EASA AD 2018-0190
Landing Gear - Nose Landing Gear A-Frame / Liner - Inspection
Summary
EASA Airworthiness Directive 2018-0190 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus Helicopters EC 175 B models. It mandates inspection of the nose landing gear A-frame and liner assembly to ensure correct installation and presence of critical components. The directive aims to prevent potential nose landing gear failure during landing.
What Changed
This new airworthiness directive introduces a one-time inspection requirement for the nose landing gear A-frame and liner on all EC 175 B helicopters. It specifies inspection procedures, corrective actions including replacement or reinstallation of parts, and reporting obligations to Airbus Helicopters. It also prohibits installation of certain parts removed from service unless properly corrected and released.
Why It Matters
This directive is critical for operators and maintenance organizations to prevent nose landing gear failure, which could cause damage to the helicopter and risk occupant safety. Compliance ensures continued airworthiness and regulatory adherence, reducing the risk of in-flight incidents related to landing gear malfunction. It also provides clear guidance on corrective actions and record-keeping to maintain safety standards.
What To Do
Operators must inspect the nose landing gear A-frame and liner during the next after-last-flight inspection or within 30 days of 7 September 2018, whichever comes first. Maintenance records must be checked within 5 days for previous findings of incorrect installation or missing liners. If defects are found, corrective actions including part replacement or reinstallation must be completed before the next flight. All findings must be reported to Airbus Helicopters within 30 days of inspection.
