Narrative:

Level at 8000' we began to intercept our assigned 148 degree right of seal beach VOR. We had heard the traffic behind our flight to be commuter bab. Flight bab was to maintain visibility contact with our aircraft. While the first officer was flying the aircraft, I monitored the engine INS to set the proper torque calculations. Out of my sight to the left side of our flight, I noticed flight bab fly into our immediate flight path crossing our 10-12 O'clock position spacing of only 200'. Most unprofessional and dangerous! Violation? From our standpoint this seemed to be intentional, and most unprofessional. Had we not joined the arwy, our mdt would have made immediate impact with the commuter light transport. It was a blatant and unprofessional maneuver. Such action should require violation procedures, and possible reprimands. Yes, it involves see and be seen vigilance, but this error was done west/O safety in mind. I certainly hope that our passenger did not feel we were at fault. After calling the FAA and FSDO in la, I feel that our complaint should have been dealt with on a more serious note, although the FAA's help was greatly appreciated.

Title: COMMUTER LTT CUT IN FRONT OF COMMUTER MDT WITHOUT MAINTAINING ADEQUATE VISUAL SEPARATION.

Narrative: LEVEL AT 8000' WE BEGAN TO INTERCEPT OUR ASSIGNED 148 DEG R OF SEAL BEACH VOR. WE HAD HEARD THE TFC BEHIND OUR FLT TO BE COMMUTER BAB. FLT BAB WAS TO MAINTAIN VIS CONTACT WITH OUR ACFT. WHILE THE F/O WAS FLYING THE ACFT, I MONITORED THE ENG INS TO SET THE PROPER TORQUE CALCULATIONS. OUT OF MY SIGHT TO THE LEFT SIDE OF OUR FLT, I NOTICED FLT BAB FLY INTO OUR IMMEDIATE FLT PATH XING OUR 10-12 O'CLOCK POS SPACING OF ONLY 200'. MOST UNPROFESSIONAL AND DANGEROUS! VIOLATION? FROM OUR STANDPOINT THIS SEEMED TO BE INTENTIONAL, AND MOST UNPROFESSIONAL. HAD WE NOT JOINED THE ARWY, OUR MDT WOULD HAVE MADE IMMEDIATE IMPACT WITH THE COMMUTER LTT. IT WAS A BLATANT AND UNPROFESSIONAL MANEUVER. SUCH ACTION SHOULD REQUIRE VIOLATION PROCS, AND POSSIBLE REPRIMANDS. YES, IT INVOLVES SEE AND BE SEEN VIGILANCE, BUT THIS ERROR WAS DONE W/O SAFETY IN MIND. I CERTAINLY HOPE THAT OUR PAX DID NOT FEEL WE WERE AT FAULT. AFTER CALLING THE FAA AND FSDO IN LA, I FEEL THAT OUR COMPLAINT SHOULD HAVE BEEN DEALT WITH ON A MORE SERIOUS NOTE, ALTHOUGH THE FAA'S HELP WAS GREATLY APPRECIATED.
