Narrative:

Air carrier X was cleared to takeoff on runway 16L sea, with the mountain 5 departure to 9000 ft. After takeoff, during climb out, the controller amended the altitude to 6000 ft, at about the time the SID specified a left turn to a 070 degree heading. The controller then directed a climb to 9000 ft. Passing 6000 ft, the controller directed us to maintain 6000 ft and queried us regarding the turn. Confusion arose due to multiple altitude changes causing us to turn late. First officer was flying. It was his first leg after IOE. The SID was not in the FMS database, crew entered it manually. Supplemental information from acn 566168: the crew was distraction by numerous altitude changes and subsequently the left turn to 070 degrees was initiated late. Contributing factors: new first officer (PF) and unwarranted complacency by captain considering mountain 5 departure not in FMS database.

AFTER TKOF, DURING CLBOUT, THE CTLR AMENDED THE ALT TO 6000 FT, AT ABOUT THE TIME THE SID SPECIFIED A L TURN TO A 070 DEG HDG. THE CTLR THEN DIRECTED A CLB TO 9000 FT. PASSING 6000 FT, THE CTLR DIRECTED US TO MAINTAIN 6000 FT AND QUERIED US REGARDING THE TURN. CONFUSION AROSE DUE TO MULTIPLE ALT CHANGES CAUSING US TO TURN LATE. FO WAS FLYING. IT WAS HIS FIRST LEG AFTER IOE. THE SID WAS NOT IN THE FMS DATABASE, CREW ENTERED IT MANUALLY. SUPPLEMENTAL INFO FROM ACN 566168: THE CREW WAS DISTR BY NUMEROUS ALT CHANGES AND SUBSEQUENTLY THE L TURN TO 070 DEGS WAS INITIATED LATE.
