The mass excess of the proton-rich nucleus Al-23 has been measured with the JYFLTRAP Penning trap setup. As a result of our experiment we obtain a mass excess of 6748.07(34) keV, and by combining the value to existing experimental data we have tested the validity of the isobaric multiplet mass equation (IMME) for the T = 3/2 quartet in the A = 23 isobar. The fit to the IMME results in a vanishing cubic term equivalent to zero with high precision [0.22(42) keV].
