Background:	Initial investigation of a recent C-212 Maritime Patrol aircraft accident has revealed cracks in the centre wing lower skin at STA Y=1030. The aircraft had accumulated 17,000 flight hours and 7,300 flight cycles. Fatigue cracking is suspected to be the cause.The suspect element is identified in document C-212-PV-02-SID as a Principal Structural Element with No. 57.212.06 and an inspection threshold of 20,000 landings.
