Abstract
When a breakage occurs to the connecting links which connect a gas turbine engine to aircraft structure, the engine drops onto a fail/safe mounting. The drop is minimal in magnitude and the invention provides a visual means for appreciating that the drop and therefore the breakage, has occurred. Relative movement between engine and airframe frees a pop up member and enables it to project beyond the engine envelope, for observation by inspection.
