fly it to his shop on 9-30-04 to check it out in Owosso,
[Michigan].
I decided to take it over [at] 7 PM on the 29th of [September]. I had
done (1) one takeoff [and] landing to [check] it out. The second
takeoff North almost [zero] wind, [the engine] cut out, no power [and]
was about only 60 [feet] up ... . It struck a Consumers Power cable with
the [right] wheel, not really knowing what may be damaged, I put
it down in a field [and] got it stopped, and shut it down [and]
walked home.
