We propose to adopt a new airworthiness directive (AD) for certain Textron Aviation Inc. Model 390 airplanes (type certificate previously held by Beechcraft Corporation). This proposed AD was prompted by reports of hydraulic fluid loss from the engine driven pumps (EDPs) on three different airplanes. This proposed AD would require an inspection to determine if an affected EDP is installed with replacement as necessary. We are proposing this AD to address the unsafe condition on these products.

Airworthiness Directives; Textron Aviation Inc. 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 Textron Aviation Inc. Model 390 airplanes (type certificate

Discussion

    We received reports of hydraulic fluid loss from the engine driven 
pumps (EDPs) on three different Textron Aviation Inc. Model 390 
airplanes. In one incident, the airplane exited the runway at a high 
speed, resulting in extensive damage to the airplane. One manufacturing 
lot of EDPs has excessive pitting in the aluminum port caps that could 
cause multiple-origin fatigue cracking of the port caps. Flammable 
hydraulic fluid could leak into the engine compartment, and the leaking 
could also cause loss of all normal hydraulic functions, including 
normal anti-skid braking, ground spoilers, speedbrakes, and normal 
landing gear extension. This condition, if not corrected, could result 
in loss of normal hydraulic functions, which could lead to a high-speed 
runway overrun and/or an in-flight fire.

Related Service Information Under 1 CFR Part 51

    We reviewed Parker Service Bulletin 66179-29-486, dated August 4, 
2016, which identifies the affected serial number EDPs. We also 
reviewed Beechcraft Mandatory Service Bulletin SB 29-4161, dated 
November 18, 2016, which describes procedures for determining if an 
affected serial number EDP is installed and procedures for replacing 
the EDP if necessary. 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

    The service information specifies a compliance time of 200 hours 
time-in-service (TIS) or 12 months, whichever occurs first. This 
proposed AD would require a compliance of 100 hours TIS to reduce the 
possibility of another incident due to a cracked EDP. We removed the 12 
month calendar time from the compliance time because we

[[Page 28027]]

determined the unsafe condition is related to flight hours of the 
airplane rather than calendar time. The requirements of this proposed 
AD take precedence over the requirements of the service information.

Costs of Compliance

    We estimate that this proposed AD affects 179 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

 installed.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacement 
that would be required based on the results of the proposed inspection. 
We estimate the affected manufacturer lot of EDPs as 28 EDPs. If an 
airplane has two of the affected EDPs installed, both EDPs must be 
replaced. However, no more than a total of 28 EDPs will require 
replacing for the U.S. fleet:

                                               On-Condition Costs

                                                                                                     Cost per
                   Action                                 Labor cost                Parts cost        product

Replacement of the EDP.....................  3 work-hours x $85 per hour = $255.         $17,388         $17,643
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some 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.
