M20F-1968 Posted January 2, 2021 Report Posted January 2, 2021 I have the 4" Specmat Technologies Discharge Wicks on my airplane. I am not at the hangar. Can anyone get me the proper part number? Are there any others that would work. I changing shirts at the hanger, put my arm in a sleeve, mildly hit the base of the wick on the rudder and it broke in half in a millisecond. Really do not want to pay $55 bucks for this problem. John Breda
M20F-1968 Posted January 2, 2021 Author Report Posted January 2, 2021 Well I have a partial answer: Specmat 10-900-59/1 and 10-900-60/1 it seems will both work. The 60/1 I think is the 4" version. There is also a TSO DD-1W which apparently is a replacement, but I have seen it listed for non-certified aircraft. Anyone know more than that to advise the best replacement for the least money?

PT20J Posted January 2, 2021 Report Posted January 2, 2021 I bought some TCO DD-1(W) from SkyGeek but returned them as they were 6” long not 4. Couldn’t find a retail source for the Specmats which are on my airplane. Ended up just buying them from LASAR. Yeah, they’re expensive. I remove them when the plane goes in a shop for maintenance. I also check the torque on them during preflight ever since one went missing during a flight. Skip
M20S Driver Posted January 2, 2021 Report Posted January 2, 2021 I accidentally broke one today. I found the 60/1 on ebay. I have one spare already so feel free to outbid me if you need to get them. my maximum bid currently is $66 for two but the current bid is $61. They list $5.00 for shipping.
JLG Posted June 26, 2025 Report Posted June 26, 2025 Did anyone find a replacement the Part Number is 10-900-60?
Marc_B Posted June 26, 2025 Report Posted June 26, 2025 @JLG best deal I've found https://www.scross.com/store/part-number?10-900-60-1
Mark89114 Posted June 26, 2025 Report Posted June 26, 2025 I just had one replaced, that price seems about right. My buddy had to have one replaced as well, he may or may not have used the experimental version.
TheStig Posted yesterday at 01:45 AM Report Posted yesterday at 01:45 AM Does anyone know where to find the trailing retainer they go into. On one of mine the the threaded part of the the static wick broke off in the retainer. I can find a Granger retainer but it is different. The original retainers on the Mooney Ovation 1s look like an aluminum tube the was flattened on one end, bent slightly, filed on one side and then threaded for the 10-900-60-1 HR Smith (Specmat) wicks.
Marc_B Posted yesterday at 02:25 AM Report Posted yesterday at 02:25 AM @TheStigThe base you’re looking for is 10-900-85 I believe. Looks like Lasar might have some. https://lasar.com/pitot-static-system/static-wick-base-10-900-85
PT20J Posted yesterday at 02:59 AM Report Posted yesterday at 02:59 AM I'd try drilling it out and and re-tapping.
