- A national military or armed force has aircraft that are based on a civilian model. Persons who analyze aircraft safety data may wish to review reports of military and non-military operations of the aircraft model. In addition, over time former military aircraft enter civilian aircraft registries and accident/incident databases. For example the Master Model DOUGLAS-DC3 applies to the civilian DOUGLAS-DC3 as well as the military versions: DOUGLAS-C47 and DOUGLAS-R4D.
- Aircraft manufacturers purchase the rights to build a particular aircraft model and the aircraft manufacturer designates a new aircraft model. Without performing research the relationship between two related models may not be obvious. For example Ted Smith Aerostar Corp. designed the SMITH-AEROSTAR 600 and later sold the aircraft to Piper Aircraft Corp., which used the designation PIPER-PA60. These rights for this particular aircraft are now held by Aerostar Aircraft Corp., which also uses the “AEROSTAR” designation. The table below lists the aircraft models and series with the master model SMITH-AEROSTAR600.
- An aircraft manufacturer may build an aircraft under license to another manufacturer. An aircraft built under license would maintain the master model used by the manufacturer that holds the design rights. As an example, the Master Model CASA-212 applies to aircraft built by CASA and IPTN.
|ORG COMMON NAME||AIRCRAFT MAKE||AIRCRAFT MODEL||AIRCRAFT SERIES|
|TED SMITH||SMITH||AEROSTAR600||NO SERIES EXISTS|
|TED SMITH||SMITH||AEROSTAR601||UNDESIGNATED SERIES|

By definition, the aircraft make is the name assigned to the aircraft by the manufacturer when each aircraft was produced. In most cases aircraft make is the organisation common name of the aircraft manufacturer. If the organisation that holds rights to an aircraft design permits another organisation to build that aircraft, in most cases the aircraft make would be the aircraft name assigned by the organisation that holds rights to an aircraft design. If an aircraft manufacturer is amateur construction, in most cases the aircraft make would be the name of the organisation responsible for design.
As an example, the Cessna Aircraft Co., an aircraft manufacturer, builds aircraft that are assigned the name CESSNA, an aircraft make. In addition, Reims Aviation S.A. and Direccion Nacional de Investigaciones y Fabricaciones Aeronauticasan, aircraft manufacturers, build aircraft known as CESSNA, an aircraft make. The table below lists the different manufacturers of the CESSNA-182.

Aircraft Manufacturer: British Aerospace (now BAE Systems)
Aircraft Makes: BEECH, BAE, BAC, HAWKER SIDDELEY, and PERCIVAL
In another example, an aircraft manufacturer that build aircraft under license could have more than one aircraft make. For example, Kawasaki Jukogyo Kabushiki Kaisha built aircraft for BELL, HUGHES, and MBB.
- AVIONS ROBIN
- AMATEUR CONSTRUCTION
To alleviate this issue, the sub-team created the term “Undesignated Series” for aircraft where one series of an aircraft model, typically the earliest one, is known by the model designation (for example, Cessna-172).
By creating the term “Undesignated Series”
- CESSNA-172 applies to (1) a grouping of all aircraft with the same aircraft model (for example, CESSNA-172-A, CESSNA-172-B, et al.
- CESSNA-172-UNDESIGNATED SERIES applies to (2) the aircraft designator for a CESSNA-172 aircraft model without a series.
For example a SOCATA-TB20 cannot be described at a lower level.
