Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2017– 0220, dated November 10, 2017 (referred to hereinafter as ‘‘the MCAI’’), to address the unsafe condition on these products. The MCAI states: In 1983, occurrences were reported of fatigue failure of propeller blade lag screws, at rotation speeds between 2950 and 3250 revolutions per minute (RPM) in flight. This condition, if not detected and corrected, could lead to in-flight propeller blade detachment, possibly resulting in damage to the powered sailplane and/or injury to persons on the ground. To address this potential unsafe condition, Hoffmann issued Service Bulletin (SB) 4, providing the necessary instructions. Consequently, LBA Germany issued AD 83– 150 (later revised), which applied only to HO–V 62 propellers with R/L 160T blades, when in combination with a Limbach L 2000 engine, to require a limitation of continuous operation to 2 900 RPM, to prohibit aerobatic flights, calibrate the tachometer, install a PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 32219 placard, and inspection of the propeller blades. LBA AD 83–150/4 also required overhaul and replacement of the affected propeller blades with modified blades, either having 5 lag screws with 12 mm diameter, or 6 screws, and required implementing a time between overhaul (TBO) of 600 flight hours (FH). Since that AD was issued, based on a stress analysis of lag screws on blades with continuous operating speed above 2 900 RPM, it was determined that the 6-screws configuration or the 5 screws configuration with increased strength is necessary to ensure safe propeller operation. In addition, since the LBA AD applied only to a limited population (Limbach engine only), many propellers have not been modified as described in Hoffmann SB 4C. Consequently, Hoffmann issued SB E34 Revision B, to provide blade replacement instructions. You may obtain further information by examining the MCAI in the AD docket on the internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0281. Related Service Information We reviewed Hoffmann Propeller GmbH & Co. KG Service Bulletin (SB) E34, Rev. B, dated September 18, 2017. The SB describes the instructions for the removal and installation of the propeller blades. FAA’s Determination This product has been approved by EASA, and is approved for operation in the United States. Pursuant to our bilateral agreement with the European Community, EASA has notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all the relevant information provided by EASA and determined the unsafe condition previously described is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would require removal of the affected propeller blades and installation of the modified propeller blades marked with change letter ‘‘A’’ or ‘‘B’’ on the blade. Differences Between This Proposed AD and the MCAI or Service Information EASA AD 2017–0220 partially restates the requirements of AD 83–150, issued on December 21, 1984, by German aviation authority LuftfahrtBundesamt (LBA), which is based on Propellerwerk Hoffmann Rosenheim SB 4, Revision C, dated February 20, 1984. EASA AD 2017–0220 also adds new requirements based on the issuance of E:\FR\FM\12JYP1.SGM 12JYP1 32220 Federal Register / Vol. 83, No. 134 / Thursday, July 12, 2018 / Proposed Rules Hoffmann Propeller GmbH & Co. KG SB E34, Rev. B dated September 18, 2017. In restating LBA AD 83–150, EASA AD 2017–0220 maintains a requirement to remove certain propellers from service within 10 flight hours after December 21, 1984, but not later than 31 March 31, 1985. Service Bulletin E34 requires a mandatory immediate maximum propeller rotational speed limitation until the permanent corrective action is completed, within 50 flight hours. The EASA AD 2017– 0220 partially restated requirements of SB 4. Additionally, Hoffmann Propeller GmbH & Co. KG SB E34 Revision B and SB 4 Revision C temporarily prohibit acrobatic flight. EASA AD 2017–0220 also adds a new requirement for a mandatory maximum propeller rotational speed limitation within 30 days until the propeller is replaced within 50 flight hours. This proposed AD does not require a propeller speed limitation but would require removal of the affected propeller blades and installation of modified propeller blades within 30 days of the effective date of this AD. Costs of Compliance We estimate that this proposed AD affects 50 propellers installed on airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Labor cost Replace Blades between overhaul ................. Replace Blades at overhaul ............................ amozie on DSK3GDR082PROD with PROPOSALS1 Action 3.0 work-hours × $85 per hour = $255.00 ..... 0 work-hours × $85 per hour = $0.00 ............ 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 engines, propellers, and associated appliances to the Manager, Engine and Propeller Standards Branch, Policy and Innovation Division. Regulatory Findings We determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national VerDate Sep<11>2014 16:28 Jul 11, 2018 Jkt 244001 Parts cost 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 this proposed regulation: (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.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD 2017-0220, dated November 10, 2017 (referred to hereinafter as ``the 
MCAI''), to address the unsafe condition on these products. The MCAI 
states:

