Summary
EASA Airworthiness Directive 2026-0139 is an airworthiness directive addressing inspection requirements for air distribution and air recirculation fans installed on SAAB SF340A and 340B aeroplanes. It specifically targets recirculation fans with part numbers EVCTA465, EVCTA465A, and EVCTA465B due to potential electrical arcing issues. The directive mandates inspections and possible replacement of affected parts to ensure continued airworthiness and safety.
What changed
This new directive introduces mandatory inspections of affected recirculation fans within six months of the effective date and requires replacement of any parts found with discrepancies. It also establishes reporting requirements for inspection results to Saab AB and clarifies installation rules for affected parts. The directive is considered an interim measure pending possible further regulatory action.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk involving electrical arcing that could lead to undetected smoke or fire in the cabin. Operators and maintenance organizations must comply to prevent potential in-flight fire hazards and ensure regulatory compliance. The directive also impacts maintenance planning due to inspection and reporting obligations.
