Amendment 39-19020; Docket No. FAA-2017-0608; Product Identifier 2017-CE-017-AD.

(a) EFFECTIVE DATE

    This AD is effective October 16, 2017.

(b) AFFECTED ADS

    None.

(c) APPLICABILITY

    This AD applies to Textron Aviation Inc. (type certificate  previously
    held by  Beechcraft Corporation)  Model 390 airplanes;  serial numbers
    RB-4 through RB-295; certificated in any category.

(d) SUBJECT

    Joint Aircraft System Component (JASC)/Air Transport Association (ATA)
    of America Code 29, Hydraulic Power.

(e) UNSAFE CONDITION

    This  AD was  prompted by  reports of  hydraulic fluid  loss from  the
    engine  driven  pumps  (EDPs) on  three  different  airplanes. We  are
    issuing  this AD  to prevent  cracking  of  the EDP  that could  cause
    leakage  of  hydraulic  fluid  and possibly  lead  to  loss  of normal
    hydraulic functions, which could  lead to a high-speed  runway overrun
    and/or an in-flight fire.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified,  unless al-
    ready done.

(g) INSPECTION

    Within 100 hours  time-in service (TIS)  after  October 16, 2017  (the
    effective date of this AD),  inspect the airplane to determine  if any
    affected serial number EDP,  part number  (P/N) 66179-01  (Beechcraft/
    Textron P/N 390-389022-0003),  is installed on the airplane  following
    the Accomplishment Instructions in Beechcraft Mandatory Service Bulle-
    tin SB 29-4161, dated November 18, 2016. Use table 1 in Parker Service
    Bulletin 66179-29-486, dated August 4, 2016,  to identify the affected
    serial numbers of EDP, P/N 66179-01 (Beechcraft/Textron P/N 390-389022
    -0003).

(h) REPLACEMENT

    If any affected serial number EDP was found  during the inspection re-
    quired in paragraph (g) of this AD, within 100 hours TIS after October
    16, 2017 (the effective date of this AD), replace any affected  serial
    number  EDP,  P/N 66179-01  (Beechcraft/Textron  P/N 390-389022-0003),
    with a serviceable serial number EDP, P/N 66179-01 (Beechcraft/Textron
    P/N 390-389022-0003) that  is either not  listed in table  1 of Parker
    Service  Bulletin  66179-29-486,  dated  August 4, 2016,  or  has been
    reworked following Parker Service Bulletin 66179-29-486, dated  August
    4, 2016. Use the  Accomplishment Instructions in Beechcraft  Mandatory
    Service  Bulletin  SB 29-4161,  dated  November 18,  2016,  to do  the
    replacement actions.

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 Textron Aviation
Inc. Model 390 airplanes (type certificate previously held by
Beechcraft Corporation). The NPRM published in the Federal Register on
June 20, 2017 (82 FR 28026). The NPRM was prompted by 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. The
NPRM proposed to require an inspection to determine if an affected EDP
is installed with replacement as necessary. We are issuing this AD to
correct the unsafe condition on these products.

Comments

We gave the public the opportunity to participate in developing
this final rule. We received no comments on the NPRM or on the
determination of the cost to the public.

Conclusion

We reviewed the relevant data and determined that air safety and
the public interest require adopting this final rule 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 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.

Costs of Compliance

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

Estimated Costs

Action Labor cost Parts cost Cost per product Cost on U.S. operators
Inspection to determine if affected serial number EDP is installed .5 work-hour x $85 per hour = $42.50 Not applicable $42.50 $7,607.50

We estimate the following costs to do any necessary replacement
that would be required based on the results of the 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

Action Labor cost Parts cost Cost per 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 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to small airplanes and domestic
business jet transport airplanes to the Director of the Policy and
Innovation Division.

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
(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.
