Note: These parts are for Cardinals production serial number 17701731 and up.  Earlier serial number airframes require a longer part.  If you have one of the early Cardinals and would like a set of these replacements, please contact me and I'll see what I can do.

If you want certified parts, may I suggest Yingling Aviation: DETECTOR 1221201-3 (

Price: $100.00 per pair (Free shipping to the continental United States.  Please contact me for shipping to other locations.)

P.S. Because the 337 has a very similar wing to the Cardinal, it's possible that these parts will also fit Cessna Skymasters as a replacement for part number 1520008-15.  Feel free to order a set if you want to give it a try.  I'll promptly return your purhcase price and pay return postage if they don't fit.

Return policy: If returned unmodified within 180 days from your order, I will refund 100% of your purchase price.  If you want to return the parts after 180 days, please contact me.

How to pay: PayPal (username "") or check payable to: Matt Parry, 531 Geranium Pl, Oxnard, CA 93036
