Narrative:
Go around from missed approach was poorly executed because captain improperly set MCP altitude window and first officer retracted speed brake without command. Together these caused a flap overspd of 10 KTS. After normal landing, flap discrepancy was not entered in the logbook due to late arrival, quick turn, and distraction of snow removal. Because of the rushed ground operations, crew did not debrief the go around sufficiently to discover overspd. The event was more thoroughly discussed at the next station, and the decision was made to enter it in the logbook there. Had we taken the time to thoroughly debrief the event and consider its severity, we would not have departed the first station without entering and properly deferring the discrepancy.

Narrative: GAR FROM MISSED APCH WAS POORLY EXECUTED BECAUSE CAPT IMPROPERLY SET MCP ALT WINDOW AND FO RETRACTED SPD BRAKE WITHOUT COMMAND. TOGETHER THESE CAUSED A FLAP OVERSPD OF 10 KTS. AFTER NORMAL LNDG, FLAP DISCREPANCY WAS NOT ENTERED IN THE LOGBOOK DUE TO LATE ARR, QUICK TURN, AND DISTR OF SNOW REMOVAL. BECAUSE OF THE RUSHED GND OPS, CREW DID NOT DEBRIEF THE GAR SUFFICIENTLY TO DISCOVER OVERSPD. THE EVENT WAS MORE THOROUGHLY DISCUSSED AT THE NEXT STATION, AND THE DECISION WAS MADE TO ENTER IT IN THE LOGBOOK THERE. HAD WE TAKEN THE TIME TO THOROUGHLY DEBRIEF THE EVENT AND CONSIDER ITS SEVERITY, WE WOULD NOT HAVE DEPARTED THE FIRST STATION WITHOUT ENTERING AND PROPERLY DEFERRING THE DISCREPANCY.
