EASA AD 2019-0242
Aircraft Flight Manual — Use of the Disc Braking System — Amendment
Summary
EASA Airworthiness Directive 2019-0242 is an amendment concerning the use of the disc braking system on CEAPR DR 400 aeroplanes, including various DR 400 models up to serial number 2668. This directive addresses safety issues related to brake and wing fires caused by incorrect use of the disc braking system. It applies to aircraft equipped with disc brakes and not modified by CEAPR modification DET150102.
What Changed
This directive requires the incorporation of the CEAPR Aircraft Flight Manual Supplement 1003059 into the Aircraft Flight Manual to provide improved instructions for the use of the disc braking system. It also mandates operators to follow the CEAPR Mandatory Service Bulletin 190101, which identifies different disc braking systems and outlines good operational and maintenance practices. This is a new safety requirement rather than a superseding amendment.
Why It Matters
This directive is important for aviation professionals because it addresses a critical safety risk of brake and wing fires on DR 400 aeroplanes, which could cause damage and injury. Operators and maintenance organizations must update flight manuals and procedures to ensure correct brake system usage, thereby enhancing safety and regulatory compliance. Compliance helps prevent accidents and supports continued airworthiness of affected aircraft.
What To Do
Operators must amend the applicable Aircraft Flight Manual by incorporating the CEAPR Aircraft Flight Manual Supplement within 12 months of the effective date, which is 10 October 2019. They must also inform all pilots of the changes and operate the aircraft according to the updated manual. Maintenance organizations should follow the instructions in the CEAPR Mandatory Service Bulletin 190101 to implement the supplement correctly.
