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 E:\FR\FM\26SER1.SGM 26SER1 Federal Register / Vol. 83, No. 187 / Wednesday, September 26, 2018 / Rules and Regulations 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 https:// 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. 48525 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 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 27 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Cost per product Parts cost Cost on U.S. operators Action Labor cost Detailed visual inspection and eddy current inspection.

Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 328 
Support Services GmbH Model 328-100 and -300 airplanes. This AD was 
prompted by reports indicating corrosion on the horizontal stabilizer 
bearing supports at the contact surface to the horizontal stabilizer 
rear spar. This AD requires 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 the unsafe 
condition on these products.

DATES: This AD is effective October 31, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 31, 
2018.

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 https://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.
