What to do
Operators must perform a borescope inspection of the ejector pipe and seal within 6600 flight hours from 18 February 2026, following the procedures in MHIRJ Service Bulletin SB 601R-30-035. If damage is detected, replacement of the ejector pipe and seal is required. Repetitive inspections must continue every 6600 flight hours, and installation of specific inlet cowl assemblies is prohibited unless inspected and approved.
Summary
EASA Airworthiness Directive CF-2026-07 addresses ice and rain protection issues related to engine cowl anti-ice ejector pipe chafing on MHI RJ Aviation ULC model CL-600-2B19 aircraft. The directive mandates inspections and possible replacement of the ejector pipe and seal to prevent system degradation and engine shutdown. It applies to all serial numbers of the specified aircraft model.
What changed
This new Airworthiness Directive introduces mandatory borescope inspections of the engine cowl anti-ice ejector pipe and seal within 6600 flight hours, with required replacement if damage is found. It also prohibits installation of certain inlet cowl assemblies exceeding 6600 flight hours without prior inspection. Repetitive inspections at 6600-hour intervals are required thereafter.
Why it matters
This directive is critical for aviation professionals to prevent unannounced failures of the cowl anti-icing system that could lead to ice accumulation and engine shutdown. Operators and maintenance organizations must ensure compliance to maintain aircraft safety and airworthiness. The directive also impacts parts management by restricting installation of certain inlet cowl assemblies without inspection.
