Download as PDF Federal Register / Vol. 78, No. 128 / Wednesday, July 3, 2013 / Proposed Rules 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, 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); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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 an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

AGENCY: We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by reports of certain sliding windows that were difficult to operate after landing. This proposed AD would require a detailed inspection to identify part numbers of sliding windows and sliding window seals, and modification if necessary. This proposed AD also includes an optional replacement. We are proposing this AD to detect and correct incorrect seals, which could lead to the functional loss of the sliding window as an exit, possibly preventing the flightcrew from safely evacuating the airplane during an emergency. DATES: We must receive comments on this proposed AD by August 19, 2013.

Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent VerDate Mar<15>2010 16:18 Jul 02, 2013 Jkt 229001 for the Member States of the European Community, has issued EASA Airworthiness Directive 2013–0011, dated January 15, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Several occurrences have been reported on A320 family aeroplanes of PPG sliding windows that were difficult to operate after landing. The investigation results revealed that when a seal having Part Number (P/N) 22– 17–7640–1 or P/N 22–17–7640–2 is installed on a sliding window, closure of the window can create a vacuum between the 2 tubes of the pressure seal, leading to the window remaining stuck to the frame on the fuselage side, due to suction effect. This condition, if not detected and corrected, could lead to the functional loss of the sliding window as an exit, possibly preventing the flight crew from safely evacuating the aeroplane during an emergency. For the reasons described above, this [EASA] AD requires a one-time detailed inspection (DI) of the sliding windows and its seal to identify the affected sliding window seals and, depending on findings, accomplishment of the applicable corrective actions [corrective action includes a modification or replacement]. The subject area on certain Airbus Model A318, A319, and A321 series airplanes is almost identical to that on the affected Model A320 series airplanes. Therefore, those Model A318, A319, and A321 series airplanes may be subject to the unsafe condition revealed on the Model A320 series airplanes. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Airbus has issued Service Bulletin A320–56–1015, dated September 14, 2012; and Service Bulletin A320–56– 1016, including Appendices 01 and 02, dated September 14, 2012. PPG Aerospace has issued Service Bulletin 165312–56–001, dated February 29, 2012. 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 PO 00000 Frm 00014 Fmt 4702 Sfmt 4702 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 While paragraph (2) of EASA AD 2013–0011, dated January 15, 2013, requires modification of the sliding window seal before further flight, this AD requires modification of the sliding window seal within the compliance time specified in paragraph (g) of this AD. This difference has been coordinated with EASA. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 851 products of U.S. registry. We also estimate that it would take about 3 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $217,005, or $255 per product. In addition, we estimate that any necessary follow-on actions would take about 1 work-hour and require parts costing $0, for a cost of $85 per product. We have no way of determining the number of products that may need these actions. 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 E:\FR\FM\03JYP1.SGM 03JYP1 Federal Register / Vol. 78, No. 128 / Wednesday, July 3, 2013 / Proposed Rules 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); 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 proposed AD and placed it in the AD docket.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to certain The Boeing Company Model 777–200 and –300 series airplanes equipped with RollsRoyce engines. The existing AD currently requires repetitive inspections to detect cracks of the outer V-blades of the thrust reverser, and corrective action if necessary. The existing AD also provides for optional terminating action for the repetitive inspections. Since we issued that AD, we have received reports of cracked outer V-blade fittings at the hinge beam end of Rolls-Royce engine thrust reversers, on airplanes on tkelley on DSK3SPTVN1PROD with PROPOSALS SUMMARY: VerDate Mar<15>2010 16:18 Jul 02, 2013 Jkt 229001 which the optional terminating action was done. This proposed AD would add, for airplanes on which the optional terminating action is done, repetitive inspections for cracking in the outer Vblade fittings of the hinge beam and latch beam ends of each thrust reverser half, and replacement of an affected thrust reverser half if necessary. This proposed AD would also add airplanes to the applicability. We are proposing this AD to prevent separation of a thrust reverser from the airplane during normal reverse thrust or during a refused takeoff, which could result in unexpected thrust asymmetry and a possible runway excursion. DATES: We must receive comments on this proposed AD by August 19, 2013.

Discussion On December 14, 2006, we issued AD 2006–26–06, Amendment 39–14864 (71 FR 77586, December 27, 2006), for certain The Boeing Company Model 777–200 and –300 series airplanes, equipped with Rolls-Royce engines, as identified in Boeing Special Attention Service Bulletin 777–78–0064, Revision 1, dated November 30, 2006. That AD requires repetitive inspections to detect cracks of the outer V-blades of the thrust reverser, and corrective action if necessary. The existing AD also provides for optional terminating action for the repetitive inspections. That AD resulted from reports of cracked outer Vblades in the thrust reversers. We issued that AD to prevent separation of a thrust reverser from the airplane during normal reverse thrust or during a refused takeoff, which could result in impact damage to other airplane areas. If a thrust reverser separates from the airplane during a refused takeoff, the engine could produce forward thrust, resulting in unexpected thrust asymmetry and a possible runway excursion.

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A318, A319, A320, and A321 series airplanes. This proposed 
AD was prompted by reports of certain sliding windows that were 
difficult to operate after landing. This proposed AD would require a 
detailed inspection to identify part numbers of sliding windows and 
sliding window seals, and modification if necessary. This proposed AD 
also includes an optional replacement. We are proposing this AD to 
detect and correct incorrect seals, which could lead to the functional 
loss of the sliding window as an exit, possibly preventing the 
flightcrew from safely evacuating the airplane during an emergency.

DATES: We must receive comments on this proposed AD by August 19, 2013.

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 2013-0011, dated January 15, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Several occurrences have been reported on A320 family aeroplanes 
of PPG sliding windows that were difficult to operate after landing.
    The investigation results revealed that when a seal having Part 
Number (P/N) 22-17-7640-1 or P/N 22-17-7640-2 is installed on a 
sliding window, closure of the window can create a vacuum between 
the 2 tubes of the pressure seal, leading to the window remaining 
stuck to the frame on the fuselage side, due to suction effect.
    This condition, if not detected and corrected, could lead to the 
functional loss of the sliding window as an exit, possibly 
preventing the flight crew from safely evacuating the aeroplane 
during an emergency.
    For the reasons described above, this [EASA] AD requires a one-
time detailed inspection (DI) of the sliding windows and its seal to 
identify the affected sliding window seals and, depending on 
findings, accomplishment of the applicable corrective actions 
[corrective action includes a modification or replacement].

    The subject area on certain Airbus Model A318, A319, and A321 
series airplanes is almost identical to that on the affected Model A320 
series airplanes. Therefore, those Model A318, A319, and A321 series 
airplanes may be subject to the unsafe condition revealed on the Model 
A320 series airplanes. You may obtain further information by examining 
the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Service Bulletin A320-56-1015, dated September 
14, 2012; and Service Bulletin A320-56-1016, including Appendices 01 
and 02, dated September 14, 2012. PPG Aerospace has issued Service 
Bulletin 165312-56-001, dated February 29, 2012. 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

    While paragraph (2) of EASA AD 2013-0011, dated January 15, 2013, 
requires modification of the sliding window seal before further flight, 
this AD requires modification of the sliding window seal within the 
compliance time specified in paragraph (g) of this AD. This difference 
has been coordinated with EASA.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 851 products of U.S. registry. We also estimate that 
it would take about 3 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on U.S. operators to be $217,005, or $255 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour and require parts costing $0, for a cost of $85 
per product. We have no way of determining the number of products that 
may need these actions.

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

[[Page 40059]]

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);
    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 proposed AD and placed it in the AD docket.
