the slip ring once, I decided to do the whole operation again. What I found
was the inner ring brush had a very sticky spring and was sometimes getting
stuck at the mid-way point, thus making intermittent contact with the ring.
(When
I removed the brushes the first time everything appeared fine so I missed
the problem.) It is possible the vibration caused by the landing run and
stopping
the engine might have been enough to cause the brush to contact the inner
ring as all ground feathering tests were fine.
