Schleicher ASK 14
|Manufacturer||Alexander Schleicher GmbH & Co|
|Developed from||Schleicher Ka 6E|
The aircraft is often referred to as the Schleicher AS-K 14 or the Schleicher ASK-14, the AS for Alexander Schleicher and the K for Kaiser. The US Federal Aviation Administration designates the aircraft as the Schleicher ASW-14, while Transport Canada and the United Kingdom Civil Aviation Authority call it the Schleicher ASK 14.
Design and development
The ASK 14 was developed as a low-wing motorized version of the Schleicher Ka 6E. The powerplant is a 19 kW (25 hp) Hirth F10 K19 two-cylinder, two-stroke engine, made by Hirth and driving a fully feathering propeller.
The aircraft is built from wood and covered with doped aircraft fabric covering. The 14.4 m (47.2 ft) span wing employs a NACA 63-618 airfoil at the wing root transitioning to a NACA 63-615 section at the wing tip and features spoilers. The monowheel landing gear is retractable. The cockpit is covered by a bubble canopy that gives all-around visibility.
The ASK 14 was never type certified and aircraft registered in the United States were in the Experimental - Racing/Exhibition category. ASW 14s in Canada are in the category CAR Standard 507.03(5)(a) Aircraft Held a Flight Permit - Private Aircraft prior 01/89. Those in the UK have an EASA Certificate of Airworthiness.
