For example, if different yaw angles could result in different airbag performance, then additional analysis or separate tests may be necessary to evaluate performance. 3. Neck Injury Criteria: The seating system must protect the occupant from experiencing serious neck injury. The assessment of neck injury must be conducted with the airbag device activated, unless there is reason to also consider that the neckinjury potential would be higher for impacts below the airbag-device deployment threshold. a. The Nij (calculated in accordance with 49 CFR 571.208) must be below 1.0, where Nij = Fz/Fzc + My/Myc, and Nij critical values are: khammond on DSKJM1Z7X2PROD with RULES i. Fzc = 1530 lb for tension ii. Fzc = 1385 lb for compression iii. Myc = 229 lb-ft in flexion iv. Myc = 100 lb-ft in extension b. In addition, peak Fz must be below 937 lb in tension and 899 lb in compression. c. Rotation of the head about its vertical axis, relative to the torso, is limited to 105 degrees in either direction from forward-facing. d. The neck must not impact any surface that would produce concentrated loading on the neck. 4. Spine and Torso Injury Criteria: a. The lumbar spine tension (Fz) cannot exceed 1200 lb. b. Significant concentrated loading on the occupant’s spine, in the area between the pelvis and shoulders during impact, including rebound, is not acceptable. During this type of contact, the interval for any rearward (X direction) acceleration exceeding 20g must be less than 3 milliseconds as measured by the thoracic instrumentation specified in 49 CFR part 572, subpart E, filtered in accordance with SAE International (SAE) recommended practice J211/1, ‘‘Instrumentation for Impact Test–Part 1–Electronic Instrumentation.’’ c. The occupant must not interact with the armrest or other seat components in any manner significantly different than would be expected for a forward-facing seat installation. 5. Pelvis Criteria: Any part of the load-bearing portion of the bottom of the ATD pelvis must not translate beyond the edges of the seat bottom seat-cushion supporting structure. 6. Femur Criteria: Axial rotation of the upper leg (about the z-axis of the femur per SAE VerDate Sep<11>2014 16:05 Dec 11, 2019 Jkt 250001 Recommended Practice J211/1) must be limited to 35 degrees from the nominal seated position. Evaluation during rebound does not need to be considered. 7. ATD and Test Conditions: Longitudinal tests conducted to measure the injury criteria above must be performed with the FAA Hybrid III ATD, as described in SAE 1999–01– 1609, ‘‘A Lumbar Spine Modification to the Hybrid III ATD for Aircraft Seat Tests.’’ The tests must be conducted with an undeformed floor, at the mostcritical yaw cases for injury, and with all lateral structural supports (e.g. armrests or walls) installed. Note: The applicant must demonstrate that the installation of seats via plinths or pallets meets all applicable requirements. Compliance with the guidance contained in policy memorandum PS–ANM–100–2000– 00123, ‘‘Guidance for Demonstrating Compliance with Seat Dynamic Testing for Plinths and Pallets,’’ dated February 2, 2000, is acceptable to the FAA. Inflatable Airbag Restraint Systems Special Conditions: If inflatable airbag restraint systems are installed, the airbag systems must meet the requirements of Airbus Model A330 special conditions no. 25–395–SC, ‘‘Seats with Inflatable Lapbelts.’’ Issued in Des Moines, Washington, on December 6, 2019.

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–2019– 0584. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain Airbus Canada Limited Partnership Model BD–500–1A10 and BD–500–1A11 airplanes. The NPRM published in the Federal Register on August 5, 2019 (84 FR 37976). The NPRM was prompted by a determination that new or more restrictive airworthiness limitations are necessary. The NPRM proposed to require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. The FAA is issuing this AD to address reduced structural integrity of the airplane or reduced controllability of the airplane. See the MCAI for additional background information. The NPRM referred to Canadian AD CF–2019–14, dated April 5, 2019. Since the FAA issued the NPRM, TCCA has issued Canadian AD CF–2019–14R1, dated September 11, 2019, which has no significant changes that affect this AD. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA has received no comments on the NPRM or on the determination of the cost to the public. khammond on DSKJM1Z7X2PROD with RULES Conclusion The FAA has reviewed the relevant data and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing 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 has issued C Series Airworthiness Limitations, BD500– 3AB48–11400–02, Issue 009.00, dated June 6, 2019. This service information describes airworthiness limitations for fuel tank systems, safe life limits, and certification maintenance requirements. This service information is reasonably available because the interested parties VerDate Sep<11>2014 16:05 Dec 11, 2019 Jkt 250001 have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 13 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: The FAA has determined that revising the existing maintenance or inspection program takes an average of 90 workhours per operator, although the agency recognizes that this number may vary from operator to operator. In the past, the FAA has estimated that this action takes 1 work-hour per airplane. Since operators incorporate maintenance or inspection program changes for their affected fleet(s), the FAA has determined that a per-operator estimate is more accurate than a per-airplane estimate. Therefore, the FAA estimates the total cost per operator to be $7,650 (90 work-hours × $85 per work-hour). 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. The FAA is 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 and associated appliances to the Director of the System Oversight Division. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 67831 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) Will not affect intrastate aviation in Alaska, and (3) 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.

SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2019-14R1, dated 
September 11, 2019 (``AD CF-2019-14R1'') (also referred to as the 
Mandatory Continuing Airworthiness Information, or ``the

[[Page 67831]]

MCAI''), to correct an unsafe condition for certain Airbus Canada 
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. 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-2019-
0584.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Airbus Canada 
Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. The 
NPRM published in the Federal Register on August 5, 2019 (84 FR 37976). 
The NPRM was prompted by a determination that new or more restrictive 
airworthiness limitations are necessary. The NPRM proposed to require 
revising the existing maintenance or inspection program, as applicable, 
to incorporate new or more restrictive airworthiness limitations. The 
FAA is issuing this AD to address reduced structural integrity of the 
airplane or reduced controllability of the airplane. See the MCAI for 
additional background information.
    The NPRM referred to Canadian AD CF-2019-14, dated April 5, 2019. 
Since the FAA issued the NPRM, TCCA has issued Canadian AD CF-2019-
14R1, dated September 11, 2019, which has no significant changes that 
affect this AD.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA has received no comments on the 
NPRM or on the determination of the cost to the public.

Conclusion

    The FAA has reviewed the relevant data and determined that air 
safety and the public interest require adopting this final rule as 
proposed, except for minor editorial changes. The FAA has determined 
that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing 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 has issued C Series Airworthiness Limitations, BD500-
3AB48-11400-02, Issue 009.00, dated June 6, 2019. This service 
information describes airworthiness limitations for fuel tank systems, 
safe life limits, and certification maintenance requirements. 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.

Costs of Compliance

    The FAA estimates that this AD affects 13 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:
    The FAA has determined that revising the existing maintenance or 
inspection program takes an average of 90 work-hours per operator, 
although the agency recognizes that this number may vary from operator 
to operator. In the past, the FAA has estimated that this action takes 
1 work-hour per airplane. Since operators incorporate maintenance or 
inspection program changes for their affected fleet(s), the FAA has 
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the FAA estimates the total cost per 
operator to be $7,650 (90 work-hours x $85 per work-hour).

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.
    The FAA is 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 and 
associated appliances to the Director of the System Oversight Division.

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,

[[Page 67832]]

(d) Subject

    Air Transport Association (ATA) of America Code 05, Time Limits/
Maintenance Checks.

(e) Reason

    This AD was prompted by a determination that new or more 
restrictive airworthiness limitations are necessary. The FAA is 
issuing this AD to prevent reduced structural integrity of the 
airplane or reduced controllability of the airplane.

(f) Compliance

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

(g) Maintenance or Inspection Program Revision

    Within 90 days after the effective date of this AD, revise the 
existing maintenance or inspection program, as applicable, to 
incorporate the information specified in Bombardier C Series 
Airworthiness Limitations, BD500-3AB48-11400-02, Issue 009.00, dated 
June 6, 2019. The initial compliance time for doing the tasks is at 
the time specified in Bombardier C Series Airworthiness Limitations, 
BD500-3AB48-11400-02, Issue 009.00, dated June 6, 2019, or within 90 
days after the effective date of this AD, whichever occurs later.

(h) No Alternative Actions, Intervals, or Critical Design Configuration 
Control Limitations (CDCCLs)

    After the existing maintenance or inspection program has been 
revised as required by paragraph (g) of this AD, no alternative 
actions (e.g., inspections), intervals, or CDCCLs may be used unless 
the actions, intervals, and CDCCLs are approved as an alternative 
method of compliance (AMOC) in accordance with the procedures 
specified in paragraph (i)(1) of this AD.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, New 
York ACO Branch, FAA, has the authority to approve AMOCs for this 
AD, if requested using the procedures found in 14 CFR 39.19. In

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.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, New York ACO
