Airworthiness Directives; Quest Aircraft Design, LLC Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

[[Page 75443]]

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Quest Aircraft Design, LLC (Quest) Model Kodiak 100 airplanes. This AD 
requires you to inspect the torque of the inertial particle separator 
(IPS) bolts; correct the torque, if necessary; replace the IPS bolts 
with new IPS bolts within a certain time; and install safety wire 
around the new IPS bolts. This AD was prompted by five instances where 
a loose IPS bolt was found on the right-hand side of the engine bypass 
door attachment. This condition, if not corrected, could lead to an 
inoperable bypass door, which could result in engine inlet icing with 
consequent loss of engine power and forced landing. We are issuing this 
AD to correct the unsafe condition on these products.

DATES: This AD is effective December 19, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of December 19, 
2011.
    We must receive comments on this AD January 17, 2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION: 

Discussion

    We received reports of five instances where a loose IPS bolt was 
found on the right-hand side of the engine bypass door attachment on 
Quest Model Kodiak 100 airplanes. This area attaches the bypass door to 
the actuating shaft. In one of the five instances, the bolt was lost. 
Loose or missing IPS bolts could lead to an inoperable bypass door, 
which could result in engine inlet icing with consequent loss of engine 
power and forced landing.

Relevant Service Information

    We reviewed Quest Aircraft Company Mandatory Service Bulletin 
Number SB11-17, Revision: 00, dated November 1, 2011; and Quest 
Aircraft Company Field Service Instruction No. FSI-028, Revision 02, 
(undated). The service information describes procedures for inspecting 
and re-torquing the first IPS bolt, replacing both IPS bolts with new 
bolts, and installing safety wire around the new bolts.

FAA's Determination

    We are issuing 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.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information described previously.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because this 
condition, if not corrected, could result in loss of engine power that 
may lead to a forced landing. Therefore, we find that notice and 
opportunity for prior public comment are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include the docket number FAA-2011-1328 and 
Directorate Identifier 2011-CE-037-AD at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this AD. We will 
consider all comments received by the closing date and may amend this 
AD because of those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 38 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

* Not Applicable.

     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

    This AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.
