What to do
Operators of EC 175 B helicopters must perform repetitive detailed visual inspections and torque measurements on affected parts as specified, and replace any affected horizontal stabilizers, fittings, and bolts with serviceable parts. Group 1 helicopters must complete modifications by 30 June 2023 or within 2,400 flight hours after 6 August 2021, whichever is earlier. Group 2 helicopters must modify within 10 flight hours after the last inspection or before the next flight after the AD effective date. Installation of affected parts is prohibited from the effective date.
Summary
EASA Airworthiness Directive 2024-0064R1 is an updated regulatory requirement addressing the replacement of horizontal stabilizers on Airbus Helicopters EC 175 B models. It applies to all serial numbers of the EC 175 B and targets specific part numbers of horizontal stabilizers, fittings, and bolts. The directive mandates inspections and modifications to prevent potential loss of the horizontal stabilizer due to cracks, which could lead to loss of control of the helicopter.
What changed
EASA Airworthiness Directive 2024-0064R1 revises the previous AD 2024-0064 by correcting the definition of affected parts, specifically removing an erroneously included horizontal stabilizer fitting part number. It retains all prior requirements including prohibiting the installation of affected parts and mandates replacement of affected horizontal stabilizers. This revision ensures clarity and accuracy in the parts subject to the directive.
Why it matters
This directive is critical for aviation professionals as it addresses a serious safety risk involving structural cracks in the horizontal stabilizer of EC 175 B helicopters. Operators and maintenance organizations must comply to avoid potential catastrophic failure and ensure continued airworthiness. Compliance ensures regulatory adherence and prevents operational disruptions due to unapproved parts or overdue inspections.
