Earl,
How can polyethylene tubing hold the curve to keep the airspeed probe cylinder correctly aligned? Ed the aluminum tubing that runs from back of airspeed indicator out into wing can that be replaced with polyethylene tubing legally ? <http://geo.yahoo.com/serv?s=97476590/grpId=19286938/grpspId=1705340085/msgI d=7253/stime=1230940352>
