Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for all DASSAULT AVIATION Model MYSTERE-FALCON 50 airplanes. This proposed AD was prompted by a manufacturer revision to the airplane maintenance manual (AMM) that introduces new or more restrictive maintenance requirements and airworthiness limitations. This proposed AD would revise the maintenance program to incorporate new or revised maintenance requirements and airworthiness limitations. We are proposing this AD to prevent reduced structural integrity of the airplane.
