Airworthiness Directives; Diamond Aircraft Industries Inc. 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.
