FATIGUED AND OPERATING FROM AN UNFAMILIAR ARPT; FO RAISES FLAPS INSTEAD OF GEAR AFTER LIFTOFF.

Narrative

I MADE A TERRIBLE MISTAKE DURING THE TKOF/DEP. WHEN COMMANDED TO RAISE THE GEAR; I RAISED THE FLAPS INSTEAD. IT WAS THE CAPT'S LEG; LIGHT WT (258900 LBS); FLAPS 15 DEGS; ICAO CLBOUT. CORRECTED V1/VR/V2 WERE 120 KTS/124 KTS/133 KTS. GND OPS AND RWY 19 TKOF ROLL WERE NORMAL. I CALLED V1/VR/V2 AS APPROPRIATE. AT V2; CAPT SLOWLY ROTATED TO ABOUT 17 DEGS. WHEN SAFELY AIRBORNE AND CLBING; HE CALLED; 'POSITIVE CLB; GEAR UP; LNAV.' MISTAKENLY; I RAISED THE FLAP HANDLE (WHICH NEITHER OF US NOTICED AT THE TIME). ABOUT 1500 FT WHEN CAPT CALLED 'VNAV' WAS WHEN I REALIZED WHAT I HAD DONE. (THE CAPT HAD NOTICED A BIT EARLIER AND HAD LOWERED THE NOSE TO ACCELERATE.) I THEN RAISED THE GEAR; AS CAPT SPED UP TO CLEAN MANEUVERING AND NORMAL CLB PROFILE. AT NO TIME DID WE EXPERIENCE ANY BURBLE; STICK SHAKER; OR STALL WARNING. REMAINDER OF FLT WAS UNEVENTFUL. I'M STILL RESOLVING WHY THIS HAPPENED. I BELIEVE FATIGUE AND ARPT FAMILIARITY WERE CONTRIBUTING FACTORS. I HAD SLEPT WELL THE PREVIOUS NIGHT (8-9 HRS); BUT MY CIRCADIAN RHYTHM WAS STILL IN DISARRAY FROM THE 'ALL-NIGHTER.' THOUGH I DID NOT FEEL EXCESSIVELY TIRED; I ALSO DID NOT FEEL AS SHARP AS USUAL WHICH MAY HAVE BEEN DUE TO EFFECTS OF CUMULATIVE FATIGUE. IT WAS ALSO MY FIRST TIME INTO SUMU. HENCE; I WASN'T FAMILIAR WITH THE NORMAL OPERATING PATTERNS (ROUTINGS; TAXIING; FLAPS 15 DEG TKOF). THE CAPT DID EDUCATE ME ON THE USUAL PATTERNS; AND WE THOROUGHLY DISCUSSED THE FLAPS 15 DEG TKOF (I WAS SURPRISED FLAPS 5 DEGS WAS NOT APPLICABLE GIVEN OUR LIGHT WT). SO; I THINK (SUBCONSCIOUSLY) FLAPS WERE ON MY MIND; AND COUPLED WITH THE FATIGUE AND FAMILIARITY FACTORS; I RAISED THE FLAPS TOO SOON. I REALIZE THE GRAVENESS OF MY ERROR. I HAVE NEVER DONE ANYTHING LIKE THAT BEFORE. BUT; I ALSO HAVE LEARNED MUCH FROM THIS EXPERIENCE. THOUGH I AM PRETTY MUCH AN SOP GUY; I WILL BECOME A TOTAL SOP GUY. I WILL BETTER EDUCATE MYSELF ON UNFAMILIAR AIRFIELDS AND PAY EVEN CLOSER ATTN TO ANY/ALL DETAILS. I WILL ALSO VERIFY I AM OPERATING THE PROPER ITEM. BY DOING THESE THINGS; I AM SURE I WILL NEVER DO SOMETHING LIKE THIS AGAIN; NO MATTER HOW TIRED OR DISTR I AM.
