ACTION: Final rule. AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767–300 series airplanes. This AD was prompted by a report that certain airplanes might not have reinforcement straps installed on the center overhead stowage bins in the passenger compartment, and some PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 ADDRESSES: FOR FURTHER INFORMATION CONTACT: Sarah Piccola, Aerospace Engineer, Cabin Safety and Environmental Systems Branch, ANM–150S, FAA, Seattle Aircraft Certification Office, 1601 Lind Avenue SW., Renton, Washington 98057–3356; phone: 425– 917–6483; fax: 425–917–6590; email: sarah.piccola@faa.gov. SUPPLEMENTARY INFORMATION: E:\FR\FM\01MYR1.SGM 01MYR1 Federal Register / Vol. 78, No. 84 / Wednesday, May 1, 2013 / Rules and Regulations Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM published in the Federal Register on October 16, 2012 (77 FR 63266). That NPRM proposed to require, for certain airplanes, performing an inspection of reinforcement straps to ensure they are correctly bonded to the center overhead stowage bins, and bonding the reinforcement straps to the center overhead stowage bins if necessary. For certain airplanes, that NPRM also proposed installing reinforcement straps on the center overhead stowage bins. wreier-aviles on DSK5TPTVN1PROD with RULES Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the proposal (77 FR 63266, October 16, 2012) and the FAA’s response to each comment. Aviation Partners Boeing stated that the installation of winglets per supplemental type certificate (STC) ST01920SE (https://rgl.faa.gov/ Regulatory_and_Guidance_Library/ rgstc.nsf/0/ 59027f43b9a7486e86257b1d006591ee/ $FILE/ST01920SE.pdf) does not affect the accomplishment of the manufacturer’s service instructions. Request To Remove Reference to ‘‘Inflight Turbulence’’ Boeing requested that the potential injury statement that appears in the Summary paragraph, Discussion paragraph, and paragraph (e), ‘‘Unsafe Condition,’’ of the NPRM (77 FR 63266, October 16, 2012) be revised to remove the reference to in-flight turbulence. Boeing suggested that the potential injury statement should specify the requirements associated with section 25.561(b)(3)(ii) (‘‘9.0g Forward loads’’) of the Federal Aviation Regulations (14 CFR 25.561). Boeing stated that Boeing Special Attention Service Bulletin 767– 25–0520, dated February 8, 2012, and associated certification data, refer only to 9.0g forward loads and not in-flight loads. Based on the reasons provided by the commenter, we agree to revise the potential injury statement by deleting the reference to ‘‘in-flight turbulence’’ and including a reference to 9g forward loads. The potential injury statement in VerDate Mar<15>2010 14:02 Apr 30, 2013 Jkt 229001 this AD states ‘‘We are issuing this AD to prevent missing or incorrectly bonded reinforcement straps, which could result in the center overhead stowage bins breaking loose at forward load levels less than 9g during an emergency landing, causing injury to passengers and delaying emergency evacuation.’’ The revised potential injury statement appears in the Summary paragraph and paragraph (e) of this AD. The potential injury statement is not restated in the Discussion paragraph of this AD, so no change is needed to that paragraph. Request To Clarify Precipatory Event Boeing requested that paragraph (e), ‘‘Unsafe Condition,’’ in the NPRM (77 FR 63266, October 16, 2012) be revised so the first sentence states that ‘‘certain airplanes (1) may not have reinforcement straps installed and (2) may not have been bonded at some center overhead stowage bin locations.’’ The suggested text is from Boeing Special Attention Service Bulletin 767– 25–0520, dated February 8, 2012. Boeing noted that the NPRM does not address condition (1) and is not consistent with condition (2). We agree with Boeing’s request to revise the wording that describes what prompted this AD. Boeing’s suggested changes clarify the conditions that operators may encounter when complying with the actions required by this AD. The revised statement appears in the Summary paragraph and paragraph (e) of this AD. Request To Revise the ‘‘Relevant Service Information’’ Paragraph Boeing requested that the text in the ‘‘Relevant Service Information’’ paragraph of the NPRM (77 FR 63266, October 16, 2012) be changed so the language within the NPRM and the language between the NPRM and Boeing Special Attention Service Bulletin 767– 25–0520, dated February 8, 2012, is consistent. Boeing suggested that in the second sentence of that paragraph, beginning with ‘‘For certain airplanes, this service bulletin describes procedures for general visual and detailed inspection of the existing reinforcement straps installed on the center overhead storage bins . . ..’’ ‘‘storage’’ be changed to ‘‘stowage.’’ Boeing also suggested that the third sentence of that paragraph, beginning with ‘‘For airplanes on which the straps PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 25375 are incorrectly bonded . . . .’’ be revised to delete ‘‘are incorrectly bonded’’ and insert ‘‘may not be bonded or were inadvertently missed.’’ Boeing also requested that the last sentence in the ‘‘Relevant Service Information’’ paragraph be removed and the sentence prior to that one, beginning with ‘‘For airplanes on which the straps are incorrectly bonded, this service bulletin describes procedures for bonding the reinforcement straps . . . .’’ be revised to read, ‘‘. . . bonding and installation of the reinforcement straps . . . .’’ Boeing stated that these changes would provide clarity to the operators. We agree that the suggestions made by the commenter provide a more accurate description of the information in Boeing Special Attention Service Bulletin 767– 25–0520, dated February 8, 2012; however, the ‘‘Relevant Service Information’’ paragraph is not restated in this AD, so no change has been made to this AD in this regard. Explanation of Change Made to This AD We have added a new paragraph (h)(3) to this final rule to allow delegation of repairs to the Boeing Commercial Airplanes Organization Designation Authorization (ODA). Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously– and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (77 FR 63266, October 16, 2012) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (77 FR 63266, October 16, 2012). We also determined that these changes will not increase the economic burden on any operator or increase the scope of the 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: E:\FR\FM\01MYR1.SGM 01MYR1 25376 Federal Register / Vol. 78, No. 84 / Wednesday, May 1, 2013 / Rules and Regulations ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Group 1 and Group 2 Airplanes: General Visual Inspection for Correct Bonding. Group 1 and Group 3 Airplanes: Install Reinforcement Straps. 2 work-hours × $85 per hour = $170 .. $0 .......................... $170 ...................... $340 (2 airplanes). 7 work-hours × $85 per hour = $595 .. $1,277 or $1,746 .. $1,872 or $2,341 .. Up to $4,682 (2 airplanes). We estimate the following costs to do any necessary repairs that would be required based on the results of the inspection. We have no way of determining the number of aircraft that might need this repair: ON-CONDITION COSTS Action Labor cost Group 1 and Group 2 Airplanes: Bonding Existing Reinforcement Straps to the Center Overhead Stowage Bins. Between 7 and 12 work-hours × $85 per hour = $595 to $1,020. According to the manufacturer, some of the costs of this 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. wreier-aviles on DSK5TPTVN1PROD with RULES 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. VerDate Mar<15>2010 14:02 Apr 30, 2013 Jkt 229001 $0 Between $595 and $1,020. 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. (b) Affected ADs List of Subjects in 14 CFR Part 39 This AD was prompted by a report that certain airplanes might not have reinforcement straps installed on the center overhead stowage bins in the passenger compartment, and some installed reinforcement straps might not have been bonded. We are issuing this AD to prevent missing or incorrectly bonded reinforcement straps, which could result in the center overhead stowage bins breaking loose at forward load levels less than 9g during an emergency landing, causing injury to passengers and delaying emergency evacuation.

