Let me guess- the circlip that holds the door hydraulic ram together- happened many times.
The most creative solution to the problem was a chap in the Pilbara many years ago who had a load of black fellas on. Got one of them to hang out the door and pull the main strut into locked position with a cargo net. landed safely.
Don't worry CASA you sh*tcanned him years ago. The "three scrooges" was his name............
