Narrative:

This ASRS report is designed to document and alert maintenance about an oversight in the A320 MEL that I recently encountered. The maintenance issue was eventually resolved; but only after much confusion; a near-illegal dispatch; and an attempt to defer the write-up with the incorrect MEL. Once resolved by maintenance; I became aware that this is undoubtedly a common mistake - a misdiagnosed write-up that has the potential to ground the airbus fleet.on walk around inspection; we noticed a 5' section of rubber seal missing on the right wing root between the slat and fuselage. Initial maintenance response was to defer; since they were referencing an MEL for slat seals. Because my co-pilot had seen this issue previously and it had resulted in an illegal dispatch weeks prior; we insisted that the slat seal MEL did not apply to this specific seal; since it is attached to the fuselage and does not travel with the slats. After a maintenance test; this fact was confirmed. Since this seal does not fall within the general MEL outlining deferral of slat seals; a new search was initiated for an MEL addressing this specific seal. It is actually called a fairing installation wing seal. No such MEL exists! My concern is that we have many A320's in the fleet; flying around with a few inches of rubber missing; with the incorrect MEL applied. Maintenance admitted that it was news to them; a common misdiagnosed problem; and that the actual spare replacements seals are limited. They said engineering would have to initiate a new MEL item and I just wanted to do my part in order to insure that the ball is rolling to address this problem.

Title: An A320 Captain reports a Maintenance oversight; where a missing section of rubber seal between the right wing root fuselage body fairing and leading edge slat was deferred under a Slat Seal MEL. Maintenance admitted the damaged seal was a common misdiagnosed problem and spare seals were limited. No MEL exists for the the left or right Fairing Installation Wing Seal.
