What to do
Operators of Dornier 228-212 aeroplanes must inspect affected carbon brake assemblies before the next flight after 27 November 2006 and then at intervals not exceeding 50 flight hours or 150 flight cycles, whichever occurs first. If discrepancies are found, corrective actions must be taken before further flight, including contacting the manufacturer for approved instructions or replacing the brake assembly. Replacing affected parts with serviceable ones terminates the need for repetitive inspections.
Summary
EASA Airworthiness Directive 2019-0307R1 is an updated regulatory requirement addressing the inspection and replacement of carbon brake assemblies on Dornier 228-212 aeroplanes. It applies to specific carbon brake assemblies with part numbers 5009850-1, 5009850-2, 5009850-3, and 5009850-4. The directive mandates inspections to detect loose bolts and other discrepancies that could lead to brake assembly detachment and compromised aircraft control during landing or roll-out.
What changed
EASA Airworthiness Directive 2019-0307R1 revises the previous AD 2019-0307 by including reference to the ASB Revision 2, which introduces brake assembly modification as a terminating action. It also provides clarifications and updates the design approval holder to General Atomics AeroTec Systems GmbH. The revision adjusts inspection intervals and compliance instructions based on new findings about production errors in brake assemblies.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk involving the landing gear carbon brake assembly that could lead to loss of aircraft control. Operators and maintenance organizations must ensure compliance to prevent brake malfunction and potential accidents. The AD also clarifies inspection intervals and corrective actions, helping maintenance teams maintain aircraft airworthiness and regulatory compliance.
