What to do

Operators must amend the applicable Airplane Flight Manual within 30 days after 18 November 2019 to include the new normal procedures for manual activation of probe heating during line up. Flight crews must be informed of these changes and operate the aircraft accordingly. Incorporating later AFM revisions that include these changes is also acceptable for compliance.

Summary

EASA Airworthiness Directive 2019-0273R1 is an amendment addressing the Falcon 900EX and Falcon 2000EX aeroplanes equipped with Dassault's EASy configurations. It mandates changes to the Airplane Flight Manual normal procedures to prevent icing of angle of attack and pitot probes during take-off. This directive ensures safer operation by requiring flight crews to manually activate probe heating during line up.

What changed

This amendment revises the applicability criteria to exclude aeroplanes that have incorporated specific Dassault service bulletins in service or production. It also clarifies the reason for the directive and updates the Airplane Flight Manual change proposals required for compliance. The directive replaces the original EASA AD 2019-0273 issued on 4 November 2019.

Why it matters

This directive is critical for operators and maintenance teams because it addresses a safety risk involving iced sensors that can cause misleading stall warnings and airspeed indications. Compliance reduces the risk of blocked angle of attack probes, which could compromise aircraft control during critical phases of flight. Ensuring the AFM is updated and crews are informed improves operational safety and regulatory compliance.