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 767-300 series airplanes. This AD was prompted 
by a report that certain airplanes might not have reinforcement straps 
installed on the center overhead stowage bins in the passenger 
compartment, and some installed reinforcement straps might not have 
been bonded. For certain airplanes, this AD requires performing an 
inspection of reinforcement straps to ensure they are correctly bonded 
to the center overhead stowage bins, and bonding the reinforcement 
straps to the center overhead stowage bins if necessary. For certain 
airplanes, this AD requires installing reinforcement straps on the 
center overhead stowage bins. We are issuing this AD to prevent missing 
or incorrectly bonded reinforcement straps, which could result in the 
center overhead stowage bins breaking loose at forward load levels less 
than 9g during an emergency landing, causing injury to passengers and 
delaying emergency evacuation.

DATES: This AD is effective June 5, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of June 5, 2013.

SUPPLEMENTARY INFORMATION: 

[[Page 25375]]

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM published in the Federal Register on October 16, 2012 (77 FR 
63266). That NPRM proposed to require, for certain airplanes, 
performing an inspection of reinforcement straps to ensure they are 
correctly bonded to the center overhead stowage bins, and bonding the 
reinforcement straps to the center overhead stowage bins if necessary. 
For certain airplanes, that NPRM also proposed installing reinforcement 
straps on the center overhead stowage bins.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the proposal 
(77 FR 63266, October 16, 2012) and the FAA's response to each comment.
    Aviation Partners Boeing stated that the installation of winglets 
per supplemental type certificate (STC) ST01920SE (https://rgl.faa.gov/
Regulatory--and--Guidance--Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect 
the accomplishment of the manufacturer's service instructions.

