The HP-14 is a Richard Schreder-designed all-metal glider aircraft that was offered as a kit for homebuilding during the 1960s and 1970s.

[1] It was originally developed by retrofitting improved wings to the fuselage and tail of the HP-13, and first flew in 1966.

[2] Schreder won the 1966 US national soaring championship in the prototype HP-14.

[3] Development of the HP-14 was carried out by several parties but the biggest modifications to the design were carried out by Slingsby Aviation at Kirkbymoorside, North Yorkshire, England, where a 20-metre wing was fitted on the prototype HP-14C, along with an enlarged V-tail.

Slingsby production and sales were hampered by certification problems, particularly with flap actuation at high speed, and the disastrous fire at Kirbymoorside on 18 November 1968.
