N508MM

This airframe, N508MM, is a British Aerospace-built Avro 146-RJ100 constructed in 1994 with manufacturer serial number E3247. The airframe was produced by British Aerospace (Avro) and is recorded as being owned by the Colombian corporation SAM - Sociedad Aeronáutica de Medellín, based in Bogotá, Colombia. Notably, the aircraft is registered in the United States and appears on the U.S. registry as US, a registry action that separates legal registration from corporate domicile. The airframe’s configuration and serial history indicate a typical mid-life regional jet status for RJ-series types, with operator-based maintenance and valuation reflecting its high-density cabin fit and four‑engine layout.

The airframe is configured with high-density single-class layouts in the typical RJ100 family range (Y100–Y112), supporting up to 112 passenger seats and optimized for short- to medium-haul regional sectors. Operationally, the aircraft’s four Honeywell LF507-1F turbofans deliver the redundancy and climb performance suited to frequent, high-frequency turnarounds and steep approach fields. Based out of Bogotá under corporate ownership by SAM - Sociedad Aeronáutica de Medellín, typical mission profiles would include dense regional charters, high-capacity scheduled flights, and sub‑2,000 nm trunk sectors capitalizing on the 1,800 nm range and 404 kt cruise. Maintenance considerations specific to this airframe include age-related systems checks for a 1994 build and continued support for the LF507 engine type.

The British Aerospace Avro 146-RJ100 (Avro RJ100) occupies a niche for high-density, short-to-medium regional operations with four-engine reliability and a relatively compact field performance envelope. Competing models historically include other regional jets and turboprops that emphasize economy over four‑engine redundancy; the RJ100’s appeal is in passenger capacity and STOL-capable airport access. Buyer and charter demand tends to focus on operators needing dense seating and steep approach capability, while resale and maintenance considerations center on airframe age, engine support for the Honeywell LF507 series, and the specialized cabin conversions tied to the Y100–Y112 seating family.
