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 all 328 Support Services
GmbH Model 328-100 and -300 airplanes. The NPRM published in the
Federal Register on June 7, 2018 (83 FR 26389). The NPRM was prompted
by reports indicating corrosion on the horizontal stabilizer bearing
supports at the contact surface to the horizontal stabilizer rear spar.
The NPRM proposed to require inspections for corrosion and any other
damage (i.e., cracking and chafing) of the horizontal stabilizer rear
bearing supports, replacement of the affected horizontal stabilizer
rear bearing supports if necessary, and modification of the horizontal
stabilizer rear spar.
We are issuing this AD to address corrosion on the horizontal
stabilizer rear bearing supports and rear spar, which could lead to
failure of the fitting and loss of one load path of the horizontal
stabilizer attachment, and possibly result in reduced controllability
of the airplane.
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2017-0239, dated November 30, 2017 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
``the MCAI''), to correct an unsafe condition for all 328 Support
Services GmbH Model 328-100 and -300 airplanes. The MCAI states:

Occurrences were reported on horizontal stabilizer bearing
supports being found corroded at the contact surface to the
horizontal stabilizer rear spar. The corroded area was at the lower
flange position, which is connected to the stabilizer rear spar and
not visible without detachment of the fitting. Investigation
determined that the corrosion is

[[Page 48525]]

triggered by galvanic effect, due to a direct contact between the
horizontal stabilizer rear spar, made from CFRP (carbon fibre
reinforced plastic), and the aluminium rear attachment fitting.
This condition, if not detected and corrected, could lead to
failure of the fitting and loss of one load path of the horizontal
stabilizer attachment, possibly resulting in reduced control of the
aeroplane.
To address this potential unsafe condition, 328 Support Services
GmbH (328 SSG) issued Service Bulletin (SB) SB-328-55-557 and SB-
328J-55-324 to provide instructions for inspection of the affected
area, replacement of the parts, and modification to improve
corrosion behaviour by incorporating of glass fibre layer.
For the reasons described above, this [EASA] AD requires a one-
time inspection [detailed visual inspection and an eddy current
inspection for chafing and corrosion] of the horizontal stabilizer
rear bearing supports, and, depending on findings, accomplishment of
applicable corrective action(s) [replacement of the affected
horizontal stabilizer rear bearing supports]. This [EASA] AD also
requires a modification of the horizontal stabilizer rear spar,
irrespective of findings.

You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0503.

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.

New Service Information

We received 328 Support Services GmbH Service Bulletin SB-328-55-
557, Revision 2, dated May 24, 2018; and 328 Support Services GmbH
Service Bulletin SB-328J-55-324, Revision 2, dated May 24, 2018. We
referred to 328 Support Services GmbH Service Bulletin SB-328-55-557,
Revision 1, dated February 1, 2018; and 328 Support Services GmbH
Service Bulletin SB-328J-55-324, Revision 1, dated February 1, 2018; as
the appropriate sources of service information for the actions
specified in the proposed AD. Revision 2 of the service information
corrects spelling errors and adds alternative parts. No additional work
is needed if the actions specified in the earlier revisions of the
service information have been done.
We have revised this AD to refer to 328 Support Services GmbH
Service Bulletin SB-328-55-557, Revision 2, dated May 24, 2018; and 328
Support Services GmbH Service Bulletin SB-328J-55-324, Revision 2,
dated May 24, 2018, as the appropriate sources of service information
for accomplishing the required actions. We have also added 328 Support
Services GmbH Service Bulletin SB-328-55-557, Revision 1, dated
February 1, 2018; and 328 Support Services GmbH Service Bulletin SB-
328J-55-324, Revision 1, dated February 1, 2018, to paragraph (j) of
this AD in order to give credit for accomplishing actions specified in
Revision 1 of the service information.

Conclusion

We reviewed the relevant data and determined that air safety and
the public interest require adopting this final rule with the changes
described previously and minor editorial changes. We have determined
that these minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.

Related Service Information Under 1 CFR Part 51

328 Support Services GmbH has issued Service Bulletin SB-328-55-
557, Revision 2, dated May 24, 2018; and Service Bulletin SB-328J-55-
324, Revision 2, dated May 24, 2018. This service information describes
procedures for a detailed visual inspection and an eddy current
inspection for corrosion and any other damage (i.e., cracking and
chafing) of the horizontal stabilizer rear bearing supports,
modification of the horizontal stabilizer rear spar, and replacement of
the affected horizontal stabilizer rear bearing supports if necessary.
These documents are distinct since they apply to different airplane
models. This service information is reasonably available because the

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.

[[Page 48526]]

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 transport category airplanes and
associated appliances to the Director of the System Oversight 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 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.
