CESSNA P337 — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Federal Aviation Administration (FAA) concerning specific engine models manufactured by Teledyne Continental Motors. It primarily addresses compliance requirements for the IO-360, TSIO-360, and LTSIO-360 series engines, which are installed on various aircraft, including the Cessna 337 series. The directive mandates inspections and rework of certain engine components to prevent potential engine failures. Compliance is required prior to further flight unless previously accomplished.
