The latest data compiled by New York-based aviation researcher JETNET confirmed the shrinking pool of aircraft available for sale. A total of 5,675 aircraft were available for sale in Q1 2018 across all sectors (including rotary craft), which is down 680 aircraft (10.7%) over the same period last year. The largest fall was seen in the business jet sector with a fall of some 350 units to just 9.3% of the active worldwide fleet. The survey also confirmed that business jets are taking an average of 16 days less to sell than last year.
