Summary
EASA Airworthiness Directive 2019-0040-E is an emergency directive addressing the inspection of wing anti-ice outboard flexible hoses, part number 115S018A315, installed on Dassault Aviation Falcon 10 aeroplanes. The directive mandates a one-time detailed inspection and, depending on findings, further inspections or replacement of the affected hoses to ensure continued airworthiness. It applies to all serial numbers of Falcon 10 aircraft and aims to prevent loss of wing anti-ice system performance.
What Changed
This directive introduces mandatory inspections of the wing anti-ice outboard flexible hoses due to reported damages likely caused during installation. It requires operators to inspect these hoses within specified flight cycle limits and replace any hoses that exceed acceptable damage criteria. Additionally, it sets conditions for the installation of these parts going forward, ensuring only serviceable parts are installed and inspected accordingly.
Why It Matters
This directive is critical for aviation professionals because damaged wing anti-ice hoses can lead to undetected loss of anti-ice system performance, potentially reducing aircraft control in icing conditions. Operators and maintenance teams must comply to maintain safety and regulatory compliance, preventing in-flight hazards related to ice protection system failures. Timely inspections and replacements help avoid operational disruptions and ensure continued airworthiness of Falcon 10 aircraft.
What To Do
Operators of Dassault Falcon 10 aeroplanes must perform a detailed inspection of the wing anti-ice outboard flexible hoses within the compliance times based on flight cycles since installation, with immediate action required before the next flight in icing conditions if damage is found. Damaged hoses exceeding acceptable limits must be replaced before further flight. Repetitive inspections are required until the hose accumulates 100 flight cycles, after which inspections may cease if damage remains within acceptable criteria. Installation of affected parts is only allowed if they are serviceable and inspected as required.
