N3918Y

This entry describes airframe N3918Y, a Gulfstream G450 built in 2008 by Gulfstream Aerospace Corporation with manufacturer's serial number 4112. The aircraft is registered in the US and is owned by the corporate entity JOHN R MILLER ENTERPRISES V LLC, based in Salt Lake City, UT, US; it is recorded on U.S. registry to that corporate owner. The airframe is a two‑engine, long‑range business jet maintained in an executive configuration and has the standard registry and operating history associated with owner‑operated or corporate flight departments. Notable registry actions include its ongoing registration under the named corporate owner and operation from its Salt Lake City base.

The airframe is commonly outfitted in a typical executive cabin layout—commercially configured between 12–16 executive seats although it is certified for 22 seats—with forward and aft galley and lavatory options available depending on owner outfitting. Avionics are provided by Gulfstream PlaneView II with Honeywell‑based systems including TCAS and Honeywell radio suites, supporting complex IFR international operations and typical corporate mission profiles. Based from Salt Lake City, UT, the jet’s 4,350 nm range and 459 kt cruise speed permit transcontinental and some intercontinental routings, frequently used for owner/operator business travel and corporate shuttle missions. Maintenance considerations align with twin‑engine Rolls‑Royce TAY‑powered Gulfstream practice, with scheduled heavy maintenance and engine programs driven by utilization and corporate ownership patterns.

The Gulfstream G450 occupies the long‑range heavy light/large cabin class for late‑2000s business jets, offering transcontinental capability with high cruise speed and a 45,000 ft ceiling. It competes with similarly classed aircraft from Bombardier and Dassault in owner/operator and charter markets, attracting buyers seeking range, cabin size flexibility, and mature avionics suites such as Gulfstream PlaneView II. Resale and maintenance considerations for a 2008 G450 center on engine program status (Rolls‑Royce TAY 611‑8C), completed maintenance events, and cabin refurbishments relative to certified 22‑seat capacity versus typical executive layouts.
