N602AT

This article concerns airframe N602AT, a 1989-built Cessna 550 Citation II with serial number 550-0606. The aircraft is registered in the United States and is owned by the corporation WDC EQUIPMENT LLC, based in Webster, Texas, which appears as the on-record owner and operator for this airframe. The airframe’s civil registry reflects a late-1980s production Citation II maintained in an eight-place executive configuration; notable registry actions are limited to standard U.S. corporate ownership records. Condition and valuation details are not published in the supplied data.

The fitted cabin for N602AT is an eight-place executive layout configured for business transport, reflecting typical mid-size light-jet corporate interiors of the era. Operated from Webster, Texas by WDC EQUIPMENT LLC, the aircraft’s mission profile would customarily include short to medium-range point-to-point executive trips, leveraging its near-2,000 nm range and transcontinental cruise capability. Avionics fit specifics are not provided; maintenance considerations for this individual airframe follow Pratt & Whitney Canada JT15D-4 engine common practices and inspection intervals appropriate to a 1989 airframe in corporate service. Unique amenities specific to this airframe are not published.

The Cessna 550 Citation II occupies the light-cabin, twin-engine business jet niche, offering higher cruise speeds and range than early Citation variants while retaining relatively simple systems and economical operating costs. With a cruise of 403 kts and a service ceiling of 43,000 ft, the type competes with contemporaries such as the Learjet 31/35 series and the Hawker 700/400 light-to-midsize jets. Buyer and charter demand for late-1980s Citation IIs typically centers on cost-conscious operators seeking reliable, well-understood airframes; resale and maintenance considerations include JT15D-4 engine support, life-limited component tracking for a 1989 serial, and avionics upgrade potential to meet modern airspace and charter requirements.
