Narrative:
While performing walkaround on aircraft, found 2 each 1/2-3/4 inch cracks on aircraft right 3 frames behind radome, approximately 9 O'clock position on fuselage skin (non pressurized). Being at departure time, I notified maintenance control of situation and suggested we continue on to our main base (next leg) as no safety risk was there (non pressurized) to which all were in agreement. At the maintenance base the aircraft was repaired. Basically, my judgement should have been to ground the plane, or possibly find limits, etc. Being in an airline environment it is 'go, go, go.'
