EY-AA set itheir own MCT's. MCT is simply EY's willingness to accept the risk of a misconnect and it is not willing to do so here.
[IATA] Resolution 765 indicates that airlines are responsible for their own bilateral agreements with other airlines or railways for shorter or longer intermodal MCT intervals in those cases where particular circumstances of their special arrangements/situations make this possible or necessary.
EY/AA's decision to adhere to the I-D MCT for pre-clearance flights is the subject of several other complaints here on FT and it appears that it is not an error, but rather an intentional policy.
If there is any way not to check a bag, it is more than likely that AA will rebook OP onto the earlier flight if he makes it to the departure gate in a timely manner. If not a flexible ticket permitting a fee-free change, AA will almost certainly rebook in any event even if this is not within the SDC / SDSB policy.
If OP must check a bag, this is more difficult as AA will not likely locate and pull a bag with such a short time between flights and this is a voluntary change which will likely prevent most AA agents from being able to make a change with a checked bag in the system.
