Glasair III, Nose Gear Drag Link Upgrade

Hansen Aerospace’s 4140N steel, G3-DL5 Nose Gear Drag Link, is a drop in replacement for the standard factory provided aluminum linkage. Assembly components have been upgraded to aerospace grade MilSpec bushings and spherical bearings with increased load ratings.

Objectives for this part were to provide increased strength over the factory aluminum part, improved safety, longevity, and reliability for what has historically been the weakest link in the retraction mechanism, and continues to be responsible for numerous nose gear failures. Unlike the aluminum factory drag links, our drag links are interchangeable and can be used on either side of the nose gear strut.

The drag link replacement is available in two versions.

  • G3-DL5A, Yellow Cadmium Plating -
  • G3-DL5B, Black Cadmium Plating -

Black Cadmium Plating has no equal when it comes to corrosion prevention and is used extensively on steel parts repeatedly or continuously submerged in salt water.

If you operate in the winter, on runways treated with salt, urea, sodium acetate, sodium formate, potassium formate, or potassium acetate, then the black cadmium may be the best choice to reduce the possibility for corrosion. This also applies to aircraft based within 5 to 10 miles of coastlines and where onshore winds with salt mist may be a factor. For all other areas of the country the standard yellow cadmium plating is sufficient to protect this higher strength steel drag link.

This is the third and final production run of this drag link. When these links have been sold there will be two types of Glasair IIIs, those with the upgraded nose gear drag link modification, and those without. We have already seen several G3 aircraft-for-sale postings which include this nose gear upgrade in their list of safety improvements.

Support Information

The downloadable White Paper link on this page outlines the history behind the G3 nose gear drag link, factory design philosophy, historical failures of the factory aluminum part, and some installation considerations. Additional files are excerpts from the G3 factory installation manual regarding installation, rigging, and operation of the nose gear drag link.

Some Kinds Words from Some of our Clients

"After finding a crack in my nose gear drag brace it’s reassuring to know my new GDL5 brace gives me a substantially improved safety margin. I am now looking forward to the external power alternative Hansen Aerospace has hinted as coming next in the development pipeline."
