A BE35 PLT TURNS TO HIS DEP HEADING TOO SOON AFTER TKOF FROM ABQ AND GETS A REPRIMAND FROM THE TWR. RPTR DISPUTES THE CTLR'S ASSERTION ON THE EARLY TURN.

Narrative

ON DEC/SUN/98; I DEPARTED ABQ ON AN IFR FLT PLAN TO LAS. AS BEST AS I RECALL; TWR CLRED ME FOR TKOF AS FOLLOWS: 'BONANZA XYZ; FLY HDG 310 DEGS AFTER DEP; CLRED FOR TKOF RWY 8.' I ACKNOWLEDGED; 'BONANZA XYZ; FLY HDG 310 DEGS; CLRED FOR TKOF RWY 8.' AFTER TKOF AND BEFORE REACHING THE DEP END OF RWY 8; I MADE A L TURN TO 310 DEGS. WITHIN 1 MIN OF COMPLETING THE TURN TO 310 DEGS; TWR CALLED ME SAYING THEY HAD TOLD ME NOT TO INITIATE MY TURN TO 310 DEGS UNTIL; 'AFTER XING THE DEP END OF RWY 8.' I ADVISED TWR I HAD NOT UNDERSTOOD SUCH A RESTR IN THE TKOF CLRNC. TWR ADVISED ME THE PURPOSE WAS TO AVOID OVERFLYING A HOSPITAL IN THE AREA. THERE WAS NO FURTHER COM BTWN ME AND THE TWR ON THE SUBJECT. I WAS THEN HANDED OFF BY TWR TO DEP CTL. I UNDERSTOOD NO RESTR IN THE CLRNC I RECEIVED REGARDING MY TURN TO 310 DEGS. MY READBACK OF THE CLRNC DID NOT ACKNOWLEDGE ANY RESTR. ON DEC/WED/98; I DEPARTED ABQ FROM RWY 8. THE TWR CTLR ON THAT DATE REQUESTED THAT I INITIATE A TURN TO 310 DEGS ASAP IN ORDER TO ACCOMMODATE FOLLOWING JET TFC. MY GND TRACK ON BOTH DAYS (DEC/WED/98; AND DEC/SUN/98) WAS IDENTICAL.
