What to do
Operators of Dassault Falcon 10 aeroplanes must inspect the System #2 hydraulic pipes within 24 months or 1,230 flight hours from 9 April 2020, whichever occurs first. If no chafing or interference is found, the affected areas must still be modified as per the service bulletin. If chafing or interference is detected, repairs and modifications must be completed before the next flight. Compliance with the Dassault Aviation Mandatory Service Bulletin F10-337 is required.
Summary
EASA Airworthiness Directive 2020-0072 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all Dassault Aviation Falcon 10 aeroplanes. It addresses inspection and modification requirements for the System #2 hydraulic pipes in the left and right wings, specifically targeting potential chafing and cracks that could lead to hydraulic fluid leakage. The directive mandates inspections and corrective actions to prevent possible fire hazards caused by hydraulic fluid leaks near the main landing gear brake assembly.
What changed
EASA Airworthiness Directive 2020-0072 introduces a new mandatory inspection and modification requirement for the System #2 hydraulic pipes powering the ailerons on Falcon 10 aircraft. It requires operators to inspect for chafing or interference and to repair or modify affected areas as necessary according to Dassault Aviation Service Bulletin F10-337. This AD does not supersede any previous directives and is a new regulation addressing a specific unsafe condition.
Why it matters
This directive is critical for aviation professionals because undetected hydraulic pipe chafing can lead to significant hydraulic fluid leaks, which pose a fire risk if combined with an ignition source. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and airworthiness. Compliance with this AD helps prevent potential in-flight failures and costly repairs due to hydraulic system damage.
