In the mid 1980's a U.S. airliner crashed when the crew forgot to extend takeoff flaps. No t/o config warning was received.
In the NTSB review, it was discovered that the maintenance department thought flight ops did the config warning check, and vice versa.
If you are talking about NorthWest AIrlines 255 then no amount of checking by engineers would have helped as the pilot group were in the habit of pulling the t/o warning config CB to prevent nuisance warnings while taxiing on one engine. Combine that with the failure to complete the checklist and Bob's your uncle. If you're talking about another flight, can you give the number as I am interested in reading about it, thanks.
