Ryan NYP Split-Axle Landing Gear and Bungee Shock Assembly (View 2) (May 1927)

Low ground-level view of the right split-axle landing gear, bungee shock fairing boot, and fabric wheel cover. — Ryan NYP Split-Axle Landing Gear and Bungee Shock Assembly (View 2) (May 1927) · Donald A. Hall Estate Collection

An archival engineering flightline photograph detailing the right landing gear assembly of the Ryan NYP Spirit of St. Louis on Dutch Flats. The exposure highlights the heavy-duty chrome-molybdenum split-axle truss, the vertical shock boot enclosing multiple strands of pretensioned industrial-grade bungee cords, and the fabric-doped wheel fairing. Engineered by Donald A. Hall Sr. to withstand the 5,200-pound maximum overload takeoff weight, the gear absorbed intense ground shock and transferred dynamic landing loads safely into reinforced lower longeron nodes.
