Narrative:

On departure from tpa all phases of the flight proceeded normally until recognition of a problem occurred after liftoff at approximately 200' MSL. Acceleration, airspeed indications, ivsi, and altitude as normally expected until approximately 200' when the ivsi and altimeter gave initial indications of an anomaly. Altitude indications had stopped at 200' and the ivsi was not providing the normally expected rate of climb. However, the airspeed indications appeared appropriate for the conditions. The aircraft continued to climb and topped the WX (fog) at 1200' MSL. An emergency was declared an the flight proceeded to mco, which was VMC, as filed. The altitude was maintained visly and backed up with the radio altimeter. Airspeed was flown as presented by the indicator. ATC provided ground speed readouts for airspeed control as the aircraft approached mco. An uneventful ILS approach with normal flap 30 degree landing were made on runway 35. During the flight the limiting design speed of the flaps and leading edge devices was exceeded due to the actual speed of the aircraft being much greater than was indicated. On flight termination at mco it was discovered that the static ports had been covered while the aircraft was washed and the tape was not removed when the aircraft was returned to the line.

Title: AT APPROX 200' AGL AFTER LOW VISIBILITY TKOF FLT CREW OF LGT RECOGNIZED AN ALTIMETRY AND COMPUTED AIRSPEED PROBLEM. DECLARED AN EMERGENCY AND PROCEEDED TO MCO WHERE WX WAS VFR. OBTAINED ESTIMATED AIRSPEEDS FROM ARTCC. HOWEVER FLAPS SPEEDS WERE EXCEEDED ON APCH AN SOME DAMAGE OCCURRED TO LEADING EDGE FLAPS AND TRAILING EDGE FLAPS. LNDG WAS ACCOMPLISHED WITHOUT OTHER INCIDENT. STATIC PORTS HAD BEEN COVERED FOR ACFT WASHING.

Narrative: ON DEP FROM TPA ALL PHASES OF THE FLT PROCEEDED NORMALLY UNTIL RECOGNITION OF A PROB OCCURRED AFTER LIFTOFF AT APPROX 200' MSL. ACCELERATION, AIRSPD INDICATIONS, IVSI, AND ALT AS NORMALLY EXPECTED UNTIL APPROX 200' WHEN THE IVSI AND ALTIMETER GAVE INITIAL INDICATIONS OF AN ANOMALY. ALT INDICATIONS HAD STOPPED AT 200' AND THE IVSI WAS NOT PROVIDING THE NORMALLY EXPECTED RATE OF CLB. HOWEVER, THE AIRSPD INDICATIONS APPEARED APPROPRIATE FOR THE CONDITIONS. THE ACFT CONTINUED TO CLB AND TOPPED THE WX (FOG) AT 1200' MSL. AN EMER WAS DECLARED AN THE FLT PROCEEDED TO MCO, WHICH WAS VMC, AS FILED. THE ALT WAS MAINTAINED VISLY AND BACKED UP WITH THE RADIO ALTIMETER. AIRSPD WAS FLOWN AS PRESENTED BY THE INDICATOR. ATC PROVIDED GND SPD READOUTS FOR AIRSPD CTL AS THE ACFT APCHED MCO. AN UNEVENTFUL ILS APCH WITH NORMAL FLAP 30 DEG LNDG WERE MADE ON RWY 35. DURING THE FLT THE LIMITING DESIGN SPD OF THE FLAPS AND LEADING EDGE DEVICES WAS EXCEEDED DUE TO THE ACTUAL SPD OF THE ACFT BEING MUCH GREATER THAN WAS INDICATED. ON FLT TERMINATION AT MCO IT WAS DISCOVERED THAT THE STATIC PORTS HAD BEEN COVERED WHILE THE ACFT WAS WASHED AND THE TAPE WAS NOT REMOVED WHEN THE ACFT WAS RETURNED TO THE LINE.
