- SC-717 was laid down 30 July 1942 by Fisher Boat Works at Detroit, launched 14 December 1942, entered Navy service on 14 May 1943, and is identified as a SC-497-class submarine chaser with a wooden hull, diesel propulsion, and a 28-person complement.

- Limitations
- NavSource is an archival photo/reference source rather than a DANFS entry; its page says no DANFS history is available for SC-717. The page labels the 14 May 1943 commissioning entry 'USS PC-717,' which conflicts with the Navy's SC designation and the batch's corrected hull identity; that label is not adopted as a separate PC vessel.

- PDF p. 10, lines/table entry for WAVR 434; pp. 9-10 background on Air Class WAVRs
- Finding type
- vessel_history
- Finding
- The Coast Guard table identifies WAVR-434 Air Lapwing as ex-SC-717, entering Coast Guard service on 30 October 1945 and being sold on 19 January 1948. The surrounding text identifies the WAVR conversions as 110-foot wooden Navy submarine chasers used for air-sea rescue and records that many were placed in commission in reserve because of crew shortages.

- Limitations
- The PDF is an archival compiled reference hosted by defense.gov, not a Navy or Coast Guard DANFS history. It documents transfer and disposal dates but does not characterize asbestos, exposure, or the later private-vessel history of this hull.

[4]U.S. Coast Guard, Air Class Cutters (13 April 2020) [museum_official]
- Locator
- Air Class Cutters page, overview and list of Air Class cutters
- Finding type
- historical_record
- Finding
- The Coast Guard describes the Air Class as Navy SC 497-class patrol boats transferred for air-sea-rescue duties and states that few became operational because of postwar personnel shortages; Air Lapwing appears in the official list of Air Class cutters.

- Air Class cutters and Coast Guard personnel, post-World War II
- Limitations
- Class-level Coast Guard history, not a material survey of SC-717. The page's generic dimensions, builder, propulsion, and complement are not used as ship-specific values because the Air Class comprised transferred boats from different builders and records.

[5]Authenticated CourtListener exact-name and hull-number sweep: four required base queries [other_primary]
- Locator
- search_ledger sl-uss-sc-717-sc717-01 through -04
- Finding type
- litigation_documented
- Finding
- No qualifying asbestos litigation naming USS SC-717, SC-717, or the identified Air Lapwing hull was returned in the four required authenticated base searches: exact-name opinion, exact-name docket, hull-number opinion, and hull-number docket.

- Study period
- 2026-10-03
- Limitations
- A no-result search does not prove that no unindexed pleading, docket attachment, or non-public record exists. No asbestos-qualified variant was run because none of the four base queries overflowed its 20-result page. This is a litigation-search result, not a finding that asbestos was absent from the vessel.

[6]Batch source review and public-source sweep for SC-717 asbestos documentation [other_primary]
- Locator
- search_ledger sl-uss-sc-717-sc717-05 and source review notes in BATCH-8091-REPORT.md
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, shipyard work package, or primary-source material list naming SC-717 was located. Asbestos documentation for this hull is therefore unknown.

- Limitations
- The absence of a located public record does not establish absence of asbestos aboard. Construction era, wooden hull, or diesel propulsion cannot be used to infer ship-specific asbestos products, quantities, exposure, or present condition.
