CF-ARQ – ROAD TO RESTORATION
CF-ARQ was purchased as a kit and built by J.A. (Art) Brazier in Regina in 1931. It passed through several hands until it was re-purchased and partially rebuilt by Art Brazier and other employees of McDonald Bros. Aircraft including Victor Davey and Paul Latocki. The Froebe Brothers of Homewood purchased it and refinished the rebuild, but it was then damaged in an accident. The aircraft was eventually acquired by Doug Emberley. He donated it to the Western Canada Aviation Museum in 1990.
The restoration of CF-ARQ began in September 2005. The restored configuration is being done to the previous reconstruction work of the original CF-ARQ. The finished colours will be red and white.
PRESERVATION AND RESTORATION
Particular care has been taken to provide the best long-term protection against deterioration or corrosion while preserving the original features and details of the aircraft. For example, parts are not cad-plated if the originals were primed and painted.
Original parts are being restored when possible, but if they can’t be restored to satisfactory standards, they are used as a source of information for the manufacture of replacements and then retained for posterity. Drawings are on file for the Heath Parasol, but since the aircraft was ‘homebuilt’, many alterations were made to suit the builder’s fancy.
Green primer is being used on metal parts where required in place of zinc chromate which is no longer available or permissible. Probond glue is used on all wood jointing. Only ‘AN’ nuts and bolts are being used rather than the more modern NAS or MS types. Likewise, only brass nails are used, so as to be authentic to the era of the aircraft. Aircraft grade cotton fabric and tapes will be used, if available, and applied to all applicable units in the best workmanship manner of the period. Doping will be done to provide an acceptable and attractive finish.
The fuselage consists of a welded steel tubular frame whcih arrived in fairly good condition. Discrepancies are being rectified and the steel frame painted gloss black. The wood stringers were sanded and varnished. The detachable steel tubular engine mount is bolted to the forward (four) corners of the fuselage frame. The condition of this unit is good, but requires modification to accommodate the three points mounting of the Aeronca E10-A engine.
The cockpit contains the control stick, rudder pedals, brake pedals, plywood instrument panel (less instruments), seat support structure integral with the welded fuselage and plywood floorboards. This area required cleaning, painting, securing of the floorboards, making a replacement seat and determining the instrument panel layout.
The wings are constructed of wooden front and rear spars, wooden ribs, four steel tie wire braced bays, steel tubular wing tips and steel attaching fittings. Bay brace wires have ferrules on one end and are tensioned with turnbuckles. Trailing edges are of aluminum ‘V’ channel form. Compression members are 5/8” square tapered wood batons. There are seven steel channel false ribs at the wing tips. One on the left-hand wing is broken and requires repairs. The finish of the wooden parts appears to be a type of varnish, but boiled linseed oil is specified on some drawings. We will be using Varathane water-based varnish for everything, as it is more long lasting than linseed oil. New nose ribs are being made and installed and loose gussets reglued.
ONLY 24 BUILT IN CANADA
Since only 24 Heath Parasols were ever registered in Canada, it represents an important part of aviation history. Much progress has been made, but there is still lots of work to do!
