Airbus aircraft had CF6-80A3 engines and I referenced MEL 36-11-03 that referenced CF6-90C2 engines for High Pressure (HP) Valve inoperative (inop). If the aircraft had CF6-80C2 engines; the MEL would apply. However; it did not have CF6-80C2 engines; which would not require a lock-out of the Thrust Reverser (T/R). Because of this error; the Thrust Reverser was locked-out when it was not required; nor documented as such. Pilot tried to use the T/R when landing and the Number 2 T/R was locked-out with no documentation. When I looked up the Engine type for this aircraft under Aircraft Component Control; I [had] looked at the engine type incorrectly by two letters; so an error was made. [Recommend] slow down and double check the documents.
A Line Mechanic reports an incorrect MEL had been applied to an Airbus aircraft with CF6-80A3 engines. Number Two Engine Thrust Reverser (T/R) had been locked out when it was not required and was not documented. Pilot had tried to use the T/R on landing.
