This AD was prompted by a report of a main landing gear (MLG) parking brake becoming dislodged from its mounting bracket due to an improperly installed quick release pin of the hand pump lever. This AD requires removing the hand pump lever of the parking brake from the right-hand side nacelle. We are issuing this AD to prevent an unsecured lever from migrating from its stowed position, fouling against the MLG, and subsequently puncturing the nacelle structure, which could adversely affect the safe landing of the airplane.

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 DHC–8–400, -401, and -402 airplanes. The NPRM published in the Federal Register on April 1, 2015 (80 FR 17366). The Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2014–18, dated June 19, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model DHC–8–400, –401, and –402 airplanes. The MCAI states: There has been one (1) reported in-service incident where the main landing gear (MLG) parking brake hand pump lever was not properly secured in the right-hand (RH) side nacelle and became dislodged from its mounting bracket. During extension of the MLG, the unsecured lever shifted causing a fouling condition with the nacelle and subsequently puncturing the nacelle structure.

We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (80 FR 17366, April 1, 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 17366, April 1, 2015). comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $20,910, or $255 per product. 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 We determined that this AD will not have federalism implications under Executive Order 13132.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model DHC-8-400, -401, and -402 airplanes. This AD was 
prompted by a report of a main landing gear (MLG) parking brake 
becoming dislodged from its mounting bracket due to an improperly 
installed quick release pin of the hand pump lever. This AD requires 
removing the hand pump lever of the parking brake from the right-hand 
side nacelle. We are issuing this AD to prevent an unsecured lever from 
migrating from its stowed position, fouling against the MLG, and 
subsequently puncturing the nacelle structure, which could adversely 
affect the safe landing of the airplane.

DATES: This AD becomes effective October 7, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 7, 
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 Bombardier, Inc. 
Model DHC-8-400, -401, and -402 airplanes. The NPRM published in the 
Federal Register on April 1, 2015 (80 FR 17366).
    The Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-18, dated June 19, 2014 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model DHC-8-400, -401, 
and -402 airplanes. The MCAI states:

    There has been one (1) reported in-service incident where the 
main landing gear (MLG) parking brake hand pump lever was not 
properly secured in the right-hand (RH) side nacelle and became 
dislodged from its mounting bracket. During extension of the MLG, 
the unsecured lever shifted causing a fouling condition with the 
nacelle and subsequently puncturing the nacelle structure.

[[Page 52938]]

    An investigation revealed that the safety restraint pin used to 
securely stow the lever is susceptible to mishandling. An unsecured 
parking brake hand pump lever could migrate from its stowed position 
and foul against the MLG, adversely affecting the safe landing of 
the aeroplane.
    This [Canadian] AD mandates the removal of the MLG parking brake 
hand pump lever from the RH side nacelle.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-0680-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 17366, April 1, 
2015) 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 (80 FR 17366, April 1, 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 17366, April 1, 2015).

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service bulletins.
     Service Bulletin 84-32-99, Revision A, dated October 2, 
2012. This service information describes procedures for incorporating 
ModSum 4-113723 by re-locating the hand pump lever of the parking brake 
from the right-hand side nacelle to the right-hand side equipment bay.
     Service Bulletin 84-32-118, dated April 8, 2014. This 
service information describes procedures for incorporating Bombardier 
ModSum 4-113803 by removing the hand pump lever of the parking brake 
from the right-hand side nacelle.
    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.

Costs of Compliance

    We estimate that this AD affects 82 airplanes of U.S. registry.
    We also estimate that it will take about 3 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost $0 per product. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $20,910, or $255 per product.

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

    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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

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):

2015-17-03 Bombardier, Inc.: Amendment 39-18236. Docket No. FAA-
2015-0680; Directorate Identifier 2014-NM-165-AD.

(a) Effective Date

    This AD becomes effective October 7, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model DHC-8-400, -401, and -
402 airplanes, certificated in any category, serial numbers (S/N) 
4001 through 4419 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
Gear.

(e) Reason

    This AD was prompted by a report of a main landing gear (MLG) 
parking brake becoming dislodged from its mounting bracket due to an 
improperly installed quick release pin of the hand pump lever. We 
are issuing this AD to prevent an unsecured lever from migrating 
from its stowed position, fouling against the MLG, and subsequently 
puncturing the nacelle structure, which could adversely affect the 
safe landing of the airplane.

(f) Compliance

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

(g) Incorporation of Modification Summary (ModSum) 4-113803

    Within 3,000 flight hours or 18 months after the effective date 
of this AD, whichever occurs first: Incorporate Bombardier ModSum 4-
113803 by removing the hand pump lever of the parking brake from the 
right-hand side nacelle, in accordance with the Accomplishment 
Instructions of

[[Page 52939]]

Bombardier Service Bulletin 84-32-118, dated April 8, 2014.

    Note 1 to paragraph (g) of this AD:  Re-installing the hand pump 
lever of the parking brake to the right-hand side equipment bay 
(Bombardier ModSum 4-113804) may be done at the operator's 
discretion.

(h) Optional Installation

    Incorporation of ModSum 4-113723 by re-locating the hand pump 
lever of the parking brake from the right-hand side nacelle to the 
right-hand side equipment bay, in accordance with the Accomplishment 
Instructions of Bombardier Service Bulletin 84-32-99, Revision A, 
dated October 2, 2012, is acceptable for compliance with the 
modification specified in paragraph (g) of this AD, provided the 
incorporation of ModSum 4-113723 is done within the compliance time 
specified in paragraph (g) of this AD.

(i) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(h) of this AD, if those actions were performed before the effective 
date of this AD using Bombardier Service Bulletin 84-32-99, dated 
January 26, 2012, which is not incorporated by reference in this AD.
