Mooney M20M Bravo — Airworthiness Directives

This document, titled 'SE-42 Guidance on V-Band Clamp Failures,' was adopted by the FAA as a safety enhancement on January 1, 2018. It addresses critical safety issues related to v-band clamp assemblies in general aviation aircraft, particularly focusing on preventing fatal accidents due to powerplant system failures. The document outlines the need for an appliance-specific directive to ensure proper inspection and replacement criteria for these components, which have been linked to several accidents involving exhaust leaks and inflight fires. The FAA is tasked with developing this guidance to enhance safety standards across the aviation community.

• The FAA is developing an appliance-specific document for v-band clamp assemblies to enhance safety.
• Historical accidents have linked v-band clamp failures to inflight fires and powerplant failures.
• Training materials regarding turbocharger failures are to be revised to improve pilot response.
