What to do
Operators of Sonaca S200 and S201 aeroplanes must perform a detailed inspection of the equipment power distribution and main power supply wiring within 25 flight hours after 16 March 2023. If any wiring damage or discrepancies are found, corrective actions must be completed before the next flight, following the procedures in Sonaca Aircraft Service Bulletin SB-SONAIR-S2-033. Alternative methods of compliance may be requested from EASA if properly substantiated.
Summary
EASA Airworthiness Directive 2023-0050 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Sonaca Aircraft S200 and S201 aeroplanes. It mandates inspection and possible repair of the equipment power distribution and main power supply wiring to address potential wiring damage and chafing near the cockpit panel. This directive aims to prevent electrical short circuits and potential electrical fires that could lead to loss of aircraft control.
What changed
EASA Airworthiness Directive 2023-0050 introduces a one-time inspection requirement for the electrical power distribution and main power supply wiring on Sonaca S200 and S201 aeroplanes. It also requires corrective actions if any discrepancies are found during the inspection, based on the instructions provided in Sonaca Aircraft Service Bulletin SB-SONAIR-S2-033. This is a new directive addressing a specific manufacturing and installation deviation.
Why it matters
This directive is critical for operators and maintenance organizations as it addresses a safety risk involving potential electrical fires and loss of power to essential equipment. Compliance ensures continued airworthiness and reduces the risk of in-flight electrical failures that could compromise flight safety. It also provides clear instructions for inspection and repair, facilitating regulatory compliance and maintenance planning.
