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 8800 flight hours from 19 February 2026, replacing components if damage is found. Repetitive inspections are required every 8800 flight hours thereafter. Installation of certain inlet cowl assemblies with 8800 or more hours is prohibited unless inspected and approved per the directive. Compliance with the latest MHIRJ Service Bulletin SB 670BA-30-026 Revision B or later is mandatory.
Summary
Airworthiness Directive CF-2026-09R2 addresses ice and rain protection issues related to engine cowl anti-ice ejector pipe chafing on MHI RJ Aviation ULC model CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 aircraft. This directive mandates inspections and potential replacement of the ejector pipe and seal to prevent ice accumulation and engine shutdown. It applies to all serial numbers of the affected aircraft models.
What changed
CF-2026-09R2 corrects an error in the Service Bulletin definition found only in the English version of the previous revision CF-2026-09R1. It maintains the inspection, replacement, and installation requirements established in the original AD CF-2026-09 and its first revision. The directive clarifies compliance language without changing the core safety actions.
Why it matters
This directive is critical for operators and maintenance organizations to prevent unannunciated degradation of the engine cowl anti-icing system caused by ejector pipe chafing. Failure to comply could result in ice ingestion and engine shutdown, posing safety risks. Compliance ensures continued airworthiness and regulatory adherence for affected aircraft.
