Boeing rules on resetting CB's

1. No procedure in current-production airplanes calls for the pulling (and resetting) of any CB's

2. Flight Crew reset of tripped fuel pump control circuit breakers in flight is prohibited. Reset of any other tripped circuit breaker is not recommended unless in the judgment of the Captain, the situation resulting from the circuit breaker trip has a significant adverse effect on safety. These other tripped circuit breakers may be reset once, after a short cooling period (approximately 2 minutes).

Very precise and sane. One cannot start a fire on a plane by resetting a tripped circuit breaker once. One can only do it by burning out wiring by resetting repeatedly/holding in a CB that's being tripped by a shorted out component.

Now the amusing part is that the crew already got a medal for bravery, so it will be a political problem if they are found to have overlooked this little thing.

Don't you just love it when the politicians get involved in these things even before the preliminary report is issued.
