FAQs
What is the T3 tailwheel suspension system and how does it work?
The T3 is a coil-over style tail suspension system that replaces the OEM leaf spring with one or two coil springs and an oil shock working together. The coil springs absorb the initial landing impact while the shock controls rebound, reducing bounce and fuselage stress. The result is improved pilot control during landing rollout, takeoff, and taxi across all surface types.
Does the T3 suspension use the existing fuselage attachment points?
Yes. All T3 systems are designed as bolt-on replacements using the existing factory attachment points. No airframe modifications are required.
Does installing a T3 suspension require a weight and balance revision?
Yes. Weight and balance must be updated after installation and appropriate logbook and maintenance record entries are required.
How do I know which T3 suspension to buy for my aircraft?
Refer to the T3 Approved Model List (ABI-DST3-AML) for certified aircraft applications. For experimental aircraft, select based on your aircraft make and model, gross weight, and whether you need FAA STC approval. Contact Airframes Alaska directly if your aircraft is not listed.
Where can I get replacement parts or technical support for an ABI T3 suspension?
Contact Airframes Alaska / ABI LLC directly. Phone: 907-331-4480. Website: www.airframesalaska.com. Address: 81 E. Commercial Drive, Palmer, AK 99645.
Are there airworthiness limitations associated with the T3 suspension systems?
No. The certified T3 systems (ABI-51343 and ABI-51525) have no new or additional airworthiness limitations beyond what is required under FAR 43.16 and 91.403.
