Narrative:

After departing runway 18R tpa tower assigned a heading of 200 degrees with a handoff to tpa departure control on 118.8. Going through 1000 ft MSL, we contacted departure who gave us a right turn to 340 degrees after leaving 3000 ft MSL. At approximately the same time, a system problem developed on the flight engineer's panel that distract both myself and the captain, so much so, that all I heard was the captain readback the turn to 340 degree heading. Because I missed the 3000 ft altitude restriction prior to the 340 degree heading, I began to make the turn at about 1800 ft MSL. Due to the distraction on the flight engineer panel, both the captain and the flight engineer also failed to notice my turning. Departure control queried us as to our heading which at the time was 250 degrees at 2600 ft and also reminded us that we weren't supposed to turn until after 300 ft. I immediately stopped the turn and continued to climb through 3000 ft and then the controller gave us a turn to 350 degrees heading. The flight continued uneventfully.

Title: FO OF ACR LGT ACFT TURNED TOO EARLY DURING DEP PRIOR TO REACHING ASSIGNED ALT. HDG TRACK DEV.

Narrative: AFTER DEPARTING RWY 18R TPA TWR ASSIGNED A HDG OF 200 DEGS WITH A HDOF TO TPA DEP CTL ON 118.8. GOING THROUGH 1000 FT MSL, WE CONTACTED DEP WHO GAVE US A R TURN TO 340 DEGS AFTER LEAVING 3000 FT MSL. AT APPROX THE SAME TIME, A SYS PROBLEM DEVELOPED ON THE FLT ENGINEER'S PANEL THAT DISTRACT BOTH MYSELF AND THE CAPT, SO MUCH SO, THAT ALL I HEARD WAS THE CAPT READBACK THE TURN TO 340 DEG HDG. BECAUSE I MISSED THE 3000 FT ALT RESTRICTION PRIOR TO THE 340 DEG HDG, I BEGAN TO MAKE THE TURN AT ABOUT 1800 FT MSL. DUE TO THE DISTR ON THE FLT ENGINEER PANEL, BOTH THE CAPT AND THE FLT ENGINEER ALSO FAILED TO NOTICE MY TURNING. DEP CTL QUERIED US AS TO OUR HDG WHICH AT THE TIME WAS 250 DEGS AT 2600 FT AND ALSO REMINDED US THAT WE WEREN'T SUPPOSED TO TURN UNTIL AFTER 300 FT. I IMMEDIATELY STOPPED THE TURN AND CONTINUED TO CLB THROUGH 3000 FT AND THEN THE CTLR GAVE US A TURN TO 350 DEGS HDG. THE FLT CONTINUED UNEVENTFULLY.