Request To Remove Reference to ``In-flight Turbulence''

    Boeing requested that the potential injury statement that appears 
in the Summary paragraph, Discussion paragraph, and paragraph (e), 
``Unsafe Condition,'' of the NPRM (77 FR 63266, October 16, 2012) be 
revised to remove the reference to in-flight turbulence. Boeing 
suggested that the potential injury statement should specify the 
requirements associated with section 25.561(b)(3)(ii) (``9.0g Forward 
loads'') of the Federal Aviation Regulations (14 CFR 25.561). Boeing 
stated that Boeing Special Attention Service Bulletin 767-25-0520, 
dated February 8, 2012, and associated certification data, refer only 
to 9.0g forward loads and not in-flight loads.
    Based on the reasons provided by the commenter, we agree to revise 
the potential injury statement by deleting the reference to ``in-flight 
turbulence'' and including a reference to 9g forward loads. The 
potential injury statement in this AD states ``We are issuing this AD 
to prevent missing or incorrectly bonded reinforcement straps, which 
could result in the center overhead stowage bins breaking loose at 
forward load levels less than 9g during an emergency landing, causing 
injury to passengers and delaying emergency evacuation.''
    The revised potential injury statement appears in the Summary 
paragraph and paragraph (e) of this AD. The potential injury statement 
is not restated in the Discussion paragraph of this AD, so no change is 
needed to that paragraph.

Request To Clarify Precipatory Event

    Boeing requested that paragraph (e), ``Unsafe Condition,'' in the 
NPRM (77 FR 63266, October 16, 2012) be revised so the first sentence 
states that ``certain airplanes (1) may not have reinforcement straps 
installed and (2) may not have been bonded at some center overhead 
stowage bin locations.'' The suggested text is from Boeing Special 
Attention Service Bulletin 767-25-0520, dated February 8, 2012. Boeing 
noted that the NPRM does not address condition (1) and is not 
consistent with condition (2).
    We agree with Boeing's request to revise the wording that describes 
what prompted this AD. Boeing's suggested changes clarify the 
conditions that operators may encounter when complying with the actions 
required by this AD. The revised statement appears in the Summary 
paragraph and paragraph (e) of this AD.

Request To Revise the ``Relevant Service Information'' Paragraph

    Boeing requested that the text in the ``Relevant Service 
Information'' paragraph of the NPRM (77 FR 63266, October 16, 2012) be 
changed so the language within the NPRM and the language between the 
NPRM and Boeing Special Attention Service Bulletin 767-25-0520, dated 
February 8, 2012, is consistent. Boeing suggested that in the second 
sentence of that paragraph, beginning with ``For certain airplanes, 
this service bulletin describes procedures for general visual and 
detailed inspection of the existing reinforcement straps installed on 
the center overhead storage bins . . ..'' ``storage'' be changed to 
``stowage.'' Boeing also suggested that the third sentence of that 
paragraph, beginning with ``For airplanes on which the straps are 
incorrectly bonded . . . .'' be revised to delete ``are incorrectly 
bonded'' and insert ``may not be bonded or were inadvertently missed.''
    Boeing also requested that the last sentence in the ``Relevant 
Service Information'' paragraph be removed and the sentence prior to 
that one, beginning with ``For airplanes on which the straps are 
incorrectly bonded, this service bulletin describes procedures for 
bonding the reinforcement straps . . . .'' be revised to read, ``. . . 
bonding and installation of the reinforcement straps . . . .'' Boeing 
stated that these changes would provide clarity to the operators.
    We agree that the suggestions made by the commenter provide a more 
accurate description of the information in Boeing Special Attention 
Service Bulletin 767-25-0520, dated February 8, 2012; however, the 
``Relevant Service Information'' paragraph is not restated in this AD, 
so no change has been made to this AD in this regard.

Explanation of Change Made to This AD

    We have added a new paragraph (h)(3) to this final rule to allow 
delegation of repairs to the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA).

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously-and minor editorial 
changes. We have determined that these minor changes:
     [Agr]re consistent with the intent that was proposed in 
the NPRM (77 FR 63266, October 16, 2012) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 63266, October 16, 2012).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of the 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:

[[Page 25376]]



                                                 Estimated Costs

 General Visual Inspection for     per hour = $170.                                            airplanes).
 Correct Bonding.

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

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the inspection. We have no 
way of determining the number of aircraft that might need this repair:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                 Action                           Labor cost            Parts cost         Cost per  product
----------------------------------------------------------------------------------------------------------------
Group 1 and Group 2 Airplanes: Bonding    Between 7 and 12 work-                  $0  Between $595 and $1,020.
 Existing Reinforcement Straps to the      hours x $85 per hour =
 Center Overhead Stowage Bins.             $595 to $1,020.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this 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

    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.
