    What size safety wire is needed for working on a PA-18-150?

    What safety wire sizes are used on a PA-18-150? I would like to have the proper sizes available for maintenance and for any work that needs to be done on it at the hangar (annual, repairs, etc...)

    0.02"
    0.021"
    0.025"
    0.032"
    0.041"

    I typically use .025 for most everything except turnbuckles and prop bolts which require .041
    After Monday and Tuesday, even the calendar says WTF !

    Thanks,

    I was guessing that .032" would have been common on a Cub.

    I use .032 for most applications, except as noted by PerryB. .041 for prop bolts and primary control system turnbuckles.

    .041 is most common I need.... I have the others, but rarely needed (like I still own the original other size rolls decades later, never used up..)

    Use the thickest wire that will easily fit in the hole. Usually .032" and .041" Smaller sizes such as .025" are typically used on small screws and electrical connectors.

    I'll have to go back and look, maybe .032 is my small wire.

    Yep .041" on prop bolts and turn buckles and .032" on everything else. I use .020" to hold Adel clamps together while I get the fastener in if I can't get my clamping tool in there.

    Try AC43:13 for legal technical info as well, though 032 except prop is right.

    I agree, except that, if you think about it, any bolt that backs out with enough rotational force to shear .032 is going to shear .041 as well. You know that battleship-sized cotter key that holds the wheel nut? Imagine what it would take to shear that thing, and then think: would you rather the axle nut come off, or that seized bearing to melt your axle?
