We are superseding Airworthiness Directive (AD) 2012-08-11 for certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2012-08- 11 required repetitive inspections for defects and damage of the retract port flexible hoses on the main landing gear (MLG) retraction actuators, and replacement if necessary. This AD continues to require the actions in AD 2012-08-11, requires reorientation of the retraction actuator of the MLG, and removes airplanes from the applicability. This AD was prompted by test results that showed that failure of a retract port flexible hose of a MLG retraction actuator could cause excessive hydraulic fluid leakage. We are issuing this AD to address the unsafe condition on these products.

SUMMARY: We are superseding Airworthiness Directive (AD) 2012-08-11 for 
certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2012-08-
11 required repetitive inspections for defects and damage of the 
retract port flexible hoses on the main landing gear (MLG) retraction 
actuators, and replacement if necessary. This AD continues to require 
the actions in AD 2012-08-11, requires reorientation of the retraction 
actuator of the MLG, and removes airplanes from the applicability. This 
AD was prompted by test results that showed that failure of a retract 
port flexible hose of a MLG retraction actuator could cause excessive 
hydraulic fluid leakage. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective April 17, 2017.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2012-08-11, Amendment 39-17028 (77 FR 24351, 
April 24, 2012) (``AD 2012-08-11''). AD 2012-08-11 applied to certain 
Bombardier, Inc. Model DHC-8-400 series airplanes. The NPRM published 
in the Federal Register on August 5, 2016 (81 FR 51821). The NPRM was 
prompted by our determination that the left and right MLG retraction 
actuator ports must be reoriented and the retract port flexible hoses 
replaced with hydraulic tube assemblies to address the identified 
unsafe condition. The NPRM proposed to continue to require the actions 
required by AD 2012-08-11. The NPRM also proposed to require 
reorientation of the retraction actuator of the MLG, which would 
terminate the repetitive inspections, and to remove certain airplanes 
from the applicability. We are issuing this AD to prevent hydraulic 
fluid leakage in the event of a retract port flexible hose failure; 
this condition could lead to an undamped extension of the MLG and could 
result in MLG structural failure, leading to an unsafe, asymmetric 
landing configuration.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2011-14R1, effective 
May 21, 2015 (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. This AD also removes airplanes from the applicability of AD 
2012-08-11. The MCAI states:

    Testing has shown that in the event of a main landing gear (MLG) 
retraction actuator retract port flexible hose failure, in-flight 
vibrations may cause excessive hydraulic fluid leakage. This could 
potentially lead to an undamped extension of the MLG, which may 
result in MLG structural failure, leading to an unsafe asymmetric 
landing configuration.
    The original issue of this [Canadian] AD mandated the [detailed] 
inspection [for defects and damage] of the retract port flexible 
hose and its replacement [installing a new retract port flexible 
hose], when required, to prevent damage to the MLG caused by 
undamped gear extensions.
    Revision 1 of this [Canadian] AD mandates the reorientation of 
the MLG Retraction Actuator to prevent hydraulic fluid leakage in 
the event of a damaged retract port flexible hose.

    Airplanes having serial number 4425 and on were modified in 
production and, therefore, the identified unsafe condition does not 
apply to these airplanes. 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-2016-8183.

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 Refer to Updated Service Information

    Horizon Air requested that the NPRM be revised to refer to 
Bombardier Service Bulletin 84-32-106, Revision B, dated June 18, 2015. 
As a result, Horizon Air stated that Bombardier Service Bulletin 84-32-
106, Revision A, dated April 24, 2015, should be included in paragraph 
(i), ``Credit for Previous Actions,'' of the proposed AD along with 
Bombardier Service Bulletin 84-32-106, dated September 28, 2012.
    We agree to refer to the latest service information. We have 
confirmed that the revised service information does not require any 
work beyond what was published in the NPRM. We have revised this AD to 
refer to Bombardier Service Bulletin 84-32-106, Revision B, dated June 
18, 2015, as the appropriate source of service information for 
completing certain actions (Modification Summary (ModSum) 4-902418) 
required by this AD. We have also revised this AD to provide credit for 
actions done before the effective date of this AD using Bombardier 
Service Bulletin 84-32-106, Revision A, dated April 24, 2015.

