Waterhouse Roamair NC990

Designed by William Waterhouse and Lloyd Royer, the 1925 Roamair / Romair 2-3 place open cockpit biplane was built with various engines.

Both spellings were chosen, but Royer’s steadfast claim of “Romair” is tempered by some photos showing “Roamair” on the tail.

Waterhouse Roamair N2910

Five were built:
NC990 c/n 18 with Wright J-5, to Pacific Coast Air Service, rebuilt in 1931 as a crop duster with 220hp Wright J-6, and re-registered NR12785

Waterhouse was a respected structural analyst and engineer who “… undertook an assignment late in 1927 for the Mexican Government, which wanted to [produce] its own aircraft. Two monoplanes were constructed by Tijuana Aircraft Co, headed by Gov Abelardo Rodriquez of Baja California. Plans were furnished by the Mexican War Department and adapted by Waterhouse. The planes, completed in early 1928.

The 1926 Cruzair two place cabin high wing monoplane was designed by William Waterhouse and built with assistance from Ryan Mechanics Monoplane Co.

Partial plans reportedly were sold to T Claude Ryan as a project for the Mahoney-Ryan Flight School and were responsible for the Ryan M-1 Brougham design.

N2138 was bought from Pacific Air Transport by motion picture stunt pilot Dick Grace and extensively modified for his abortive Hawaii-San Francisco transpacific attempt on 4 July 1927. It was shipped back to California and rebuilt as Ryan Mechanics Co Miss Southern California for competitions.

Wassmer Aviation Ltd., founded in 2007, is a small aircraft design and engineering company based in Wohlen, Switzerland. The main purpose of the company is to support the development of the MSW Votec 252T/352T aerobatic training aircraft. The entirely new high-performance aerobatic trainer in side-by-side configuration was designed by Max Vogelsang on the basis of the MSW Votec 322.

It is a main target to achieve, together with MSW Aviation AG, the EASA certification for the Votec 252-T aerobatic trainer and to offer it to the interested clientele.

In addition, Wassmer Aviation support several other experimental aircraft projects.

Wassmer Aviation also keep historical aircraft up in the air. Their ex Swiss Airforce Pilatus P-3/05 is in flying condition and the renovation of a very rare ex Swiss Airforce North American AT-16 (ex U-323) was under way in 2013.

Wassmer WA-50 / WA-51 Pacific / WA-52 Europa / WA-54 Atlantic

TerryLeave a comment

Wassmer started development of an all plastics lightplane in 1962 with the object of producing a comparatively cheap but durable and easily maintained type for ihe private owner.

The WA-50 prototype flew in March 1966 as a four-seater powered by the 112-kW (150-hp) 0-320 engine. One of the first aircraft extensively constructed from glassfibre, production began in the form of the WA-51 Pacific with fixed tricycle landing gear and the 112-kW (150-hp) O-320-E2A engine, though a companion model was produced as the WA-52 Europa with the 119-kW (160-hp) IO-320-B1A driving a variable-pitch propeller. As these two initial models went out of production in 1973 the company introduced the WA-54 Atlantic with the 134-kW (180-hp) O-360-A engine, more baggage volume, revisions to the landing gear, and other modifications.

WA-54 Atlantic

Wassmer went into liquidation in 1977, and by that time sales of the WA-50 series totalled 190 aircraft.
