Airworthiness Directives; Beechcraft Corporation (Type 
Certificate Previously Held by Hawker Beechcraft Corporation; Raytheon 
Aircraft Company) Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Beechcraft Corporation Model BAe.125 Series 1000A and 1000B airplanes 
and Model Hawker 1000 airplanes. This 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 AD requires installing kits that include relays, 
associated wiring, and a thrust reverser fail annunciator. We are 
issuing 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: This AD is effective August 12, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of August 12, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Beechcraft 
Corporation Model BAe.125 series 1000A and 1000B airplanes and Model 
Hawker 1000 airplanes. The NPRM published in the Federal Register on 
January 21, 2016 (81 FR 3348) (``the NPRM''). The NPRM 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. The NPRM proposed to require installing kits 
that include relays, associated wiring, and a thrust reverser fail 
annunciator. We are issuing 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.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Support for the NPRM

    Mr. Kevin Maher expressed support for the NPRM.

Request To Revise NPRM Requirement

    Mr. Kenneth Rittenhouse of Becker Aviation LLC requested that we 
not require installation of the service kits, but leave the 
installation decision up to the individual owner/operator. Mr. 
Rittenhouse stated that the NPRM mentions that there have not been any 
issues reported involving Model BAe.125 airplanes but does mention that 
those airplanes have a similar engine/thrust reverser system to 
airplanes on which the problem was reported. Mr. Rittenhouse explained 
that if you examine the Learjet Model 60 and the Model Hawker 1000 
systems, the Hawker 1000 is much more robust with redundant 
capabilities. Mr. Rittenhouse stated that he does not believe the 
unsafe condition has ever been an issue with the Model Hawker 1000 
airplanes, and that it is extremely unjust to force operators to comply 
with this modification that costs 15 percent of the total value of the 
airplane.
    We do not agree with the commenter's request. We recognize that 
maintaining airplanes in an airworthy condition is vital, but sometimes 
expensive. Installation of the service kit corrects a potential unsafe 
condition that could cause a runway overrun during a rejected takeoff 
or landing, and consequent structural failure and possible injury to 
occupants. The service kit was designed and proposed by the airplane 
original equipment manufacturer as its best correction option. The root 
cause of the unsafe condition is incorrect software logic within the 
engine's electronic control unit. We acknowledge the commenter's 
statement indicating that ``the Hawker 1000 is much more robust with 
redundant capabilities,'' however, the commenter did not submit any 
substantiating data to support that statement. We have determined that 
this unsafe condition exists on the Model Hawker 1000 airplanes as well 
as Beechcraft Corporation Model BAe.125 Series 1000A and 1000B 
airplanes. We might approve requests to revise the applicability of 
this AD if the request includes data that justifies such a revision and 
provides an acceptable level of safety. We have not changed this AD in 
this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed, except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Beechcraft 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.

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:

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

[[Page 44496]]

    (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.
