AI-generated summary of the official EASA document. Verify against the PDF before acting.
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 Revision NC or later. If damage is found or inspection criteria are not met, the ejector pipe and seal must be replaced. Repetitive inspections are required every 6600 flight hours thereafter, and installation of certain inlet cowl assemblies with 6600 or more flight hours is prohibited unless inspected and found acceptable.
Summary
The Canadian Airworthiness Directive CF-2026-07R1 titled 'Ice and Rain Protection – Engine Cowl Anti-Ice – Ejector Pipe Chafing' applies to all serial numbers of the MHI RJ Aviation ULC model CL-600-2B19 aircraft. It addresses chafing damage to the engine cowl anti-ice ejector pipe and seal, which can lead to system degradation, ice accumulation, and potential engine shutdown. The directive mandates inspections and corrective actions to ensure continued airworthiness.
What changed
This revision CF-2026-07R1 corrects the inlet cowl assembly part numbers listed in the original AD CF-2026-07 issued on 4 February 2026. It maintains the original inspection and replacement requirements but updates Part IV to reference the correct cowl assembly part numbers. No other changes to the compliance or inspection procedures were made.
Why it matters
This directive is critical for operators and maintenance organizations to prevent unannunciated failures of the engine cowl anti-ice system that could lead to ice ingestion and engine shutdown. Ensuring compliance helps maintain flight safety and avoids potential in-flight engine issues. Accurate part number references are essential for proper maintenance and parts replacement.
