Controller at vgt tower departs aircraft #1 VFR to the northwest and 3 mins later departs aircraft #2 IFR to the southeast. The courses of the aircraft converged south of the airport and the reporter claims an near midair collision occurred.

Narrative:

Aircraft #1, a C402, departed vgt tower on a coded departure route at XA45Z to the grand canyon. Hawker sidley, aircraft #2, departed vgt tower at XA48Z on an IFR published instrument departure procedure. Aircraft #1 flew southwest to the bank building approximately 3 1/2 mi southwest of vgt and then turned left, heading to the showboat approximately 100 degree heading. Aircraft 2 departed runway 12 to a right turn, heading 220 degrees. Aircraft #2 spilled out of class D airspace into class B airspace and was nose-to-nose with aircraft #1. These 2 procedures are not procedurally separated and as a level ii VFR airport we are required to separate planes in the class B airspace. Also, per LOA, both planes are shipped to separate frequencys in the same airspace. In a level 2 VFR environment, vgt should not be responsible for visual separation in class B airspace. Also a new departure procedure should keep all IFR departures off of vgt in vgt airspace.

Original NASA ASRS Text

Title: CTLR AT VGT TWR DEPARTS ACFT #1 VFR TO THE NW AND 3 MINS LATER DEPARTS ACFT #2 IFR TO THE SE. THE COURSES OF THE ACFT CONVERGED S OF THE ARPT AND THE RPTR CLAIMS AN NMAC OCCURRED.

Narrative: ACFT #1, A C402, DEPARTED VGT TWR ON A CODED DEP RTE AT XA45Z TO THE GRAND CANYON. HAWKER SIDLEY, ACFT #2, DEPARTED VGT TWR AT XA48Z ON AN IFR PUBLISHED INST DEP PROC. ACFT #1 FLEW SW TO THE BANK BUILDING APPROX 3 1/2 MI SW OF VGT AND THEN TURNED L, HDG TO THE SHOWBOAT APPROX 100 DEG HDG. ACFT 2 DEPARTED RWY 12 TO A R TURN, HDG 220 DEGS. ACFT #2 SPILLED OUT OF CLASS D AIRSPACE INTO CLASS B AIRSPACE AND WAS NOSE-TO-NOSE WITH ACFT #1. THESE 2 PROCS ARE NOT PROCEDURALLY SEPARATED AND AS A LEVEL II VFR ARPT WE ARE REQUIRED TO SEPARATE PLANES IN THE CLASS B AIRSPACE. ALSO, PER LOA, BOTH PLANES ARE SHIPPED TO SEPARATE FREQS IN THE SAME AIRSPACE. IN A LEVEL 2 VFR ENVIRONMENT, VGT SHOULD NOT BE RESPONSIBLE FOR VISUAL SEPARATION IN CLASS B AIRSPACE. ALSO A NEW DEP PROC SHOULD KEEP ALL IFR DEPS OFF OF VGT IN VGT AIRSPACE.
