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 747–100, 747–100B, 747–100B SUD, 747–200B, 747–300, 747SR, and 747SP series airplanes. The NPRM published in the Federal Register on May 5, 2015 (80 FR 25630). The NPRM was prompted by an evaluation by the DAH indicating that certain fuselage PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 72573 skin lap joints are subject to WFD. The NPRM proposed to require repetitive post-modification inspections for cracking of the skin or internal doubler along the edge fastener rows of the modification, and repair if necessary. We are issuing this AD to detect and correct fatigue cracking in certain fuselage skin lap joints, which could result in rapid depressurization of the airplane. Comments We gave the public the opportunity to participate in developing this AD. The following presents the comments received on the NPRM (80 FR 25630, May 5, 2015) and the FAA’s response to each comment. Request To Remove Warranty Statement Boeing requested that we remove the statement that ‘‘some of the costs of this proposed AD may be covered under warranty’’ in the Costs of Compliance section of the NPRM (80 FR 25630, May 5, 2015). Boeing stated that the actions in the NPRM are not covered by warranty. We agree with the commenter’s request. We have revised the Costs of Compliance section of this final rule accordingly. Request To Revise Paragraph Headings Boeing requested that we revise the headings of paragraphs (g), (h), (j), and (k) of the proposed AD (80 FR 25630, May 5, 2015) by removing reference to the inspections as ‘‘repetitive’’ or ‘‘initial.’’ Boeing stated that these revisions will provide consistency among paragraph headings because paragraphs (g), (j), and (k) of the proposed AD do not have an initial inspection program, yet paragraph (h) of the proposed AD has only an initial inspection. We acknowledge the commenter’s concern and agree to clarify the headings. We do not presume that the term ‘‘repetitive’’ necessarily excludes the initial action. An action cannot be repeated without accomplishment of the initial action. In addition, in many ADs we use the term ‘‘repetitive’’ actions for paragraphs that include the initial action and repetitive actions. Paragraphs (g), (j), and (k) of this AD include both a sentence specifying the initial inspection and a sentence specifying the repetitive inspections. We have not changed this AD in this regard. Request To Clarify Compliance Time Boeing requested that we clarify the compliance time in paragraphs (g), (h), (j), and (k) of the proposed AD (80 FR E:\FR\FM\20NOR1.SGM 20NOR1 72574 Federal Register / Vol. 80, No. 224 / Friday, November 20, 2015 / Rules and Regulations 25630, May 5, 2015) by revising ‘‘at the applicable time’’ to ‘‘at the applicable time and repeat intervals.’’ Boeing stated that these revisions would clarify that the applicable time also includes the repeat intervals per Boeing Alert Service Bulletin 747–53A2367, Revision 5, dated July 8, 2014. We do not agree to combine the initial inspection and the repetitive inspection times into one statement because ADs typically call out initial inspections and repetitive inspections in separate sentences. Paragraph (h) of this AD specifies only an initial inspection. Paragraphs (g), (j), and (k) of this AD specifies an initial inspection and states that the repetitive inspections are for the unrepaired areas, which are to be done at the applicable times specified in Boeing Alert Service Bulletin 747– 53A2367, Revision 5, dated July 8, 2014. We have not changed this AD in this regard. tkelley on DSK3SPTVN1PROD with RULES Request To Delete the Unrepaired Area Statement From Paragraphs (g) (j) and (k) of the Proposed AD (80 FR 25630, May 5, 2015) Boeing requested that we delete the last sentence in paragraphs (g), (j), and (k) of the proposed AD (80 FR 25630, May 5, 2015), which states ‘‘In unrepaired areas, repeat the . . . inspections for cracks . . . .’’ Boeing stated that the sentence is confusing as the unrepaired area case is actually for no cracks found in the modification area after doing the inspection as specified in the applicable tables 3, 5, and 6 of Boeing Alert Service Bulletin 747– 53A2367, Revision 5, dated July 8, 2014. Boeing explained that the proposed AD wording may cause confusion when information is provided in a different format than the service bulletin tables. We do not agree with the commenter’s request because the text ‘‘in unrepaired areas’’ matches the text in Boeing Alert Service Bulletin 747–53A2367, Revision 5, dated July 8, 2014. Paragraphs (g), (j), and (k) of this AD specify doing actions at the applicable time specified in tables 3, 5, and 6 of paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 747–53A2367, Revision 5, dated July 8, 2014. In these tables, the compliance time is specified for the actions required for the unrepaired area. We have not revised this AD in this regard. Request To Combine Paragraphs Boeing requested that we combine paragraphs (h) and (i) of the proposed AD (80 FR 25630, May 5, 2015) by deleting paragraph (i) of the proposed AD and revising paragraph (h) of the proposed AD from ‘‘at the applicable VerDate Sep<11>2014 17:28 Nov 19, 2015 Jkt 238001 time’’ to ‘‘at the applicable time and repeat intervals.’’ Boeing explained that it is confusing to have separate paragraphs address initial and repetitive inspections for a particular aircraft as both initial and repetitive inspections are addressed within table 4 of Boeing Alert Service Bulletin 747–53A2367, Revision 5, dated July 8, 2014. We acknowledge that table 4 of Boeing Alert Service Bulletin 747– 53A2367, Revision 5, dated July 8, 2014, contains compliance times for both initial and repetitive inspections. However, we do not agree with the commenter’s request because the AD includes separate paragraphs in order to clarify the repetitive inspection intervals. For the initial inspections, table 4 of paragraph 1.E., ‘‘Compliance,’’ of Boeing Alert Service Bulletin 747– 53A2367, Revision 5, dated July 8, 2014, specifies two crack conditions, which are based on the number of fight cycles on the airplane since stringer 6 external doublers were installed. To aid the operators in determining which repetitive inspection(s) they are required to do, this AD provides the repetitive inspections (as restated from the NPRM (80 FR 25630, May 5, 2015)), depending on the applicable condition, in separate repetitive inspection paragraphs (paragraphs (i)(1) and (i)(2) of this AD). We have not changed this AD in this regard. Request To Revise External Inspection Wording Boeing requested that we remove the word ‘‘external’’ from paragraph (h) of the proposed AD (80 FR 25630, May 5, 2015), which specified ‘‘external detailed, low frequency eddy current, and high frequency eddy current inspections.’’ Boeing explained that if paragraphs (h) and (i) of the proposed AD are combined, both external and internal detailed inspections are required. Boeing stated that removing ‘‘external’’ from the inspection direction would therefore cover all airplane conditions. As stated previously, we do not agree to combine paragraphs (h) and (i) of this AD into one paragraph. Therefore, the terminology in paragraph (h) of this AD matches Boeing Alert Service Bulletin 747–53A2367, Revision 5, dated July 8, 2014, which specifies doing external detailed, low frequency eddy current (LFEC), and high frequency eddy current (HFEC) inspections for cracks. We have not changed this AD in this regard. PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 Request To Revise Headings of Paragraphs (h), (i), and (j) of the Proposed AD (80 FR 25630, May 5, 2015) Boeing requested that we revise the headings of paragraphs (h), (i), and (j) of the proposed AD (80 FR 25630, May 5, 2015) by adding a reference to the applicable service information. Boeing stated that these changes will add consistency among paragraphs (h), (i), and (j) of the proposed AD in identifying an installed external doubler modification. We agree with the commenter’s request. We have revised the headings of paragraphs (h), (i), and (j) of this AD accordingly. Request To Correct Typographical Error Boeing noted that a phrase describing the major action in paragraph (j) of the proposed AD (80 FR 25630, May 5, 2015) was duplicated and asked that we correct this. We agree with the commenter’s request. We have revised paragraph (j) of this AD accordingly. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this 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 (80 FR 25630, May 5, 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 25630, May 5, 2015). We also determined that these changes will not increase the economic burden on any operator or increase the scope of this AD. Related Service Information Under 1 CFR Part 51 We reviewed Boeing Alert Service Bulletin 747–53A2367, Revision 5, dated July 8, 2014. This service information describes procedures for inspections and repair for cracks in the skin and doublers along the edge fastener rows of modifications in the fuselage. 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. E:\FR\FM\20NOR1.SGM 20NOR1 Federal Register / Vol. 80, No. 224 / Friday, November 20, 2015 / Rules and Regulations Costs of Compliance 72575 We estimate the following costs to comply with this AD: We estimate that this AD affects 50 airplanes of U.S. registry. ESTIMATED COSTS Action Labor cost Parts cost Post-modification inspection ........ 124 work-hours × $85 per hour = $10,540 per inspection cycle. $0 We have received no definitive data that would enable us to provide cost estimates for the on-condition actions specified in this AD. List of Subjects in 14 CFR Part 39 Authority for This Rulemaking Adoption of the Amendment 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. Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. tkelley on DSK3SPTVN1PROD 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. 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. 17:28 Nov 19, 2015 1.

ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) flightcrew oxygen mask regulators as installed on, but not limited to, various transport and small airplanes. This AD was prompted by a report that improper maintenance on oxygen mask regulators was found. This AD requires the identification and replacement of all potentially affected units. This AD also requires installation of a placard and revision of the airplane flight manual to include an operational procedure for use in case of depressurization. We are issuing this AD to detect and correct affected oxygen mask regulators, which could lead to inadequate protection to the affected flightcrew against hypoxia.

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 747-100, 747-100B, 747-100B SUD, 747-200B, 
747-300, 747SR, and 747SP series airplanes. This AD was prompted by an 
evaluation by the design approval holder (DAH) indicating that certain 
fuselage skin lap joints are subject to widespread fatigue damage 
(WFD). This AD requires repetitive post-modification inspections for 
cracking of the skin or internal doubler along the edge fastener rows 
of the modification, and repair if necessary. We are issuing this AD to 
detect and correct fatigue cracking in certain fuselage skin lap 
joints, which could result in rapid depressurization of the airplane.

DATES: This AD is effective December 28, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 28, 
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 The Boeing Company 
Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-300, 747SR, and 
747SP series airplanes. The NPRM published in the Federal Register on 
May 5, 2015 (80 FR 25630). The NPRM was prompted by an evaluation by 
the DAH indicating that certain fuselage skin lap joints are subject to 
WFD. The NPRM proposed to require repetitive post-modification 
inspections for cracking of the skin or internal doubler along the edge 
fastener rows of the modification, and repair if necessary. We are 
issuing this AD to detect and correct fatigue cracking in certain 
fuselage skin lap joints, which could result in rapid depressurization 
of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (80 
FR 25630, May 5, 2015) and the FAA's response to each comment.

Request To Remove Warranty Statement

    Boeing requested that we remove the statement that ``some of the 
costs of this proposed AD may be covered under warranty'' in the Costs 
of Compliance section of the NPRM (80 FR 25630, May 5, 2015). Boeing 
stated that the actions in the NPRM are not covered by warranty.
    We agree with the commenter's request. We have revised the Costs of 
Compliance section of this final rule accordingly.

Request To Revise Paragraph Headings

    Boeing requested that we revise the headings of paragraphs (g), 
(h), (j), and (k) of the proposed AD (80 FR 25630, May 5, 2015) by 
removing reference to the inspections as ``repetitive'' or ``initial.'' 
Boeing stated that these revisions will provide consistency among 
paragraph headings because paragraphs (g), (j), and (k) of the proposed 
AD do not have an initial inspection program, yet paragraph (h) of the 
proposed AD has only an initial inspection.
    We acknowledge the commenter's concern and agree to clarify the 
headings. We do not presume that the term ``repetitive'' necessarily 
excludes the initial action. An action cannot be repeated without 
accomplishment of the initial action. In addition, in many ADs we use 
the term ``repetitive'' actions for paragraphs that include the initial 
action and repetitive actions. Paragraphs (g), (j), and (k) of this AD 
include both a sentence specifying the initial inspection and a 
sentence specifying the repetitive inspections. We have not changed 
this AD in this regard.

Request To Clarify Compliance Time

    Boeing requested that we clarify the compliance time in paragraphs 
(g), (h), (j), and (k) of the proposed AD (80 FR

[[Page 72574]]

25630, May 5, 2015) by revising ``at the applicable time'' to ``at the 
applicable time and repeat intervals.'' Boeing stated that these 
revisions would clarify that the applicable time also includes the 
repeat intervals per Boeing Alert Service Bulletin 747-53A2367, 
Revision 5, dated July 8, 2014.
    We do not agree to combine the initial inspection and the 
repetitive inspection times into one statement because ADs typically 
call out initial inspections and repetitive inspections in separate 
sentences. Paragraph (h) of this AD specifies only an initial 
inspection. Paragraphs (g), (j), and (k) of this AD specifies an 
initial inspection and states that the repetitive inspections are for 
the unrepaired areas, which are to be done at the applicable times 
specified in Boeing Alert Service Bulletin 747-53A2367, Revision 5, 
dated July 8, 2014. We have not changed this AD in this regard.

