The FAA proposes to supersede Airworthiness Directive (AD) 2017-18-10, which applies to certain Diamond Aircraft Industries GmbH (DAI) Model DA 42, DA 42 M-NG, and DA 42 NG airplanes. AD 2017-18-10 requires modifying the flap control system, repetitively inspecting the flap bell crank, and replacing the flap bell crank as necessary. Since the FAA issued AD 2017-18-10, the European Union Aviation Safety Agency (EASA) superseded its mandatory continuing airworthiness information (MCAI) to correct an unsafe condition on these products. This proposed AD would retain the actions required by AD 2017-18-10, expand the applicability, and prohibit the installation of certain flap bell cranks. The FAA is proposing this AD to address the unsafe condition on these products.