    In 1983, occurrences were reported of fatigue failure of 
propeller blade lag screws, at rotation speeds between 2950 and 3250 
revolutions per minute (RPM) in flight.
    This condition, if not detected and corrected, could lead to in-
flight propeller blade detachment, possibly resulting in damage to 
the powered sailplane and/or injury to persons on the ground.
    To address this potential unsafe condition, Hoffmann issued 
Service Bulletin (SB) 4, providing the necessary instructions. 
Consequently, LBA Germany issued AD 83-150 (later revised), which 
applied only to HO-V 62 propellers with R/L 160T blades, when in 
combination with a Limbach L 2000 engine, to require a limitation of 
continuous operation to 2 900 RPM, to prohibit aerobatic flights, 
calibrate the tachometer, install a placard, and inspection of the 
propeller blades. LBA AD 83-150/4 also required overhaul and 
replacement of the affected propeller blades with modified blades, 
either having 5 lag screws with 12 mm diameter, or 6 screws, and 
required implementing a time between overhaul (TBO) of 600 flight 
hours (FH).
    Since that AD was issued, based on a stress analysis of lag 
screws on blades with continuous operating speed above 2 900 RPM, it 
was determined that the 6-screws configuration or the 5 screws 
configuration with increased strength is necessary to ensure safe 
propeller operation. In addition, since the LBA AD applied only to a 
limited population (Limbach engine only), many propellers have not 
been modified as described in Hoffmann SB 4C. Consequently, Hoffmann 
issued SB E34 Revision B, to provide blade replacement instructions.

    You may obtain further information by examining the MCAI in the AD 
docket on the internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2018-0281.

Related Service Information

    We reviewed Hoffmann Propeller GmbH & Co. KG Service Bulletin (SB) 
E34, Rev. B, dated September 18, 2017. The SB describes the 
instructions for the removal and installation of the propeller blades.

FAA's Determination

    This product has been approved by EASA, and is approved for 
operation in the United States. Pursuant to our bilateral agreement 
with the European Community, EASA has notified us of the unsafe 
condition described in the MCAI and service information referenced 
above. We are proposing this AD because we evaluated all the relevant 
information provided by EASA and determined the unsafe condition 
previously described is likely to exist or develop in other products of 
the same type design.

Proposed AD Requirements

    This proposed AD would require removal of the affected propeller 
blades and installation of the modified propeller blades marked with 
change letter ``A'' or ``B'' on the blade.

Differences Between This Proposed AD and the MCAI or Service 
Information

    EASA AD 2017-0220 partially restates the requirements of AD 83-150, 
issued on December 21, 1984, by German aviation authority Luftfahrt-
Bundesamt (LBA), which is based on Propellerwerk Hoffmann Rosenheim SB 
4, Revision C, dated February 20, 1984. EASA AD 2017-0220 also adds new 
requirements based on the issuance of

[[Page 32220]]

Hoffmann Propeller GmbH & Co. KG SB E34, Rev. B dated September 18, 
2017.
    In restating LBA AD 83-150, EASA AD 2017-0220 maintains a 
requirement to remove certain propellers from service within 10 flight 
hours after December 21, 1984, but not later than 31 March 31, 1985. 
Service Bulletin E34 requires a mandatory immediate maximum propeller 
rotational speed limitation until the permanent corrective action is 
completed, within 50 flight hours. The EASA AD 2017-0220 partially 
restated requirements of SB 4. Additionally, Hoffmann Propeller GmbH & 
Co. KG SB E34 Revision B and SB 4 Revision C temporarily prohibit 
acrobatic flight. EASA AD 2017-0220 also adds a new requirement for a 
mandatory maximum propeller rotational speed limitation within 30 days 
until the propeller is replaced within 50 flight hours.
    This proposed AD does not require a propeller speed limitation but 
would require removal of the affected propeller blades and installation 
of modified propeller blades within 30 days of the effective date of 
this AD.

Costs of Compliance

    We estimate that this proposed AD affects 50 propellers installed 
on airplanes of U.S. registry.
    We estimate the following costs to comply with this proposed 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.
    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 engines, propellers, and 
associated appliances to the Manager, Engine and Propeller Standards 
Branch, Policy and Innovation Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.
