## Abstract

We are adopting a new airworthiness directive (AD) for various aircraft equipped with a BRP-Rotax GmbH & Co. KG (formerly BRP- Powertrain GmbH & Co. KG; Bombardier-Rotax GmbH & Co. KG; Bombardier- Rotax GmbH) 912 A series engine. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as defective valve push-rod assemblies manufactured from June 8, 2016, through October 2, 2017. We are issuing this AD to require actions to address the unsafe condition on these products.
