Zusammenfassung:	A blade outer airseal (BOAS) assembly of a gas turbine engine (20) includes a plurality of BOAS segments (70) arrayed circumferentially about the engine central longitudinal axis (A), and a plurality of BOAS carriers (72) located radially outboard of the plurality of BOAS segments (70). Each BOAS carrier (72) is supportive of at least one BOAS segment (70). The BOAS assembly includes plurality of adjustment levers (76). Each adjustment lever (76) is operably connected to at least two BOAS carriers (72) of the plurality of BOAS carriers (72). Rotation of each adjustment lever (76) about a respective pivot axis (84) urges movement of the plurality of BOAS segments (70) in a radial direction thereby adjusting a radial gap (68) between the turbine rotor (60) and the plurality of BOAS segments (70).
