Shortly after departure I noticed that airspeed on my; captain side; is bleeding off following by zero indication on vertical speed indicator and no climb showing on altimeter. I immediately turn on my pitot static anti-ice system but there was no change and there was no ice present on ice probe either. At that time I looked up on copilot instruments and they were indicating correctly my climb so I continue climbing to my cruising altitude of 7000 ft by reference on copilot instruments. Few mins after I level off on my cruising altitude I start losing pitot/static instruments on copilot side also. At that moment I advised ATC that I do not know what is my altitude and airspeed but that I can stay VFR and proceed to my destination VFR. They let me do it and I landed safely. After landing I advised our company maintenance about the problem.
Original NASA ASRS Text
Title: A BEECHCRAFT 99 ACFT EXPERIENCED A COMPLETE LOSS OF VERT AIRSPD AND ALTIMETER INDICATION AFTER TKOF. FLT CONTINUED VFR TO ORIGINAL DEST.
Narrative: SHORTLY AFTER DEP I NOTICED THAT AIRSPD ON MY; CAPT SIDE; IS BLEEDING OFF FOLLOWING BY ZERO INDICATION ON VERT SPD INDICATOR AND NO CLB SHOWING ON ALTIMETER. I IMMEDIATELY TURN ON MY PITOT STATIC ANTI-ICE SYS BUT THERE WAS NO CHANGE AND THERE WAS NO ICE PRESENT ON ICE PROBE EITHER. AT THAT TIME I LOOKED UP ON COPLT INSTS AND THEY WERE INDICATING CORRECTLY MY CLB SO I CONTINUE CLBING TO MY CRUISING ALT OF 7000 FT BY REF ON COPLT INSTS. FEW MINS AFTER I LEVEL OFF ON MY CRUISING ALT I START LOSING PITOT/STATIC INSTS ON COPLT SIDE ALSO. AT THAT MOMENT I ADVISED ATC THAT I DO NOT KNOW WHAT IS MY ALT AND AIRSPD BUT THAT I CAN STAY VFR AND PROCEED TO MY DEST VFR. THEY LET ME DO IT AND I LANDED SAFELY. AFTER LNDG I ADVISED OUR COMPANY MAINT ABOUT THE PROB.
