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 BD-100-1A10 airplanes. The NPRM published in the Federal Register 
on January 17, 2018 (83 FR 2373) (``the NPRM''). The NPRM was prompted 
by a report indicating that certain lanyards for the passenger oxygen 
masks located in the airplane's entry area are too long. The NPRM 
proposed to require replacement of certain oxygen mask lanyards with 
shorter lanyards. We are issuing this AD to detect and correct lanyards 
that are too long, which might result in difficulties starting the flow 
of oxygen in an emergency.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2017-22, dated June 23, 
2017 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc., Model BD-100-1A10 airplanes. The MCAI states:

    Bombardier, Inc., has discovered that the entry area passenger 
oxygen mask lanyards are too long. Upon deployment during an 
emergency, this may result in difficulties to start the oxygen flow 
for tall individuals. This [Canadian] AD mandates the replacement of 
the existing entry area passenger oxygen mask lanyards with shorter 
ones for proper operation.

You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
1247.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request To Match Compliance Time in the Service Information

    Bombardier noted that the compliance time in paragraph (g) of the 
proposed AD was ``Within 36 months after the effective date of this 
AD,'' whereas Bombardier Service Bulletin 100-35-08, dated April 11, 
2017, includes a compliance time of within ``36 months from this 
Service Bulletin release date (Basic Issue)''. We infer that the 
commenter is requesting that the compliance time in paragraph (g) of 
the proposed AD be changed to match what is in the service information.
    We do not agree with the commenter's request. In developing an 
appropriate compliance time for this AD, we considered the degree of 
urgency associated with addressing the unsafe condition and the 
manufacturer's recommendation for an appropriate compliance time, as 
well as the time required for the rulemaking process. In consideration 
of these factors, we find that the compliance time, as proposed, 
represents an appropriate interval in which to replace the affected 
oxygen mask lanyards, while still maintaining an adequate level of 
safety. Operators are always permitted to accomplish the requirements 
of an AD at a time earlier than the specified compliance time. We have 
not changed this AD regarding this issue.

Request To Correct Typographical Error

    Bombardier requested that a part number in paragraph (g) of the 
proposed AD be corrected. Paragraph (g) of the proposed AD specified 
the replacement of lanyards having a certain part number with new 
lanyards having part number P/N 289-65-10. The correct part number for 
the new lanyards is P/N 289-165-10.
    We agree with the commenter's request and have revised paragraph 
(g) of this AD to include the correct part number for the new lanyards, 
P/N 289-165-10, which is specified in Bombardier Service Bulletin 100-
35-08, dated April 11, 2017.

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 for correcting the unsafe condition; and

[[Page 28537]]

     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    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

    Bombardier has issued Service Bulletin 100-35-08, dated April 11, 
2017. This service information describes procedures for replacing the 
lanyards in the passenger oxygen masks located in the passenger entry 
area. 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

    We estimate that this AD affects 187 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................           (\1\)              $85          $15,895
----------------------------------------------------------------------------------------------------------------
\1\ We have received no definitive data that will enable us to provide cost estimates for the required parts.

    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 available 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.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2018-13-04 Bombardier, Inc. Amendment 39-19316; Docket No. FAA-2017-
1247; Product Identifier 2017-NM-085-AD.

(a) Effective Date

    This AD is effective July 25, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc., Model BD-100-1A10 
airplanes, certificated in any category, serial numbers 20003 
through 20424 inclusive and 20426 through 20500 inclusive.

(d) Subject

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

(e) Reason

    This AD was prompted by a report indicating that certain 
lanyards for the passenger oxygen masks located in the airplane's 
entry area are 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 detect and 
correct lanyards that are too long, which might result in 
difficulties starting the flow of oxygen in an emergency.

(f) Compliance

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

(g) Lanyard Replacement

    Within 36 months after the effective date of this AD: For any 
entry area passenger oxygen mask dispensing unit (POMDU) having part 
number (P/N) 833-830-01, replace the lanyards in the POMDU with new 
lanyards having P/N 289-165-10, in accordance with the 
Accomplishment Instructions of Bombardier Service Bulletin 100-35-
08, dated April 11, 2017.
