AD results from mandatory continuing
airworthiness information (MCAI)
issued by an airworthiness authority of
another country to identify and correct
an unsafe condition on an aviation
product. The proposed AD would
require actions that are intended to
address the unsafe condition described
in the MCAI.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. We are
prototyping this process and specifically
request your comments on its use. You
can find more information in FAA draft
Order 8040.2, ‘‘Airworthiness Directive
Process for Mandatory Continuing
Airworthiness Information,’’ which is
currently open for comments at
https://www.faa.gov/aircraft/draft_docs.
This streamlined process will allow us
to adopt MCAI safety requirements in a
more efficient manner and will reduce
safety risks to the public.
This process continues to follow all
existing AD issuance processes to meet
VerDate Aug<31>2005
18:57 Jun 16, 2006
Jkt 208001
legal, economic, Administrative
Procedure Act, and Federal Register
requirements. We also continue to
follow our technical decision-making
processes in all aspects to meet our
responsibilities to determine and correct
unsafe conditions on U.S.-certificated
products.
This proposed AD references the
MCAI and related service information
that we considered in forming the
engineering basis to correct the unsafe
condition. The proposed AD contains
text copied from the MCAI and for this
reason might not follow our plain
language principles.
The comment period for this
proposed AD is open for 30 days to
allow time for comments on both the
process and the AD content. In the
future, ADs using this process will have
a 15-day comment period, because the
airworthiness authority and
manufacturer have already published
the documents on which we based our
decision, making a longer comment
period unnecessary.
Comments Invited
We invite you to send any written
data, views, or arguments regarding this
proposed AD. Send your comments to
an address listed under the ADDRESSES
section. Include the docket number,
Docket No. FAA–2006–25060;
Directorate Identifier 2006–NM–119–AD
at the beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
the proposed AD. We are also inviting
comments, views, or arguments on the
new MCAI process. We will consider all
comments received by the closing date
and may amend the proposed AD in
light of those comments.
We will post all comments we
receive, without change, to
https://dms.dot.gov, including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
concerning this proposed AD.
Discussion
´ ´
The Direction Generale de l’Aviation
Civile (DGAC), which is the
airworthiness authority for France, has
issued French Airworthiness Directive
F–2005–155, dated August 31, 2005
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for the
specified products. The MCAI states
that some cases of slide damage and
deflation have been reported during
deployment tests at doors 2 and 3 of the
A321. Analysis has shown that the slide
may inflate too fast compared to the
associated door release. If there is a
PO 00000
Frm 00021
Fmt 4702
Sfmt 4702
35221
delay during the opening of the door,
the inflatable slide may exercise
pressure on this not yet opened door,
which could result in damage to the
inflatable slide. A slide not inflated
correctly may disrupt passenger
emergency evacuation. The MCAI
renders mandatory the removal of one of
the two inflating vacuums in order to
reduce the speed of the slide inflation.
You may obtain further information by
examining the MCAI in the docket.
Relevant Service Information
Airbus has issued Service Bulletin
A320–25–1416, dated May 20, 2005.
The actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
FAA’s Determination and Requirements
of the Proposed AD
This product is manufactured outside
the United States and is type certificated
for operation in the United States under
the provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
agreement. Pursuant to this bilateral
airworthiness agreement, the State of
Design’s airworthiness authority has
notified us of the unsafe condition
described in the MCAI and service
information referenced above. We have
examined the airworthiness authority’s
findings, evaluated all pertinent
information, and determined an unsafe
condition exists and is likely to exist or
develop on all products of this type
design. We are issuing this proposed AD
to correct the unsafe condition.
Differences Between the Proposed 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
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable in a U.S.
court of law. 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
described in a separate paragraph of the
proposed AD. These proposed
requirements, if ultimately adopted, will
take precedence over the actions copied
from the MCAI.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
E:\FR\FM\19JNP1.SGM
19JNP1
35222
Federal Register / Vol. 71, No. 117 / Monday, June 19, 2006 / Proposed Rules
affect about 37 products of U.S. registry.
We also estimate that it would take
about 5 work hours per product to do
the actions and that the average labor
rate is $80 per work hour. Required
parts would cost about $370 per
product. Where the service information
lists required parts costs that are
covered under warranty, we have
assumed that there will be no change 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
$28,490, or $770 per product.
wwhite on PROD1PC61 with PROPOSALS
Authority for This Rulemaking
Title 49 of the United States Code
specifies 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 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 have 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 that the 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.

airworthiness authority's findings, evaluated all pertinent
information, and determined an unsafe condition exists and is likely to
exist or develop on all products of this type design. We are issuing
this proposed AD to correct the unsafe condition.
Differences Between the Proposed 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 different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable in a U.S. court of
law. 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
described in a separate paragraph of the proposed AD. These proposed
requirements, if ultimately adopted, will take precedence over the
actions copied from the MCAI.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would
[[Page 35222]]
affect about 37 products of U.S. registry. We also estimate that it
would take about 5 work hours per product to do the actions and that
the average labor rate is $80 per work hour. Required parts would cost
about $370 per product. Where the service information lists required
parts costs that are covered under warranty, we have assumed that there
will be no change 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 $28,490, or $770 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies 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 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 have 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 that the 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.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at https://dms.dot.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5227)
is located at the street address stated 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, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the Federal Aviation Administration proposes to amend 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.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Airbus: Docket No. FAA-2006-25060; Directorate Identifier 2006-NM-
119-AD.
Comments Due Date
(a) We must receive comments on this airworthiness directive
(AD) by July 19, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus A321 aircraft, all certified
models and serial numbers that are equipped with escape slides, part
number (P/N) 62292-105, 62292-106, 62293-105, or 62293-106. Aircraft
on which no modification/replacement of escape slides at doors 2 and
3 has been performed since embodiment of Airbus Modification 34989
in production are not affected by the requirements of this AD.
Reason
(d) Some cases of slide damage and deflation have been reported
during deployment tests at doors 2 and 3 of the A321. Analysis has
shown that the slide may inflate too fast compared to the associated
door release. If there is a delay during the opening of the door,
the inflatable slide may exercise pressure on this not yet opened
door, which could result in damage to the inflatable slide. A slide
not inflated correctly may disrupt passenger emergency evacuation.
For such reason, this AD renders mandatory the removal of one of the
two inflating vacuums in order to reduce the speed of the slide
inflation.
Actions and Compliance
(e) Unless already done, do the following actions except as
stated in paragraph (f) below: Within 36 months after the effective
date of this AD: Modify the slides, P/N 62292-105, 62292-106, 62293-
105, or 62293-106, in accordance with the instructions given in
Airbus Service Bulletin A320-25-1416, dated May 20, 2005.
FAA AD Differences
(f) None.
