The flight crew's failure to perform a missed approach upon failing to attain and/or maintain proper course/runway alignment and glidepath on final approach, resulting in a high-sink-rate landing and subsequent separation of a main landing gear wheel from the aircraft.  Factors contributing to the incident included:  low ceiling; the first officer's failure to attain and/or maintain proper course/runway alignment and glidepath on approach; insufficiently defined company procedures for responding to deviations from a stabilized approach profile; inadequate FAA principal operations inspector approval of company operating procedures; and a worn main landing gear wheel retaining nut.
