ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 188 series airplanes. This AD was prompted by an evaluation by the design approval holder (DAH) indicating that the circumferential fuselage splice at fuselage-station (FS) 695 is subject to widespread fatigue damage (WFD). This AD requires an inspection for corrosion and previous repairs, severed stringers, cracking, and loose or distressed fasteners of the forward and aft ends of the stringer splices of certain stringers, inspection for cracking and modification of certain fastener holes common to the stringer and splice member at the forward and aft ends of the splice, and related investigative and corrective actions if necessary. We are issuing this AD to prevent loss of residual strength of the circumferential fuselage splice at FS 695, which could lead to rapid decompression of the cabin and potential loss of the airplane. DATES: This AD is effective December 10, 2015. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of December 10, 2015.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 188 series airplanes. The NPRM published in the Federal Register on May 28, 2015 (80 FR 30391). The NPRM was prompted by an evaluation by the DAH indicating that a certain circumferential fuselage splice is subject to WFD. The NPRM proposed to require an inspection for corrosion and previous repairs, severed stringers, cracking, and loose or distressed fasteners of the forward and aft ends of the stringer splices of certain stringers, inspection for cracking and modification of certain fastener holes common to the stringer and splice member at the forward and aft ends of the splice, and related investigative and corrective actions if necessary. We are issuing this AD to prevent loss of PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 residual strength of a certain circumferential fuselage splice, which could lead to rapid decompression of the cabin and potential loss of the airplane. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (80 FR 30391, May 28, 2015) or on the determination of the cost to the public. Conclusion We reviewed the relevant data and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (80 FR 30391, May 28, 2015) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (80 FR 30391, May 28, 2015). Related Service Information Under 1 CFR Part 51 We reviewed Lockheed Martin Electra Service Bulletin 88/SB–722, dated April 30, 2014. This service bulletin describes procedures for doing the following actions: • A general visual inspection (GVI) for corrosion and previous repairs, severed stringers, cracking, and loose or distressed fasteners of the forward and aft ends of the stringer splices of stringers 1–7 and 66–72, and corrective actions if necessary. • At stringers 1–7 and 66–72, removing the four rivets common to the stringer and splice member at the forward and aft ends of the splice and doing a bolt hole eddy current (BHEC) inspection or an equivalent inspection procedure for cracking in each of the fastener holes, and corrective actions if necessary. • Corrective actions for cracked holes include reaming to the maximum permissible hole diameter of the next larger size rivet. If a crack indication remains after reaming, this service information specifies repairing the cracked stringer. • If a severed stringer is found during the GVI, doing related investigative actions of an eddy current surface scan inspection for cracking of the fuselage skin at the skin-to-stringer attachments immediately forward and aft of the stringer break and confirming skin cracks with a dye penetrant inspection. Corrective actions include repairing the severed stringer or skin cracks. E:\FR\FM\05NOR1.SGM 05NOR1 Federal Register / Vol. 80, No. 214 / Thursday, November 5, 2015 / Rules and Regulations • For holes without crack indications, other specified actions include modifying the fastener holes by reaming to a certain maximum permissible hole diameter of the same size rivet and installing replacement fasteners; or if the original hole is larger than the maximum permissible diameter, installing the next rivet size and type. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section of this AD. 68433 Costs of Compliance We estimate that this AD affects 4 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Inspections and Modification ............ 18 work-hours × $85 per hour = $1,530 ....................... $5,000 $6,530 $26,120 under the criteria of the Regulatory Flexibility Act. We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in 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. jstallworth on DSK7TPTVN1PROD with RULES Regulatory Findings This AD will not have federalism implications under Executive Order 13132.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus Model A318, A319, and A320 series airplanes. The NPRM published in the Federal Register on March 5, 2015 (80 FR 11964). The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2014–0141, dated June 4, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus Model A318, A319, and A320 series airplanes. The MCAI states: During an A320–200 77T main landing gear (MLG) fatigue test by Messier BugattiDowty (MBD), an upper cardan was found with a crack, emanating from the grease hole/ main lug intersection. The affected upper cardan, Part Number (P/N) 201163620, is listed in the applicable Airworthiness Limitations Section (ALS) Part 1 with a demonstrated fatigue life of 60,000 landings. This condition, if not corrected, could lead to MLG upper cardan failure, possibly resulting in MLG collapse and subsequent damage to the aeroplane and injury to occupants. Prompted by these findings and further to analysis, it has been decided to reduce the life limit for certain installations of the P/N 201163620 MLG upper cardan. For the reasons described above, this AD requires implementation of the new life limits, as applicable, and replacement of any affected MLG upper cardan units that have already exceeded the reduced limit. The reduced life limits for the affected MLG upper cardan are expected to be incorporated in a next revision of the Airbus A318/A319/A320/A321 ALS Part 1.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 
188 series airplanes. This AD was prompted by an evaluation by the 
design approval holder (DAH) indicating that the circumferential 
fuselage splice at fuselage-station (FS) 695 is subject to widespread 
fatigue damage (WFD). This AD requires an inspection for corrosion and 
previous repairs, severed stringers, cracking, and loose or distressed 
fasteners of the forward and aft ends of the stringer splices of 
certain stringers, inspection for cracking and modification of certain 
fastener holes common to the stringer and splice member at the forward 
and aft ends of the splice, and related investigative and corrective 
actions if necessary. We are issuing this AD to prevent loss of 
residual strength of the circumferential fuselage splice at FS 695, 
which could lead to rapid decompression of the cabin and potential loss 
of the airplane.

