Yes. The design allows a metal rod to be connected to the lever, enabling rear passengers to apply the brake when needed.
Installation is straightforward: the unit connects from the master cylinder to the caliper. As a direct replacement, it requires no airframe modifications.
To set the brake, depress the brake pedals firmly, engage the gold lever, and release. This holds pressure in the line to keep the aircraft secured. The brake connects from the master cylinder to the caliper.
Two brakes are required per aircraft — one for each pedal. A single brake is available for individual replacement, or a full set can be purchased to replace both.
Yes. AF51705 holds FAA Parts Manufacturer Approval (PMA No. PQ3848CE) under 14 CFR § 21.303, approved as a replacement for the Scott article 492-023 based on test and computation data (Drawing No. AF51705).
AF51705 is the Airframes Alaska Parking Brake assembly. It is a PMA-approved (Parts Manufacturer Approval) direct replacement for the Scott 4500A-1 parking brake, engineered to secure the aircraft on the ground and prevent unintended movement, particularly in windy conditions or on rough terrain.
AF51705 features a hard anodized finish that provides superior corrosion resistance and increased durability compared with bare, unprotected metal alternatives — an advantage in harsh weather and backcountry environments.
It is a direct replacement for the original Scott 4500A-1 parking brake. Installation and functionality match the original unit, so no modification of the aircraft is required.
The parking brake is mounted beneath the front seat, positioned for easy access by the pilot during ground operations.
It is eligible for the Piper PA-18 (Super Cub) series, PA-19, and PA-20 through PA-22 models, including the various PA-18/PA-19 sub-variants covered under the FAA PMA approval.
