Aircraft engine assembly stand

An assembly, comprising:

• an aircraft engine;
• and
• a stand, the aircraft engine mounted to the stand, the stand having:
• a support;
• a mount rotatably mounted to the support, the mount extending around a central axis and surrounding an engine-receiving space, the mount defining a lateral opening communicating with the engine-receiving space along a direction transverse to the central axis, the lateral opening sized for receiving the aircraft engine, the mount rotatable relative to the support about the central axis and about a transversal axis normal to the central axis, the mount being mounted to other support via a coupler having a coupler base secured to the support, and a coupler end being rotatable relative to the coupler base about the transversal axis, the mount mounted to the coupler end;
• and
• an adaptor, the aircraft engine secured to the mount via the adaptor, a gap defined between the aircraft engine and the mount, the adaptor extending across the gap, a portion of the gap being free of the adaptor,
• wherein the coupler includes a transmission having an input drivingly engageable by a tool and an output engaged to the mount for rotating the mount relative to the coupler end about the central axis.