DATES: This AD is effective December 10, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 10, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Lockheed Martin 
Corporation/Lockheed Martin Aeronautics Company Model 188 series 
airplanes. The NPRM published in the Federal Register on May 28, 2015 
(80 FR 30391). The NPRM was prompted by an evaluation by the DAH 
indicating that a certain circumferential fuselage splice is subject to 
WFD. The NPRM proposed to require an inspection for corrosion and 
previous repairs, severed stringers, cracking, and loose or distressed 
fasteners of the forward and aft ends of the stringer splices of 
certain stringers, inspection for cracking and modification of certain 
fastener holes common to the stringer and splice member at the forward 
and aft ends of the splice, and related investigative and corrective 
actions if necessary. We are issuing this AD to prevent loss of 
residual strength of a certain circumferential fuselage splice, which 
could lead to rapid decompression of the cabin and potential loss of 
the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 30391, May 28, 
2015) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 30391, May 28, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 30391, May 28, 2015).

Related Service Information Under 1 CFR Part 51

    We reviewed Lockheed Martin Electra Service Bulletin 88/SB-722, 
dated April 30, 2014. This service bulletin describes procedures for 
doing the following actions:
     A general visual inspection (GVI) for corrosion and 
previous repairs, severed stringers, cracking, and loose or distressed 
fasteners of the forward and aft ends of the stringer splices of 
stringers 1-7 and 66-72, and corrective actions if necessary.
     At stringers 1-7 and 66-72, removing the four rivets 
common to the stringer and splice member at the forward and aft ends of 
the splice and doing a bolt hole eddy current (BHEC) inspection or an 
equivalent inspection procedure for cracking in each of the fastener 
holes, and corrective actions if necessary.
     Corrective actions for cracked holes include reaming to 
the maximum permissible hole diameter of the next larger size rivet. If 
a crack indication remains after reaming, this service information 
specifies repairing the cracked stringer.
     If a severed stringer is found during the GVI, doing 
related investigative actions of an eddy current surface scan 
inspection for cracking of the fuselage skin at the skin-to-stringer 
attachments immediately forward and aft of the stringer break and 
confirming skin cracks with a dye penetrant inspection. Corrective 
actions include repairing the severed stringer or skin cracks.

[[Page 68433]]

     For holes without crack indications, other specified 
actions include modifying the fastener holes by reaming to a certain 
maximum permissible hole diameter of the same size rivet and installing 
replacement fasteners; or if the original hole is larger than the 
maximum permissible diameter, installing the next rivet size and type.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section of this 
AD.

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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

    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 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2015-22-07 Lockheed Martin Corporation/Lockheed Martin Aeronautics 
Company: Amendment 39-18312 ; Docket No. FAA-2015-1425; Directorate 
Identifier 2014-NM-185-AD.

(a) Effective Date

    This AD is effective December 10, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Lockheed Martin Corporation/Lockheed Martin 
Aeronautics Company Model 188A and 188C airplanes, certificated in 
any category, serial numbers 1001 and subsequent.

(d) Subject

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

(e) Unsafe Condition

    This AD was prompted by an evaluation by the design approval 
holder (DAH) indicating that the circumferential fuselage splice at 
fuselage-station (FS) 695 is subject to widespread fatigue damage 
(WFD). We are issuing this AD to prevent loss of residual strength 
of the circumferential fuselage splice at FS 695, which could lead 
to rapid decompression of the cabin and potential loss of the 
airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Inspections, Modification, Related Investigative Actions, and 
Corrective Actions

    Before the accumulation of 38,200 total flight hours or within 
30 days after the effective date of this AD, whichever occurs later: 
Do a general visual inspection for corrosion and previous repairs, 
severed stringers, cracking, and loose or distressed fasteners of 
the forward and aft ends of the stringer splices of stringers 1-7 
and 66-72; remove the four rivets common to the stringer and splice 
member at the forward and aft ends of the splice and do a bolt hole 
eddy current inspection or an equivalent inspection procedure for 
cracking in each of the fastener holes; modify the fastener holes; 
and do all applicable related investigative and corrective actions 
and other specified actions; in accordance with the Accomplishment 
Instructions of Lockheed Martin Electra Service Bulletin 88/SB-722, 
dated April 30, 2014, except as specified in paragraph (h) of this 
AD. Do all applicable related investigative and corrective actions 
and other specified actions before further flight. If any repairs 
exceed the repair limits specified in Lockheed Martin Electra 
Service Bulletin 88/SB-722, dated April 30, 2014, before further 
flight, repair using a method approved in accordance with the 
procedures specified in paragraph (j) of this AD.

(h) Corrective Action

    (1) If, during any inspection required by paragraph (g) of this 
AD, any corrosion or previous repair is found, before further 
flight, repair using a method approved in accordance with the 
procedures specified in paragraph (j) of this AD.
    (2) If, during any inspection required by paragraph (g) of this 
AD, any loose or distressed fastener is found, before further 
flight, repair using a method approved in accordance with the 
procedures specified in paragraph (j) of this AD.

(i) Exception

    Although Lockheed Martin Electra Service Bulletin 88/SB-722, 
dated April 30, 2014,

[[Page 68434]]

specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Atlanta ACO, FAA, has the authority to approve 
AMOCs for this AD, if requested using the procedures found in 14 CFR 
39.19. In accordance with 14 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the manager of the 
ACO, send it to the attention of the person identified in paragraph 
(k) of this AD.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
