12 years on F100 as an LAE, only heard of one other gear related problem, from an engineer colleague on EU jet. Apparently one MLG hung up following a hangar input, engineering advice to crew- "Carry out a heavy landing!". Apparently it worked! I know a lot of LAEs on the F100 and I've heard no bad things about the F100 gear.
Unless you lot aren't booking gear-up landings?!
