Airworthiness Directives; Quest Aircraft Design, LLC 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 Quest Aircraft Design, LLC Model KODIAK 100 airplanes. This 
proposed AD was prompted by a report of limited control yoke movement 
of the elevator control system due to cushion edging jammed in the 
elevator control anti-rotation guide slot. This proposed AD would 
require repetitively inspecting the elevator control system cushion 
edging for proper condition; replacing the cushion edging; and at a 
specified time terminating the repetitive inspections by installing 
wear pads on the elevator bearing assemblies. We are proposing this AD 
to correct the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by December 21, 
2015.

Discussion

    We received a report that, during a preflight inspection, an 
operator noted limited travel of the control yoke on a Quest Aircraft 
Design, LLC Model KODIAK 100 airplane. Upon further inspection of the 
control yoke system forward of the control yoke, cushion edging was 
found jammed in the elevator control anti-rotation guide slot. The 
jammed edging prevented the control yoke from having full nose up and 
nose down travel. The operator also reported the same problem on a 
different KODIAK 100 airplane in which the cushion edging plastic 
portion separated from the metal track.
    Investigation revealed that over time the cushion edging may become 
worn and degrade. This condition, if not corrected, could result in 
failure of the elevator control system cushion edging, which could 
restrict elevator control yoke movement and cause loss of control.

Relevant Service Information

    We reviewed Quest Aircraft KODIAK Mandatory Service Bulletin SB14-
07, dated August 26, 2014; Quest Aircraft Field Service Instruction, 
Elevator Control System--Cushion Edging Inspection, Report No. FSI-105, 
Revision 00, not dated; Quest Aircraft KODIAK 100 Recommended Service 
Bulletin SB15-01, dated March 26, 2015; and Quest Aircraft Field 
Service Instruction, Yoke Anti-Rotation Guide Wear Pad Upgrade, Report 
No. FSI-108, Revision 00, not dated. The service information describes 
procedures for repetitively inspecting the cushion edging installed on 
the elevator control anti-rotation guide for proper condition,

[[Page 68478]]

wear, and security, and replacing if necessary; and removing the 
cushion edging and installing wear pads on the pilot and co-pilot arms 
of the elevator bearing assemblies as a terminating action to the 
repetitive inspections of the cushion edging. 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 of this NPRM.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 60 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

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

    According to the manufacturer, some of the costs of this proposed 
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.
