SUPPLEMENTARY INFORMATION: mechanism when the mask is pulled to the passenger’s face. In an emergency situation where oxygen is required, it is possible that certain passengers may not receive oxygen supply due to the increased length of the lanyard. BA has issued service bulletin (SB) 605– 35–003 to replace the existing lanyards in the passenger oxygen box assemblies with lanyards of the correct length. Incorporation of this BA SB will restore the proper oxygen flow functionality to the passenger oxygen masks in the event of an emergency. This [Canadian] AD mandates the incorporation of [Bombardier] SB 605–35– 003. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0477. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM or on the determination of the cost to the public. Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Bombardier, Inc., Model CL–600–2B16 (CL–601–3A, CL–601–3R, and CL–604 Variants) airplanes. The NPRM published in the Federal Register on May 22, 2017 (82 FR 23156) (‘‘the NPRM’’). The NPRM was prompted by a report indicating that the lanyard length of the passenger drop down oxygen masks is too long. The NPRM proposed to require replacing the existing oxygen mask lanyards with lanyards of the correct length. We are issuing this AD to prevent improper oxygen flow functionality to the passenger oxygen masks in the event of an emergency. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2016–15, dated May 18, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ’’the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL– 600–2B16 (CL–601–3A, CL–601–3R, and CL–604 Variants) airplanes. The MCAI states: Costs of Compliance Bombardier (BA) has determined that the lanyard length of the passenger drop down oxygen masks is too long and may cause the safety pin tethered to the opposite end of the lanyard to remain engaged in the oxygen flow We estimate that this AD affects 120 airplanes of U.S. registry. We estimate the following costs to comply with this AD: 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 for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. Related Service Information Under 1 CFR Part 51 Bombardier, Inc., has issued Service Bulletin 605–35–003, Revision 02, dated April 18, 2016.

We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. sradovich on DSK3GMQ082PROD with RULES 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. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We determined that 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 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 VerDate Sep<11>2014 16:12 Aug 18, 2017 Jkt 241001 under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

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 Airbus Model A300 series airplanes; and Model A300 B4– 600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes). The NPRM published in the Federal Register on May 31, 2017 (82 FR 24903) (‘‘the NPRM’’). The NPRM was prompted by reports of cracks initiating at the upper radius of frame (FR) 47 and a determination that the current inspection procedure is not reliable in detecting certain cracking of the forward fitting of FR 47. The NPRM proposed to require repetitive inspections to detect cracking of the upper radius of the forward fitting of FR 47, and related investigative actions and corrective actions if necessary. We are issuing this AD to detect and correct fatigue cracking of the FR 47 forward fitting upper radius on the left-hand and righthand sides of the fuselage, which could propagate and result in reduced structural integrity of the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2016–0150, dated July 25, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition on all. The MCAI states: During scheduled maintenance inspections on the fuselage, cracks initiating at the upper radius of frame (FR) 47 have been reported on several aeroplanes. Similar damage was also discovered on the A300 fatigue test fuselage. This condition, if not detected and corrected, could reduce the structural integrity of the fuselage. Prompted by these findings, Airbus issued Service Bulletin (SB) A300–53–0246, SB A300–53–6029 and SB A300–53–9014 to provide inspection instructions and, consequently, DGAC France issued AD F– 2006–016 to require repetitive inspections and corrective action. Since that [French] AD was issued, further investigation led to the conclusion that the current ultrasonic inspection performed in accordance with Airbus SB A300–53–0246 Revision 06, or SB A300–53–6029 Revision 08, or SB A300–53–9014 Revision 01, as applicable, was not reliable to detect deep crack going downward. Consequently, to ensure the crack depth is correctly measured whatever the crack direction, Airbus developed a new nondestructive testing method [eddy current] E:\FR\FM\21AUR1.SGM 21AUR1

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 Bombardier, Inc., 
Model CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) 
airplanes. The NPRM published in the Federal Register on May 22, 2017 
(82 FR 23156) (``the NPRM''). The NPRM was prompted by a report 
indicating that the lanyard length of the passenger drop down oxygen 
masks is too long. The NPRM proposed to require replacing the existing 
oxygen mask lanyards with lanyards of the correct length. We are 
issuing this AD to prevent improper oxygen flow functionality to the 
passenger oxygen masks in the event of an emergency.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-15, dated May 18, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ''the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc., Model CL-600-2B16 (CL-
601-3A, CL-601-3R, and CL-604 Variants) airplanes. The MCAI states:

    Bombardier (BA) has determined that the lanyard length of the 
passenger drop down oxygen masks is too long and may cause the 
safety pin tethered to the opposite end of the lanyard to remain 
engaged in the oxygen flow mechanism when the mask is pulled to the 
passenger's face. In an emergency situation where oxygen is 
required, it is possible that certain passengers may not receive 
oxygen supply due to the increased length of the lanyard.
    BA has issued service bulletin (SB) 605-35-003 to replace the 
existing lanyards in the passenger oxygen box assemblies with 
lanyards of the correct length. Incorporation of this BA SB will 
restore the proper oxygen flow functionality to the passenger oxygen 
masks in the event of an emergency.
    This [Canadian] AD mandates the incorporation of [Bombardier] SB 
605-35-003.

    You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0477.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM 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 for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

    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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

Regulatory Findings

    We determined that 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 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.

through 5985 inclusive, 5987, and 5988.

(d) Subject

    Air Transport Association (ATA) of America Code 35, Oxygen.

(e) Reason

    This AD was prompted by a report indicating that the lanyard 
length of the passenger drop down oxygen masks is too long. The 
length of the oxygen mask lanyard might cause the safety pin 
tethered to the opposite end of the lanyard to remain engaged in the 
oxygen flow mechanism when the mask is pulled to the passenger's 
face. We are issuing this AD to prevent improper oxygen flow 
functionality to the passenger oxygen masks in the event of an 
emergency.

(f) Compliance

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

(g) Replacement of Oxygen Mask Lanyards

    Within 2,400 flight hours or 60 months, whichever occurs first 
after the effective date of this AD, replace the existing lanyards 
in the passenger oxygen box assemblies with lanyards of the correct 
length, in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 605-35-003, Revision 02, dated April 18, 
2016.

(h) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(g) of this AD, if those actions were performed before the effective 
date of this AD using Bombardier Service Bulletin 605-35-003, dated 
January 28, 2016; or Bombardier Service Bulletin 605-35-003, 
Revision 01, dated February 10, 2016.
