Narrative:

We departed sna IFR for las. We were on the musel 5 departure, thermal transition. We were on vectors for traffic. Near musel intersection, the controller called out traffic at our 10 O'clock, 5 mi and copilot responded that we had traffic in sight. I looked to see where traffic was and inadvertently pulled back on the yoke. When I looked back at the panel, we were 250 ft high from the assigned altitude of 6000 ft. I started back down to the proper altitude. The controller called and said she had us high from assigned altitude. She asked the jetstream if we were in sight and he said yes. She then said for the jetstream to maintain visual contact. The controller then told us to turn left to a southeast heading and intercept the departure. After a couple of mins, she called and said that she needed us to call the facility when we got on the ground. We did. She said we caused a pilot deviation. She said she needed 1000 ft vertical separation or 3 mi horizontal separation or visual contact. The jetstream had to turn left a few degrees as directed by the controller. We had the jetstream in sight and it was no factor. Supplemental information from acn 341663: the controller stated we were 500 ft off our altitude and lost separation between our 2 aircraft. I never witnessed a deviation any larger than 250 ft nor did our altitude alerter alarms ever activate, indicating the deviation was kept to a minimum.

Title: A CPR HAWKER 800 HAD LTSS WITH AN ACR JETSTREAM. HAWKER ERROR ADMITTED.

Narrative: WE DEPARTED SNA IFR FOR LAS. WE WERE ON THE MUSEL 5 DEP, THERMAL TRANSITION. WE WERE ON VECTORS FOR TFC. NEAR MUSEL INTXN, THE CTLR CALLED OUT TFC AT OUR 10 O'CLOCK, 5 MI AND COPLT RESPONDED THAT WE HAD TFC IN SIGHT. I LOOKED TO SEE WHERE TFC WAS AND INADVERTENTLY PULLED BACK ON THE YOKE. WHEN I LOOKED BACK AT THE PANEL, WE WERE 250 FT HIGH FROM THE ASSIGNED ALT OF 6000 FT. I STARTED BACK DOWN TO THE PROPER ALT. THE CTLR CALLED AND SAID SHE HAD US HIGH FROM ASSIGNED ALT. SHE ASKED THE JETSTREAM IF WE WERE IN SIGHT AND HE SAID YES. SHE THEN SAID FOR THE JETSTREAM TO MAINTAIN VISUAL CONTACT. THE CTLR THEN TOLD US TO TURN L TO A SE HEADING AND INTERCEPT THE DEP. AFTER A COUPLE OF MINS, SHE CALLED AND SAID THAT SHE NEEDED US TO CALL THE FACILITY WHEN WE GOT ON THE GND. WE DID. SHE SAID WE CAUSED A PLTDEV. SHE SAID SHE NEEDED 1000 FT VERT SEPARATION OR 3 MI HORIZ SEPARATION OR VISUAL CONTACT. THE JETSTREAM HAD TO TURN L A FEW DEGS AS DIRECTED BY THE CTLR. WE HAD THE JETSTREAM IN SIGHT AND IT WAS NO FACTOR. SUPPLEMENTAL INFO FROM ACN 341663: THE CTLR STATED WE WERE 500 FT OFF OUR ALT AND LOST SEPARATION BTWN OUR 2 ACFT. I NEVER WITNESSED A DEV ANY LARGER THAN 250 FT NOR DID OUR ALT ALERTER ALARMS EVER ACTIVATE, INDICATING THE DEV WAS KEPT TO A MINIMUM.
