N70NB

The airframe bearing tail number N70NB is a 1981-built Cessna 501 Citation I/SP, serial 501-0209, manufactured by Cessna Aircraft Company (now Textron Aviation). The airframe is currently owned by the corporate entity M-5 TEXAS ENTERPRISES LLC, based in Weslaco, TX, US, and is registered in the US civil registry. The record for this individual aircraft reflects that it is registered to M-5 TEXAS ENTERPRISES LLC and operated in an executive configuration; valuation and detailed condition reports are not published.

This specific Citation I/SP is outfitted in an executive cabin layout typically accommodating six to eight passengers and is certified for single‑pilot operation, reflecting the I/SP designation. Typical missions for the airframe include short to mid-range business travel within continental North America, capitalizing on a cruise speed of 352 kts and a maximum ferry/mission range near 1,328 nm. The operator based in Weslaco, TX would commonly deploy the aircraft for executive transport and on-demand charter-like missions; avionics fit and recent refurbishments for this particular tail are not published. Maintenance considerations for this airframe align with standard Citation I/SP practices for two JT15D-1 engines, focusing on hot-section inspections and time-between-overhaul planning for Pratt & Whitney Canada turbofans.

The Cessna 501 Citation I/SP occupies the light business jet niche, offering a single‑pilot capable two-engine platform with transcontinental-short range performance and a practical executive cabin for small corporate groups. Competing models historically include other 1970s–1980s light jets from manufacturers such as Learjet and Dassault Falcon in shorter-range configurations. Buyer and charter demand for airframes like N70NB is influenced by airframe age, engine hours, and maintenance records; resale and operational costs typically reflect the need for diligent engine program participation and component support for legacy JT15D-powered Citations.
