Applicability*9

This AD applies to all Austro Engine GmbH model E4 and E4P diesel piston engines.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Within the compliance times identified in Table 1 to paragraph (g) of this AD, and thereafter at intervals not to exceed 250 flight hours (FHs), replace the waste gate controller and control rod circlip in accordance with the Accomplishment Instructions, Paragraph 2.1, of Austro Engine GmbH Mandatory Service Bulletin (MSB) No. MSB-E4-022/2, Rev. No. 2, dated November 27, 2017. ER12AP18.002

Unsafe condition

This AD was prompted by reports of broken or disconnected turbocharger waste gate control rods on some engines. We are issuing this AD to prevent failure of the turbocharger waste gate control rod. The unsafe condition, if not addressed, could result in loss of engine thrust control and reduced control of the airplane.

Affected ADs

None.
