What to do
Operators of EC 130 B4 and EC 130 T2 helicopters must inspect the tail rotor hub tension-torsion bars within 330 flight hours or 12 months from 27 June 2024, whichever occurs first. If any defects are found, the affected parts must be replaced before the next flight. Maintenance procedures must follow the updated Airbus Helicopters Alert Service Bulletin EC130-64-00-0001 and revised Aircraft Maintenance Manual tasks dated 5 March 2024 or later.
Summary
EASA Airworthiness Directive 2024-0113 is an airworthiness directive addressing Airbus Helicopters EC 130 B4 and EC 130 T2 models. It mandates inspection of the tail rotor hub tension-torsion bars, specifically parts with P/N 350A33318000 or P/N 350A33318001, due to a reported failure that could lead to loss of tail rotor function. The directive includes inspection procedures and corrective actions to ensure continued safe operation.
What changed
This new directive introduces mandatory inspections of the tail rotor hub tension-torsion bars on affected EC 130 helicopters. It requires operators to inspect these parts within specified flight hours or time limits and replace any parts found with defects. Additionally, it updates maintenance manual tasks to reflect revised inspection instructions.
Why it matters
This directive is critical for aviation professionals because failure to detect damage in the tension-torsion bars could result in loss of tail rotor anti-torque function, potentially causing loss of helicopter control. Operators and maintenance organizations must comply to ensure safety and regulatory adherence, preventing costly incidents and grounding of aircraft.
