SUPPLEMENTARY INFORMATION:
Background The FAA issued a notice of proposed rulemaking NPRM to amend 14 CFR
part 39 to supersede AD 20210904, Amendment 3921517 86 FR 21637, April 23, 2021, AD 20210904. AD
20210904 applied to all Austro Engine GmbH E4 and E4P model diesel piston engines. The NPRM published in the Federal Register on September 14, 2021 86 FR 51026. The NPRM was prompted by reports of an oil pump blockage on E4 model diesel piston engines caused by oil contamination with casting sand from the production process of oil pump part number P/N
E4A50000BHY. The root cause was found to be an improperly performed sand casted oil pump housing cleaning process. In the NPRM, the FAA
proposed to continue to require replacement of an affected oil pump, identified by P/N and serial number S/
N in Austro Engine GmbH Mandatory Service Bulletin No. MSBE4030/4, Revision No. 4, dated March 30, 2021.
In the NPRM, the FAA also proposed to require replacement of the oil filter and engine oil.
Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the costs.
Conclusion The FAA reviewed the relevant data and determined that air safety requires adoption of the AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these products. This AD is adopted as proposed in the NPRM.

Authority for This Rulemaking
Regulatory Findings
Title 49 of the United States Code specifies the FAAs 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 Agencys 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
The FAA has determined that 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,
