Narrative:

Dispatched with a follow-up requirement on the MEL concerning yellow hydraulic reservoir pressure. Logbook notation was made by myself ensuring maintenance's compliance. After further discussion with first officer en route to ZZZ it was determined from the wording in the MEL, maintenance personnel should have entered the notation themselves. On subsequent leg, we ensured maintenance personnel made the logbook notation. Problem arose because of debatable language in the 'operations' section of the MEL, which I misinterpreted. No corrective action was required on the part of maintenance, only a reading of a gauge, of which procedure I noted. However, after a further review and discussion, we realized the making of the notation was under the 'maintenance' section of MEL. The 'operations' section had the 'ensuring notation was made' -- not 'ensuring of procedure.' to prevent reoccurrence, a closer examination of both parts, maintenance as well as operations, of the MEL should be studied.

Title: A319 CREW IMPROPERLY SUPPLIED A REQUIRED HYD PRESSURE READING THAT WAS TO BE SUPPLIED BY MAINT PERSONNEL FOR A MEL DEFERRAL.

Narrative: DISPATCHED WITH A FOLLOW-UP REQUIREMENT ON THE MEL CONCERNING YELLOW HYD RESERVOIR PRESSURE. LOGBOOK NOTATION WAS MADE BY MYSELF ENSURING MAINT'S COMPLIANCE. AFTER FURTHER DISCUSSION WITH FO ENRTE TO ZZZ IT WAS DETERMINED FROM THE WORDING IN THE MEL, MAINT PERSONNEL SHOULD HAVE ENTERED THE NOTATION THEMSELVES. ON SUBSEQUENT LEG, WE ENSURED MAINT PERSONNEL MADE THE LOGBOOK NOTATION. PROB AROSE BECAUSE OF DEBATABLE LANGUAGE IN THE 'OPS' SECTION OF THE MEL, WHICH I MISINTERPRETED. NO CORRECTIVE ACTION WAS REQUIRED ON THE PART OF MAINT, ONLY A READING OF A GAUGE, OF WHICH PROC I NOTED. HOWEVER, AFTER A FURTHER REVIEW AND DISCUSSION, WE REALIZED THE MAKING OF THE NOTATION WAS UNDER THE 'MAINT' SECTION OF MEL. THE 'OPS' SECTION HAD THE 'ENSURING NOTATION WAS MADE' -- NOT 'ENSURING OF PROC.' TO PREVENT REOCCURRENCE, A CLOSER EXAMINATION OF BOTH PARTS, MAINT AS WELL AS OPS, OF THE MEL SHOULD BE STUDIED.
