Aircraft was preflted in accordance with company procedures and departed fort lauderdale. Flight was routine to atl, GA. Aircraft was parked at concourse gate. We departed medium large transport to connect with our next flight to dtw. After a right.O.north. In dtw the captain had a message to call (sic) at telephone no XXXX. The captain was informed that one of the main gears had collapsed on large transport while parked at the gate. As flight engineer on flight, I would like to state that no discrepancies were discovered on preflight in fll, and the flight to atl was routine. The aircraft was operated completely in compliance with company procedures, manuals, and checklist. The landing in atl was text book with a smooth T/D. At no time while I was on large transport was there any indication of a problem with any of the landing gear. Callback conversation with reporter revealed the following information: followup revealed the main trunnion failed right at the attach point. It failed after fueling had started for the next flight. G meter revealed no hard lndgs in the last six which was all it contained. This was one of the newer lgts this airline has, so is not thought that age was a factor. At this point trunnion is being checked for metal fatigue. One thought is it was somehow defective casting. FAA has investigated but is taking no action.
