Requires a one-time inspection/test of the number 2 and 3 feeder fuel tanks and, depending on findings, replacement. Prompted by an occurrence where an EC175B experienced an uncommanded engine shutdown on the ground with both fuel booster pumps off. An investigation determined that this event was caused by a defective feeder tank connection, allowing air ingestion into the fuel line when the booster pumps are off.
