What to do
Operators must amend the Rotorcraft Flight Manual and supplements of all affected PZL SW-4 helicopters within 30 days after 19 April 2023 by incorporating the specified updates. Pilots must be informed of the changes and operate the helicopter according to the new instructions. Later revisions containing the same content are acceptable for compliance.
Summary
EASA Airworthiness Directive 2023-0072 is an amendment applicable to all serial numbers of PZL SW-4 helicopters manufactured by WSK “PZL-ŚWIDNIK” S.A. This directive addresses a safety concern related to simulated hydraulic system failures during training flights. It mandates updates to the Rotorcraft Flight Manual and its supplements to include new operational instructions for safe handling under these conditions.
What changed
This directive requires incorporation of an updated Rotorcraft Flight Manual and related supplements that provide specific operating instructions and limitations for simulating hydraulic system failures. The update aims to mitigate excessive control forces experienced below 45 knots airspeed during such simulations. It introduces mandatory amendments to the flight manual within 30 days of the effective date.
Why it matters
This amendment is critical for flight crews and operators as it reduces the risk of excessive pilot workload and potential loss of helicopter control during hydraulic failure simulations. Compliance ensures safer training operations and helps maintain the continuing airworthiness of PZL SW-4 helicopters. Maintenance and compliance teams must ensure the updated manuals are incorporated to meet regulatory requirements.
