Abstract: A gearbox mounting link between a gas turbine engine structure and a gearbox mounting location comprises an engine attachment piece rotatably secured to the gas turbine engine structure. The engine attachment piece comprises first and second plates extending in parallel planes and separated by a gap having a gap width. A gearbox attachment piece is situated between the parallel plates, and is secured to the gearbox. A breakable primary retention fastener extends snugly through the parallel plates and the gearbox attachment piece, thereby rigidly retaining the gearbox with respect to the gas turbine engine in two degrees of freedom so long as the breakable primary retention fastener remains intact. A durable secondary retention fastener extending snugly through the parallel plates, and extends with clearance through the gearbox attachment piece via an oversized fastener passage, thereby constraining the gearbox attachment piece in the event that the breakable primary retention fastener breaks.

Abstract: An assembly for a coupling together rotatable components according to an example of the present disclosure includes, among other things, a rotor shaft extending along a centerline axis, the rotor shaft defining an inner bore extending from an axial end of the rotor shaft, a gear mounted on an outer diameter of the rotor shaft, a lock nut threadedly engaged with the outer diameter of the rotor shaft such that the lock nut abuts against an axial end face of the gear, and a retainer including a step portion extending from a head portion and including a projection portion extending from the step portion. The projection portion is insertable into the inner bore to bias the lock nut against the axial end face of the gear, and the step portion is dimensioned to establish an interference fit with the rotor shaft along the inner bore. A starter assembly and a method of assembly are also disclosed.

Abstract: An oil reservoir assembly includes a tank, a return passage, a pressurization valve, a first passage, and a vent valve. The tank includes a canister, a fill port, an first oil outlet, an second air outlet, and an inlet. The inlet is disposed in the canister and is connected to a restrictor. The return passage is connected to the inlet of the tank and to a scavenge pump. The pressurization valve is fluidly connected to the second air outlet of the tank. The first passage is connected to the pressurization valve and to an accessory gearbox of the engine. The vent valve is disposed in the return passage and includes a body, a channel extending through the body, an inlet orifice, and an outlet orifice. The inlet orifice is disposed in an end of the body. The outlet orifice is fluidly connected to the inlet orifice via the channel.
