N711EC

The airframe bearing tail number N711EC is a 1980-built Learjet 35A, serial number 35-311, completed by Gates Learjet Corporation. The aircraft is owned by SEMPER PARATUS TD I LLC, an LLC based in Allentown, PA, US, and is registered in the US registry. Notable registry actions include its continued U.S. registration under the current ownership; valuation and condition assessments list the airframe at approximately $900,000, reflecting its late-1970s/early-1980s vintage and typical market depreciation for the model.

The aircraft typically features a standard executive cabin arranged in a typical 8–10-place layout; the exact onboard configuration for N711EC is not published. Operationally the airframe is suited to executive transport and light charter missions within the continental United States, exploiting the model’s transcontinental range capability in the 2,196 nm class and a high cruise speed around 440 kts. Based from Allentown, PA, the operator profile under SEMPER PARATUS TD I LLC suggests use for point-to-point business travel, requiring routine ageing-aircraft maintenance programs commensurate with a 1980 airframe and twin Garrett TFE731-series turbofan engines. Cabin amenities and specific avionics fit for N711EC are not published, which affects precise mission planning and passenger comfort descriptions.

The Learjet 35A family occupies the high-speed light business jet niche, prized for fast cruise and a high service ceiling of 45,000 ft, while offering modest cabin capacity (typically 8–10 seats). Competing models in similar mission roles include other light-to-midsize business jets of the era; buyer and charter demand for vintage Learjet 35A airframes often hinges on avionics upgrades, engine life remaining, and maintenance history. At an indicated value of $900,000, resale considerations focus on ongoing maintenance expenditures, parts availability, and the cost of modernizing avionics to current regulatory and operator standards.
