Narrative:

I was taxiing after a landing on the grass parallel to runway 7 when my 1950 piper pacer became mired in a patch of non-observable soft ground and the aircraft quickly flipped over without warning. I was transitioning off the runway at the time of the incident and was travelling less than 15 miles per hour. This landing area is used regularly by light aircraft such as mine and an active glider club is located in front of the runway.
