Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued AD No.: 2015– 0071, dated: April 30, 2015 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: In 1997, Piaggio Aero Industries S.p.A (PAI) developed a modification of the forward pressurized bulkhead, published through PAI Service Bulletin (SB) 80–0081, aiming to restore the safe fatigue life of the bulkhead structure. Consequently, ENAC Italy (formerly RAI) issued Prescrizione di Aeronavigabilita (PA) 97–148 to require compliance with this SB. After RAI PA 97–148 was issued, PAI issued SB 80–0081 Revision 2 to provide improved instructions for specific serial numbers. Prompted by this development, EASA issued AD 2010–0146 superseding PA 97–148 and requiring accomplishment of instruction of PAI issued SB 80–0081 Revision 2. After that AD was issued, PAI issued SB 80–0081 Revision 3 to make the instructions for inspection (and, depending on findings, rework/reinforcement) applicable to all aeroplanes. For the reasons described above, this AD retains the requirements of EASA AD 2010– 0146, which is superseded, requires inspection and, depending on findings, reinforcement of the pressurized bulkhead structure on extended population of aeroplanes. This AD also specifies that certain aeroplanes modified in accordance with SB 80–0081 up to Revision 2 need to be inspected and, depending on findings, reinforced as required by this AD. You may examine the MCAI on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2015–2466. Related Service Information Under 1 CFR Part 51 Piaggio Aero Industries S.p.A has issued Piaggio Aero Industries S.p.A. Service Bulletin 80–0081, Revision No. 3, dated: January 20, 2015. The service information describes procedures for inspection and, depending on findings, rework/reinforcement of the bulkhead. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means E:\FR\FM\06JYP1.SGM 06JYP1 Federal Register / Vol. 80, No. 128 / Monday, July 6, 2015 / Proposed Rules identified in the ADDRESSES section of this NPRM. FAA’s Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Lhorne on DSK7TPTVN1PROD with PROPOSALS Costs of Compliance We estimate that this proposed AD will affect 28 products of U.S. registry. We also estimate that it would take about 1 work-hour 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 $2,380, or $85 per product. In addition, we estimate that any necessary follow-on actions would take about 88 work-hours and require parts costing $30,000, for a cost of $37,480 per product. We have no way of determining the number of products that may need these actions. According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. 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 VerDate Sep<11>2014 14:36 Jul 02, 2015 Jkt 235001 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), (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.

Discussion While replacing a cracked underwing longeron fitting, a crack indication was found in the STA 786 ring chord at the tension bolt hole common to the wing front spar lower chord and the internal bathtub fittings. There were two similar reports of these findings from two separate operators. The airplanes in these reports had 14,367 and 18,354 flight cycles and 90,389 and 96,826 flight hours, respectively. The current inspections in the Model 767 Maintenance Planning Document are not sufficient to detect any possible fuselage skin crack in the area adjacent to the ring chord at STA 786 before the crack extends to a critical length. The fuselage skin in this area is hidden between the splice fittings on the external side of the fuselage and the bathtub fittings on the internal side. This condition, if not corrected, could result in loss of a primary load path between the fuselage and the wing box, and consequent reduced structural integrity of the airplane.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued AD 
No.: 2015-0071, dated: April 30, 2015 (referred to after this as ``the 
MCAI''), to correct an unsafe condition for the specified products. The 
MCAI states:

    In 1997, Piaggio Aero Industries S.p.A (PAI) developed a 
modification of the forward pressurized bulkhead, published through 
PAI Service Bulletin (SB) 80-0081, aiming to restore the safe 
fatigue life of the bulkhead structure.
    Consequently, ENAC Italy (formerly RAI) issued Prescrizione di 
Aeronavigabilita (PA) 97-148 to require compliance with this SB.
    After RAI PA 97-148 was issued, PAI issued SB 80-0081 Revision 2 
to provide improved instructions for specific serial numbers. 
Prompted by this development, EASA issued AD 2010-0146 superseding 
PA 97-148 and requiring accomplishment of instruction of PAI issued 
SB 80-0081 Revision 2.
    After that AD was issued, PAI issued SB 80-0081 Revision 3 to 
make the instructions for inspection (and, depending on findings, 
rework/reinforcement) applicable to all aeroplanes.
    For the reasons described above, this AD retains the 
requirements of EASA AD 2010-0146, which is superseded, requires 
inspection and, depending on findings, reinforcement of the 
pressurized bulkhead structure on extended population of aeroplanes. 
This AD also specifies that certain aeroplanes modified in 
accordance with SB 80-0081 up to Revision 2 need to be inspected 
and, depending on findings, reinforced as required by this AD.

2466.

identified in the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed AD will affect 28 products of U.S. 
registry. We also estimate that it would take about 1 work-hour 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 $2,380, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 88 work-hours and require parts costing $30,000, for a cost 
of $37,480 per product. We have no way of determining the number of 
products that may need these actions.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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),
    (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.

2. The FAA amends Sec.  39.13 by adding the following new AD:

Piaggio Aero Industries S.p.A: Docket No. FAA-2015-2466; Directorate 
Identifier 2015-CE-018-AD.

(a) Comments Due Date

    We must receive comments by August 20, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Piaggio Aero Industries S.p.A P-180 Model P-
180 airplanes, serial numbers (S/N) 1004 through 1033, certificated 
in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 53: Fuselage.

(e) Reason

    This AD was prompted by 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 the need to 
restore the safe fatigue life of the bulkhead structure. We are 
issuing this AD to correct the safe fatigue life of the airplane.

(f) Actions and Compliance

    (1) Unless already done, do the actions in paragraphs (f)(2) 
through (f)(4) of this AD at whichever of the following compliance 
times occurs later:
    (i) Within 1,500 hours time-in-service (TIS) after the effective 
date of this AD, but not to exceed 6,000 hours total hours TIS on 
the airplane; or
    (ii) Within 200 hours TIS after the effective date of this AD or 
6 months after the effective date of this AD, whichever occurs 
first.
    (2) Inspect (visually or using a standard endoscope) the forward 
pressurized bulkhead to verify presence of bulkhead reinforcement 
following Part A1 of the Accomplishment Instructions of Piaggio Aero 
Industries S.p.A. Service Bulletin 80-0081, Revision No. 3, dated: 
January 20, 2015.
    (i) If the inspection results indicate that the reinforcements 
are properly installed, ascertain (visually or by means of standard 
endoscope equipment) that there are no cracks or defects. If cracks 
or defects are identified, before further flight, repair using 
instructions from Piaggio Aero Industries as identified in Service 
Letter 80-0097.
    (ii) If the inspection results indicate that the reinforcements 
are not installed, reinforce the forward pressurized bulkhead 
following Part A2 of the Accomplishment Instructions of Piaggio Aero 
Industries S.p.A. Service Bulletin 80-0081, Revision No. 3, dated: 
January 20, 2015.
