COMMUTER LTT LANDS ON CLOSED RWY.

Narrative

THE CAPT CHKED THE WX AND NOTAMS ON THE COMPANY'S COMPUTER WX EQUIP PRIOR TO DEP. NO MENTION WAS MADE ON THE PRINTOUT OF RWY 14 BEING CLOSED UNDER NOTAMS LISTED FOR THE AREA. SUBSEQUENT TO THIS EVENT IT WAS DISCOVERED THAT THERE ARE SEVERAL WAYS TO REQUEST NOTAMS FROM THE COMPUTER. SOME METHODS APPARENTLY DO NOT GIVE COMPLETE INFORMATION. OUR COMPANY DOES NOT SPECIFY HOW A PLT SHOULD REQUEST WX AND NOTAMS FROM THE COMPUTER; MAYBE IT SHOULD. THE CAPT (PNF) CHKED THE AWOS ABOUT 20 MINS FROM ARR. THERE WAS NO MENTION OF RWY 14 CLOSURE. ALSO AT ABOUT THIS TIME; THE CAPT MADE NUMEROUS ATTEMPTS TO CONTACT OUR COMPANY AT IMPERIAL TO LET THEM KNOW WE WERE INBOUND AND TO CHK WX AGAINST THE AWOS (WINDS; TEMP; ETC). NO INFO WAS EVER PASSED TO US; AS HE WAS UNABLE TO RAISE COMPANY ON THE FREQ. WE ARE NOW ONLY A FEW MI FROM THE ARPT; AND 3 POSSIBLE SOURCES OF NOTIFICATION THAT RWY 14 WAS CLOSED HAD NOT SUCCEEDED IN ALERTING US TO THAT FACT. OF COURSE THE WINDS WERE FAVORING RWY 14 (160 DEGS 10 KTS APPROX) AND WE WERE PLANNING OUR APCH TO RWY 14. BY THIS TIME WE HAD RPTED THE ARPT IN SIGHT; AND HAD CANCELLED IFR WITH ZLA. WE ARRIVED IN THE ARPT VICINITY SLIGHTLY HIGH AND TO THE NNW OF THE FIELD. THE CAPT SUGGESTED A L 270 DEG TURN TO ENTER ON A L BASE FOR RWY 14 AND THAT WE DID. (NO OTHER ACFT WERE RPTING IN THE AREA AS WE WERE BROADCASTING OUR POS.) IN RETROSPECT; A 45 DEG ENTRY TO THE L DOWNWIND MAY HAVE AFFORDED THE CAPT A BETTER VIEW OF THE INTENDED RWY; ALERTING US TO ITS CLOSURE. THE BASE LEG AND FINAL APCH WENT AS PLANNED. IT WASN'T UNTIL EXTREMELY SHORT FINAL THAT EITHER OF US NOTICED THAT RWY WAS CLOSED. THE APCH AND LNDG CONTINUED; AS IT SEEMED A GREATER RISK TO GAR SO VERY CLOSE TO TOUCHDOWN. LNDG ITSELF WAS UNEVENTFUL. OTHER POSSIBLE FACTORS INCLUDE: CAPT ON REDUCED REST; OVERNIGHT. MOMENT OF DISBELIEF; NOT KNOWING AHEAD OF TIME (ABOVE STATEMENT). A CLR AND UNOBSTRUCTED RWY IS NOT WHAT ONE EXPECTS TO BE IN FRONT OF HIM; IF IT IS CLOSED. SUPPLEMENTAL INFO FROM ACN 314786: CAUSAL FACTORS: I WAS ON TEMP DUTY IN SOUTHERN CALIFORNIA. MY FO WAS NEW TO THE COMPANY WITH THIS BEING HIS FIRST DAY AFTER IOE. IMPERIAL COMPANY PERSONNEL DID NOT RESPOND TO RPTED INQUIRES FOR 'ARPT CONDITIONS.' SINCE OVER 15 MIN PRIOR TO TOUCHDOWN MY INQUIRIES WERE MET WITH 'STANDBY.' NO TWR ON FIELD. YELLOW 'X' ON RWY NOT APPARENT ON A 3 DEG GS. OVERHEAD ENTRY NOT ADVISABLE AT IMPERIAL DUE TO PROX TO MIL ARPT FLT PATHS. AFTER LNDG I TALKED TO ARPT PERSONNEL TO INSURE THAT THERE WERE NO PROBS CAUSED BY THE LNDG. I WAS ASSURED THAT THERE WAS NOT.
