preflight....wing struts?
How do I actually check these? Ive always just grabbed them and shook really hard. If I hear no rattle or feel no give I figure they are ok. Is this correct? How do you check your struts? And is it true that if the nose wheel strut is more than 3 fingers extended its ok? I know from line that if the scissors are pretty much bottomed out its a problem...but whats the general rule on that? Thanks!
