Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model DHC-8-400 series airplanes. This 
proposed AD was prompted by reports of chafing of the fuel lines due to 
contact with the surrounding structures in the fuel tank. This proposed 
AD would require replacing and modifying fuel lines, revising the 
maintenance or inspection program, as applicable, to include critical 
design configuration control limitations (CDCCL) and airworthiness 
limitation (AWL) items, and, for certain airplanes removing certain 
clamps and mounting hardware. We are proposing this AD to prevent 
chafing of the fuel lines in the fuel tank, which could result in 
potential ignition sources in the fuel tank in the event of a lightning 
strike and consequent fire or explosion.

DATES: We must receive comments on this proposed AD by October 10, 
2014.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-09R1, dated May 28, 2013 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

    Reports from operators have revealed a number of instances of 
chafing of the fuel lines due to contact with the surrounding 
structures in the fuel tank. An internal audit conducted by 
Bombardier revealed a number of locations in the fuel tank where low 
clearances were noted between fuel lines and the surrounding 
structure. Low clearances between fuel lines and the surrounding 
structures may result in ignition sources in the fuel tank in the 
event of a lightning strike, creating an unacceptable level of 
safety.
    Bombardier had issued Service Bulletin (SB) 84-28-09 to 
introduce new fuel line assemblies that include new fuel lines and 
Teflon protective sleeves, and SBs 84-28-10 and 84-28-13 to remove 
unnecessary hardware in the wing fuel tanks, in order to eliminate 
potential fouling conditions on the affected fuel lines.
    Upon an operator's incorporation of SB 84-28-09, an additional 
fouling condition was identified on the post-modification fuel 
lines. In order to address this concern on the aeroplane, Bombardier 
has issued SBs 84-28-14 and 84-28-15, along with ModSum IS4Q2800012 
to rectify this problem.
    This [Canadian] AD mandates the replacement of fuel lines and 
the installation of fuel line Teflon protective sleeves. In 
addition, the fuel line Teflon protective sleeves have been added to 
the Critical Design Configuration Control Limitations (CDCCL) along 
with the introduction of associated Fuel System Limitations tasks, 
to ensure integrity of the new assembly.
    Since the original issue of this [Canadian] AD, it was found 
that there were editorial errors in Parts IB and II A of this 
[Canadian] AD. In addition, the Temporary Revisions (TR) 
Airworthiness Limitation Items (ALI)-111/-112 referenced in Parts 
III and IV of this AD had been superseded by later revisions. This 
[Canadian] AD is revised to correct the editorial errors and accept 
the later TR approved by Transport Canada.

    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-
0583.

Relevant Service Information

    Bombardier has issued the following service information:

Limitation Items,'' of the Airworthiness Limitation Items section of 
Bombardier Q400 Dash 8 Maintenance Requirements Manual PSM 1-84-7; and
     Temporary Revision ALI-112, dated January 11, 2011, to 
Section 5-1,

[[Page 50861]]

``Critical Design Configuration Control Limitations,'' of Part 2, 
``Airworthiness Limitation Items,'' of the Airworthiness Limitation 
Items section of Bombardier Q400 Dash 8 Maintenance Requirements Manual 
PSM 1-84-7.
    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.

Compliance With the Required Actions and Sections of Maintenance 
Documents

    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
Critical Design Configuration Control Limitations (CDCCLs). Compliance 
with these actions and CDCCLs is required by section 91.403(c) of the 
Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that 
have been previously modified, altered, or repaired in the areas 
addressed by these inspections, an operator might not be able to 
accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval of an alternative method of compliance (AMOC) in accordance 
with the provisions of paragraph (o)(1) of this proposed AD. The 
request should include a description of changes to the required 
inspections that will ensure the continued operational safety of the 
airplane.

