EASA AD 2026-0045
Rotors Flight Control — Collective Stick Torque Tube Assembly — Inspection / Replacement
Summary
EASA Airworthiness Directive 2026-0045 is an airworthiness directive addressing the collective stick torque tube assembly on Leonardo S.p.A. A119 and AW119MKII helicopters. It mandates inspections and replacement of affected collective stick torque tube assemblies with part number 109-0011-03-105 to ensure continued safe operation of these helicopter models.
What Changed
This directive supersedes EASA AD 2023-0035 and expands the replacement requirements by mandating the installation of improved serviceable parts with part number 109G6711A35-101. It retains inspection requirements but shortens inspection intervals and prohibits installation of affected parts from the effective date.
Why It Matters
The directive addresses a critical safety issue caused by manufacturing defects in certain collective stick torque tube assemblies that could lead to reduced helicopter control and potential forced landings. Compliance ensures operators maintain airworthiness and reduce risk of accidents, while MROs must update maintenance practices accordingly.
What To Do
Operators of A119 and AW119MKII helicopters must inspect affected torque tube assemblies within specified flight hour intervals and replace any defective parts before next flight. All affected parts must be replaced with serviceable parts within 12 months of the directive's effective date. Installation of affected parts is prohibited from the effective date onward.
