Lang Tailwheel D-501A

Part# 06-00398

The Lang Model D-501-A Tailwheel is full swivel, fully auto- matic and steerable. It's impossible to throw the Lang tail- wheel into full swivel unintentionally regardless of rough field conditions or cross winds. This tailwheel will not lock in any position except steerable, but releases easily when plane is pushed sideways or backwards by hand or when maneuvering plane on ground using brakes.
The Lang tailwheel fits both 1-1/4" and 1-1/2" leaf springs. Drop forged, heat-treated 4130 steel fork of single arm type. A cast aluminum wheel is grease packed for 100 hrs service. The 6x2.00 solid rubber tire has interior wire reinforcement for added strength. Manufactured by ACS Products Co. under FAA-PMA. All replacement parts available. The Lang tailwheel is FAA-approved for installa- tion on many light aircraft including Aeronca 7AC, Piper J-3 and PA-12, Cessna 140, Luscombe and Taylorcraft. Comparable to Scott Model 2000. Wt. 6 Lbs.

Works very well, I like it much better than the Scott tailwheel it replaced on my Taylorcraft.

Perfect for my ‘46 J-3 and just required a logbook entry from my A&P.

I have been running the Lang D-501-A on my Luscombe for over 900 hours. In my opinion an excellent tailwheel, a great improvement over the Maule I ran originally and better than the Scott 2000 type. Only maintenance other than grease and tires is occasional replacement of cam washer and locking pin.
