Narrative:
During departure lost 'B' hydraulic. Ran checklist. Returned normally to airport. On T/D checklist called for second officer to open 'brake interconnect.' he opened 'hydraulic interconnect.' resulted in large loss in braking capability at a greatly increased T/D speed. Checklist and nomenclature should change name of components to provide greater distinction.
Original NASA ASRS Text
Title: ACR LGT LOST 'B' HYDRAULIC AFTER TKOF AND ON RETURN SO OPENED THE WRONG HYDRAULIC INTERCONNECT, RESULTING IN A LONG LNDG ROLL.
Narrative: DURING DEP LOST 'B' HYD. RAN CHKLIST. RETURNED NORMALLY TO ARPT. ON T/D CHKLIST CALLED FOR S/O TO OPEN 'BRAKE INTERCONNECT.' HE OPENED 'HYD INTERCONNECT.' RESULTED IN LARGE LOSS IN BRAKING CAPABILITY AT A GREATLY INCREASED T/D SPD. CHKLIST AND NOMENCLATURE SHOULD CHANGE NAME OF COMPONENTS TO PROVIDE GREATER DISTINCTION.
