14 CFR Part 39

[Docket No. FAA-2016-0460; Directorate Identifier 2015-NM-078-AD]
RIN 2120-AA64


Airworthiness Directives; Beechcraft Corporation (Type 
Certificate Previously Held by Hawker Beechcraft Corporation; Raytheon 
Aircraft Company) 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 Model BAe.125 series 1000A and 1000B 
airplanes and Model Hawker 1000 airplanes. This proposed AD was 
prompted by reports of inadvertent stowage of the thrust reversers, 
which can result in high forward engine thrust even though the throttle 
is commanding reverse thrust. This proposed AD would require installing 
kits that include relays, associated wiring, and a thrust reverser fail 
annunciator. We are proposing this AD to prevent inadvertent stowage of 
the thrust reversers, which could cause a runway overrun during a 
rejected takeoff or landing, and consequent structural failure and 
possible injury to occupants.

DATES: We must receive comments on this proposed AD by March 7, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

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-2016-0460; 
Directorate Identifier 2015-NM-078-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 reports of inadvertent stowage of the thrust 
reversers, which can result in high forward engine thrust even though 
the throttle is commanding reverse thrust. These reports were on 
another type of airplane that utilizes a similar engine and thrust 
reverser system. The root cause is incorrect software logic within the 
engine's electronic control unit. This condition, if not corrected, 
could result in inadvertent stowage of the thrust reversers, which 
could cause a runway overrun during a rejected takeoff or during 
landing, and consequent structural failure and possible injury to 
occupants.

Related Service Information Under 1 CFR Part 51

    We reviewed Beechcraft Mandatory Service Bulletin 78-4133, dated 
May 2015. The service information describes procedures for installing 
kits having part numbers 140-9005 and 140-9006, which include relays, 
associated wiring, and a thrust reverser fail annunciator. 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

    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, except as discussed 
under ``Differences Between this Proposed AD and the Service 
Information.''

Differences Between This Proposed AD and the Service Information

    Although Beechcraft Mandatory Service Bulletin 78-4133, dated May 
2015, specifies that ``Should any difficulty be encountered in 
accomplishing this Service Bulletin, contact Beechcraft Corporation,'' 
this proposed AD would require operators to resolve difficulties in 
accordance with a method approved by the FAA.

Costs of Compliance

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

                                                 Estimated Costs

                                       per hour = $28,900.
----------------------------------------------------------------------------------------------------------------

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

[[Page 3350]]

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.
