Narrative:

Chain of events: after takeoff from lax on initial climb the GPWS pull up warning activated, the master caution light illuminated, the flight director pitch bar pitched to -5 degrees (down), and the automatic throttles disengaged. Conditions were IMC. I flew the aircraft maintaining a normal climb profile and clean up while the captain and second officer handled the electrical problem which was a failure of phase a #1 AC bus circuit breaker. The GPWS came on again and the captain inhibited it, then once more and the captain inhibited it for the final time. By this time we were VMC and cleared direct lax VOR to cross lax VOR at 10000'. After the turn was completed and before reaching the VOR the captain advised ATC (lax departure control) that we would not be able to make the 10000' crossing. ATC acknowledged and instructed us to cross 7 DME east of the VOR at 13000'. Approximately 1 min later and before reaching 7 DME east the captain advised ATC we could not make that crossing. ATC acknowledged and switched us to ZLA. Shortly after this the captain and F/east solved the electrical problem and all systems returned to normal. Human performance considerations: I feel that I was distracted by the caution lights, GPWS, flight director failure, automatic throttle failure and electrical problem just enough so that I did not plan the turn or calculate the aircraft climb performance as quickly as I normally would have. More concentration and pre-departure planning may have prevented this.

Title: ALT CROSSING RESTRICTIONS NOT MET ON SID ATC CLRNC.

Narrative: CHAIN OF EVENTS: AFTER TKOF FROM LAX ON INITIAL CLB THE GPWS PULL UP WARNING ACTIVATED, THE MASTER CAUTION LIGHT ILLUMINATED, THE FLT DIRECTOR PITCH BAR PITCHED TO -5 DEGS (DOWN), AND THE AUTO THROTTLES DISENGAGED. CONDITIONS WERE IMC. I FLEW THE ACFT MAINTAINING A NORMAL CLB PROFILE AND CLEAN UP WHILE THE CAPT AND S/O HANDLED THE ELECTRICAL PROB WHICH WAS A FAILURE OF PHASE A #1 AC BUS CB. THE GPWS CAME ON AGAIN AND THE CAPT INHIBITED IT, THEN ONCE MORE AND THE CAPT INHIBITED IT FOR THE FINAL TIME. BY THIS TIME WE WERE VMC AND CLRED DIRECT LAX VOR TO CROSS LAX VOR AT 10000'. AFTER THE TURN WAS COMPLETED AND BEFORE REACHING THE VOR THE CAPT ADVISED ATC (LAX DEP CTL) THAT WE WOULD NOT BE ABLE TO MAKE THE 10000' XING. ATC ACKNOWLEDGED AND INSTRUCTED US TO CROSS 7 DME E OF THE VOR AT 13000'. APPROX 1 MIN LATER AND BEFORE REACHING 7 DME E THE CAPT ADVISED ATC WE COULD NOT MAKE THAT XING. ATC ACKNOWLEDGED AND SWITCHED US TO ZLA. SHORTLY AFTER THIS THE CAPT AND F/E SOLVED THE ELECTRICAL PROB AND ALL SYSTEMS RETURNED TO NORMAL. HUMAN PERFORMANCE CONSIDERATIONS: I FEEL THAT I WAS DISTRACTED BY THE CAUTION LIGHTS, GPWS, FLT DIRECTOR FAILURE, AUTO THROTTLE FAILURE AND ELECTRICAL PROB JUST ENOUGH SO THAT I DID NOT PLAN THE TURN OR CALCULATE THE ACFT CLB PERFORMANCE AS QUICKLY AS I NORMALLY WOULD HAVE. MORE CONCENTRATION AND PRE-DEP PLANNING MAY HAVE PREVENTED THIS.
