   To follow up a note I sent earlier,  I found someone who knew more
about gear pins, who said that the airlines consistently remove the gear
pins the first thing after delivery and toss them.  The lock mechanisms are
overcenter backed by beefy springs, so something drastic must have been
done wrong.
