Airworthiness Directives; Beechcraft Corporation (Type 
Certificate Previously Held by Hawker Beechcraft Corporation; Raytheon 
Aircraft Company; Beech Aircraft Corporation) 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 Beechcraft Corporation (Type Certificate Previously Held by 
Hawker Beechcraft Corporation; Raytheon Aircraft Company; Beech 
Aircraft Corporation) Model 400, 400A, 400T, and MU-300 airplanes. This 
proposed AD was prompted by a report of a failure of the Acme nut 
threads in a pitch trim actuator (PTA). This proposed AD would require 
an inspection to determine if PTAs having a certain serial number and 
part number are installed, and replacement if they are installed. This 
proposed AD would also require repetitive replacements of PTAs with new 
PTAs or certain overhauled PTAs. We are proposing this AD to prevent 
failure of the Acme nut threads in the PTA, which could lead to loss of 
control of pitch trim and reduced controllability of the airplane.

DATES: We must receive comments on this proposed AD by August 29, 2014.

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: 

Comments Invited

    We invite you to send any written relevant data, views, or 
arguments about this proposal. Send your comments to an address listed 
under the ADDRESSES section. Include ``Docket No. FAA-2014-0345; 
Directorate Identifier 2013-NM-230-AD'' at the beginning of your 
comments. We specifically invite comments on the overall regulatory, 
economic, environmental, and energy aspects of this proposed AD. We 
will consider all comments received by the closing date and may amend 
this proposed 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 proposed AD.

Discussion

    We have received a report of a failure of the Acme nut threads in a 
PTA, due to accelerated thread wear on the Acme nut that mates with the 
jackscrew. This condition, if not corrected, could result in failure of 
the Acme nut threads in the PTA, which could lead to loss of control of 
pitch trim and reduced controllability of the airplane.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin 27-4100, 
dated March 2012. This service bulletin describes procedures for an 
inspection to determine if PTAs having a certain serial number and part 
number are installed, and replacing those PTAs having specific serial 
numbers listed in the service bulletin.

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 these same type 
designs.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously, except as discussed 
under ``Differences Between This Proposed AD and the Service 
Information.''

Differences Between This Proposed AD and the Service Information

    Although Hawker Beechcraft Mandatory Service Bulletin 27-4100, 
dated March 2012, does not require repetitive replacements, this 
proposed AD would require repetitive replacements of PTAs with new PTAs 
or with overhauled PTAs having an Acme nut and jackscrew replaced with 
a new Acme nut and jackscrew every 1,800 flight hours or at the next 
PTA overhaul, whichever occurs first.
    While the effectivity of Hawker Beechcraft Mandatory Service 
Bulletin 27-4100, dated March 2012, does not include Model MU-300 
airplanes, those airplanes are included in the applicability of this 
proposed AD since the affected PTAs can also be used on these 
airplanes.

Costs of Compliance

    We estimate that this proposed AD affects 735 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    According to the manufacturer, the costs of this proposed AD 
associated with Hawker Beechcraft Mandatory Service Bulletin 27-4100, 
dated March 2012, may be covered under warranty, thereby reducing the 
cost impact on affected owners/operators. We do not control warranty 
coverage for affected individuals. As a result, we have included all 
costs in our cost estimate. The costs of the repetitive replacement are 
not covered under warranty. However, the PTA manufacturer states that 
it is already replacing the Acme nut and jackscrew at every overhaul, 
so the owners/operators should not see a cost increase due to this 
repetitive replacement requirement.

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 proposed 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.
