CESSNA 310F — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) of Australia, specifically addressing safety concerns related to fuel regulator shutoff valves used in various aircraft, including the Cessna 310F. The directive outlines inspection and replacement requirements for the Kelly Aerospace fuel regulator shutoff valves and associated cabin heaters. It aims to mitigate risks of fuel leaks that could lead to fire hazards in the aircraft. The document provides compliance timelines and alternative methods for ensuring safety, emphasizing the importance of regular inspections and proper maintenance procedures. This AD is crucial for operators and maintenance personnel to ensure the airworthiness of affected aircraft models.

• Inspect fuel regulator shutoff valves for leaks within 25 hours after the AD's effective date.
• If leaks are found, replace the valve with a new one dated 02/02 or later.
• Logbook entries are required after each inspection, regardless of findings.
• Repetitive inspections must occur every 100 hours or 12 months, whichever comes first.
• Failure to comply with the AD could result in unsafe conditions leading to fire hazards.
