Hmm. If the possibility of a gear pin wrongly fitted was known about and indeed publicised, there’s not much of an excuse for still fitting the pin in the wrong hole? Surely if you are then going to run some checks where the correct fitting of that pin is all that stops the leg retracting when commanded to do so, you’re going to go back outside and check all 3 are correctly fitted!
Irrespective of the various holes present, doesn't simple physics give you a big clue as to where a locking pin should be fitted to do its job?
