Action
Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to supersede Airworthiness Directive (AD) 2019-03-27, which applies to all Dassault Aviation Model Falcon 10 airplanes. AD 2019-03-27 requires repetitive detailed inspections of certain wing anti-ice outboard flexible hoses, and replacement of certain wing anti-ice outboard flexible hoses. Since the FAA issued AD 2019-03-27, an improved wing anti-ice flexible hose has been developed. This proposed AD would continue to require the actions in AD 2019-03- 27, and would add a new life limit for the improved wing anti-ice flexible hose, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
