What to do
Operators must inspect specified engine pylon areas within 48 months or 6600 flight hours from the AD's effective date and incorporate the new certification maintenance requirement task within 60 days. Subsequent inspections must follow intervals defined in the updated Maintenance Requirement Manual. Compliance with later approved revisions of the maintenance manual also satisfies the AD requirements.
Summary
Canadian Airworthiness Directive CF-2023-19 addresses missing insulation on the 14th stage bleed ducts of Mitsubishi Heavy Industries RJ Aviation ULC model CL-600-2B19 aircraft. This directive mandates inspections of the engine pylon structure and introduces a new certification maintenance requirement to ensure the integrity of the bleed duct insulation. The AD applies to all serial numbers of the CL-600-2B19 model.
What changed
This new Airworthiness Directive introduces a requirement for a visual inspection of the engine pylon structure and mandates the incorporation of a detailed inspection task for missing or damaged insulation on the 14th stage bleed ducts. It specifies compliance timelines and maintenance manual revisions to ensure ongoing inspection and correction of insulation issues.
Why it matters
The missing insulation on the 14th stage bleed ducts can cause heat damage to the engine pylon structure, potentially compromising structural integrity and safety. Operators, maintenance organizations, and compliance teams must address this to prevent structural failures and ensure continued airworthiness of affected aircraft. The directive helps maintain safety standards and regulatory compliance.
