitations, and we previously
determined that no action was required on our part regarding this
provision of EASA AD 2006-0108.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, ANM-
116, International Branch, Transport Airplane Directorate, FAA, has
the authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19.

Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-
2141; fax (425) 227-1149. Before using any approved AMOC on any
airplane to which the AMOC applies, notify your appropriate
principal inspector (PI) in the FAA Flight Standards District Office
(FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
