A routing plate for hydraulic lines, the routing plate comprising:
a forward side affixable to an aft gearbox surface;
an aft side to which first and second hydraulic components are affixable; and
a body extending between the forward and aft sides, the body being formed to define:
a first interfacial pathway by which the gearbox and the first hydraulic component are communicative,
a second interfacial pathway by which the gearbox and the first hydraulic component are communicative, and
third interfacial pathways by which the first and second hydraulic components are communicative via the body.

### Claim 2 (depends on 1)

The routing plate according to claim 1, wherein the forward and aft sides are parallel.

### Claim 3 (depends on 1)

The routing plate according to claim 1, wherein the body comprises:
a first portion corresponding in location to a portion of the aft side to which the first hydraulic component is affixable;
a second portion corresponding in location to a portion of the aft side to which the second hydraulic component is affixable; and
a third portion interposed between the first and second portions.

### Claim 4 (depends on 3)

The routing plate according to claim 3, wherein the first portion has a partially rectangular shape, the second portion has a partially rounded shape and the third portion is tapered from the first to the second portion.

### Claim 5 (depends on 3)

The routing plate according to claim 3, wherein the first interfacial pathways comprises a lube oil supply pathway running from the gearbox, through the first portion of the routing plate and into the first hydraulic component.

### Claim 6 (depends on 1)

The routing plate according to claim 1, wherein the second interfacial pathways comprises a pump drive interface running from the gearbox, through the first portion of the routing plate and into the first hydraulic component.

### Claim 7 (depends on 1)

The routing plate according to claim 1, wherein the third interfacial pathways comprise hydraulic pathways running from the second hydraulic component, through the second, third and first portions of the routing plate and into the first hydraulic component.

### Claim 8 (depends on 1)

The routing plate according to claim 1, wherein:
the first interfacial pathway comprises a lube oil supply pathway running from the gearbox, through the first portion of the routing plate and into the first hydraulic component,
the second interfacial pathway comprises a pump drive interface running from the gearbox, through the first portion of the routing plate and into the first hydraulic component, and
the third interfacial pathways comprise hydraulic pathways running from the second hydraulic component, through the second, third and first portions of the routing plate and into the first hydraulic component.

### Claim 9 (depends on 1)

The routing plate according to claim 1, further comprising a transfer tube disposed along one of the third interfacial pathways, the transfer tube comprising:
a first portion sealably disposable in the routing plate; and
a second portion sealably disposable in the first or second hydraulic component.

### Claim 10

A routing plate for hydraulic lines, the routing plate comprising:
a forward side affixable to an aft gearbox surface of a gearbox;
an aft side to which first and second hydraulic components are affixable; and
a body extending between the forward and aft sides, the body being formed to define:

a second interfacial pathway by which the gearbox and the first hydraulic component are communicative, and
third interfacial pathways by which the first and second hydraulic components are communicative via the body,
wherein the routing plate further comprises:
a rotatable propeller shaft;
an oil transfer tube, which is extendible from the gearbox and into the second hydraulic component; and
a gas turbine engine configured to generate rotational energy transmittable to the rotatable propeller shaft by the gearbox to drive rotations of the rotatable propeller shaft.

### Claim 11

A routing plate for hydraulic lines, the routing plate comprising:
a forward side affixable to an aft gearbox surface;
an aft side to which first and second hydraulic components are affixable;
a body extending between the forward and aft sides, the body being formed to define:
