EASA AD 2025-0285: Wings — Main Wing Spar — Inspection

What to do

Operators of affected CARAT A powered sailplanes must perform a one-time visual inspection of the bonding on the main wing spars within specified compliance times ranging from before the next flight to within 10 flight cycles, depending on the aircraft serial number. If any bonding discrepancies are found, repairs must be completed before further flight following the instructions in AMS-FLIGHT d.o.o. Service Bulletin SB 02. Compliance deadlines vary by serial number as detailed in the directive.

Summary

EASA Airworthiness Directive 2025-0285 is an airworthiness directive addressing the inspection of the main wing spars on AMS-FLIGHT d.o.o. CARAT A powered sailplanes, specifically serial numbers CA005 to CA010 inclusive and CA032. The directive mandates a one-time inspection of the bonding between the upper spar cap and the spar web on both left-hand and right-hand main wing spars to ensure structural integrity. This AD applies to aircraft certified under TCDS number EASA.A.448.

What changed

EASA Airworthiness Directive 2025-0285 introduces a new mandatory inspection requirement for the main wing spars of certain CARAT A powered sailplanes due to identified bonding voids that could compromise wing structural strength. It requires operators to perform a visual inspection and, if discrepancies are found, to carry out repairs following the manufacturer's service bulletin. This AD is a new regulation and does not supersede any previous directives.

Why it matters

This directive is critical for aviation professionals as it addresses a potential structural weakness that could lead to wing failure and loss of the aircraft. Operators and maintenance organizations must ensure compliance to maintain airworthiness and safety. The directive also clarifies compliance timelines and repair procedures, helping maintenance teams plan and execute necessary inspections and corrective actions efficiently.
