EASA AD 2026-0022-E
Fuselage — Intermediate Fuselage Frame 8 — Inspection
Summary
EASA Airworthiness Directive 2026-0022-E is an emergency directive addressing Airbus Helicopters EC 175 B models. It mandates inspections of the intermediate fuselage frame 8 for cracks and loose rivets to ensure structural integrity and prevent potential tail boom detachment. The directive applies to all serial numbers of the EC 175 B helicopter.
What Changed
This new directive introduces mandatory repetitive inspections of the right-hand top corner of frame 8 in the intermediate fuselage. It requires operators to perform detailed inspections within specified flight hour thresholds and to carry out corrective actions if any cracks or loose rivets are found. The directive is an interim measure pending further actions.
Why It Matters
This directive is critical for maintaining the structural safety of the EC 175 B helicopter, preventing possible loss of control due to structural failure. Operators, maintenance organizations, and compliance teams must prioritize these inspections to avoid unsafe conditions and ensure regulatory compliance. Failure to comply could lead to grounding or operational restrictions.
What To Do
Operators must perform an initial detailed inspection of frame 8 within the specified flight hour limits—before exceeding 400 flight hours if the helicopter has 390 or fewer hours, or within 10 flight hours if more than 390 hours are accumulated. Subsequent inspections must occur every 200 flight hours. If cracks or loose rivets are detected, approved repair instructions from Airbus Helicopters must be followed before further flight.