Request To Correct MCAI Number

    Contact Air Technik GmbH commented that Canadian AD CF-2011-14R1, 
effective May 21, 2015, is incorrectly referenced in paragraph (k),

[[Page 13387]]

``Related Information,'' of the proposed AD as Canadian AD CF-2011-
24R1, effective May 21, 2015.
    We agree that paragraph (k)(1) of this AD should refer to Canadian 
AD CF-2011-14R1, effective May 21, 2015. We have revised paragraph 
(k)(1) of this AD accordingly.

Conclusion

    We reviewed the available data, including 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 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.

Costs of Compliance

    We estimate that this AD affects 82 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                Cost on U.S.

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

    We estimate the following costs to do any necessary replacements 
that will be required based on the results of the required inspection. 
We have no way of determining the number of aircraft that might need 
this replacement:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                       Cost per

 (retained action from AD
 2012[dash]08[dash]11).
----------------------------------------------------------------------------------------------------------------

    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.

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.

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 removing Airworthiness Directive (AD) 
2012-08-11, Amendment 39-17028 (77 FR 24351, April 24, 2012), and 
adding the following new AD:

2017-05-11 Bombardier, Inc.: Amendment 39-18822; Docket No. FAA-
2016-8183; Directorate Identifier 2015-NM-083-AD.

(a) Effective Date

    This AD is effective April 17, 2017.

(b) Affected ADs

    This AD replaces AD 2012-08-11, Amendment 39-17028 (77 FR 24351, 
April 24, 2012) (``AD 2012-08-11'').

gear.

(e) Reason

    This AD was prompted by test reports that showed that failure of 
a retract port flexible hose of a main landing gear (MLG) retraction 
actuator could cause excessive hydraulic fluid leakage. We are 
issuing this AD to prevent hydraulic fluid leakage in the event of a 
retract port flexible hose failure; this condition could lead to an 
undamped extension of the MLG and could result in MLG structural 
failure, leading to an unsafe asymmetric landing configuration.

(f) Compliance

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

(g) Retained Repetitive Inspections and Follow-on Action, With New 
Reference

    This paragraph restates the requirements of paragraph (g) of AD 
2012-08-11, with new reference to terminating action. Within 600 
flight hours after May 29, 2012 (the effective date of AD 2012-08-
11), do a detailed inspection for defects and damage of the retract 
port flexible hose of the left and right MLG retraction actuators, 
in accordance with the Accomplishment Instructions of Bombardier 
Service Bulletin 84-32-89, dated March 22, 2011. Repeat the 
inspection thereafter at intervals not to exceed 600 flight hours. 
If any defect or damage is found, before further flight, replace the 
retract port flexible hose with a new or serviceable retract port 
flexible hose, in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 84-32-89, dated March 22, 2011. Doing 
the actions required by paragraph (h) of this AD terminates the 
inspections required by this paragraph.

(h) New Requirement of This AD: Reorient MLG Retraction Actuators

    Within 6,000 flight hours or 36 months, whichever occurs first 
after the effective date of this AD: Reorient the MLG retraction 
actuator by incorporating Bombardier Modification Summaries 4-902418 
and 4-902327, in accordance with the Accomplishment Instructions of 
the applicable service information specified in paragraphs (h)(1) 
and (h)(2) of this AD. Accomplishment of the actions required by 
this paragraph terminates the actions required by paragraph (g) of 
this AD.
    (1) Bombardier Service Bulletin 84-32-105, Revision A, dated 
April 24, 2015; and Goodrich Service Bulletin 46550-32-99 R2, dated
