Narrative:

Copilot copied ATC clearance prior to takeoff from O66 to sna. ATC assigned the usual heading of 020 degrees after takeoff (runway heading). Copilot misheard 020 degrees as 200 degrees. Copilot read back 200 heading to ATC and ATC failed to correct him to 020 degrees. Captain was not privy to this conversation as captain was performing other preflight duties. Copilot set 200 degrees in heading window and the captain failed to notice 200 degrees instead of 020 degrees. After takeoff, copilot began turning from runway heading of 020 degrees toward 200 degrees. When finishing after takeoff checklist, captain noticed this unusual right turn. Captain queried copilot. Copilot appeared confused, so captain queried radar ATC. ATC confirmed assigned heading of 020 degrees. Captain and copilot returned to 020 degrees. The problem was high terrain toward 200 degree direction. To resolve future problems, captain will confirm ATC clrncs with copilot before takeoff.

Title: AN INCORRECT HDG TOWARD HIGH TERRAIN FLOWN AFTER TKOF BY AN ACR.

Narrative: COPLT COPIED ATC CLRNC PRIOR TO TKOF FROM O66 TO SNA. ATC ASSIGNED THE USUAL HDG OF 020 DEGS AFTER TKOF (RWY HDG). COPLT MISHEARD 020 DEGS AS 200 DEGS. COPLT READ BACK 200 HDG TO ATC AND ATC FAILED TO CORRECT HIM TO 020 DEGS. CAPT WAS NOT PRIVY TO THIS CONVERSATION AS CAPT WAS PERFORMING OTHER PREFLT DUTIES. COPLT SET 200 DEGS IN HDG WINDOW AND THE CAPT FAILED TO NOTICE 200 DEGS INSTEAD OF 020 DEGS. AFTER TKOF, COPLT BEGAN TURNING FROM RWY HDG OF 020 DEGS TOWARD 200 DEGS. WHEN FINISHING AFTER TKOF CHKLIST, CAPT NOTICED THIS UNUSUAL R TURN. CAPT QUERIED COPLT. COPLT APPEARED CONFUSED, SO CAPT QUERIED RADAR ATC. ATC CONFIRMED ASSIGNED HDG OF 020 DEGS. CAPT AND COPLT RETURNED TO 020 DEGS. THE PROB WAS HIGH TERRAIN TOWARD 200 DEG DIRECTION. TO RESOLVE FUTURE PROBS, CAPT WILL CONFIRM ATC CLRNCS WITH COPLT BEFORE TKOF.
