76P had an engine chip warning and landed on the Auk - sorry to disappoint but it didn't have an engine failure!
It took a long time to fix because of the difficulty in getting an engineer out to the installation - I believe Bond Jigsaw helped out - then it seems the battery was left on too long and went flat during the start, and the offshore ground power was unserviceable. Had to send a ground power unit by boat from the Fulmar etc etc. The "Chip" was a tiny sliver of course....
