Airworthiness Directive · Amendment 39-17884 · Wings
Diamond Aircraft Industries GmbH Airplanes
This AD applies to Diamond Aircraft Industries Model DA 40 airplanes, serial numbers 40.006 through 40.009, 40.011 through 40.1071, and 40.1073 through 40.1077; and Model DA 40 F airplanes, serial numbers 40.FC001 through 40.FC029; certificated in any category.
We are superseding Airworthiness Directive (AD) 2013-24-14 for Diamond Aircraft Industries GmbH Models DA40 and DA40F airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the fatigue strength found in the aft main spar not ensuring unlimited lifetime structural integrity. We are issuing this AD to require actions to address the unsafe condition on these products.
