HDG TRACK DEV IN A GROSS NAV ERROR INCIDENT.

Narrative

FLT WAS FILED SNA-DFW VIA THE MUSEL 5 DEP OCN TRANSITION DIRECT BZA J-2 GBN...KDFW. CLRNC DELIVERY CHANGED THE CLRNC TO MUSEL 5 VECTORS TO THE SXC 061 THEN THE SXC 061 TO THE SLI 095 TO THE PDZ 135 J-2 BZA AS FILED. THE FLT WAS A SPECIAL ARPT QUALIFICATION WITH THE LINE CHK AIRMAN IN THE R SEAT. THE FLT WAS 1 HR LATE. THE LINE CHK AIRMAN LOADED THE RTE CHANGE IN THE FMS JUST PRIOR TO PUSHBACK USING PLACE BEARING METHOD TO ESTABLISH THE SXC 061/SLI 095 AND THE SLI 095/PDZ 135 FIXES. THE FIX PAGE USING PDZ AND 135 DEG RADIAL AS A DOWN TRACK FIX FUNCTION WAS USED TO ESTABLISH THE PDZ 135 J-2 FIX. IN THE RUSH TO CUT THE DELAY; HE MISSED THE FACT THAT THE ORIGINAL TRACK WAS OCN DIRECT BZA THEN J-2. CONSEQUENTLY; THE DOWN TRACK FIX WAS ESTABLISHED N OF J-2 ON A LINE BTWN OCN AND BZA. ZLA QUESTIONED OUR RTE AND I; THE LINE CHK AIRMAN; GAVE THEM OUR RTE. WE WERE INFORMED AT THAT TIME WE WERE N OF OUR CLRED RTE. I DISCOVERED MY MISTAKE AND ENTERED THE PROPER DATA AND THE FLT PROCEEDED NORMALLY FROM THAT POINT. CONTRIBUTING FACTORS -- 1) RUSHING TO MAKE UP TIME. 2) MISREADING THE POINT ON THE FLT PLAN WHICH BEGAN J-2. LAST MIN CLRNC CHANGE.
