Former Aircraft Hangar Approximately 200 Metres South East Of Headley Hall Farm

The former aircraft hangar, located approximately 200 metres southeast of Headley Hall Farm, was built in 1916 for the Royal Flying Corps and is now used as a barn. This slightly altered structure features timber construction with wall panels said to be made of steel and concrete laminate. It has a segmental roof covered with felt. The large rectangular building measures approximately 50 by 30 metres and is oriented on an east-west axis, with single-storey offices attached to the north side.

The hangar includes laminated timber wall posts supported by external buttresses of the same material. Horizontal ties pass through the wall at mid-level, with raked ties extending to the roof trusses. Continuous small-paned glazing is situated between these ties. There are full-height sliding doors at both ends, which have been altered and either replaced or faced with corrugated iron sheeting. The segmental gable features vertical windows and a central ventilator. The offices on the north side are of similar construction.

Inside, the hangar has laminated timber roof trusses made of segmental latticed girder construction, with the outer ends boarded. These trusses are linked by a pair of purlins mounted on the tie-beams, which support closely spaced purlins and diagonally boarded cladding, believed to be cross-diagonal laminate. Some original wall lettering can still be seen in the bays.

Historically, this hangar is the only surviving building of No 38 Training Depot Station (TDS) in Tadcaster, which opened in the spring of 1916 with the arrival of B Flight of 33 Squadron and later 46 Reserve Squadron. It was initially used for air defense of the Leeds and Sheffield area and was part of TDS, which were typically the largest First World War aerodromes serving as bases for squadrons mobilizing for overseas service. The site closed in June 1919 and was subsequently used as an aircraft store before being sold. This hangar is a good example of its type and date, sharing construction features with buildings at the RAF Museum in Hendon and Duxford Airfield in Cambridgeshire.
