What to do
Operators of Leonardo AB212, AB412, and AB412EP helicopters equipped with affected tail rotor assemblies must replace these assemblies with serviceable ones within 5 flight hours from 19 March 2020. Only serviceable tail rotor hub and blade assemblies may be installed from the effective date onward. Compliance must follow the instructions in the applicable Leonardo Emergency Alert Service Bulletins 212-210 and 412-159.
Summary
EASA Airworthiness Directive 2020-0062-E is an emergency directive addressing the replacement of tail rotor hub and blade assemblies on Leonardo AB212, AB412, and AB412EP helicopters. It targets specific tail rotor blades with part number 212-010-750-133 that may have manufacturing defects. The directive mandates inspection and replacement to ensure continued airworthiness and flight safety.
What changed
This new emergency airworthiness directive introduces a mandatory replacement requirement for affected tail rotor hub and blade assemblies on specified Leonardo helicopter models. It identifies a batch of tail rotor blades with potential surface defects and requires operators to replace these with serviceable assemblies within a short compliance window. The directive also restricts installation to only serviceable assemblies from the effective date.
Why it matters
This directive is critical for aviation professionals as it addresses a potential safety risk that could lead to tail rotor blade failure and reduced helicopter control. Operators and maintenance organizations must act promptly to comply, ensuring the safety and regulatory compliance of affected helicopters. Failure to comply could result in unsafe flight conditions and regulatory penalties.
