EASA AD 2024-0215R1
Main Rotor — Hub Sleeves — Inspection
Summary
EASA Airworthiness Directive 2024-0215R1 is an updated directive addressing inspection requirements for main rotor hub sleeves on Airbus Helicopters EC 225 LP models. It mandates repetitive inspections and, if necessary, replacement of affected main rotor hub sleeves with part number 332A31-3071-00 and associated blade pins to prevent structural failure. This directive applies to all serial numbers of the EC 225 LP helicopter.
What Changed
This revision extends the inspection interval for the affected main rotor hub sleeves based on further investigation and updates the associated Airbus Helicopters Emergency Alert Service Bulletin to issue 002 dated 9 February 2026. It revises the original AD 2024-0215-E by modifying inspection intervals and clarifying serviceable part definitions while maintaining the requirement for repetitive inspections and replacements as needed.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent potential structural failures caused by fatigue cracks in the main rotor hub sleeves, which could lead to loss of helicopter control. Compliance ensures continued airworthiness and safety of the EC 225 LP fleet. Understanding the updated inspection intervals helps optimize maintenance scheduling and resource allocation.
What To Do
Operators must perform inspections of each affected main rotor hub sleeve before the first flight of the day after 18 November 2024, not exceeding 8 flight hours from that date, and subsequently at intervals not exceeding 15 flight hours or before the first flight of the day, whichever occurs first. If cracks are found, the affected part and its blade pins must be replaced before the next flight. Only serviceable parts as defined in the directive may be installed from 18 November 2024 onward.
