During service check general inspection of the cabin observed seat back tray tables installed in aisle 14 a-b-c and aisle 14 d-e-f. Both aisles are emergency exit aisles. The seats have the correct tables installed in the arm rest; and incorrectly installed tray tables in the seat back obstructing emergency egress from the aircraft.
Maintenance Technician reported discovering seat trays had been erroneously installed in seat backs at exit rows that would potentially obstruct emergency egress.
