Wrong gear pin
Thx for the info DBate. Once again use of wrong equipment, pressure to do a quick job and the whole thing goes to the dogs. I was involved in the follow up to a similar situation three or four years ago. The lads were working a landing gear problem in TLV, and it was hurry, hurry. No correct nose gear pin to hand, but there was a DC-10 alternate centre gear pin in a vehicle. It held for a couple of selections and then shook itself out. You know the result.
Perhaps one day we will learn and act on the old adage 'Less haste - more speed.'
