## Abstract

An aircraft in which it is possible to replace windshield panes of the mineral type with windshield panes of the organic type and vice versa, without the frame of the aircraft structure having to be modified. The pane is held in place on the frame by a window pane retainer specific to the pane. The frame has no through-holes opening to the outside of the aircraft for fastening the pane. The window pane retainer specific to a pane of the organic type has pins passing through the acrylic panes. The disclosed embodiments also relate to a method of replacing a pane of a first type with a pane of a second type.

## Claims

### Claim 1

A method for replacing an aircraft windshield pane of a first, mineral or organic, type, called a first type, which is held in place on a frame of a structure of said aircraft by means of a window pane retainer specific to said first type of pane, with a windshield pane of another, acrylic or glass, type, called a second type, comprising:
removing fastening elements and the window pane retainer holding the pane of the first type in place;
removing the pane of the first type,
and comprising the subsequent steps of:
placing the pane of the second type in a position of the pane of the first type;
replacing the window pane retainer for the pane of the first type with a window pane retainer specific to the second type; and
fastening the window pane retainer of the second type on the frame with fastening elements having the same shape and location as those of the window pane retainer of the first type,
one of the window pane retainers having pins passing through the pane of the organic type.

### Claim 2

An aircraft wherein at least one windshield pane of the organic type is held in place by a window pane retainer fastened to a frame of a structure of said aircraft, said at least one pane being interposed between a first face, called the bearing face, of the frame and a first face of the window pane retainer, and wherein:
the frame has no through-holes opening to the outside of the aircraft for fastening the pane,
the window pane retainer is fastened to the frame by fastening elements, inside the aircraft, passing through the through-holes in the frame,
the window pane retainer has pins distributed on the first face, each pin having an elongate shape and engaging in an orifice passing through the pane in a thickness of said pane.

### Claim 3 (depends on 2)

The aircraft according to claim 2, wherein each pin has a length between a minimum length necessary to hold the pane in the window pane retainer-frame assembly in the event of deformation of the pane and a maximum length such that a first end of each pin, the one closest to the bearing face of the frame, is not in contact with said bearing face of said frame.

### Claim 4 (depends on 2)

The aircraft according to claim 2, wherein the frame has, on the bearing face, a blind hole facing the orifice in the pane.

### Claim 5 (depends on 2)

The aircraft according to claim 2, wherein the pins and the window pane retainer are produced as one piece.

### Claim 6

A window pane retainer for holding a windshield pane of the organic type on a frame of an aircraft structure, wherein the window pane retainer has pins distributed on a first face, each pin having an elongate shape and being intended to engage in an orifice passing through the pane in a thickness of said pane.

### Claim 7 (depends on 6)

The window pane retainer according to claim 6, in which each pin is produced as one piece with the window pane retainer.
