N440RD

The airframe bearing tail number N440RD is a Hawker Siddeley HS-125-400F, serial 25270, manufactured by Hawker Siddeley. This specific airframe is recorded as owned by Rubloff Aviation and is registered in the US; detailed historical ownership transfers and operator basing are not published beyond that registration. There are no publicized recent major registry actions or a published valuation for this individual aircraft; condition highlights and maintenance status are likewise not published. The airframe’s lineage within the HS-125 family and its retained Garrett/Honeywell TFE731 series turbofans position it as a late-variant executive/mid-size business jet example within corporate registries.

The HS-125-400F airframe such as N440RD typically supports a corporate executive interior in single-aisle, forward cabin configurations accommodating business missions; specific seating and exact cabin layout for this registration are not published. Avionics fits for the -400F subvariant often include contemporary upgrades compatible with the TFE731 powerplant family, though the exact panel and certification stamps for N440RD are not published. Operationally, an HS-125-400F with a 2,420 nm range and 430 kts cruise is used on regional to transcontinental business routes, point-to-point charter work, and corporate transport; maintenance considerations focus on TFE731 hot-section inspections and aging-airframe corrosion control programs tailored to each operator’s base and utilization rate.

The Hawker Siddeley HS-125-400F occupies the mid-size business jet niche, offering a balance of transcontinental range and high cruise speed for its era. Competitors in secondary markets include later-model light-to-midsize business jets that emphasize newer avionics and improved fuel efficiency; consequently, buyer and charter demand for specific airframes like N440RD depends heavily on completion condition, avionics refresh, and engine time remaining. Resale and maintenance considerations emphasize TFE731 overhauls, parts availability from Garrett/Honeywell support channels, and the aircraft’s serial-specific maintenance records.
