Airworthiness Directives; Diamond Aircraft Industries GmbH Models DA 40 and DA 40F Airplanes

We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires changing the emergency open doors procedure by incorporation of a temporary revision into the FAA- approved airplane flight manual (AFM) for all airplanes. This AD also requires replacement of the passenger door retaining bracket with an improved design retaining bracket for certain airplanes. This AD was prompted by several reports of the rear passenger door departing the airplane in flight. We are issuing this AD to change the emergency open doors procedure and retrofit the rear passenger door retaining bracket, which if not corrected could result in the rear passenger door departing the airplane in flight.
