AD 2021-24-10 Requires Replacing A Certain Oil Pump As Well As The Oil Filter And Engine Oil
The FAA is superseding Airworthiness Directive (AD) 2021-09-04 for all Austro Engine GmbH E4 and E4P model diesel piston engines.
AD 2021-09-04 required replacing a certain oil pump as well as the oil filter and engine oil. This AD was prompted by reports of an oil pump blockage on E4 model diesel piston engines. This AD requires replacing a certain oil pump as well as the oil filter and engine oil. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective December 27, 2021.
Supplementary Information: The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2021-09-04, Amendment 39-21517 (86 FR 21637, April 23, 2021), (AD 2021-09-04). AD 2021-09-04 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) E4A-50-000-BHY. 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. MSB-E4-030/4, Revision No. 4, dated March 30, 2021. In the NPRM, the FAA also proposed to require replacement of the oil filter and engine oil.
