Narrative:

At initial contact with MD80, spacing behind a heavy B767 was 4 mi. Traffic was issued to MD80, caution wake turbulence issued, and MD80 was turned to establish separation. Departure control only moderately busy. Incident reported to supervisor who reported it to tower personnel. No explanation received. Suspect tower was in a hurry and disregarded safety for expedience. Normally we see no corrective action in incidents of this type, so submitting the NASA report is the only alternative to remedying the situation.

Title: A DEP CTLR'S RPT ON THE LACK OF PROPER SPACING FOR WAKE VORTEX SEPARATION BTWN A PRECEDING B767 AND A FOLLOWING MD80 AS SET UP DURING TKOF PROCS BY TWR CTLR AT PHX, AZ.

Narrative: AT INITIAL CONTACT WITH MD80, SPACING BEHIND A HVY B767 WAS 4 MI. TFC WAS ISSUED TO MD80, CAUTION WAKE TURB ISSUED, AND MD80 WAS TURNED TO ESTABLISH SEPARATION. DEP CTL ONLY MODERATELY BUSY. INCIDENT RPTED TO SUPVR WHO RPTED IT TO TWR PERSONNEL. NO EXPLANATION RECEIVED. SUSPECT TWR WAS IN A HURRY AND DISREGARDED SAFETY FOR EXPEDIENCE. NORMALLY WE SEE NO CORRECTIVE ACTION IN INCIDENTS OF THIS TYPE, SO SUBMITTING THE NASA RPT IS THE ONLY ALTERNATIVE TO REMEDYING THE SIT.
