EASA AD 2020-0275
SUPERSEDED BY EASA AD 2021-0244
Summary
EASA Airworthiness Directive 2020-0275 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting all serial numbers of PZL SW-4 helicopters manufactured by WSK “PZL – Świdnik” S.A. This directive mandates compliance with updated airworthiness limitations as specified in the PZL SW-4 Instructions for Continued Airworthiness - Maintenance Manual, Chapter 4, Revision 17 dated April 2020.
What Changed
This directive supersedes EASA AD 2019-0062 and introduces new and/or more restrictive maintenance tasks and life limits for PZL SW-4 helicopters. It requires operators to replace parts before exceeding updated life limits and to perform maintenance tasks within revised thresholds and intervals as defined in the latest airworthiness limitations document.
Why It Matters
Compliance with EASA Airworthiness Directive 2020-0275 is critical to ensure the continued airworthiness and safe operation of PZL SW-4 helicopters. Operators, maintenance organizations, and compliance teams must update their maintenance programs to reflect the new requirements to avoid unsafe conditions and regulatory non-compliance.
What To Do
Operators must replace life-limited parts within 10 days after the effective date or before exceeding life limits, whichever is later, and perform maintenance tasks within specified intervals. They must revise the approved Aircraft Maintenance Programme within 12 months to incorporate the updated maintenance tasks and life limits. Any discrepancies found during maintenance must be corrected before the next flight or as specified in the maintenance documentation.
