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 inadvertent deployment of a single outboard spoiler during flight. This proposed AD would require replacement of the power control units (PCUs) for the outboard spoilers with upgraded PCUs. We are proposing this AD to prevent leakage of the piston head seal and piston rod seals of the outboard spoiler PCUs, which could result in inadvertent spoiler deployment and reduced controllability of the airplane.

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 inadvertent deployment of a 
single outboard spoiler during flight. This proposed AD would require 
replacement of the power control units (PCUs) for the outboard spoilers 
with upgraded PCUs. We are proposing this AD to prevent leakage of the 
piston head seal and piston rod seals of the outboard spoiler PCUs, 
which could result in inadvertent spoiler deployment and reduced 
controllability of the airplane.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-22, dated July 16, 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:

    Although [Canadian] AD CF-2009-26 [dated May 21, 2009 (http://wwwapps3.tc.gc.ca/Saf-Sec-Sur/2/CAWIS-SWIMN/attachment.asp?aiid=CF-2009-26&revid=0&cntr=CF&file=CFCF-2009-26.pdf&type=PDE), which 
corresponds to FAA AD 2009-25-05, Amendment 39-16124 (74 FR 63574, 
December 4, 2009)] was issued to mandate the upgrade of the spoiler 
lift/dump valve, it did not reduce the rate of inadvertent single 
spoiler deployment occurrences. Further investigation revealed that 
the outboard spoiler PCUs may also be subject to pressure reversals 
at the PCU main control valve seal, resulting in leakage at the 
piston head seal and piston rod seals. If not corrected, this 
condition may result in [inadvertent spoiler deployment and] reduced 
controllability of the aeroplane.
    This [Canadian] AD mandates the replacement of the existing 
outboard spoiler PCUs with the upgraded PCUs with re-designed seals 
for better leakage protection.

    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-2015-
0494.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc. has issued Service Bulletin 84-27-63, dated 
October 17, 2013. The service information describes procedures for 
replacement of the existing outboard spoiler PCUs with upgraded PCUs. 
The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI. This service 
information is reasonably available; see ADDRESSES for ways to access 
this service information.

[[Page 15522]]

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 82 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. Required parts would cost about $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $27,880, or $340 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.
