ATX PLT HAD TO TAKE EVASIVE ACTION TURNS CLB AWAY FROM HIGHER TERRAIN S OF ARPT WHEN HE WAS UNABLE TO ESTABLISH COM WITH PHX TRACON DEP CTLR. AFTER SECOND XMISSION THAT HE WAS TURNING CLBING TO AVOID TERRAIN; RPTR STATES A DIFFERENT CTLR ISSUES FURTHER CLRNC ON COURSE. PLT PERCEIVES CTLR EFFORT TO DISCOURAGE CLASS B USE FROM 'SMALL NON SCHEDULED ACFT.'

Narrative

CLRNC FROM PHX TO IWA INITIALLY RWY HDG (DEPARTING RWY 26R) CLB TO AND MAINTAIN 3000 FT. DEP FREQ 124.1. AFTER TKOF; THE LCL CTLR GAVE US A HDG OF 220 DEGS. AFTER CLRING THE S RWY DEP CORRIDOR; WE WERE GIVEN A TURN S (190 DEGS). WE WERE THEN DIRECTED TO CONTACT DEP. THE DEP CTLR HAD OTHER ACR TFC AND DID NOT ACKNOWLEDGE OUR INITIAL CALL. A SECOND CALL WAS MADE AS WE CONTINUED AT 3000 FT AND AGAIN WAS NOT ACKNOWLEDGED. THE DEP CTLR CONTINUED TO COMMUNICATE WITH SCHEDULED ACRS. AIRSPD WAS SLOWED TO 160 KTS TO GIVE THE CTLR MORE TIME TO RESPOND; BUT WE WERE NEVER ACKNOWLEDGED. APCHING THE TERRAIN OF THE S MOUNTAIN RANGE (3000 FT MSL); WE WERE FORCED TO TURN OFF OUR ASSIGNED HDG TO AVOID TERRAIN. WE XMITTED 'ACFT X TURNING R FOR TERRAIN AVOIDANCE.' THE FREQ WENT DEAD SILENT FOR 10-20 SECONDS. WE XMITTED 'ACFT X CONTINUING R TURN FOR TERRAIN AVOIDANCE.' A DIFFERENT CTLR THEN CAME ON FREQ AND CLRED US TO A HIGHER ALT AND VECTORED US AROUND THE W END OF THE MOUNTAIN RANGE. THE REST OF THE FLT WAS UNEVENTFUL. PHX APCH CONTINUES ON A DAILY BASIS TO VECTOR SMALL ACFT AND NON SCHEDULED LARGE ACFT AT LOW ALTS OVER TERRAIN S OF THE ARPT; IN WHAT WOULD APPEAR TO BE AN EFFORT TO GET THEM OUT OF CLASS B AIRSPACE ASAP. THERE HAS ALSO BEEN A NATIONALLY PUBLISHED EFFORT BY PHX APCH TO RESTRICT 'SMALL' ACFT FROM CLASS B AIRSPACE AROUND PHX. THE PROC OF RUNNING ACFT AT LOW ALTS REQUIRES FLCS TO ROUTINELY REQUEST HIGHER ALTS OR REFUSE ASSIGNED VECTORS TO BE SAFE AND COMPLY WITH FARS. THIS SIT COULD BE AVOIDED IF PHX APCH WOULD PROVIDE THE SAME LEVEL OF SVC TO SMALL ACFT AND NON SCHEDULED LARGE ACFT THEY PROVIDE TO SCHEDULED ACR TFC AND WOULD APPLY SIMILAR STANDARDS TO DEP PROCS. THE PERCEPTION BY AIR TFC CTLRS OF 'LITTLE AIRPLANE; BIG AIRPLANE' CONTINUES TO PUT THE SMALL GUYS IN THE RANKS OF SECOND CLASS CITIZENS.
