Overall this is related to the AD 77.13.01, Part A. Specifically I have removed this AD service from the list of Migrant Worker services; it has been just too involved for me to deal with in a remote location without the proper equipment that is required to perform this service.

However I’m still developing the components program; it’s going to be quite an involved project but may also be a real time-saver if you do not have an experienced shop available to perform this service. This service will have the option of cadmium plated steel components, see below. Stay tuned or call for an update.

Read below for a description of which airframes this component fits. I bought all of Piper’s inventory; if you need a new one call me. See also the parts link. No used serviceable available at this time.

Main Gear Drag Link – A.K.A. Down-Lock Link

This component fits the main landing gear on all Piper Comanche 180 and 250 and 260 models EXCEPT the 260C. In addition it does not fit the 400 Comanche or Twin Comanche models; those models employ a larger link with 5/8”-18 threads. The basic part number for this drag link is 20768-002 which is the bare link without bracket or lubricator fitting. I have added a new lubricator fitting which will work with the 180 & 250, but not for the 260 – use your old 260 grease fitting. The ASSEMBLIES P/N’s are 20768-000 [Piper retail $875.20] and 20768-001 [Piper retail $699.74] for the 180 and 250, and 24911-000 [Piper NLA] for the 260. These parts are new from Piper, see the photo of the inspection tag, but they come with no paperwork except that label. Here is an opportunity to purchase them new; only a few remaining in stock. You transfer your old bracket to this new part, or as an option I can provide these as an assembly including the bracket freshly cadmium plated, EXCHANGE ONLY. Call for current pricing.

The Piper AD 77-13-21 Part A [the infamous 1000-hour landing gear AD] inspection includes this part. The threads wear and need to be checked with a thread ring gauge as outlined in SL-782B required by AD 77-13-21. The inspection criteria are spelled out in SL-782B and concerns those threads and the bore; I have inspected them per the SL and they pass as would be expected.

I also have cadmium plated serviceable links for the heavy airframes; 260C P/N 25046-000, 400 P/N 22577-000, and twins P/N 22577-000 and 25046-000. As of 02/01/2046 I have 2 of these links remaining; when they’re gone that’s it until owner-produced.

By popular request below is shown a modified insert from a Piper landing gear assembly drawing showing the order of parts in this area. The beveled washers referenced are not used on the 260C, 400, and twin Comanche; those are non-beveled and a different part number. The notes in RED are mine.

A complete compliment of cadmium plated exchange steel components related to the landing gear is usually available; the above is just a sample. This should be considered when refurbishing the wheel wells or other opportunity.

Here is a sketch I’m using for reference; it shows the roll pin and drive screw part numbers, and nose gear springs’ new part number. I wish this was a better scanned image for you; I can’t improve its quality.
