RESEARCH NOTES

About N100GG

Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.

Overview

This entry describes airframe N100GG, a 1977-built Cessna 501 Citation SP (operated in a Citation ISP / Stallion conversion configuration), manufacturer serial 501-0020. The airframe is registered in the US and is owned by 1MK Leasing LLC (Lindale, TX, US). The aircraft is configured and maintained as an executive transport with a seven-passenger layout and systems aimed at continued business/operator use.

Operations & Cabin

The cabin of N100GG is fitted in an executive seven-passenger configuration with a forward belted lavatory and an aft divan/three-place seating according to reports, supporting private business missions and short to mid-range point-to-point travel. Avionics fit reported includes a three-tube Garmin G950 suite, GTX-335/345 transponders, TCAS-1, TAWS-B, and WAAS/LPV capability, enabling modern navigation and traffic awareness for commercial or corporate operation. Typical missions for this airframe are transcontinental and regional business trips within its 1,600 nm range at cruise speeds near 385 kts and flight levels up to 41,000 ft; maintenance considerations include managing aged JT15D turbofan legacy components or documenting a Stallion conversion if the Williams FJ44 family powerplants have been installed per conversion listings.

Model & Market Context

The Cessna 501 Citation SP platform occupies the light business jet niche for eight-seat cabin operators seeking efficient short-to-medium range performance with modest acquisition costs for older airframes. Competing models in the same segment include light-cabin jets with similar speed and range profiles; demand is often driven by cost-conscious buyers or leasing entities for charter use. Resale and maintenance considerations for N100GG specifically hinge on engine configuration discrepancies between registry and conversion listings, the extent of avionics modernization, and the airframe’s documented modifications, all of which materially affect marketability and operating economics.
