N155ER 1984 Learjet 55ER

Overview

This entry concerns the individual airframe bearing U.S. registration N155ER, a Gates Learjet 55ER built in 1984 with serial number 55-098. The aircraft was manufactured by Gates Learjet Corp and is recorded in corporate ownership by Air Medical Services LLC, a corporation based in Coral Gables, FL, US. The current documented ownership reflects operation in an air medical and corporate support environment, and registry records identify the aircraft as U.S.-registered.

Operations & Cabin

The specific airframe N155ER accommodates up to 13 seats, consistent with high-density executive or medical transport interiors used by corporate and air ambulance operators. Typical mission profiles for this particular aircraft combine medium- to long-range point-to-point flights up to 2,244 nm and high-speed cruise operation near 419 kts, often conducted from a Florida base given the documented owner location. Avionics fit and interior specifics for this serial are not listed here, but operational use by Air Medical Services LLC suggests configurations and maintenance regimes oriented toward mission readiness, rapid turnaround, and specialized cabin equipment where fitted. Maintenance considerations for a mid-1980s Learjet commonly center on engine overhauls, avionics upgrades and corrosion control given the aircraft’s age.

Model & Market Context

The Gates Learjet 55ER family represents a mid-size, high-performance business/multi-mission turbofan jet from the 1980s, offering transcontinental capability in its class. With a maximum service ceiling of 51,000 ft and twin Honeywell TFE731 powerplants rated at 3,700 lbf each, the model competes historically with contemporaries for corporate and air ambulance roles.
