## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to Bombardier-Rotax GmbH 914 F series reciprocating engines. This action requires initial and repetitive inspections of certain exhaust bend assemblies, which are located between the cylinder heads and exhaust manifold assembly. This amendment is prompted by reports of cracks found in exhaust bend assemblies. The actions specified in this AD are intended to prevent carbon monoxide from entering the cabin and also to prevent the possibility of an engine fire.
