Aviation Advisor (LKF, Kenosha) has phased out the sole Citation Sovereign from its Part 135-certified fleet, ch-aviation research reveals.
The 18.5-year-old aircraft, N83SD (msn 680-0106), is configured for up to eight passengers. Operated by Aviation Advisor since 2012, it completed four flights between June 2024 and April 2025, including the final flight under the company's 'LKF' code on April 6, 2025, between Kenosha, where it was based, and Fort Lauderdale International. No longer listed as Part 135-certified, the jet has performed four test flights around Fort Lauderdale International and Fort Lauderdale Executive since May.
Aviation Advisor's Part 135 certificate had previously included a Citation Sovereign+, which was retired at the end of 2023. The operator's current charter fleet comprises a Learjet 45XR, two Challenger 300s (one newly added), a Citation Jet 1+, two Citation Jet 2s, two Citation Jet 3s, two Citation Jet 4s, a Citation XLS+, a Falcon 2000S, and a G280.
In addition to charter services, Aviation Advisor provides aircraft management, acquisitions, and maintenance.
