KR> Airspeed indicator

[bjoenunley]

My airspeed indicator is suddenly inaccurate. ?It reads 32 mph rather than 55 
mph. ?What would cause a sudden change? ?I have found no blockage in my ram air 
or static lines. ?The pitot tube alignment is normal. ?I haven't added a static 
drain point yet. ?Can the instrument have gone bad and can I fix it? ?What more 
can I do?Thank you.
