I've only time to look at 14 CFR 61.51, so my comments are based only on this.
First, I do not see in this section "intent" as being loggable.
Second, Sec 61.51 (b) talks about "logbook entries" like this:
(b) Logbook entries. For the purposes of meeting the requirements of paragraph
(a) of this section, each person must enter the following information
for each flight or lesson logged:
(1) General—
(i) Date.
(ii) Total flight time or lesson time.
(iii) Location where the aircraft departed and arrived, or for lessons in a flight simulator or flight training device, the location where the lesson occurred.
The conjunctive here implies the aircraft must have taken flight in order to be loggable.
Third, this section goes on to talk about solo flight time and PIC flight time. It does not appear to talk about non-flight time.
The original poster is still in the learning stages, and I well appreciate that any flight time is expensive to get. I think that if you, unlike me, have plans to work for an airline, you will need thousands of hours. And by the time you get those hours and find yourself sitting in an interview, this maintenance episode could be considered de minimis. You will have to decide for yourself whether logging this time is legally defensible if ever you get questioned on it.
Finally, I'd go with whatever TonyC says. :)
