As you point out this is the usual reason for uncommanded gear retraction
events. After a bad bounce the gear is pulling itself downwards due to the
-ve G, this straightens out the over centre mechanism and can flick it past
the in line position if there is any looseness in the mechanism, the three
AN4 bolts holding the handle to the LG 08 (left). If the wheel touches the
ground at this point in the sequence all the load will be on the retract
lever and locking slot instead of the stops, then the lever will let go.
