On 4 September 2022, a chartered Cessna 551 business jet registered in Austria was scheduled to fly from Jerez, Spain, to Cologne, Germany. Early in the flight, after takeoff, the aircraft's pilot notified air traffic control about a cabin pressure malfunction. After the aircraft passed the Iberian Peninsula, no further contact could be established.

The Cessna Citation II models are light corporate jets built by Cessna as part of the Citation family. Stretched from the Citation I, the Model 550 was announced in September 1976, first flew on January 31, 1977, and was certified in March 1978. The II/SP is a single pilot version, the improved S/II first flew on February 14, 1984 and the Citation Bravo, a stretched S/II with new avionics and more powerful P&WC PW530A turbofans, first flew on April 25, 1995. The United States Navy adopted a version of the S/II as the T-47A. Production ceased in 2006 after 1,184 of all variants were delivered.
