Mooney pilot found, during IFR climb after takeoff, that his airspeed went to zero and the altimeter did not change from ground level. ATC vectored him to another airport for an ILS approach. Postflt inspection revealed that both static tube ports were taped over for washing prior to flight.

Narrative:
Small aircraft came out of annual on jul/sat/01, was test flown, all checked ok. Aircraft was washed on afternoon of jul/sat/01. Filed void time IFR departure. Takeoff from I68 was normal -- 65 KT liftoff, 85 KT climb out. On climb out, I noticed airspeed began to drop, then went to zero. Also on climb out, altitude did not change from ground level altitude. Converted to ground speed and altitude readings on IFR certified GPS. Informed dayton approach of problem. Refused return to I68 or diversion to smaller airports. During this time, continued climb above cloud tops which put me above 4000 ft assigned at. Continued climb and communication with dayton approach to 9000 ft. Determined cmh had acceptable WX, diverted, made ILS approach. Found 3/4 inch by 3/4 inch tape covering both static ports. After excitement died down, should have opened alternate static. Discussed problem with line service and remediation options. Solution: conduct better, detailed preflight chkout.

Title: MOONEY PLT FOUND, DURING IFR CLB AFTER TKOF, THAT HIS AIRSPD WENT TO ZERO AND THE ALTIMETER DID NOT CHANGE FROM GND LEVEL. ATC VECTORED HIM TO ANOTHER ARPT FOR AN ILS APCH. POSTFLT INSPECTION REVEALED THAT BOTH STATIC TUBE PORTS WERE TAPED OVER FOR WASHING PRIOR TO FLT.
Narrative: SMA CAME OUT OF ANNUAL ON JUL/SAT/01, WAS TEST FLOWN, ALL CHKED OK. ACFT WAS WASHED ON AFTERNOON OF JUL/SAT/01. FILED VOID TIME IFR DEP. TKOF FROM I68 WAS NORMAL -- 65 KT LIFTOFF, 85 KT CLBOUT. ON CLBOUT, I NOTICED AIRSPD BEGAN TO DROP, THEN WENT TO ZERO. ALSO ON CLBOUT, ALT DID NOT CHANGE FROM GND LEVEL ALT. CONVERTED TO GND SPD AND ALT READINGS ON IFR CERTIFIED GPS. INFORMED DAYTON APCH OF PROB. REFUSED RETURN TO I68 OR DIVERSION TO SMALLER ARPTS. DURING THIS TIME, CONTINUED CLB ABOVE CLOUD TOPS WHICH PUT ME ABOVE 4000 FT ASSIGNED AT. CONTINUED CLB AND COM WITH DAYTON APCH TO 9000 FT. DETERMINED CMH HAD ACCEPTABLE WX, DIVERTED, MADE ILS APCH. FOUND 3/4 INCH BY 3/4 INCH TAPE COVERING BOTH STATIC PORTS. AFTER EXCITEMENT DIED DOWN, SHOULD HAVE OPENED ALTERNATE STATIC. DISCUSSED PROB WITH LINE SVC AND REMEDIATION OPTIONS. SOLUTION: CONDUCT BETTER, DETAILED PREFLT CHKOUT.
