Narrative:

At approximately XA00, crew member (PF) received clearance from aus clearance delivery as follows: cleared as filed, centex one, navasota transition, direct lufkin as filed. Squawk XXXX. Upon programming FMS departure, centex one was entered. 2 choices were available for transitions, navy's and tnv. Crew member (PF) inadvertently entered navy's (sounds like navasota) instead of tnv (navasota). After departing runway 35R, aus departure assigned heading 010 degrees. Crew member, PNF, acknowledged. Next instruction was 'present heading to intercept outbound radial' (no specific NAVAID or radial mentioned). We proceeded to intercept centex (cwk) 040 degrees to navys intersection. After handoff to ZHU, we were instructed to proceed direct navasota (tnv) and asked what last route was assigned by aus departure. Crew member (PNF) responded, 'present heading to intercept outbound radial.' ZHU commented 'we had remained in aus airspace.' no further questions or instructions followed from ATC regarding prior clrncs. Crew members agree, with 2 like sounding (pronouncing) fixes on centex departure, chance of error is increased. Both crew members must verify FMS programming and clrncs. Supplemental information from acn 608116: after flying 060 degrees for a min or so, we saw that that heading would not intercept the radial. When we were told to intercept the radial we thought that we should intercept the 040 degree radial, not the 088 degree radial. When it became obvious to ATC that we were not intercepting the 088 degrees we were given clearance direct tnv. Due to a rush or an effort to understand (any distraction) a mistake may be made, as it was in our case, between 'navys and navasota.'

Title: H25B DEP FROM AUS ENTERED WRONG TRANSITION INITIATING TRACK DEV.

Narrative: AT APPROX XA00, CREW MEMBER (PF) RECEIVED CLRNC FROM AUS CLRNC DELIVERY AS FOLLOWS: CLRED AS FILED, CENTEX ONE, NAVASOTA TRANSITION, DIRECT LUFKIN AS FILED. SQUAWK XXXX. UPON PROGRAMMING FMS DEP, CENTEX ONE WAS ENTERED. 2 CHOICES WERE AVAILABLE FOR TRANSITIONS, NAVY'S AND TNV. CREW MEMBER (PF) INADVERTENTLY ENTERED NAVY'S (SOUNDS LIKE NAVASOTA) INSTEAD OF TNV (NAVASOTA). AFTER DEPARTING RWY 35R, AUS DEP ASSIGNED HDG 010 DEGS. CREW MEMBER, PNF, ACKNOWLEDGED. NEXT INSTRUCTION WAS 'PRESENT HDG TO INTERCEPT OUTBOUND RADIAL' (NO SPECIFIC NAVAID OR RADIAL MENTIONED). WE PROCEEDED TO INTERCEPT CENTEX (CWK) 040 DEGS TO NAVYS INTXN. AFTER HDOF TO ZHU, WE WERE INSTRUCTED TO PROCEED DIRECT NAVASOTA (TNV) AND ASKED WHAT LAST RTE WAS ASSIGNED BY AUS DEP. CREW MEMBER (PNF) RESPONDED, 'PRESENT HDG TO INTERCEPT OUTBOUND RADIAL.' ZHU COMMENTED 'WE HAD REMAINED IN AUS AIRSPACE.' NO FURTHER QUESTIONS OR INSTRUCTIONS FOLLOWED FROM ATC REGARDING PRIOR CLRNCS. CREW MEMBERS AGREE, WITH 2 LIKE SOUNDING (PRONOUNCING) FIXES ON CENTEX DEP, CHANCE OF ERROR IS INCREASED. BOTH CREW MEMBERS MUST VERIFY FMS PROGRAMMING AND CLRNCS. SUPPLEMENTAL INFO FROM ACN 608116: AFTER FLYING 060 DEGS FOR A MIN OR SO, WE SAW THAT THAT HDG WOULD NOT INTERCEPT THE RADIAL. WHEN WE WERE TOLD TO INTERCEPT THE RADIAL WE THOUGHT THAT WE SHOULD INTERCEPT THE 040 DEG RADIAL, NOT THE 088 DEG RADIAL. WHEN IT BECAME OBVIOUS TO ATC THAT WE WERE NOT INTERCEPTING THE 088 DEGS WE WERE GIVEN CLRNC DIRECT TNV. DUE TO A RUSH OR AN EFFORT TO UNDERSTAND (ANY DISTR) A MISTAKE MAY BE MADE, AS IT WAS IN OUR CASE, BTWN 'NAVYS AND NAVASOTA.'