Request To Delete the Unrepaired Area Statement From Paragraphs (g) (j) 
and (k) of the Proposed AD (80 FR 25630, May 5, 2015)

    Boeing requested that we delete the last sentence in paragraphs 
(g), (j), and (k) of the proposed AD (80 FR 25630, May 5, 2015), which 
states ``In unrepaired areas, repeat the . . . inspections for cracks . 
. . .'' Boeing stated that the sentence is confusing as the unrepaired 
area case is actually for no cracks found in the modification area 
after doing the inspection as specified in the applicable tables 3, 5, 
and 6 of Boeing Alert Service Bulletin 747-53A2367, Revision 5, dated 
July 8, 2014. Boeing explained that the proposed AD wording may cause 
confusion when information is provided in a different format than the 
service bulletin tables.
    We do not agree with the commenter's request because the text ``in 
unrepaired areas'' matches the text in Boeing Alert Service Bulletin 
747-53A2367, Revision 5, dated July 8, 2014. Paragraphs (g), (j), and 
(k) of this AD specify doing actions at the applicable time specified 
in tables 3, 5, and 6 of paragraph 1.E., ``Compliance,'' of Boeing 
Alert Service Bulletin 747-53A2367, Revision 5, dated July 8, 2014. In 
these tables, the compliance time is specified for the actions required 
for the unrepaired area. We have not revised this AD in this regard.

Request To Combine Paragraphs

    Boeing requested that we combine paragraphs (h) and (i) of the 
proposed AD (80 FR 25630, May 5, 2015) by deleting paragraph (i) of the 
proposed AD and revising paragraph (h) of the proposed AD from ``at the 
applicable time'' to ``at the applicable time and repeat intervals.'' 
Boeing explained that it is confusing to have separate paragraphs 
address initial and repetitive inspections for a particular aircraft as 
both initial and repetitive inspections are addressed within table 4 of 
Boeing Alert Service Bulletin 747-53A2367, Revision 5, dated July 8, 
2014.
    We acknowledge that table 4 of Boeing Alert Service Bulletin 747-
53A2367, Revision 5, dated July 8, 2014, contains compliance times for 
both initial and repetitive inspections. However, we do not agree with 
the commenter's request because the AD includes separate paragraphs in 
order to clarify the repetitive inspection intervals. For the initial 
inspections, table 4 of paragraph 1.E., ``Compliance,'' of Boeing Alert 
Service Bulletin 747-53A2367, Revision 5, dated July 8, 2014, specifies 
two crack conditions, which are based on the number of fight cycles on 
the airplane since stringer 6 external doublers were installed. To aid 
the operators in determining which repetitive inspection(s) they are 
required to do, this AD provides the repetitive inspections (as 
restated from the NPRM (80 FR 25630, May 5, 2015)), depending on the 
applicable condition, in separate repetitive inspection paragraphs 
(paragraphs (i)(1) and (i)(2) of this AD). We have not changed this AD 
in this regard.

Request To Revise External Inspection Wording

    Boeing requested that we remove the word ``external'' from 
paragraph (h) of the proposed AD (80 FR 25630, May 5, 2015), which 
specified ``external detailed, low frequency eddy current, and high 
frequency eddy current inspections.'' Boeing explained that if 
paragraphs (h) and (i) of the proposed AD are combined, both external 
and internal detailed inspections are required. Boeing stated that 
removing ``external'' from the inspection direction would therefore 
cover all airplane conditions.
    As stated previously, we do not agree to combine paragraphs (h) and 
(i) of this AD into one paragraph. Therefore, the terminology in 
paragraph (h) of this AD matches Boeing Alert Service Bulletin 747-
53A2367, Revision 5, dated July 8, 2014, which specifies doing external 
detailed, low frequency eddy current (LFEC), and high frequency eddy 
current (HFEC) inspections for cracks. We have not changed this AD in 
this regard.

Request To Revise Headings of Paragraphs (h), (i), and (j) of the 
Proposed AD (80 FR 25630, May 5, 2015)

    Boeing requested that we revise the headings of paragraphs (h), 
(i), and (j) of the proposed AD (80 FR 25630, May 5, 2015) by adding a 
reference to the applicable service information. Boeing stated that 
these changes will add consistency among paragraphs (h), (i), and (j) 
of the proposed AD in identifying an installed external doubler 
modification.
    We agree with the commenter's request. We have revised the headings 
of paragraphs (h), (i), and (j) of this AD accordingly.

Request To Correct Typographical Error

    Boeing noted that a phrase describing the major action in paragraph 
(j) of the proposed AD (80 FR 25630, May 5, 2015) was duplicated and 
asked that we correct this.
    We agree with the commenter's request. We have revised paragraph 
(j) of this AD accordingly.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this 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 (80 FR 25630, May 5, 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 25630, May 5, 2015).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 747-53A2367, Revision 5,

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.
