Isn't restarting an engine after suspected foreign object ingestion a bad idea?
In general, I'd agree. The one I mentioned was a B747F operated by a well known Oriental outfit and we think the fan was damaged on departure from Dubai. The fan damage was in line with the bypass duct and the dimensions of distortion were just within the permitted limit subject to a vibration check in all ranges.
Unfortunately, the vib was just outside limits so we couldn't operate. Don't think we had anything perishable on board.
