                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.
                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:

                 hour = $212.50.
                ----------------------------------------------------------------------------------------------------------------
                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.
