Airworthiness Directive 2018-10-10

What this AD requires
We are superseding Airworthiness Directive (AD) 2017-01-12, AD 2017-11-08, and AD 2017-15-09 for certain Diamond Aircraft Industries GmbH Model DA 42 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as uncommanded engine shutdown during flight due to failure of the propeller-regulating valve caused by hot exhaust gases coming from fractured engine exhaust pipes. We are issuing this AD to require actions to address the unsafe condition on these products.
Which aircraft AD 2018-10-10 applies to
Applies to DA 42 airplanes with a TAE 125-02-99 or TAE 125-02-114 engine installed and equipped with either the original engine exhaust pipe (DAI P/N D60-9078-06-01 or Technify P/N 52-7810-H0001 02/03/04) or a modified engine exhaust pipe (DAI P/N D60-9078-06-01_01 or Technify P/N 52-7810-H0014 01).
Whether AD 2018-10-10 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.
