N351GC

The South Carolina King Air that became N375BC

Beech B300 serial FL-56 was South Carolina's N351GC through the 2025 season, then moved to Yellowstone Leasing in the January 2026 FAA transfer packet.

N375BC is the current registration for Beech B300 serial FL-56, the same airframe JetSweep previously tracked as South Carolina's N351GC. Under the old mark, the aircraft carried Mode-S A3E91D and showed a Columbia/KCUB-centered pattern that belongs in South Carolina's historical aircraft record.

The FAA registration-history packet explains the break. The bill of sale is dated Jan. 6, 2026 and transfers FL-56 from the University of South Carolina to Yellowstone Leasing LLC for $2,163,010.48. Yellowstone's registration application was signed Jan. 9, 2026, and the FAA issued the N375BC certificate on Mar. 4, 2026 with Mode-S A4467A.

The travel after the transfer window does not look like hidden continuation of the South Carolina fleet. Before Jan. 9, JetSweep has 20 South Carolina-scoped N351GC trips in this served slice, including the Nov. 1, 2025 KCUB -> KTUP -> KCUB round trip that lines up with South Carolina at Ole Miss game weekend support. After Jan. 9, the old hex has four rows that shift through Anderson, Pensacola, Key West, and Smyrna, and the current A4467A activity through Jun. 19, 2026 is KAND/KMQY/KPNS/KNEW-centered rather than KCUB-centered.

The clean public read is therefore time-bound. FL-56 is a South Carolina-owned aircraft for trips before the January 2026 transfer window. After that, it should display as Yellowstone Leasing LLC / post-sale airframe history unless a separate document ties a specific trip back to South Carolina.
