ABOUT THIS COLLECTION
- Several different scanners were used during the project to scan the SACs held by the Aviation History Branch. Consequently, there will be some variation in the quality of the scans.
- Blank pages in the SACs were not scanned, hence, when you see a page 6 but there are only 5 pages in the document that means there was a blank page that was not scanned. This was done to reduce the size of the scanned document.
- Some SACs had supplemental pages added at a later date. When supplemental pages were available they were scanned and added to the document.
Some of the SACs may include pages for the aircraft with different dates. However, most of the SACs only include a copy of the latest publication date for the SAC held in the collection.
- The SACs scanned only include those with 3-view drawings. The format for Navy SACs has changed over the years and 3-view drawings were not included in SACs until the 1940s.
- This collection of scanned SACs is all that was available in the Aviation History Branch archives. A complete collection would require consolidation of the SACs held by the Naval Air System Command and those in the Bureau of Aeronautics Collection (Record Group 72) held by the National Archives.
- Sometime in the future the Aviation History Branch will scan the other SACs in its collection that do not have 3-view drawings. Unfortunately, those records do not lend themselves to easy scanning and the format does not provide as much information.
- Each SAC designation in the index is the same as the designation listed on the front of the SAC. There will be some aircraft that have two separate SAC designations because of the change in the Navy's aircraft designation system in 1962. As an example, you will find a SAC designation for an AD-7 and an A-1J. They are the same aircraft but the AD-7 is the pre-1962 designation and the A-1J is the post 1962 designation.
- Some SACs have been included in this CD-ROM collection because they were under Navy Contract even though the Navy did not use the aircraft. As an example, the OV-1A (YAO-1A) was used primarily by the U.S. Army but was acquired under a Navy Contract.
- Some of the SACs on the CD-ROM are for experimental and pre-flight designs that never became production aircraft.
- Keep in mind that SACs were published to provide a representative reference at an appropriately classified level and not as operating information.
- Nothing was built from the SAC 3-view drawings, hence, they were only required to be generally representative of the aircraft configuration and should not be considered as authoritative for reproductions at any scale.
- In some cases SACs were updated as development and/or service use introduced equipment or configuration changes, but this was not consistently done. Therefore, the publication date of a SAC does not necessarily reflect the applicable date of the information contained on the SAC.
- All SACs on the CD-ROM have been reviewed for Declassification and have been Declassified.
