Airworthiness Directive 2013-14-08
one-timeAirworthiness Directives; Austro Engine GmbH Engines
What this AD requires
We are adopting a new airworthiness directive (AD) for all Austro Engine GmbH model E4 engines. This AD requires removing from service certain part number waste gate controllers. This AD was prompted by several reports of power loss events due to fracture of the waste gate controller lever. We are issuing this AD to prevent engine power loss or in-flight shutdown, which could result in loss of control and damage to the airplane.
Which aircraft AD 2013-14-08 applies to
Applies to engines with a waste gate controller P/N E4A-41-120-000 Rev. 050 or lower revision, or P/N E4B-41-120-000 Rev. 000, installed.
Whether AD 2013-14-08 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
