The FAA is adopting a new airworthiness directive (AD) for Diamond Aircraft Industries Models DA 40, DA 40 F, and 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 deterioration of the fuel tank connection hoses that could result in restriction of fuel flow leading to fuel starvation and reduced control of the airplane. The FAA is issuing this AD to require actions to address the unsafe condition on these products.

Airworthiness Directives; Diamond Aircraft Industries Inc. Airplanes
The FAA is superseding Airworthiness Directive (AD) 2020-14- 06, which applied to all Diamond Aircraft Industries Inc. (DAI) Model DA 40, DA 40 F, and DA 40 NG airplanes. AD 2020-14-06 required replacing affected parts, inspecting the fuel tank chambers, and removing rubber material that has detached from the fuel tank connection hoses. AD 2020-14-06 also prohibited installing an affected part on any airplane. Since the FAA issued AD 2020-14-06, additional affected parts installed during production on Model DA 40 NG airplanes have been reported. As a result, the manufacturer has published updated service material for the Model DA 40 NG. This AD requires the same actions as AD 2020-14-06 and requires updated service material to be used for the Model DA 40 NG airplanes. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Diamond Aircraft Industries Inc. (Type Certificate Previously Held by Diamond Aircraft Industries GmbH) Airplanes
The FAA is superseding Airworthiness Directive (AD) 2009-10-04 for certain Diamond Aircraft Industries GmbH (type certificate now held by Diamond Aircraft Industries Inc.) Model DA 40 and DA 40 F airplanes. AD 2009-10-04 required repetitively inspecting the nose landing gear (NLG) leg for cracks and replacing the NLG leg if cracks are found. Since the FAA issued AD 2009-10-04, Transport Canada updated mandatory continuing airworthiness information (MCAI) to correct this unsafe condition on these products. This AD results from changes made to the part replacement options and the repetitive inspections. This AD requires doing repetitive detailed inspections of the NLG leg pivot axle for cracking and if cracking is found replacing that part with a serviceable part. This AD also requires eventually replacing all NLG legs having certain part numbers with serviceable parts, if not already done, and prohibits installing affected parts. Replacing affected parts with serviceable parts is terminating action for the repetitive inspections specified in this AD. The FAA is issuing this AD to address the unsafe condition on these products.

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.
