Remember, first define the problem, then solve it.

so i would suggest u to be careful in assessing the damage area. use ur own senses and instinct in addition to NDI. probably hardness test was carried out on point with a space of 1 inches (but it has been sme time ago, so i m not that sure)
any fire extinguisher used? it may make the case bad....
all this applies to conventionally riveted structures.....
I would suggest its a cut and repair case provided no extinguisher was used or it caused no effect.....

The damaged area cover 5 frame bay and 8 stringer , all deformed parts identified , the conductivity test already done and revealed that 4 frame end 2 stringer must be replaced , for the skin the conductivity test ok but Airbus request a hardness test , whil performing the skin hardness test i had doupt about the values given by roquell hardness test , the measured values on internal surfaces gives 130 (roquell) the external surface (70 roquell) , my quation what is the hardness of the 2024T42 material , and second quation for the external and internal surface thy have the same hardeness values or diferent values.
Thank you friends.

i'm sure that a quick google search will find hardness of Al.
but why ask us, when you're talking to the OEM ?
