Howard DGA-15P Landing Gear Shock Strut Spring (Note: This is drawing LG44J, which is not the standard spring, but the spring required when using a prop with 6101-12 or 6101-14 blades per item 101 (d) in the DGA-15 Type Certificate. It's a little longer [2 inches] than the standard spring and made from a different material.) Vintage Textbooks for the Vintage Aircraft Restorer (article by John A. Eney)
