FAA Issues Airworthiness Directive for Certain Learjet Models

The Federal Aviation Administration (FAA) has issued an airworthiness directive (AD) for certain Learjet models, requiring a revision to the Airplane Flight Manual to prohibit flights above 41,000 feet. The directive aims to prevent cracking and subsequent failure of safety valves due to an improper molding process.
