Many moons ago, this happened on a flight I was on. YEG to YLW on a Time Air Dash 7. They had to hand crank the gear, spent a while burning fuel then made a very gentle landing. The right main gear only partially came down, and was hand cranked to the locked position. Pilot did a great job of landing on the left main, then nose gear, the right gear when the right wing stopped flying. Only time I have had to adopt the brace position, all was good with no problems at all.
