Narrative:

Flight pairing I was flying included a scheduled aircraft change. Aircraft that I changed to, had 4 MEL's. 1 MEL was for the standby hydraulic system quantity light inoperative. According to our company MEL, maintenance as denoted by an (M) was to visually check the hydraulic fluid quantity prior to each departure. This was accomplished in phx prior to my arrival at aircraft. An entry was made in the logbook saying that fluid was added to the system. Prior to departure from phx, I notified dispatch to arrange for contract maintenance to meet aircraft upon arrival in den to visually inspect hydraulic system quantity. Flight was late arriving den because of en route holding due to adverse WX (snow and ice). While on the ground in den preparing for departure I inadvertently forgot to have contract maintenance check hydraulic system quantity. My copilot and company dispatch and maintenance also forgot. I visually checked quantity while accomplishing walk-around inspection at den. Takeoff checklist also requires inspection of hydraulic system quantity gauge. Both checks showed that quantity was ok. I flew aircraft back to phx without incident other than possible missing a logbook entry. Contributing factors: fourth day of consecutive flying. Duty time approaching 12 hours. Adverse WX leading to en route holding, aircraft de-ice while on ground at den (first time for me this winter season). Performance considerations as aircraft had an intermix of engines (minus 15 and minus 9A). Also possible over gross weight for runway conditions.

Title: FLC FAILED TO HAVE REQUIRED MAINT INSPECTION FOR AN MEL ITEM PRIOR TO DEP.

Narrative: FLT PAIRING I WAS FLYING INCLUDED A SCHEDULED ACFT CHANGE. ACFT THAT I CHANGED TO, HAD 4 MEL'S. 1 MEL WAS FOR THE STANDBY HYD SYS QUANTITY LIGHT INOP. ACCORDING TO OUR COMPANY MEL, MAINT AS DENOTED BY AN (M) WAS TO VISUALLY CHK THE HYD FLUID QUANTITY PRIOR TO EACH DEP. THIS WAS ACCOMPLISHED IN PHX PRIOR TO MY ARR AT ACFT. AN ENTRY WAS MADE IN THE LOGBOOK SAYING THAT FLUID WAS ADDED TO THE SYS. PRIOR TO DEP FROM PHX, I NOTIFIED DISPATCH TO ARRANGE FOR CONTRACT MAINT TO MEET ACFT UPON ARR IN DEN TO VISUALLY INSPECT HYD SYS QUANTITY. FLT WAS LATE ARRIVING DEN BECAUSE OF ENRTE HOLDING DUE TO ADVERSE WX (SNOW AND ICE). WHILE ON THE GND IN DEN PREPARING FOR DEP I INADVERTENTLY FORGOT TO HAVE CONTRACT MAINT CHK HYD SYS QUANTITY. MY COPLT AND COMPANY DISPATCH AND MAINT ALSO FORGOT. I VISUALLY CHKED QUANTITY WHILE ACCOMPLISHING WALK-AROUND INSPECTION AT DEN. TKOF CHKLIST ALSO REQUIRES INSPECTION OF HYD SYS QUANTITY GAUGE. BOTH CHKS SHOWED THAT QUANTITY WAS OK. I FLEW ACFT BACK TO PHX WITHOUT INCIDENT OTHER THAN POSSIBLE MISSING A LOGBOOK ENTRY. CONTRIBUTING FACTORS: FOURTH DAY OF CONSECUTIVE FLYING. DUTY TIME APCHING 12 HRS. ADVERSE WX LEADING TO ENRTE HOLDING, ACFT DE-ICE WHILE ON GND AT DEN (FIRST TIME FOR ME THIS WINTER SEASON). PERFORMANCE CONSIDERATIONS AS ACFT HAD AN INTERMIX OF ENGS (MINUS 15 AND MINUS 9A). ALSO POSSIBLE OVER GROSS WT FOR RWY CONDITIONS.
