The Schleicher ASK 14 is a West German low-wing, single-seat motor glider that was designed by Rudolf Kaiser and produced by Alexander Schleicher GmbH & Co. [1] [2]

Contents

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 ASK-14, while Transport Canada and the United Kingdom Civil Aviation Authority call it the Schleicher ASK 14. [1] [2] [3] [4] [5]

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 four-cylinder, two-stroke engine, made by Hirth and driving a fully feathering propeller. [1] [2]

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. [1] [2]

Due to its Ka 6E heritage the handling of the ASK 14 was described by Soaring Magazine in 1983 as "superb". [2]

The ASK 14 was never type certified and aircraft registered in the United States were in the Experimental - Racing/Exhibition category. ASK 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. [3] [4] [5]

Operational history

ASK 14s finished second, third and fourth in the single-place class at the first international motorglider competition, that was held at Burg Feuerstein, West Germany in 1970. [1]

In 1971 former Soaring Magazine editor Bennett Rogers set the first United States motorgliding record in an ASK 14, flying 330.5 km (205 mi) out-and-return from Rosamond, California, US. [2]

In July 2011 there were still eight ASK 14s registered with the FAA in the US, two with the UK Civil Aviation Authority and one registered with Transport Canada. [3] [4] [5]
