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:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> 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
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection to determine if .5 work-hour x $85 Not applicable........... $42.50 $7,607.50

installed.
----------------------------------------------------------------------------------------------------------------
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 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
[[Page 42588]]
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.

Comply with this AD within the compliance times specified,
unless already 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 Bulletin 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 required 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.
