ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 727–100 series airplanes. This AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. For certain airplanes, this AD requires repetitive inspections for cracking in stringers or frames until modification, and repair if necessary. We are issuing this AD to detect and correct cracking in stringers or frames originating at or near stringer-to-frame attachment fastener holes, which could result in reduced structural integrity of the airplane, and decompression of the cabin. DATES: This AD is effective July 28, 2014. SUMMARY: The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 28, 2014.

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 The Boeing Company Model 727–100 series airplanes. The NPRM published in the Federal Register on March 12, 2014 (79 FR 13931). The NPRM proposed actions intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. For certain airplanes, the NPRM proposed to require repetitive inspections for cracking in stringers or frames until modification, and repair if necessary. We are issuing this AD to detect and correct cracking in stringers or frames originating at or near stringer-to-frame attachment fastener holes, which could result in reduced structural integrity of the airplane, and decompression of the cabin. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 13931, March 12, 2014) 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 (79 FR 13931, March 12, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 13931, March 12, 2014). Costs of Compliance We estimate that this AD affects 2 airplanes of U.S. registry. We estimate the following costs to comply with this AD: pmangrum on DSK3VPTVN1PROD with RULES ESTIMATED COSTS Action Labor cost Parts cost Cost per product Inspections ........... 60 work-hours × $85 per hour = $5,100 per inspection cycle. $0 $5,100 per inspection cycle VerDate Mar<15>2010 14:40 Jun 20, 2014 Jkt 232001 PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 E:\FR\FM\23JNR1.SGM 23JNR1 Cost on U.S. operators $10,200 per inspection cycle. 35480 Federal Register / Vol. 79, No. 120 / Monday, June 23, 2014 / Rules and Regulations We estimate the following costs to do any necessary modifications that would be required based on the results of the inspections. We have no way of determining the number of aircraft that might need these modifications: ON-CONDITION COSTS Action Labor cost Parts cost Cost per product Modification .......... 600 work-hours × $85 per hour = $51,000 per inspection cycle ..... Up to $11,481 ............................. Up to $62,481 per modification. 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. pmangrum on DSK3VPTVN1PROD 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 to supersede AD 2003–05–03 (68 FR 11967, March 13, 2003). AD 2003– 05–03 applied to Bell Model 407 helicopters. The NPRM published in the Federal Register on July 12, 2013 (78 FR 41877). The NPRM proposed to retain the actions of AD 2003–05–03 requiring preflight checks and repetitive inspections for a crack in certain tailbooms that have been redesigned, replacing the tailboom if there is a crack, modifying and re-identifying certain tailbooms, installing an improved horizontal stabilizer assembly, and assigning a 5,000 hour TIS limit. The NPRM also proposed to require additional inspection requirements. The NPRM was prompted by Canadian AD No. CF–2008–04, dated January 11, 2008 (AD CF–2008–04), issued by Transport Canada Civil Aviation (TCAA), which is the aviation authority for Canada, to correct an unsafe condition for Bell Model 407 helicopters. TCAA advises that there have been several reports of cracks to the tailboom skin on the left side in the area of the horizontal stabilizer. AD CF– 2008–04 mandates new inspection requirements based on the manufacturer’s service information discussed in the ‘‘Related Service Information’’ section under SUPPLEMENTARY INFORMATION in the preamble of this final rule.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 727-100 series airplanes. This AD is intended 
to complete certain mandated programs intended to support the airplane 
reaching its limit of validity (LOV) of the engineering data that 
support the established structural maintenance program. For certain 
airplanes, this AD requires repetitive inspections for cracking in 
stringers or frames until modification, and repair if necessary. We are 
issuing this AD to detect and correct cracking in stringers or frames 
originating at or near stringer-to-frame attachment fastener holes, 
which could result in reduced structural integrity of the airplane, and 
decompression of the cabin.

DATES: This AD is effective July 28, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 28, 
2014.

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 The Boeing Company 
Model 727-100 series airplanes. The NPRM published in the Federal 
Register on March 12, 2014 (79 FR 13931). The NPRM proposed actions 
intended to complete certain mandated programs intended to support the 
airplane reaching its limit of validity (LOV) of the engineering data 
that support the established structural maintenance program. For 
certain airplanes, the NPRM proposed to require repetitive inspections 
for cracking in stringers or frames until modification, and repair if 
necessary. We are issuing this AD to detect and correct cracking in 
stringers or frames originating at or near stringer-to-frame attachment 
fastener holes, which could result in reduced structural integrity of 
the airplane, and decompression of the cabin.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 13931, March 12, 
2014) 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 (79 FR 13931, March 12, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 13931, March 12, 2014).

Costs of Compliance

    We estimate that this AD affects 2 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

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


[[Page 35480]]

    We estimate the following costs to do any necessary modifications 
that would be required based on the results of the inspections. We have 
no way of determining the number of aircraft that might need these 
modifications:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------

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.

List of Subjects in 14 CFR Part 39

(d) Subject

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

(e) Unsafe Condition

    This AD is intended to complete certain mandated programs 
intended to support the airplane reaching its limit of validity 
(LOV) of the engineering data that support the established 
structural maintenance program. We are issuing this AD to detect and 
correct cracking in stringers or frames originating at or near 
stringer-to-frame attachment fastener holes, which could result in 
reduced structural integrity of the airplane, and decompression of 
the cabin.

(f) Compliance

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

(g) Inspections

    Before the accumulation of 16,000 total flight cycles, or within 
3,000 flight cycles after the effective date of this AD, whichever 
occurs later, do a high frequency eddy current inspection and a 
general visual inspection for cracking in stringers and frames 
originating at or near stringer-to-frame attachment fastener holes, 
in accordance with the Accomplishment Instructions of Boeing Service 
Bulletin 727-53-0041, Revision 6, dated September 5, 1991. Repeat 
the inspections thereafter at intervals not to exceed 6,000 flight 
cycles until the modification specified by paragraph (h) of this AD 
is accomplished. If any crack is found during any inspection 
required by this paragraph: Before further flight, repair or modify 
the affected stringer-to-frame attachment locations, in accordance 
with Part V, ``Repair Data,'' of the Accomplishment Instructions of 
Boeing Service Bulletin 727-53-0041, Revision 6, dated September 5, 
1991.

(h) Modification

    Modifying the affected stringer-to-frame attachment locations, 
in accordance with Part IV, ``Preventive Modification Data,'' of the 
Accomplishment Instructions of Boeing Service Bulletin 727-53-0041, 
Revision 6, dated September 5, 1991, terminates the repetitive 
inspections required by paragraph (g) of this AD.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles Aircraft Certification Office 
(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 (j) of this AD. 
Information may be emailed to: 9-ANM-LAACO-AMOC-REQUESTS@faa.gov.
    (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.

[[Page 35481]]

    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD if it is approved by the 
Boeing Commercial Airplanes Organization Designation Authorization 
(ODA) that has been authorized by the Manager, Los Angeles ACO, to 
make those findings. For a repair method to be approved, the repair 
must meet the certification basis of the airplane, and the approval 
must specifically refer to this AD.
