Action
Notice of proposed rulemaking (NPRM).
Summary
We propose to supersede Airworthiness Directive (AD) 2013-03- 12 for all Dassault Aviation Model MYSTERE-FALCON 50 airplanes. AD 2013-03-12 currently requires revising the maintenance program to incorporate new or revised maintenance requirements and airworthiness limitations. Since we issued AD 2013-03-12, the manufacturer has issued a revision to the airplane maintenance manual (AMM) that introduces new or more restrictive maintenance requirements and/or airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate new or revised maintenance requirements and airworthiness limitations. We are proposing this AD to prevent reduced structural integrity of the airplane.
