EASA AD 2020-0249R1-CN
CANCELLED: Instruments — Angle of Attack Probe and Multi-Function Computers Electrical Routing — Operational Test / Inspection
Summary
EASA Airworthiness Directive Cancellation Notice 2020-0249R1-CN is a cancellation notice issued by the European Union Aviation Safety Agency for ATR 42 and ATR 72 aeroplanes. This notice cancels the previous AD 2020-0249R1, which addressed operational testing and inspection of electrical wiring between Angle of Attack probes and Multi-Function Computers. The cancellation reflects that the required actions have been incorporated into the ATR 42 and ATR 72 Time Limits Documents and new ADs have been issued to cover those requirements.
What Changed
EASA Airworthiness Directive Cancellation Notice 2020-0249R1-CN officially cancels the previous AD 2020-0249R1, removing the requirement for repetitive operational testing and one-time wiring inspections related to the Angle of Attack probes and Multi-Function Computers. The actions previously mandated by AD 2020-0249R1 are now included in the ATR 42 and ATR 72 Time Limits Documents and addressed by newer ADs 2024-0052 and 2024-0053.
Why It Matters
This cancellation simplifies compliance for operators and maintenance organizations by consolidating safety requirements into updated Time Limits Documents and newer ADs. It reduces redundant inspections and testing, allowing operators to follow a streamlined maintenance program while ensuring continued safety of the stall warning system on ATR 42 and ATR 72 aircraft. Compliance teams can update their records to reflect the cancellation and focus on the current applicable directives.
What To Do
Affected operators and maintenance providers should note that there are no new actions required by this cancellation notice. They should ensure compliance with the requirements now specified in ATR 42 Time Limits Document Revision 18, ATR 72 Time Limits Document Revision 22, and EASA ADs 2024-0052 and 2024-0053. No further operational tests or inspections under AD 2020-0249R1 are necessary after the effective date.
