Narrative

FLAP FAILURE OCCURRED JUST PRIOR TO LOC INTERCEPT. BROKE OFF APCH. CAPT DIRECTED ME TO COMPLETE APPROPRIATE CHKLIST AND CONTACT COMPANY TO CONFIRM LNDG DISTANCES SUITABLE FOR AVP. CAPT SAID HE WOULD HANDLE #1 RADIO AND COMMUNICATE WITH ATC. AS I COMPLETED CHKLIST; I HEARD ATC ADVISE 'PROCEED DIRECT LAKE HENRY (LHY) VOR AND HOLD E ON 090 DEG RADIAL AT 6000 FT STANDARD TURNS.' CAPT PROGRAMMED FMS. I DID NOT CONFIRM INSTRUCTIONS OR VERIFY FMS PROGRAM. WE WERE UNABLE TO CONTACT COMPANY DIRECT AND ASKED FOR CLB TO 10000 FT. ATC AUTH 8000 FT. COMPANY PERSONNEL ON GND AT AVP AND OUTBOUND CAPT WORKED LAND LINE COM WITH COMPANY; RELAYING DATA TO ME FOR CONCURRENCE. ATC CALLED AND ASKED IF WE WERE HOLDING E OF LHY OR W. WE CONFIRMED W. ATC STATED WE WERE INSTRUCTED E ON 090 DEGS. CAPT CHKED PROGRAM AND REALIZED HE HAD PUT THE WRONG INBOUND HEADING/RADIAL. HE SELECTED INBOUND CRS 090 DEGS WHICH PUT US ON THE 270 DEG RADIAL WITH AN INBOUND HEADING TO LHY OF 090 DEGS. THE COLLINS FMS-4100 MANUAL SHOWS THIS AS CORRECT. OUR ACFT ARE EQUIPPED WITH COLLINS FMS-4200. IN RETROSPECT; WE SHOULD HAVE DELAYED ALL CHKLIST EXCEPT FOR ESSENTIAL ONE FOR SAFETY OF FLT AND DELAYED ME LEAVING THE COM LOOP UNTIL WE WERE ESTABLISHED IN THE HOLD. IT ALL GOES BACK TO AVIATE; NAV; COMMUNICATE.
