wow so if you had 100 hours... now you have 100.3
um no. i wouldnt log it.
If you are looking for the legal dorky answer, I believe the FAR's say any event in which the pilot had "intent" to fly, not if you actually flew or not. Like if you taxi'ed any aircraft from one ramp to other otherside of an airport and it took 30 minutes... no intent for flight... cant log it. Looks like in your case.. you could log it if you really wanted to.
I had a few of these happen when I was a flight instructor... never logged them... i probably lost out on a whole combined hour of flight time. Just terrible!
