What to do
Operators of affected EC 225 LP helicopters must perform eddy current inspections on all five yoke areas of each affected part within specified compliance times: within 55 flight hours or 1 month for Group 1 helicopters, and within 6 months for Group 2 helicopters. If cracks 10 mm or longer are found, the main rotor assembly must be replaced before next flight; smaller cracks require rework. Inspection results must be reported to Airbus Helicopters within 7 days. Compliance with EASA AD 2024-0205 inspections and reporting is also acceptable.
Summary
EASA Airworthiness Directive 2024-0125R1 is issued for Airbus Helicopters EC 225 LP models, addressing inspection requirements for main rotor rotating swashplate yokes with part numbers 332A31-3074-00 and 332A31-3074-01. The directive mandates eddy current inspections to detect cracks caused by Hydrogen Environmental Assisted Cracking in the yoke areas. It applies to all serial numbers except those delivered after 19 June 2024.
What changed
This revision of EASA AD 2024-0125 updates compliance by accepting the accomplishment of requirements from EASA AD 2024-0205 as a method of compliance. It supersedes the original AD 2024-0125 and incorporates updated inspection instructions and reporting procedures based on new findings and Airbus Helicopters' Alert Service Bulletin EC225-62-32-0001.
Why it matters
This AD is critical for ensuring the structural integrity of the main rotor swashplate yokes, which are susceptible to cracking that could lead to loss of helicopter control. Operators and maintenance organizations must comply to prevent potential catastrophic failures and ensure continued airworthiness. The directive also streamlines compliance by recognizing alternative methods, aiding maintenance planning and regulatory adherence.
