SUPPLEMENTARY INFORMATION: Discussion The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2019–0096, dated April 30, 2019 (‘‘EASA AD 2019–0096’’) (also referred to as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain 328 Support Services GmbH Model 328–100 airplanes. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain 328 Support Services GmbH Model 328–100 airplanes. The NPRM published in the Federal Register on September 9, 2019 (84 FR 47173). The NPRM was prompted by a report of missing rivets on landing flap support arm 2. The NPRM proposed to require an inspection of the landing flap support arms for missing rivets and corrective actions if necessary. The FAA is issuing this AD to address missing rivets, which could lead to the loss of one of two load paths, reducing the fatigue life of the affected flap arms and leading to fatigue cracking of the support arms of the flaps, which could result in reduced structural integrity of the airplane. See the MCAI for additional background information. Comments The FAA gave the public the opportunity to participate in developing this final rule. The agency received no comments on the NPRM or on the determination of the cost to the public. Conclusion The FAA 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. The FAA has 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. Related IBR Material Under 1 CFR Part 51 EASA AD 2019–0096 describes procedures for an inspection of the landing flap support arms for missing rivets, which includes a special detailed inspection (eddy current) of the landing flap support 2 arm along the edges and around the rivets for cracks, and corrective actions. Corrective actions include installing rivets and repairing cracks. This material 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 The FAA estimates that this AD affects 22 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 6 work-hours × $85 per hour = $510 .......................................................................................... $0 $510 $11,220 khammond on DSKJM1Z7X2PROD with RULES The FAA estimates the following costs to do any necessary on-condition installation that would be required based on the results of any required actions. The FAA has no way of determining the number of aircraft that might need this on-condition installation: ESTIMATED COSTS OF ON-CONDITION INSTALLATION Labor cost Parts cost Cost per product 4 work-hours × $85 per hour = $340 ...................................................................................................................... $27 $367 VerDate Sep<11>2014 16:33 Dec 27, 2019 Jkt 250001 PO 00000 Frm 00049 Fmt 4700 Sfmt 4700 E:\FR\FM\30DER1.SGM 30DER1 71784 Federal Register / Vol. 84, No. 249 / Monday, December 30, 2019 / Rules and Regulations The FAA has received no definitive data that would enable the FAA to provide cost estimates for the oncondition crack repairs specified in this AD. 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. The FAA is 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. khammond on DSKJM1Z7X2PROD with RULES 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) Will not affect intrastate aviation in Alaska, and (3) 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.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0096, dated April 30, 2019 
(``EASA AD 2019-0096'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain 328 Support Services GmbH Model 328-100 
airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain 328 Support 
Services GmbH Model 328-100 airplanes. The NPRM published in the 
Federal Register on September 9, 2019 (84 FR 47173). The NPRM was 
prompted by a report of missing rivets on landing flap support arm 2. 
The NPRM proposed to require an inspection of the landing flap support 
arms for missing rivets and corrective actions if necessary.
    The FAA is issuing this AD to address missing rivets, which could 
lead to the loss of one of two load paths, reducing the fatigue life of 
the affected flap arms and leading to fatigue cracking of the support 
arms of the flaps, which could result in reduced structural integrity 
of the airplane. See the MCAI for additional background information.

Comments

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

Conclusion

    The FAA 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. The FAA has 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.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0096 describes procedures for an inspection of the 
landing flap support arms for missing rivets, which includes a special 
detailed inspection (eddy current) of the landing flap support 2 arm 
along the edges and around the rivets for cracks, and corrective 
actions. Corrective actions include installing rivets and repairing 
cracks. This material 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

    The FAA estimates that this AD affects 22 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
6 work-hours x $85 per hour = $510...........................              $0             $510          $11,220
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition installation that would be required based on the results of 
any required actions. The FAA has no way of determining the number of 
aircraft that might need this on-condition installation:

              Estimated Costs of On-Condition Installation
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
4 work-hours x $85 per hour = $340....             $27             $367
------------------------------------------------------------------------

    The FAA has received no definitive data that would enable the FAA 
to provide cost estimates for the on-condition crack repairs specified 
in this AD.

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.
    The FAA is 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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
