What to do
Operators must verify the calendar age of main and nose landing gear components within 90 days of the directive's effective date. Components aged 10 years or more must be removed and replaced within compliance times ranging from 6 months to 36 months depending on age. Installation of components aged 12 years or more without overhaul is prohibited from the effective date onward.
Summary
Canadian Airworthiness Directive CF-2021-49 addresses the landing gear system for MHI RJ Aviation ULC model CL-600-2C10, CL-600-2C11, CL-600-2D15, CL-600-2D24, and CL-600-2E25 aircraft. It mandates verification of the calendar age of main and nose landing gear components and requires removal and replacement of components older than 10 years. The directive aims to prevent landing gear collapse due to corrosion by enforcing maintenance and overhaul standards.
What changed
This new Airworthiness Directive introduces mandatory verification of landing gear component ages and enforces removal and replacement of components exceeding specified calendar age limits. It prohibits installation of landing gear components aged 12 years or more without overhaul. The directive also sets specific compliance times based on component age to mitigate corrosion risks.
Why it matters
This directive is critical for operators and maintenance organizations to ensure landing gear integrity and safety, reducing the risk of gear collapse and potential injuries. Compliance helps maintain airworthiness and prevents costly damage or accidents related to aging landing gear components. It also clarifies maintenance record verification and overhaul requirements for affected aircraft.
