Narrative:

On final to runway 30R, with gear down and flaps set to 25 degrees, we had a complete loss of our hydraulic 'a' system. So and I completed the appropriate checklist and landed uneventfully. Later, on the layover we realized we landed with the incorrect flap setting called for in the procedures. Should have been 15 degrees, we used 30 degrees. When practicing this procedure in training, we always start off clean, flaps 0 degrees. We then dirtied up the airplane using the checklist. Because we were already beyond flaps 15 degrees, the checklist sort of led us past that step the way we read it (incorrectly). We had already completed the approach check before anything happened and we passed the page that continues after approach check. (The book says 'accomplish the approach check if not previously accomplished').

Title: B727 CREW HAD A SYS HYD FAILURE ON APCH AT MSP.

Narrative: ON FINAL TO RWY 30R, WITH GEAR DOWN AND FLAPS SET TO 25 DEGS, WE HAD A COMPLETE LOSS OF OUR HYD 'A' SYS. SO AND I COMPLETED THE APPROPRIATE CHKLIST AND LANDED UNEVENTFULLY. LATER, ON THE LAYOVER WE REALIZED WE LANDED WITH THE INCORRECT FLAP SETTING CALLED FOR IN THE PROCS. SHOULD HAVE BEEN 15 DEGS, WE USED 30 DEGS. WHEN PRACTICING THIS PROC IN TRAINING, WE ALWAYS START OFF CLEAN, FLAPS 0 DEGS. WE THEN DIRTIED UP THE AIRPLANE USING THE CHKLIST. BECAUSE WE WERE ALREADY BEYOND FLAPS 15 DEGS, THE CHKLIST SORT OF LED US PAST THAT STEP THE WAY WE READ IT (INCORRECTLY). WE HAD ALREADY COMPLETED THE APCH CHK BEFORE ANYTHING HAPPENED AND WE PASSED THE PAGE THAT CONTINUES AFTER APCH CHK. (THE BOOK SAYS 'ACCOMPLISH THE APCH CHK IF NOT PREVIOUSLY ACCOMPLISHED').
