## Summary

We propose to adopt a new airworthiness directive (AD) for all Diamond Aircraft Industries GmbH Models DA 40 and DA 40F airplanes. This proposed AD would change the emergency open doors procedure by incorporation of a temporary revision into the FAA-approved airplane flight manual for all airplanes. This proposed AD would also require replacement of the passenger door retaining bracket with an improved design retaining bracket for certain airplanes. This proposed AD results from several reports of the rear passenger door departing the airplane in flight. We are proposing 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.
