EASA AD 2025-0154R1
Aircraft Flight Manual - Limitation / Wings — Front and Rear Spar — Inspections
Summary
The document titled Aircraft Flight Manual - Limitation / Wings — Front and Rear Spar — Inspections is an EASA Airworthiness Directive 2025-0154R1 issued on 7 August 2025. It applies to LAVIA ARGENTINA S.A. PA-25, PA-25-235, and PA-25-260 aeroplanes and mandates inspections of specific front and rear wing spars identified by part numbers. The directive addresses corrosion and crack findings in wing spars and related fittings to ensure continued airworthiness.
What Changed
EASA AD 2025-0154R1 revises the original AD 2025-0154 by clarifying the definition of Group 1 spars and correcting erroneous references regarding spar installation. It introduces differentiated inspection regimes and operational limitations based on spar age and usage, particularly for agricultural spray operations. The revision also supersedes the adoption of the related ANAC Argentina AD 2024-05-01 R1.
Why It Matters
This directive is critical for aviation professionals because it ensures the structural integrity of wing spars on affected aircraft, preventing potential failures due to corrosion, cracks, or unauthorized repairs. Operators and maintenance organizations must comply to maintain aircraft airworthiness and avoid grounding. The AD also impacts maintenance planning by requiring specific inspection intervals and approved repair procedures.
What To Do
Operators must perform initial and recurring inspections of affected front and rear spars within specified flight hour or calendar intervals starting 1 August 2025. Group 1 and Group 2 spars have distinct inspection and non-destructive testing requirements, with corrective actions mandated if discrepancies are found. Additionally, affected aircraft must update their Aircraft Flight Manuals and install specified placards where applicable to reflect operational limitations.
