Hi,
I think you can still get Main landing gear seal that mounts at the top of the strut at Solberg Aviation,
www.solbergairport.com or (908) 534-4000 ask for Suzy. They also have the main landing gear boots. The set that I picked up were cheap but in really bad condition, they could only be used a paterns. Just have a local upolstery shop build them up, they were originaly a black canvas material.
There is a SB for checking the wear of the main landing gear bushings and several SB for the tail strut. My company rebuilds Fairchild tail struts for the PT series and F-24. For more information on that, please contact me at
N9UNS@AOL.COM.
There are only two AD's on the Ranger engine and I think you can find them at FAA.GOV or through T-data.
Hopes this helps.
Bill
