What to do
Operators must perform general visual inspections before the next flight after 7 May 2026 and every 200 flights thereafter, and detailed inspections within 300 flight hours or 12 months, repeating at these intervals. If cracks or indications of cracks are found, a special detailed inspection must be done before further flight. The affected torsion tube assembly must be replaced with the serviceable part as soon as discrepancies are found, and from the effective date, installation of the affected part is prohibited. Replacement with the serviceable part terminates the need for repetitive inspections.
Summary
EASA Airworthiness Directive PAD No. 26-095 is a proposed directive addressing the inspection and replacement requirements for the airbrake control torsion tube assembly on Allstar PZL Glider Sp. z o.o. SZD-54-2 "Perkoz" sailplanes. It applies to all serial numbers of this sailplane model and focuses on the control lever - torsion tube assembly part number 540.64.30.00. The directive aims to ensure continued airworthiness by preventing cracks that could impair airbrake functionality.
What changed
This proposed directive supersedes EASA AD 2026-0086 and retains its inspection requirements while introducing a mandatory replacement of the affected torsion tube assembly with a newly designed serviceable part (P/N 542.64.30.00A) to address fatigue-related cracking. It changes the corrective action from repetitive inspections to part replacement as a terminating action for the unsafe condition.
Why it matters
This directive is critical for operators and maintenance organizations to prevent potential loss of airbrake function, which could lead to reduced control or loss of control during flight or landing. Compliance ensures the structural integrity of the airbrake system and maintains flight safety for the SZD-54-2 "Perkoz" sailplanes. It also impacts maintenance planning by introducing a terminating modification that replaces ongoing inspection requirements.