``Contacting the Manufacturer'' Paragraph in This Proposed AD

    Since late 2006, we have included a standard paragraph titled 
``Airworthy Product'' in all MCAI ADs in which the FAA develops an AD 
based on a foreign authority's AD.
    The MCAI or referenced service information in an FAA AD often 
directs the owner/operator to contact the manufacturer for corrective 
actions, such as a repair. Briefly, the Airworthy Product paragraph 
allowed owners/operators to use corrective actions provided by the 
manufacturer if those actions were FAA-approved. In addition, the 
paragraph stated that any actions approved by the State of Design 
Authority (or its delegated agent) are considered to be FAA-approved.
    In an NPRM having Directorate Identifier 2012-NM-101-AD (78 FR 
78285, December 26, 2013), we proposed to prevent the use of repairs 
that were not specifically developed to correct the unsafe condition, 
by requiring that the repair approval provided by the State of Design 
Authority or its delegated agent specifically refer to the FAA AD. This 
change was intended to clarify the method of compliance and to provide 
operators with better visibility of repairs that are specifically 
developed and approved to correct the unsafe condition. In addition, we 
proposed to change the phrase ``its delegated agent'' to include a 
design approval holder (DAH) with State of Design Authority design 
organization approval (DOA), as applicable, to refer to a DAH 
authorized to approve required repairs for the proposed AD.
    One commenter to the NPRM having Directorate Identifier 2012-NM-
101-AD (78 FR 78285, December 26, 2013) stated the following: ``The 
proposed wording, being specific to repairs, eliminates the 
interpretation that Airbus messages are acceptable for approving minor 
deviations (corrective actions) needed during accomplishment of an AD 
mandated Airbus service bulletin.''
    This comment has made the FAA aware that some operators have 
misunderstood or misinterpreted the Airworthy Product paragraph to 
allow the owner/operator to use messages provided by the manufacturer 
as approval of deviations during the accomplishment of an AD-mandated 
action. The Airworthy Product paragraph does not approve messages or 
other information provided by the manufacturer for deviations to the 
requirements of the AD-mandated actions. The Airworthy Product 
paragraph only addresses the requirement to contact the manufacturer 
for corrective actions for the identified unsafe condition and does not 
cover deviations from other AD requirements. However, deviations to AD-
required actions are addressed in 14 CFR 39.17, and anyone may request 
the approval for an alternative method of compliance to the AD-required 
actions using the procedures found in 14 CFR 39.19.
    To address this misunderstanding and misinterpretation of the 
Airworthy Product paragraph, we have changed the paragraph and retitled 
it ``Contacting the Manufacturer.'' This paragraph now clarifies that 
for any requirement in this proposed AD to obtain corrective actions 
from a manufacturer, the actions must be accomplished using a method 
approved by the FAA, TCCA, or Bombardier, Inc.'s TCCA Design Approval 
Organization (DAO).
    The Contacting the Manufacturer paragraph also clarifies that, if 
approved by the DAO, the approval must include the DAO-authorized 
signature. The DAO signature indicates that the data and information 
contained in the document are TCCA-approved, which is also FAA-
approved. Messages and other information provided by the manufacturer 
that do not contain the DAO-authorized signature approval are not TCCA-
approved, unless TCCA directly approves the manufacturer's message or 
other information.
    This clarification does not remove flexibility previously afforded 
by the Airworthy Product paragraph. Consistent with long-standing FAA 
policy, such flexibility was never intended for required actions. This 
is also consistent with the recommendation of the Airworthiness 
Directive Implementation Aviation Rulemaking Committee to increase 
flexibility in complying with ADs by identifying those actions in 
manufacturers' service instructions that are ``Required for 
Compliance'' with ADs. We continue to work with manufacturers to 
implement this recommendation. But once we determine that an action is 
required, any deviation from the requirement must be approved as an 
alternative method of compliance.
    We also have decided not to include a generic reference to either 
the ``delegated agent'' or ``design approval holder (DAH) with State of 
Design Authority design organization approval,'' but instead we have 
provided the specific delegation approval granted by the State of 
Design Authority for the DAH throughout this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 72 airplanes of U.S. 
registry.
    We also estimate that it would take about 80 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost up to $2,845 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be up to $694,440, or $9,645 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 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.
