CESSNA 310L — Airworthiness Directives

This document is an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority of Australia, specifically addressing the Cessna 310 series of aeroplanes. The directive outlines mandatory requirements for all models in the 310 series, including the 310L, regarding the installation of specific placards related to fuel management and operational limits. The purpose of these placards is to enhance safety by informing pilots of critical operational limitations, particularly concerning fuel levels and flap usage. Compliance with these directives is required to ensure the airworthiness of the aircraft and to mitigate risks associated with fuel management during flight operations.

• A placard stating "Operation With Less Than Ten (10) Gallons of Fuel in Each Main Tank is Prohibited" must be installed.
• For model 310L, a placard stating "Maximum Speed with 15 Degrees to Full Flap Shall Not Exceed 126 Kts" is required.
• Compliance with placard installation is required immediately and must be completed by 30 June 1993.
• Operators may certify the installation of the required placards themselves.
• Modification of main fuel tanks must be done according to Cessna SL ME69-16.
