What to do
Operators must perform a one-time inspection of the equipment power distribution and main power supply wiring behind the instrument panel within 25 flight hours after 16 March 2023, and an additional inspection behind both the instrument and circuit board panels within 25 flight hours after 7 July 2023. Any discrepancies found must be corrected before the next flight following the instructions in Sonaca Aircraft Service Bulletin SB-SONAIR-S2-033 Revision C. Previous inspections done per earlier revisions of the service bulletin are acceptable for compliance.
Summary
EASA Airworthiness Directive 2023-0126 is an official regulatory document addressing the inspection of electrical power distribution and main power supply wiring on Sonaca S200 and S201 aeroplanes. It mandates inspections behind the instrument and circuit board panels in the cockpit to detect wiring damage or chafing that could lead to electrical failures or fire. This directive applies to all serial numbers of the affected aircraft models.
What changed
This directive supersedes EASA AD 2023-0050 and expands the inspection areas to include wiring behind both the instrument panel and the circuit board panel in the cockpit. It introduces additional inspection points and corrective actions based on new findings of wiring damage, including the main fuel pump wiring, discovered during unscheduled maintenance. The directive retains previous inspection requirements while adding new ones to address the broader scope of potential wiring issues.
Why it matters
This directive is critical for aviation professionals because undetected wiring damage can cause loss of power to essential equipment, electrical short circuits, or even cockpit fires, which may result in loss of aircraft control. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and safety. Timely inspections and repairs help prevent in-service failures and enhance operational reliability of Sonaca S2 aeroplanes.
