Narrative:

Yvr approach informed us on initial contact of moderate turbulence below 8000 ft in vicinity of airport. They also advised us of windshear of 5-10 KTS reported at or around 1000 ft AGL. On approach; we had a good ride until turning base descending through 3000 ft for 2000 ft. Cleared the approach to runway 8L. Got continual moderate turbulence on approach with +15 to -5 KTS. Surface winds were 090 degrees at 12 KTS. Winds at our altitude 040 degrees at 25 KTS. In VFR conditions at 1000 ft; we got a +20 KTS followed by a loss of 10 KTS. I applied maximum power to get airspeed back. Simultaneously; got AFDS windshear warning. Hand flying approach; applied power and began to go around when airspeed recovered and we flew through the windshear. Having not yet climbed above GS and all indications appeared normal; elected to continue approach to a normal landing. Flight below the 1000 ft was smooth. I did not elect to do windshear recovery profile for several reason: 1) no convective activity. 2) shear was a wind event. 3) altitude above ground. 4) aircraft returned to a normal state. We had a short night the evening before in okc. Due to computer outage; we arrived okc at XA30. Got to sleep around XB30. Woke up 6 hours later. Fatigue may have had a minor impact on decision.

Title: B737-500 ON APCH TO YVR RECEIVED WINDSHEAR ALERT. STARTED RECOVERY MANEUVER BUT EXITED THE SHEAR QUICKLY. DISCONTINUED THE RECOVERY AND LANDED STRAIGHT AHEAD.

Narrative: YVR APCH INFORMED US ON INITIAL CONTACT OF MODERATE TURB BELOW 8000 FT IN VICINITY OF ARPT. THEY ALSO ADVISED US OF WINDSHEAR OF 5-10 KTS RPTED AT OR AROUND 1000 FT AGL. ON APCH; WE HAD A GOOD RIDE UNTIL TURNING BASE DSNDING THROUGH 3000 FT FOR 2000 FT. CLRED THE APCH TO RWY 8L. GOT CONTINUAL MODERATE TURB ON APCH WITH +15 TO -5 KTS. SURFACE WINDS WERE 090 DEGS AT 12 KTS. WINDS AT OUR ALT 040 DEGS AT 25 KTS. IN VFR CONDITIONS AT 1000 FT; WE GOT A +20 KTS FOLLOWED BY A LOSS OF 10 KTS. I APPLIED MAX PWR TO GET AIRSPD BACK. SIMULTANEOUSLY; GOT AFDS WINDSHEAR WARNING. HAND FLYING APCH; APPLIED PWR AND BEGAN TO GO AROUND WHEN AIRSPD RECOVERED AND WE FLEW THROUGH THE WINDSHEAR. HAVING NOT YET CLBED ABOVE GS AND ALL INDICATIONS APPEARED NORMAL; ELECTED TO CONTINUE APCH TO A NORMAL LNDG. FLT BELOW THE 1000 FT WAS SMOOTH. I DID NOT ELECT TO DO WINDSHEAR RECOVERY PROFILE FOR SEVERAL REASON: 1) NO CONVECTIVE ACTIVITY. 2) SHEAR WAS A WIND EVENT. 3) ALT ABOVE GND. 4) ACFT RETURNED TO A NORMAL STATE. WE HAD A SHORT NIGHT THE EVENING BEFORE IN OKC. DUE TO COMPUTER OUTAGE; WE ARRIVED OKC AT XA30. GOT TO SLEEP AROUND XB30. WOKE UP 6 HRS LATER. FATIGUE MAY HAVE HAD A MINOR IMPACT ON DECISION.
