Narrative:

Near midair collision while cruising at 10,000', 250 KTS, heading approximately 150 degree. Received clearance from ocean approach to proceed direct pvd and descend to 7000', requiring a turn to a heading of approximately 060 degree. Approach immediately followed with traffic at 12 O'clock, 1 mi, 10,000'. F/east pointed to traffic right to left on a close perpendicular collision course. Captain maneuvered aircraft abruptly up and to the right to pass up and behind aircraft. Aircraft passed approximately 100-200' vertical and approximately 300' horizontal. F/a fell to the floor in aft galley, no apparent injury to crew or passenger.

Title: ACR CAME IN CLOSE PROX TO AN SMT DURING DESCENT.

Narrative: NEAR MIDAIR COLLISION WHILE CRUISING AT 10,000', 250 KTS, HDG APPROX 150 DEG. RECEIVED CLRNC FROM OCEAN APCH TO PROCEED DIRECT PVD AND DSND TO 7000', REQUIRING A TURN TO A HDG OF APPROX 060 DEG. APCH IMMEDIATELY FOLLOWED WITH TFC AT 12 O'CLOCK, 1 MI, 10,000'. F/E POINTED TO TFC RIGHT TO LEFT ON A CLOSE PERPENDICULAR COLLISION COURSE. CAPT MANEUVERED ACFT ABRUPTLY UP AND TO THE RIGHT TO PASS UP AND BEHIND ACFT. ACFT PASSED APPROX 100-200' VERTICAL AND APPROX 300' HORIZONTAL. F/A FELL TO THE FLOOR IN AFT GALLEY, NO APPARENT INJURY TO CREW OR PAX.
