DEPARTMENT OF TRANSPORTATION RIN 2120–AA64 Airworthiness Directives; Airbus Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule; request for comments. AGENCY: We are adopting a new airworthiness directive (AD) for all Airbus Model A340–600 series airplanes. This AD requires a detailed inspection for abnormalities of the ball lock retainer on the off-wing ramp slides; for closure of the soft cover; for full engagement of the slide release pin; for broken, missing, and improper placement of the safety tie thread on the slide release pin; and for proper functioning of the vent valve; and replacement of the off-wing ramp slides if necessary. This AD was prompted by reports of in-flight loss of the blow-out panel and the slide unit from a righthand off-wing ramp-slide. We are issuing this AD to detect and correct abnormalities of the ball lock retainer, if the soft cover is open, if the slide pin release is not engaged or the safety tie thread is missing, broken, or improperly placed and the vent valve is not functioning properly, which could result in in-flight loss of the off-wing ramp slide. DATES: This AD becomes effective April 16, 2012. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of April 16, 2012.

SUPPLEMENTARY INFORMATION: 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 2011–0017, dated February 3, 2011 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: An A340–600 operator has reported an inflight loss of the blow-out panel and the slide unit from a Right Hand (RH) off-wing rampslide. Investigation has revealed that the two main contributor factors of a potential inflight loss of the slide are the packboard soft covers not fully closed and the vent valve not activated. In flight, the air contained in the inflatable assembly could increase in volume due to air pressure changes. Consequently, pack growth could occur and apply loads on the packboard soft covers and the blow-out panel attachment hardware. To prevent a pack growth, a vent valve is installed and when activated can balance pressure inside the inflatable assembly with the ambient air pressure. Analysis indicates that non activation of the vent valve, followed by soft cover opening, could cause the packboard blow-out panel to separate from the slide enclosure, resulting in in-flight loss of the off-wing ramp slide, which would constitute an unsafe condition. For the reasons described above, this AD requires a one-time inspection [check] of the soft cover condition and check of the vent valve function on each off-wing ramp slide, and accomplishment of the applicable corrective actions [replacement of the offwing ramp slide]. E:\FR\FM\30MRR1.SGM 30MRR1 19066 Federal Register / Vol. 77, No. 62 / Friday, March 30, 2012 / Rules and Regulations The one-time inspection consists of a detailed inspection for abnormalities of the ball lock retainer on the off-wing ramp slides; for closure of the soft cover; for full engagement of the slide release pin; for broken, missing, and improper placement of the safety tie thread on the slide release pin; and for proper functioning of the vent valve.

We will also post a report summarizing each substantive verbal contact we receive about this AD. Adoption of the Amendment Authority for This Rulemaking ■ Relevant Service Information 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. Airbus has issued All Operators Telex A340–25A5191, dated January 18, 2011. 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 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. There are no products of this type currently registered in the United States. However, this rule is necessary to ensure that the described unsafe condition is addressed if any of these products are placed on the U.S. Register in the future. FAA’s Determination of the Effective Date Since there are currently no domestic operators of this product, notice and opportunity for public comment before issuing this AD are unnecessary. sroberts on DSK5SPTVN1PROD with RULES Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment.

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A340-600 series airplanes. This AD requires a detailed 
inspection for abnormalities of the ball lock retainer on the off-wing 
ramp slides; for closure of the soft cover; for full engagement of the 
slide release pin; for broken, missing, and improper placement of the 
safety tie thread on the slide release pin; and for proper functioning 
of the vent valve; and replacement of the off-wing ramp slides if 
necessary. This AD was prompted by reports of in-flight loss of the 
blow-out panel and the slide unit from a right-hand off-wing ramp-
slide. We are issuing this AD to detect and correct abnormalities of 
the ball lock retainer, if the soft cover is open, if the slide pin 
release is not engaged or the safety tie thread is missing, broken, or 
improperly placed and the vent valve is not functioning properly, which 
could result in in-flight loss of the off-wing ramp slide.

DATES: This AD becomes effective April 16, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 16,

SUPPLEMENTARY INFORMATION: 

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 2011-0017, dated February 3, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The MCAI states:

    An A340-600 operator has reported an in-flight loss of the blow-
out panel and the slide unit from a Right Hand (RH) off-wing ramp-
slide.
    Investigation has revealed that the two main contributor factors 
of a potential in-flight loss of the slide are the packboard soft 
covers not fully closed and the vent valve not activated.
    In flight, the air contained in the inflatable assembly could 
increase in volume due to air pressure changes. Consequently, pack 
growth could occur and apply loads on the packboard soft covers and 
the blow-out panel attachment hardware. To prevent a pack growth, a 
vent valve is installed and when activated can balance pressure 
inside the inflatable assembly with the ambient air pressure.
    Analysis indicates that non activation of the vent valve, 
followed by soft cover opening, could cause the packboard blow-out 
panel to separate from the slide enclosure, resulting in in-flight 
loss of the off-wing ramp slide, which would constitute an unsafe 
condition.
    For the reasons described above, this AD requires a one-time 
inspection [check] of the soft cover condition and check of the vent 
valve function on each off-wing ramp slide, and accomplishment of 
the applicable corrective actions [replacement of the off-wing ramp 
slide].


[[Page 19066]]


The one-time inspection consists of a detailed inspection for 
abnormalities of the ball lock retainer on the off-wing ramp slides; 
for closure of the soft cover; for full engagement of the slide release 
pin; for broken, missing, and improper placement of the safety tie 
thread on the slide release pin; and for proper functioning of the vent 
valve. You may obtain further information by examining the MCAI in the 
AD docket.

Relevant Service Information

    Airbus has issued All Operators Telex A340-25A5191, dated January 
18, 2011. 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 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, 
notice and opportunity for public comment before issuing this AD are 
unnecessary.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2012-0295; Directorate 
Identifier 2011-NM-057-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 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.

2012-06-12 Airbus: Amendment 39-16993. Docket No. FAA-2012-0295; 
Directorate Identifier 2011-NM-057-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective April 16, 
2012.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Airbus Model A340-642 airplanes, certificated 
in any category, all manufacturer serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 25: Equipment/
Furnishings.

(e) Reason

    This AD was prompted by reports of in-flight loss of the blow-
out panel and the slide unit from a right-hand off-wing ramp-slide. 
We are issuing this AD to detect and correct abnormalities of the 
ball lock retainer, if the soft cover is open, if the slide pin 
release is not engaged or the safety tie thread is missing or 
broken, and the vent valve is not functioning properly, which could 
result in in-flight loss of the off-wing ramp slide.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Actions

    Within 90 days after the effective date of this AD, do a 
detailed inspection for abnormalities of the ball lock retainer on 
the off-wing ramp slides; for closure of the soft cover; for full 
engagement of the slide release pin; for broken, missing, and 
improper placement of the safety tie thread on the slide release 
pin; and for proper function of the vent valve; in accordance with 
Airbus All Operators Telex (AOT) A340-25A5191, dated January 18, 
2011. If the ball lock retainer has abnormalities, the soft cover is 
open, or the slide pin release is not engaged, or the safety tie 
thread is broken, missing, or improperly placed, or the vent valve 
is not functioning properly, before further flight, replace the off-
wing ramp slide, in accordance with Airbus AOT A340-25A5191, dated 
January 18, 2011.
