N915WS

This article describes a specific airframe, the N915WS, a Cessna 525C CitationJet CJ4 built in 2018 with serial number 525C0283. The aircraft is owned by POET INC, a corporation based in Sioux Falls, SD, US, and is registered in the US; the registration and ownership are the principal recorded administrative actions for this airframe. Its market valuation is listed at $8,500,000, reflecting typical condition and equipment for a late-model CJ4. No other notable registry events or operator changes have been published for this airframe.

The cabin of this airframe is fitted in a typical executive CJ4 configuration offering an 8–11 place layout: a forward divan, a four-place club arrangement, and aft seats with optional belted lavatory installations. Avionics are equipped in the common CJ4 fit with the Rockwell Collins Pro Line 21 suite, supporting common business-jet navigation, communications and flight-management tasks. Operated by POET INC out of Sioux Falls, SD, the airplane is suited to short- to medium-length corporate missions and positioning flights within a transcontinental U.S. range; typical mission profiles include executive transport and company logistics. As a corporate asset, maintenance considerations align with manufacturer schedules for the Williams FJ44-4A engines and Pro Line 21 avionics, with mid-life inspection cycles expected for a 2018-built airframe.

The Cessna 525C CitationJet CJ4 occupies the light-cabin, long-range end of the Citation family, offering higher cruise speed and range than earlier CJ variants. With a cruise near 451 kts and a range of 2,165 nm, the CJ4 competes with light-to-midsize jets aimed at corporate operators and charter brokers. Common competitors include newer light jets from Embraer and Pilatus in similar mission roles; buyer demand favors late-model, well-equipped installations such as the Pro Line 21 fit found on this airframe. Resale and maintenance considerations for N915WS reflect the CJ4’s established support network, type-specific inspection items, and the residual value indicated by the $8,500,000 valuation.
