N474X

This entry covers airframe N474X, a Gulfstream G-IV SP built in 2001 with serial number 1445. The airframe is owned by WASHINGTON PENN PLASTIC CO INC, a corporate registrant based in Washington, PA, US, and is registered in the US. Retained on corporate registry and operated from the owner’s Pennsylvania base, this aircraft reflects a corporate-operated large‑cabin Gulfstream of its vintage; publicly available records list the unit by its tail number and builder serial without additional change-of-ownership events published.

The cabin of N474X is configured in a typical executive large‑cabin layout and is certificated for seating up to 22, though common operator layouts for this model range between 12–14 passengers for executive comfort. Operated by the corporate owner from Washington, Pennsylvania, the airframe’s mission profile is consistent with long‑range corporate transport, capable of transcontinental and transoceanic sectors within its 4,220 nm range at a cruise near 459 kts and operating to flight levels up to 45,000 ft. The twin Rolls‑Royce Tay (611 series) engines, each rated at 12,450 lbf, define the airplane’s propulsion and associated maintenance program requirements for this specific airframe. Cabin amenities and specific avionics fit for N474X are aligned with large‑cabin executive standards for the Gulfstream G‑IV SP, with certificated seating and common operator reconfiguration options informing interior refurbishment or charter use decisions.

As a Gulfstream G‑IV SP airframe delivered in 2001, N474X sits within the long‑range, large‑cabin business jet segment offering transcontinental capability at high cruise speed and altitude. The combination of a 4,220 nm range, 459 kts cruise, and a 45,000 ft ceiling positions this G‑IV SP for demanding corporate transport missions; its twin Rolls‑Royce Tay powerplants and certificated 22‑seat capacity factor into lifecycle maintenance and interior refurbishment considerations that commonly drive buyer and operator decisions in the used large‑cabin market.
