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

AGENCY: Federal Aviation Administration (FAA), DOT.

[[Page 22784]]


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) Model Hawker 
800XP, 850XP, and 900XP airplanes. This proposed AD was prompted by a 
design review that revealed there were no instructions to apply sealant 
to structural components in the fuel tank during the winglet 
installation process. This proposed AD would require an inspection for 
the presence of sealant on doubler plate edges, doubler plate rivets, 
and adjacent skin in the fuel vent surge tanks; and corrective actions 
if necessary. We are proposing this AD to detect and correct missing 
sealant, which, during a lightning strike, could result in a potential 
source of ignition in a fuel tank and consequent explosion or fire and 
subsequent in-flight breakup of the airplane.

DATES: We must receive comments on this proposed AD by June 9, 2014.

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

Discussion

    We found during a design review that included the winglet kit that 
there were no instructions to apply sealant to structural components in 
the fuel tank during the winglet installation process. The sealant is 
part of the lightning protection design for the fuel tanks. Missing 
sealant, if not detected and corrected, could result in a potential 
source of ignition in a fuel tank during a lightning strike and 
consequent explosion or fire and subsequent in-flight breakup of the 
airplane.

Relevant Service Information

    We reviewed Hawker Beechcraft Mandatory Service Bulletin SB 57-
4112, dated February 2013. The service information describes procedures 
for inspecting for the presence of sealant on doubler plate edges, 
doubler plate rivets, and adjacent skin in the top and bottom of the 
left and right fuel vent surge tanks; and applying sealant if 
necessary.

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 the Proposed AD and the Service 
Information.''

Differences Between This Proposed AD and the Service Information

    The service information identifies Model 800XP and 850XP airplanes 
equipped with certain kits, but does not specify the serial numbers of 
Model 800XP and 850XP airplanes that are eligible to have those kits 
installed. We have listed those serial numbers in paragraph (g) of this 
proposed AD.
    The service information refers only to an ``inspection'' to 
determine the presence of sealant. We have determined that the 
inspection should be described as a ``general visual inspection.'' We 
have defined this type of inspection in paragraph (h) of this proposed 
AD.
    The service information includes a note in the Accomplishment 
Instructions to inform operators to contact Hawker Beechcraft ``should 
any difficulty be encountered'' in accomplishing the service 
information. We have clarified in paragraph (i) of this proposed AD 
that any deviation from the instructions provided in the service 
information must be approved as an alternative method of compliance 
under the provisions of paragraph (k) of this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 50 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

[[Page 22785]]



                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
              Action                      Labor cost             Parts cost           Product        operators
----------------------------------------------------------------------------------------------------------------
Inspection........................  2 work-hours x $85     None.................            $170          $8,500
                                     per hour = $170.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the proposed inspection. We 
have no way of determining the number of aircraft that might need these 
repairs:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                   Action                                Labor cost                Parts cost        product
----------------------------------------------------------------------------------------------------------------
Sealant application.........................  36 work-hours x $85 per hour =               $32           $3,092
                                               $3,060.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all 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.

(h) Definition

    For the purposes of this AD, a general visual inspection is a 
visual examination of an interior or exterior area, installation, or 
assembly to detect obvious damage, failure, or irregularity. This 
level of inspection is made from within touching distance unless 
otherwise specified. A mirror may be necessary to ensure visual 
access to all surfaces in the inspection area. This level of 
inspection is made under normally available lighting conditions such 
as daylight, hangar lighting, flashlight, or droplight and may 
require removal or opening of access panels or doors. Stands, 
ladders, or platforms may be required to gain proximity to the area 
being checked.

(i) Exception to the Service Information

    A note in the Accomplishment Instructions of the Hawker 
Beechcraft Mandatory Service Bulletin SB 57-4112, dated February 
2013, instructs operators to contact Hawker Beechcraft if any 
difficulty is encountered in accomplishing the service information. 
However, this AD requires that any deviation from the instructions 
provided in Hawker Beechcraft Mandatory Service Bulletin SB 57-4112, 
dated February 2013, must be approved as an alternative method of 
compliance (AMOC) under the provisions of paragraph (k) of this AD.

(j) Parts Installation Limitation

    For all airplanes: As of the effective date of this AD, no kit 
having kit number 140-1701-1, 140-1702-1, 140-1703-1, 140-1703-5, 
140-1703-7, or 140-1704-1 that was purchased before February 13, 
2013, may be installed on any airplane unless the installation 
includes sealant on doubler plate edges, doubler plate rivets, and 
adjacent skin in the top and bottom of the left and right fuel vent 
surge tanks, as specified in the Accomplishment Instructions of 
Hawker Beechcraft Mandatory Service Bulletin SB 57-4112, dated 
February 2013.
