EASA AD 2019-0133
SUPERSEDED BY EASA AD 2020-0116
Summary
EASA Airworthiness Directive 2019-0133 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Dassault Aviation Falcon 900EX aeroplanes, serial numbers 1 to 119 inclusive except 97. It mandates compliance with updated airworthiness limitations specified in the Dassault Falcon 900EX Aircraft Maintenance Manual Chapter 5-40, Revision 16. This directive ensures continued airworthiness by enforcing maintenance tasks and life limits for components.
What Changed
EASA Airworthiness Directive 2019-0133 supersedes the previous AD 2016-0128 and introduces new and more restrictive maintenance tasks and life limits as detailed in Revision 16 of the Falcon 900EX AMM Chapter 5-40. It retains prior requirements but updates the maintenance program to reflect the latest approved airworthiness limitations. Operators must now comply with these updated tasks and intervals to maintain airworthiness.
Why It Matters
This directive is critical for aviation professionals because it mandates updated maintenance requirements that prevent unsafe conditions due to component wear or failure. Operators and maintenance organizations must adhere to these revised limitations to ensure regulatory compliance and aircraft safety. Failure to comply could result in grounding or unsafe operation of affected Falcon 900EX aircraft.
What To Do
Operators of affected Falcon 900EX aeroplanes must replace components before exceeding new life limits and perform all maintenance tasks within specified intervals starting from 25 June 2019. They must revise their approved Aircraft Maintenance Programme within 12 months of the effective date to incorporate the updated airworthiness limitations. Any discrepancies found during maintenance must be corrected according to Dassault instructions before further flight.
