Mosquito Restoration on Track for Spring Flight
KA114 would languish and decay on that farm until 1978 when it was transferred to the Canadian Museum of Flight and Transport (CMFT) by one of its founders, Ed Zaleski.
Moving the Mosquito to the museum was a distinct challenge as time had ravaged the wooden airframe. The forward section of the fuselage disintegrated while the rest of it broke in two as it was being loaded for transport. The aircraft was also missing both engines and parts of the landing gear, but the majority of the wing and many other parts had fared much better over the years.
The Mosquito first saw combat in September 1942 and served in many roles as a medium bomber, night fighter, reconnaissance aircraft, in tactical strike missions, and in anti-submarine warfare. The mostly wooden airframe made it light and fast, reaching speeds of 390 mph. The Mosquito was so effective, especially in night raids, that the commander of the Luftwaffe, Herman Goering, often expressed frustration at the vexing problems the aircraft known as the “Timber Terror” caused. Special squadrons were created to confront the Mosquito but found little success. Goering even lamented that, despite a perceived availability of large metal reserves available to the British, they chose to create a wooden aircraft, while Germany was short on raw materials but could not effectively innovate in this area.
It would take some innovation to restore KA114 as well. The remains of the aircraft stayed at the CMFT until it was purchased by Jerry Yagen, who operates the Fighter Factory, which is the restoration arm of the Aviation Institute of Maintenance, in Virginia Beach, Virginia. As Ed Zaleski found, moving the pieces of the aircraft proved challenging as they used a chainsaw to trim 4 feet off the wing to fit it in a shipping container for the journey to a restoration center in New Zealand.
Original wood parts cannot be restored like metal can; therefore, Glyn Powell, of Auckland, New Zealand, was enlisted to create new fuselage, wings, and tail sections. Wood made the Mosquito fast and formidable, but it was challenging to make in large pieces. Powell discovered why Canadian manufacturers used concrete molds to shape the fuselage: Larger wood molds (36 feet for the Mosquito) tend to change shape based on daily atmospheric conditions. Powell employed a top boat builder to assist with creating the molds and applied a “modern” epoxy instead of glue in joining many of the pieces. Otherwise, Powell says that he is “absolutely faithful to the original drawings and specifications.”

All the parts were shipped to Ardmore Airfield in South Auckland, New Zealand, where AvSpecss, which has a wide range of expertise rebuilding vintage and warbird aircraft, is based. AvSpecss’ previous work for the Fighter Factory includes the restoration of a Dragon Rapide, which won Best Warbird Transport at AirVenture 2010.
Jerry Yagen says that, while parts were hard to find, at this stage only engine cowlings and a prop spinner are left to track down. One of the difficult parts of the restoration was grounding the metal parts on a wooden aircraft. The original manufacturers used flat strips of copper to ground some of the remote parts of the aircraft, such as the ailerons. Yagen says making sure all the parts were tied into the grounding system was a unique challenge.
AvSpecss maintains a building blog here.
KA114 is expected to fly by Easter (2011), and if all goes well will make its debut in the Ardmore Air Show. Yagen would next like to send the Mosquito on a summer tour of British air shows as a salute to the Mosquito’s English heritage. By fall the aircraft will return to North America permanently and be based at the Military Aviation Museum in Virginia Beach.
