We propose to supersede Airworthiness Directive (AD) 2016-13- 14, for certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 2016-13-14 requires an inspection to determine if certain left and right main landing gear (MLG) retract actuator rod ends are installed and repetitive liquid penetrant inspections (LPIs) of affected left and right MLG retract actuator rod ends, and corrective actions if necessary. Since we issued AD 2016-13-14, we have determined that replacement of the left and right MLG is necessary to address the unsafe condition. This proposed AD would retain the actions specified in AD 2016-13-14 and add a replacement of the left and right MLG retract actuator rod ends. We are proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Bombardier, Inc., Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2016-13-
14, for certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 
2016-13-14 requires an inspection to determine if certain left and 
right main landing gear (MLG) retract actuator rod ends are installed 
and repetitive liquid penetrant inspections (LPIs) of affected left and 
right MLG retract actuator rod ends, and corrective actions if 
necessary. Since we issued AD 2016-13-14, we have determined that 
replacement of the left and right MLG is necessary to address the 
unsafe condition. This proposed AD would retain the actions specified 
in AD 2016-13-14 and add a replacement of the left and right MLG 
retract actuator rod ends. We are proposing this AD to address the 
unsafe condition on these products.

Discussion

    On June 22, 2016, we issued AD 2016-13-14, Amendment 39-18579 (81 
FR 43481, July 5, 2016) (``AD 2016-13-14''), for certain Bombardier, 
Inc., Model DHC-8-400 series airplanes. AD 2016-13-14 was prompted by a 
report of a cracked MLG retract actuator rod end. AD 2016-13-14 
requires an inspection to determine if certain left and right MLG 
retract actuator rod ends are installed and repetitive LPIs of affected 
left and right MLG retract actuator rod ends, and corrective actions if 
necessary. AD 2016-13-14 also provides optional terminating action for 
the inspections. We issued AD 2016-13-14 to detect and correct fatigue 
cracking of the left and right MLG retract actuator rod ends, which 
could lead to left or right MLG collapse.
    The preamble to AD 2016-13-14 explains that we consider the 
requirements ``interim action'' and were considering further 
rulemaking. We now have determined that further rulemaking is indeed 
necessary, and this proposed AD follows from that determination.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2016-16R1, dated June 
27, 2016 (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:

    There has been a single reported case of a cracked MLG retract 
actuator rod end in service. A supplier disclosure letter and 
subsequent Bombardier analysis indicate that the MLG retract 
actuator rod end P/N [part number] P3A2750 and P3A2750-1 may develop 
fatigue cracking. This condition, if not corrected, could lead to 
left hand (LH) or right hand (RH) MLG collapse.
    This [Canadian] AD mandates the inspection [to determine if 
certain left and right main landing gear MLG retract actuator rod 
ends are installed, repetitive LPIs of affected left and right MLG 
retract actuator rod ends, and corrective actions if necessary], and 
replacement of the LH and RH MLG retract actuator rod ends P/N 
P3A2750 and

[[Page 35128]]

P3A2750-1 [which is terminating action for the repetitive LPIs].
    This [Canadian] AD was revised to clarify paragraph B. and C. 
[of this Canadian AD], which specifies when the Liquid Penetrant 
Inspections (LPI) should begin.

    Corrective actions includes replacing cracked MLG retract actuator 
rod ends. 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-2017-0712.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc. has issued Bombardier Service Bulletin 84-32-142, 
dated May 4, 2016. This service information describes procedures for an 
inspection to determine if certain left and right MLG retract actuator 
rod ends are installed, repetitive LPIs of the left and right MLG 
retract actuator rod ends, and replacement of left and right MLG 
retract actuator rod ends. 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.

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 52 airplanes of U.S. 
registry.
    The actions required by AD 2016-13-14, and retained in this 
proposed AD takes about 1 work-hour per product, at an average labor 
rate of $85 per work-hour. Based on these figures, the estimated cost 
of the inspection that is required by AD 2016-13-14 is $85 per product.
    We also estimate that it would take about 3 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 $2,019 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $118,248, or $2,274 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 3 work-hours and require parts costing $2,019, for a cost of 
$2,274 per product. We have no way of determining the number of 
aircraft that might need these actions.
    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 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.
