The preowned business jet market tightened throughout the first half of the year and by June had dipped to the lowest percentage of aircraft for sale, 9.1 percent, since the beginning of the “Great Recession,” according to JetNet’s most recent market update covering the first half of the year.

In June, 1,966 preowned business jets were for sale globally, compared with 2,301 a year earlier. This marked a 1.7 percentage drop in the number of preowned aircraft available for sale, which was at 10.8 percent by the midpoint of 2017.

Available preowned turboprops are even more scarce, with 6.6 percent of the in-service fleet available for sale in June. This compares with 7.6 percent a year earlier. Helicopters showed similar trends: 5.8 percent of in-service turbine helicopters were available in June, compared with 6.7 percent a year earlier; and 5.4 percent of piston helicopters were on the market in June versus 5.6 percent a year earlier.

During the first six months, 1,344 business jets exchanged hands, a 0.2 percent increase from the same period in 2017. Average days on market dropped by 26 to 297 for business jets. Turboprop sales, however, took 13 days longer on average, at 307. In all, 651 business turboprops were sold in the first half of the year, relatively flat with the year before.
