a bypass duct configured to direct air through a flow path to provide thrust to propel the gas turbine engine, the bypass duct including an outer wall that defines an outer boundary of the flow path and an inner wall that defines an inner boundary of the flow path,

an inlet cowl located in the bypass duct and configured to collect a portion of the air flowing in the bypass duct, the inlet cowl extending between a forward end thereof and an aft end thereof, the inlet cowl formed to define an inlet at the forward end and an outlet at the aft end, and

a heat-exchanger assembly removably coupled with the inlet cowl and configured to receive the portion of the air from the outlet of the inlet cowl and to transfer heat from the heat-exchanger assembly to the portion of the air to cool a fluid within the heat-exchanger assembly, the heat-exchanger assembly including a heat exchanger and an inlet shroud coupled with the heat exchanger and engaged with the inlet cowl to direct the portion of the air through the heat exchanger, and the inlet shroud includes a shroud housing arranged around the heat exchanger and a compliant joint coupled with the shroud housing and engaged with the inlet cowl along the outlet of the inlet cowl to provide a seal between the inlet cowl and the heat-exchanger assembly,

wherein the compliant joint has a continuous band and a plurality of deflectable tabs that are formed by a plurality of slots that extend into the compliant joint toward the continuous band, the plurality of deflectable tabs are configured to elastically deform in response to sliding the compliant joint onto and off of the inlet cowl to allow the heat-exchanger assembly to be separated from the inlet cowl and removed from the bypass duct.
