## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Diamond Aircraft Industries GmbH Models DA 42, DA 42 NG, and DA 42 M-NG airplanes. This proposed AD was prompted by mandatory continuing airworthiness information (MCAI) originated 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 failure of the nose landing gear (NLG) actuator attachment lever and detachment from the NLG leg. This proposed AD would require repetitively inspecting the NLG actuator attachment lever for cracks and damage and taking any necessary corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
