N25SM

The airframe bearing tail number N25SM is a 1991-built Cessna 550 Citation II with serial number 550-0682. The airframe is registered in the United States and is recorded as owned by TWHISKEY AVIATION LLC, an LLC based in Lawton, OK, US. Publicly available registry notes and specific valuation or condition reports for this individual aircraft are not published; there are no additional documented ownership transfers or notable registry actions in the supplied data. Its operator/home base is effectively the owner’s listed location in Lawton, Oklahoma, as inferred from the registration entry.

This specific Citation II is configured with an 8-place executive layout (type-standard for Citation II), supporting typical light business transport missions such as short- to medium-range executive shuttle, point-to-point corporate movement, and on-demand charter within a roughly 1,900 nm radius. Avionics fit and outfitting details for this airframe are not published in the provided data; therefore, no assertions about modernisation, FMS or weather/terrain systems are made. Based from the owner’s location in Lawton, OK, typical operations for this aircraft would likely serve regional business centers and cross-country hops consistent with the model’s 403-knot cruise and 43,000-foot ceiling. Maintenance considerations for this airframe follow the Citation II fleet commonality, with attention to JT15D-4 engine life limits and airframe program requirements as applicable to 1991 production examples.

The Cessna 550 Citation II occupies a light-cabin, light-twin business jet niche offering transcontinental capability for its era with cruise speeds around 403 kts and executive seating for 8. Competing types in the market generally include contemporaneous light jets from Learjet and British Aerospace; buyer and charter demand tends to favor examples with upgraded avionics and strong maintenance records. For this airframe (serial 550-0682), resale and operational value will hinge on documented maintenance, avionics status, engine cycles on Pratt & Whitney Canada JT15D-4 powerplants, and overall exterior/interior condition, none of which are published in the supplied data.
