An engine mounting arrangement is provided for supporting a gas turbine engine. The mounting arrangement comprises a module adaptor mounted to an overhead or a ground based carrier for rotation about a substantially horizontal axis. The module adaptor extends horizontally from a base to an axially-opposed distal end having a first mounting interface configured for attachment to a module of the engine. The module adaptor holds the engine by the module to which it is attached and with the other engine modules projecting in a cantilever fashion from the supported module.

1. An engine mounting apparatus suited for supporting a turbofan engine; the mounting apparatus comprising: a module adaptor rotatably mounted to a carrier for rotation about a substantially horizontal axis, the carrier being supported from an overhead support structure, the module adaptor having an open framework extending horizontally from a base mounted to the carrier to an axially-opposed distal end, the distal end having a first mounting interface configured for attachment to the engine, the module adaptor being rotatable relative to the carrier while holding the engine on the open framework. 2. The engine mounting apparatus defined in claim 1, wherein the turbofan engine has a fan case, and wherein the module adaptor is configured for projecting into the fan case, the first mounting interface being mountable to a fan drive of the engine. 3. The engine mounting apparatus defined in claim 1, wherein the open framework comprises a hollow cone-shaped support including an array of circumferentially spaced-apart structural members extending between the base and the axially opposed distal end. 4. The engine mounting apparatus defined in claim 3, wherein adjacent brace members extend between adjacent structural members and are axially offset about the hollow cone-shaped support to provide for a discontinuous load path in a circumferential direction. 5. The engine mounting apparatus defined in claim 1, wherein the module adaptor further comprises a fan case mounting ring detachably fixed to a front side of the carrier, the fan case mounting ring having a second mounting interface for attachment to a fan case of the gas turbine engine, and wherein the distal end of the open framework is configured to project into the fan case for connection to the fan drive of the engine, the fan case mounting ring and the open framework providing a dual load path between the module adaptor and the engine. 6. The engine mounting apparatus defined in claim 5, wherein the fan case mounting ring and the open framework are independently connectable to the engine. 7. The engine mounting apparatus defined in claim 5, wherein the carrier has a cylindrical passage extending therethrough, the fan case mounting ring being mounted about the cylindrical passage, and wherein the open framework has a cone-shaped body adapted to be mounted into the cylindrical passage from a rear side of the carrier opposite to the front side thereof, the cone-shaped body projecting axially forwardly from said cylindrical passage and the fan case mounting ring. 8. The engine mounting apparatus defined in claim 6, wherein the fan case mounting ring has a series of circumferentially spaced-apart tabs projecting radially outwardly from a periphery thereof for axial engagement behind a corresponding series of lugs provided on the front side of the carrier, the tabs axially retaining the fan case mounting ring on the carrier. 9. The engine mounting apparatus defined in claim 1, wherein the module adaptor has a second mounting interface which is axially spaced-apart from the first mounting interface and on a larger diameter than that of the first mounting interface, the second mounting interface being adapted to be detachably fixed to an outer structure of the engine. 10. The engine mounting apparatus defined in claim 9, wherein the module adaptor further comprises a mounting ring separate from the open framework, the first and second mounting interfaces being respectively provided on the mounting ring and on the open framework. 11. The engine mounting apparatus defined in claim 10, wherein the open framework is detachably mounted to the mounting ring which is in turn detachably mounted to the carrier. 12. An engine mounting apparatus suited for a turbofan engine, the engine mounting apparatus comprising: a module adaptor projecting horizontally from a carrier, the module adaptor being shaped to fit within an inlet end of a fan case of the turbofan engine, the module adaptor having a first mounting interface for connection to a fan drive within the fan case, the module adaptor configured for cantileveringly supporting the turbofan engine from the fan drive, the module adaptor further comprising a second mounting interface disposed axially rearwardly from the first mounting interface and on a larger diameter than that of the first mounting interface for connection to the fan case of the turbofan engine, wherein the module adaptor comprises a fan case mounting ring and an internal support projecting from the carrier, the fan case mounting ring being connected to the fan case, whereas the internal support is connected to the fan drive, and wherein the fan case mounting ring and the internal support are independently connectable to the engine. 13. The engine mounting apparatus defined in claim 12, wherein the first mounting interface comprises a conical support having an annular base detachably mounted to the carrier and a distal end configured for mating engagement with the fan drive of the turbofan engine. 14. An engine mounting apparatus suited for supporting a turbofan engine; the mounting apparatus comprising: a module adaptor mounted to a carrier for rotation about a substantially horizontal axis, the module adaptor comprising an internal support configured to extend into a fan case for connection to a fan drive of the engine, the internal support extending horizontally from a base mounted to the carrier to an axially-opposed distal end, the distal end having a first mounting interface configured for attachment to the fan drive of the engine for rotatably supporting the engine in a cantilevered fashion from said internal support, wherein the module adaptor further comprises a fan case mounting ring detachably fixed to a front side of the carrier, the fan case mounting ring having a second mounting interface for attachment to the fan case of the gas turbine engine, the fan case mounting ring and the internal support providing a dual load path between the module adaptor and the engine.
