Airworthiness Directives; Bombardier, Inc. Airplanes, 63341-63343 [2014-25179]

Download as PDF Federal Register / Vol. 79, No. 205 / Thursday, October 23, 2014 / Proposed Rules Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $2,040, or $340 per product. In addition, we estimate that any necessary follow-on actions would take about 4 work-hours and require parts costing $600, for a cost of $940 per product. We have no way of determining the number of products that may need these actions. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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. mstockstill on DSK4VPTVN1PROD with PROPOSALS Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: (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.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-15, dated June 6, 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 series 
airplanes. The MCAI states:

    Several cases have been reported of hydraulic fluid loss from 
the main landing gear (MLG) alternate extension system reservoir and 
in one case, the reservoir was found empty. The cause was determined 
to be an incorrectly assembled reservoir lid. In the event of a 
failed primary MLG extension system, an alternate MLG extension 
system with an empty reservoir may not be able to fully extend the 
MLG into the down and locked position, resulting in an unsafe 
landing configuration.
    This [Canadian] AD mandates the [general visual] inspection of 
the MLG alternate extension system reservoir lid for correct 
assembly and the required rectification [i.e., corrective action 
which consists of repairing the lid assembly].

    The unsafe landing configuration could result in collapse of both 
MLG during touch down. 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-2014-0754.

Relevant Service Information

    Bombardier has issued Service Bulletin 84-29-34, dated May 9, 2013, 
including Parker Service Bulletin 82910012-29-431, dated October 22, 
2012. The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 173 airplanes of U.S. 
registry.
    We also estimate that it would take about 4 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $58,820, or $340 
per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 2 work-hours and require parts costing $0, for a cost of 
$170 per product. We have no way of determining the number of aircraft 
that might need this action.

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

[[Page 63343]]

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.

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.

2. Amend Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2014-0754; Directorate Identifier 
2014-NM-136-AD.

(a) Comments Due Date

    We must receive comments by December 8, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model DHC-8-401, -402, and -
403 airplanes, certificated in any category, serial numbers 4001 
through 4424 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 29, Hydraulic 
Power.

(e) Reason

    This AD was prompted by reports of hydraulic fluid loss from the 
reservoir of the main landing gear's (MLG's) alternate extension 
system. We are issuing this AD to, in the event of a failure of the 
primary MLG extension system, prevent failure of the alternate MLG 
extension system to fully extend the MLG into a down-and-locked 
position, which could result in collapse of both MLG during 
touchdown.

(f) Compliance

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

(g) Inspection and Corrective Action

    Within 2,000 flight hours or 12 months after the effective date 
of this AD, whichever occurs first: Do a general visual inspection 
of the MLG alternate extension system reservoir lid for correct 
assembly, and do all applicable corrective actions, in accordance 
with the Accomplishment Instructions of Bombardier Service Bulletin 
84-29-34, dated May 9, 2013, including Parker Service Bulletin 
82910012-29-431, dated October 22, 2012. Do all applicable 
corrective actions within 2,000 flight hours or 12 months after the 
effective date of this AD, whichever occurs first.

(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 All Operator Message 543, dated 
October 17, 2012, which is not incorporated by reference in 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 Aircraft Certification Office (ACO), ANE-170, FAA, has the 
authority to approve AMOCs for this AD, if requested using the

Before 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. The AMOC approval letter must specifically reference this 
AD.
    (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, 
ANE-170, Engine and Propeller Directorate, FAA; or Transport Canada
