Our club in the UK has two DG1000s with the two wheel
tail dragger configuration. We have had numerous undercarriage
collapses on landing, but as far as I know no unwanted
extentions in flight.

Our club has #23 and has put *a lot* of hours and landings on it in the
last few years. No retract problems so far on landing.

My completely uninformed guess is that those unexpectedly retracted
gears were just not locked. I *almost* landed with an extended but
unlocked gear myself, but recognized the situation just in time. It
takes a lot of force to correctly lock the gear. Start the process early
and always visually double check the handle position.
