Narrative:

The aircraft was dispatched under cdl inboard flap- inboard seal remarks in the flight plan were noted concerning appropriate takeoff adjustments and the flight was conducted routinely; with a flap 40 landing.reviewing the flight plan remarks for the next flight; I noticed a remark about landing weight for a flap 30 landing. Not standard procedure for the runway length at ZZZ. Only then did I realize something was not correct and I consulted the MEL/cdl: operational procedure indicated I was not to use flaps 40 at any time. Dispatch and tech were immediately notified and the aircraft was inspected and released to another crew. Very simple. Consult MEL/cdl for every meled item.
