SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Austro Engine GmbH model E4 and E4P diesel piston engines. The NPRM published in the Federal Register on March 20, 2020 (85 FR 16014). The NPRM was prompted by reports of considerable wear of the timing chain and failure of fuel injectors on these engines. The NPRM proposed to require replacement of the timing chain and fuel injectors on the affected Austro Engine GmbH model E4 and E4P diesel piston engines. The FAA is issuing this AD to address the unsafe condition on these products. The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA AD 2019–0041, dated February 25, 2019 (referred to after this as ‘‘the MCAI’’), to address the unsafe condition on these products. The MCAI states: The airworthiness limitations and maintenance tasks for the Austro Engine E4 and E4P engines, which are approved by EASA, are currently defined and published in the Austro Engine MM, Chapter 04. These PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in an unsafe condition. Austro Engine recently revised the ALS, introducing life limit for the engine timing chain and for the fuel injectors. For the reason described above, this [EASA] AD requires accomplishment of the actions specified in the ALS. You may obtain further information by examining the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2019– 1113. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA 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. Related Service Information Under 1 CFR Part 51 The FAA reviewed Austro Engine Mandatory Service Bulletin (MSB) No. MSB–E4–025, Rev. No. 3, dated January 8, 2019. The MSB describes procedures for replacing the fuel injectors. 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. Other Related Service Information The FAA reviewed Austro Engine Maintenance Manual (MM) Temporary Revision (TR) MM–TR–MDC–E4–454, dated October 3, 2018. The MM TR updates the time limits for the fuel injectors and timing chain and describes procedures for updating the Airworthiness Limitation Section in the existing approved MM. Costs of Compliance The FAA estimates that this AD affects 263 engines installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\21JYR1.SGM 21JYR1 43988 Federal Register / Vol. 85, No. 140 / Tuesday, July 21, 2020 / Rules and Regulations ESTIMATED COSTS Action Labor cost Replace the timing chain ................................

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to all Austro Engine GmbH 
model E4 and E4P diesel piston engines. The NPRM published in the 
Federal Register on March 20, 2020 (85 FR 16014). The NPRM was prompted 
by reports of considerable wear of the timing chain and failure of fuel 
injectors on these engines. The NPRM proposed to require replacement of 
the timing chain and fuel injectors on the affected Austro Engine GmbH 
model E4 and E4P diesel piston engines. The FAA is issuing this AD to 
address the unsafe condition on these products.
    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community, has 
issued EASA AD 2019-0041, dated February 25, 2019 (referred to after 
this as ``the MCAI''), to address the unsafe condition on these 
products. The MCAI states:
    The airworthiness limitations and maintenance tasks for the Austro 
Engine E4 and E4P engines, which are approved by EASA, are currently 
defined and published in the Austro Engine MM, Chapter 04. These 
instructions have been identified as mandatory for continued 
airworthiness.
    Failure to accomplish these instructions could result in an unsafe 
condition.
    Austro Engine recently revised the ALS, introducing life limit for 
the engine timing chain and for the fuel injectors. For the reason 
described above, this [EASA] AD requires accomplishment of the actions 
specified in the ALS.
    You may obtain further information by examining the MCAI in the AD 
docket on the internet at https://www.regulations.gov by searching for 
and locating Docket No. FAA-2019-1113.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA 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.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Austro Engine Mandatory Service Bulletin (MSB) No. 
MSB-E4-025, Rev. No. 3, dated January 8, 2019. The MSB describes 
procedures for replacing the fuel injectors. 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.

Other Related Service Information

    The FAA reviewed Austro Engine Maintenance Manual (MM) Temporary 
Revision (TR) MM-TR-MDC-E4-454, dated October 3, 2018. The MM TR 
updates the time limits for the fuel injectors and timing chain and 
describes procedures for updating the Airworthiness Limitation Section 
in the existing approved MM.

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.

Regulatory Findings
