CallAir Model A
1940 utility aircraft family by Call Aircraft in the United States
The Call-Air Model A is an American two- to three-seat utility aircraft designed by the Call brothers and built by the Call Aircraft Company, later developed into a successful line of agricultural aircraft.
Design and development
The Model A was designed by the Call family, who were Wyoming ranchers. The aircraft was ready to be produced in 1940 but the start of World War II delayed the start of production to 1946. The family had formed the Call Aircraft Company (known as Call-Air) to produce the aircraft. The prototype Model A was powered by a Continental A-80 engine but was redesignated the Model A-1 when re-engined with an Avco Lycoming O-235-A engine. A United States type certificate was awarded in July 1944 and the production model was designated the Model A-2. The Model A-2 was a two-seat braced low-wing monoplane with fabric-covered wooden wings and fabric-covered welded steel tube. It had a fixed tailwheel landing gear. Further models were introduced with different engines. Examples of the three-seat A-4 were converted for agricultural use followed by a new-build agricultural version the A-5.

Why this record matters
“CallAir Model A” is worth following because a concise public description often conceals a longer documentary argument. Here, CallAir, Model and utility provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q2934060. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1940, 1946 and 1944.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
