Narrative:
I was cleared for departure on runway 12 at sac. Runway visual range I am guessing was probably around 1000 ft. I developed full power from the engine, and when everything was in the green, I released the brakes. At 80 KTS I rotated and I remember calling out 500 FPM. I did not incorporate a proper scan technique and the aircraft went into a left bank. I was supposed to turn right to 150 degrees. I tried doing so and before I knew it we were in a steep nose high attitude, just poking through the fog layer. I immediately overcorrected by pushing full forward on the control yoke. Within seconds we broke through underneath the fog and were heading straight for the ground. I then pulled back as hard as I could on the yoke and just barely leveled of, when I struck my left wing on something, or so I thought. I regained control of the aircraft and established straight and level attitude above the overcast. My passenger said he saw something trailing behind the left wingtip. It was the pitot tube wire. Then I noticed I had no airspeed indication. I tried to relax and calm down a bit considering what had just happened. I thought the worst and declared a distress situation with sac approach control. I told them that I might have struck my landing gear. They vectored me to cameron park airport, which was above the fog. After a few low passes over the airport I was told that my gear was intact. I then made a successful landing.

Title: SPATIAL DISORIENTATION SUFFERED BY LOW TIME PLT IN IMC TKOF PROC. LOSS OF ACFT CTL. ACFT DAMAGED IN GND CONTACT WITH OBSTRUCTION.
Narrative: I WAS CLRED FOR DEP ON RWY 12 AT SAC. RWY VISUAL RANGE I AM GUESSING WAS PROBABLY AROUND 1000 FT. I DEVELOPED FULL PWR FROM THE ENG, AND WHEN EVERYTHING WAS IN THE GREEN, I RELEASED THE BRAKES. AT 80 KTS I ROTATED AND I REMEMBER CALLING OUT 500 FPM. I DID NOT INCORPORATE A PROPER SCAN TECHNIQUE AND THE ACFT WENT INTO A L BANK. I WAS SUPPOSED TO TURN R TO 150 DEGS. I TRIED DOING SO AND BEFORE I KNEW IT WE WERE IN A STEEP NOSE HIGH ATTITUDE, JUST POKING THROUGH THE FOG LAYER. I IMMEDIATELY OVERCORRECTED BY PUSHING FULL FORWARD ON THE CTL YOKE. WITHIN SECONDS WE BROKE THROUGH UNDERNEATH THE FOG AND WERE HDG STRAIGHT FOR THE GND. I THEN PULLED BACK AS HARD AS I COULD ON THE YOKE AND JUST BARELY LEVELED OF, WHEN I STRUCK MY L WING ON SOMETHING, OR SO I THOUGHT. I REGAINED CTL OF THE ACFT AND ESTABLISHED STRAIGHT AND LEVEL ATTITUDE ABOVE THE OVCST. MY PAX SAID HE SAW SOMETHING TRAILING BEHIND THE L WINGTIP. IT WAS THE PITOT TUBE WIRE. THEN I NOTICED I HAD NO AIRSPD INDICATION. I TRIED TO RELAX AND CALM DOWN A BIT CONSIDERING WHAT HAD JUST HAPPENED. I THOUGHT THE WORST AND DECLARED A DISTRESS SIT WITH SAC APCH CTL. I TOLD THEM THAT I MIGHT HAVE STRUCK MY LNDG GEAR. THEY VECTORED ME TO CAMERON PARK ARPT, WHICH WAS ABOVE THE FOG. AFTER A FEW LOW PASSES OVER THE ARPT I WAS TOLD THAT MY GEAR WAS INTACT. I THEN MADE A SUCCESSFUL LNDG.
