SUPERSEDED BY EASA AD 2019-0074
Summary
EASA Airworthiness Directive 2017-0191R2 is an updated safety directive addressing Airbus Helicopters EC 225e LP models equipped with main rotor rotating swashplate part numbers 332A31-3074-00 or 332A31-3074-01. The directive mandates inspections and rework of the main rotor rotating swashplate yokes to detect and correct cracks caused by aging, which could lead to structural failure and loss of helicopter control.
What Changed
This revision clarifies the compliance times for inspections and strip inspections of the affected swashplate yokes following updates to the related Airbus Helicopters Emergency Alert Service Bulletin. It extends inspection intervals and corrects manufacturing date errors in the previous service bulletin, ensuring accurate identification of affected parts and compliance requirements.
Why It Matters
This directive is critical for maintaining the structural integrity of the main rotor control system on EC 225e LP helicopters, directly impacting flight safety. Operators, maintenance organizations, and compliance teams must adhere to the inspection and rework schedules to prevent potential control failures and ensure continued airworthiness.
What To Do
Operators must perform repetitive inspections of the main rotor rotating swashplate yokes within specified compliance times and intervals not exceeding 15 flight hours or 7 days. Strip inspections and rework must be completed before exceeding 100 flight hours after the swashplate reaches 7 years of age. Any detected cracks require immediate replacement of the swashplate before further flight. Installation of affected swashplates is permitted only if they are under 7 years old or have passed the required strip inspection and rework.
