Narrative:

Taxied out of dtw en route to tpa. 30 mins after start of taxi, load agent advises that the aircraft is 2000 pounds over maximum allowable ramp gross weight (manufacturer's structural limitation!). Flight contacts flight dispatch to request advice. Dispatcher says, stay where you are. Chief dispatcher is consulted. Chief says to taxi back to the gate for off-loading and inspection. Captain states he is unwilling to taxi the aircraft and wants to be towed. Dispatcher says that is the captain's option. Chief dispatcher speaks to flight, captain asks, are you ordering me to taxi this aircraft? Chief dispatcher states, I am authorizing you to taxi back. Captain complies. 1 hour later, captain contacts dispatch, flight is still sitting in the gate. No one has approached the aircraft. No cargo bins have been opened. Meanwhile, maintenance control advises that an overweight landing inspection has been completed on the aircraft! Question: is that inspection legal if the aircraft is still over gross? Chief dispatcher advises management that if someone does not take care of the flight immediately, he will advise the captain to order the aircraft evacuate/evacuationed. This produces the required miracle: 3000 pounds off-loaded from the aircraft. New release issued, new weight tab computed, ATC refiled, flight departed 2:15 late. P.south. Maintenance says the aircraft has a flat strut that has to be pumped up, but it is not related to the over gross taxi. Callback conversation with reporter revealed the following information: reporter said it was the captain who threatened to evacuate/evacuation his passenger if his aircraft wasn't svced soon. He said reason for delay was a manpwr shortage. Ground crew works trip 1 then trip 2. Trip 2 leaves and ground crew goes to trip 3. If trip 2 then returns to the gate, there is no one to handle him. Reporter claims that middle management is to blame. His biggest question: if it is illegal to taxi an aircraft heavier than its maximum taxi weight, isn't it illegal to leave the gate until after the actual aircraft weights are received?
