What's in your toolkit?
After having been forcibly reminded today at Carlisle that there's no such thing as an Aviation RAC (thanks Jason for a very welcome hand to change my duff plug) I was thinking of establishing a small spares box for the aerial conveyance.
It's a Piper Cherokee so as well as a spare plug, credit card, driving licence and lots of money what else would Prooners recommend I carry for those "tech" moments that seem to strike on Sunday and Bank Holidays?
