Cessna; C172F; Cracked Wing Spar; ATA 5711

Replacement of a flap-track assembly revealed a 2-inch crack running through the lower rivet holes in the L/H aft spar (P/N 0523400-50). The submitter speculates a possible cause is from flap deployment at too high of airspeeds. (No corrective actions were included with this discrepancy report. See also the next entry.)
