Narrative:

WX cavu wind 300 at 12 temperature 10 degree F. I arrived and found the small aircraft I rented to be totally covered in snow and ice. Line crewman pulled small aircraft into a hangar for deice because their alcohol system wasn't working. All snow and ice was melted enough to remove with a shop broom. After brooming all snow and ice was gone but the plane was all wet. The passengers and myself found some chamois rags and dried the airplane to my satisfaction. Some of the control surface hinges were wet, but just wet, no ice or snow anywhere. Preflight was accomplished with no problems. Start-up and taxi took about 10 min. During taxi I checked controls 2 or 3 times with no problems. But I didn't check trim to see if it was frozen. During before takeoff check I moved trim to takeoff position with no problem. During pretkof check, I was satisfied. Takeoff roll was fine everything was working properly. Shortly after liftoff, I noticed the airspeed was reading low. I immediately lower nose and retrimmed but couldn't because the trim wheel was frozen. I analyzed the problem and then informed tower that my trim was frozen, my airspeed read 0, my vsi registered a 600 FPM climb. Nothing in the pitot static system was reliable. The airplane was flying fine. I told tower I wanted to play around with some simulated approachs before I tried a real one. Circling to land my airspeed indicator came back on line, but the altimeter and vsi were still acting erratically. Tower gave me a long straight-in and a landing was accomplished uneventfully. This was my first experience with these type of circumstances. Up until I started flying at this FBO, I have never rented an airplane that wasn't hangared.

Title: GA SMA TOOK OFF THEN LOST ALL STATIC INSTRUMENTS. ACFT HAD BEEN TIED DOWN OUTSIDE OVERNIGHT AS A SNOW STORM PASSED AND WATER HAD COLLECTED IN PITOT STATIC SYSTEM.

Narrative: WX CAVU WIND 300 AT 12 TEMP 10 DEG F. I ARRIVED AND FOUND THE SMA I RENTED TO BE TOTALLY COVERED IN SNOW AND ICE. LINE CREWMAN PULLED SMA INTO A HANGAR FOR DEICE BECAUSE THEIR ALCOHOL SYS WASN'T WORKING. ALL SNOW AND ICE WAS MELTED ENOUGH TO REMOVE WITH A SHOP BROOM. AFTER BROOMING ALL SNOW AND ICE WAS GONE BUT THE PLANE WAS ALL WET. THE PAXS AND MYSELF FOUND SOME CHAMOIS RAGS AND DRIED THE AIRPLANE TO MY SATISFACTION. SOME OF THE CTL SURFACE HINGES WERE WET, BUT JUST WET, NO ICE OR SNOW ANYWHERE. PREFLT WAS ACCOMPLISHED WITH NO PROBS. START-UP AND TAXI TOOK ABOUT 10 MIN. DURING TAXI I CHKED CTLS 2 OR 3 TIMES WITH NO PROBS. BUT I DIDN'T CHK TRIM TO SEE IF IT WAS FROZEN. DURING BEFORE TKOF CHK I MOVED TRIM TO TKOF POS WITH NO PROB. DURING PRETKOF CHK, I WAS SATISFIED. TKOF ROLL WAS FINE EVERYTHING WAS WORKING PROPERLY. SHORTLY AFTER LIFTOFF, I NOTICED THE AIRSPD WAS READING LOW. I IMMEDIATELY LOWER NOSE AND RETRIMMED BUT COULDN'T BECAUSE THE TRIM WHEEL WAS FROZEN. I ANALYZED THE PROB AND THEN INFORMED TWR THAT MY TRIM WAS FROZEN, MY AIRSPD READ 0, MY VSI REGISTERED A 600 FPM CLB. NOTHING IN THE PITOT STATIC SYS WAS RELIABLE. THE AIRPLANE WAS FLYING FINE. I TOLD TWR I WANTED TO PLAY AROUND WITH SOME SIMULATED APCHS BEFORE I TRIED A REAL ONE. CIRCLING TO LAND MY AIRSPD INDICATOR CAME BACK ON LINE, BUT THE ALTIMETER AND VSI WERE STILL ACTING ERRATICALLY. TWR GAVE ME A LONG STRAIGHT-IN AND A LNDG WAS ACCOMPLISHED UNEVENTFULLY. THIS WAS MY FIRST EXPERIENCE WITH THESE TYPE OF CIRCUMSTANCES. UP UNTIL I STARTED FLYING AT THIS FBO, I HAVE NEVER RENTED AN AIRPLANE THAT WASN'T HANGARED.
