The US Coast Guard received 23 ex UASF HC-131As from the USAF in 1976 as a stop gap replacement for the HU-16 pending delivery of the HU-25 Guardian. A few of these were held in storage at MASDC for spares use. 5805 (ex 52-5805) was later registered to Central Air Service as N81559 in May 1989 and sold to Starship Inc in 1996. The registration was cancelled in July 1997 as exported to Mexico but the aircraft remained in store at Avra Valley and was later scrapped. The nose survives in the Pima museum collection.
