Made by a pilot for pilots, the Vintage Beechcraft Bonanza P/N 35-524585-21 Control Arm Cover is a dimensional reproduction of the distinctive center cover used in the classic Bonanza throw-over control yoke. Beechcraft parts documentation identifies P/N 35-524585-21 as “COVER,” Figure 61, Item 25, with applicability to aircraft S/N D-4866 through D-8335.

Reproduced from an OEM master in diameter and weighing less than 8 grams, this three-color reproduction recreates the original black face with raised white WING DOWN directional markings, centerline indication, LT and RT markings, and the distinctive Beech emblem and perimeter finished in a chrome-style appearance.

Unlike a flat printed decal, the individual graphic elements are incorporated into the dimensional construction of the cover. The completed face is clear encapsulated, adding depth to the markings while providing a smooth, protected finished surface appropriate to the highly visible center of the control yoke.

The cover installs directly into the original throw-over yoke assembly and requires no adhesive or backing. It is retained in the yoke by the original spring retaining arrangement, preserving the installation method and appearance of the original Beechcraft component.

Designed and manufactured in the USA by Swearingen 3D Works, each cover is individually manufactured, assembled, finished, and encapsulated. For the vintage Bonanza owner restoring an original cockpit, P/N 35-524585-21 brings back one of those small details sitting directly in the pilot’s field of view—the kind of detail that makes the cockpit look complete again.
