## Abstract

We are adopting a new airworthiness directive (AD) for Diamond Aircraft Industries Model DA 40 NG airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as chafing between the charge air tubing and the engine firewall that may cause a hole in the charge air tubing, which could result in loss of charged air pressure with consequent loss of engine power and loss of control. We are issuing this AD to require actions to address the unsafe condition on these products.
