A duct installation, for example a rear casing 4 and an exhaust duct 8, eg jet pipe, of a gas turbine engine, comprises a first tubular member, eg the rear casing 14, having a main body 12 and an end section 14 which are separable at a releasable coupling eg including end flanges 18, 20 and clamping member 16. The end section 14 engages, eg telescopically, a second tubular member, eg the exhaust duct 8, so that the end section 14 may be axially displaced with respect to the second tubular member 8 when the coupling 16, 18, 20 is released, eg to provide access to the engine or to permit removal of the engine without disturbing the exhaust duct 8. A seal 34 may be provided between the end section 14 and the exhaust duct 8. The end section 14 may take with it a liner section 36. |
