ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for all
Airbus Model A318, A319, and A320
series airplanes. This proposed AD was
prompted by reports of unsuccessful
slide deployments during scheduled
deployment tests, and failed functional
tests of the release travel of the slide
release mechanism. This proposed AD
would require inspecting the off-wing
slide release cables on the left- and
right-hand sides to determine whether a
certain part number is installed, and
replacement if necessary. We are
proposing this AD to prevent nonavailability of left- or right-hand offwing exit slides that could impair
emergency evacuation of the passengers
and flightcrew, and could result in
personal injuries.
DATES: We must receive comments on
this proposed AD by April 30, 2012.
ADDRESSES: You may send comments by
any of the following methods:

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 2011–0015,
dated January 31, 2011 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
Several operators reported unsuccessful
slide deployments during scheduled
deployment tests and/or failed functional
tests of the release travel of the slide release
mechanism.
Investigations revealed deformation of the
PTFE (Teflon) ball guide strip of the release
cable, Part Number (P/N) L32A319–160–001.
In such a situation the travel of the cable
could be insufficient to open the valve when
opening the exit, thereby reducing the gas
flow from the reservoir to the off-wing slide
in automatic or manual mode. As a result, the
aspirator will not ingest sufficient ambient
air for slide inflation.
This condition, if not corrected, could lead
to the non-availability of LH [left-hand] and/
or RH [right-hand] off-wing exit slides for
evacuation that would impair emergency
evacuation of the aeroplane occupants,
possibly resulting in personal injuries.
For the reasons described above, this
[EASA] AD requires the identification
[inspection] and replacement of both Left
hand (LH) and Right Hand (RH) off-wing
slide release cables P/N L32A319–160–001
with P/N L32A320–180, which have precise
stainless steel ball bearing stripes instead of
stamped PTFE stripes.
You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Airbus has issued the service
bulletins listed below. The actions
described in this service information are
intended to correct the unsafe condition
identified in the MCAI.
• Airbus Service Bulletin A320–28–
1118, Revision 03, including Appendix
1, dated May 12, 2009.
• Airbus Service Bulletin A320–28–

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
This AD differs from the MCAI and/
or service information as follows:
Although the MCAI states that no
person may install an off-wing slide
release cable having P/N L32A319–160–
001 on any airplane after the
modifications specified in paragraphs
(g) or (h) of this AD have been done, or
on airplanes that do not have P/N
L32A319–160–001 installed as of the
effective date of the MCAI, this AD
requires that, as of the effective date of
this AD, no person may install an offwing slide release cable having P/N
L32A319–160–001 on any airplane.

Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 694 products of U.S.
registry. We also estimate that it would
take about 39 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Required
parts would cost about $5,750 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 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 the
proposed AD on U.S. operators to be
$6,291,110, or $9,065 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.
VerDate Mar<15>2010
16:45 Mar 15, 2012
Jkt 226001
15637
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.
(a) Comments Due Date
Regulatory Findings
Air Transport Association (ATA) of
America Code 28: Fuel tanks; 53: Fuselage.
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 that 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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

ACTION: Supplemental notice of
proposed rulemaking (NPRM);

AGENCY:
We are revising an earlier
proposed airworthiness directive (AD)
for certain The Boeing Company Model
737–600, –700, –700C, –800, –900 and
–900ER series airplanes. That NPRM
proposed to require modifying the fluid
drain path in the wing leading edge
area, forward of the wing front spar, and
doing all applicable related investigative
and corrective actions. That NPRM was
prompted by a report of leaking fuel
from the wing leading edge area at the
inboard end of the number 5 leading
edge slat. This action revises that NPRM
by including installing new seal disks
on the latches in the fuel shutoff valve
access door as part of the modification
and by specifying that certain
inspections are detailed inspections.
This action also revises the applicability
to include additional airplanes. We are
proposing this AD to prevent flammable
fluids from accumulating in the wing

inspecting the off-wing slide release cables on the left- and right-
hand sides to determine whether a certain part number is installed, and
replacement if necessary. We are proposing this AD to prevent non-

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 2011-0015, dated January 31, 2011 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Several operators reported unsuccessful slide deployments during
scheduled deployment tests and/or failed functional tests of the
release travel of the slide release mechanism.
Investigations revealed deformation of the PTFE (Teflon) ball
guide strip of the release cable, Part Number (P/N) L32A319-160-001.
In such a situation the travel of the cable could be insufficient to
open the valve when opening the exit, thereby reducing the gas flow
from the reservoir to the off-wing slide in automatic or manual
mode. As a result, the aspirator will not ingest sufficient ambient
air for slide inflation.
This condition, if not corrected, could lead to the non-
availability of LH [left-hand] and/or RH [right-hand] off-wing exit
slides for evacuation that would impair emergency evacuation of the
aeroplane occupants, possibly resulting in personal injuries.
For the reasons described above, this [EASA] AD requires the
identification [inspection] and replacement of both Left hand (LH)
and Right Hand (RH) off-wing slide release cables P/N L32A319-160-
001 with P/N L32A320-180, which have precise stainless steel ball
bearing stripes instead of stamped PTFE stripes.
You may obtain further information by examining the MCAI in the AD
docket.

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
This AD differs from the MCAI and/or service information as
follows: Although the MCAI states that no person may install an off-
wing slide release cable having P/N L32A319-160-001 on any airplane
after the modifications specified in paragraphs (g) or (h) of this AD
have been done, or on airplanes that do not have P/N L32A319-160-001
installed as of the effective date of the MCAI, this AD requires that,
as of the effective date of this AD, no person may install an off-wing
slide release cable having P/N L32A319-160-001 on any airplane.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 694 products of U.S. registry. We also estimate that
it would take about 39 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Required parts would cost about $5,750 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
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 the proposed AD on U.S. operators to
be $6,291,110, or $9,065 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 that 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
