Let's assume one takes an 330/340 with a techlog entry like
"Aft Cargo Cmpt smoke warning on Grd. Aft agent discharged."
The warning turned out to be false but agent 1 was used.
One takes the now the MEL and reads
The fire extinguishing may be
inoperative in one or more cargo
compartments provided
associated cargo compartment is
empty or does not contain
inflammable or combustible
materials.
You got it?
