DETAILED DESCRIPTION
Figs. 1 A and B illustrate a port and starboard side view, respectively, of a known helicopter illustrating various openings therein. A helicopter locking system comprises multiple locking components configured to secure various openings of the helicopter, such as crew door, cargo door, cargo door window, ebay, engine compartment, fuel tank, popup handle, and port window.
3o Figs. 2A to 43 illustrate embodiments of lock components for the various openings of the helicopter that are to be secured. Each of these lock components may be easily installed in the helicopter. Many of the lock components may be secured in a closed position by various known locking mechanisms, such as a standard pad lock, etc. A

Figs. 2A to 6 illustrate a crew door lock component 10 for securing a crew door to prevent opening thereof. Fig. 6 illustrates the crew door lock component 10 secured onto the crew door of the helicopter. The crew door has three handles (as seen on the left side of Fig. 6); namely, a top, a middle and a bottom handle.
As seen in Figs. 2A to 2D, the crew door lock component 10 comprises a bar piece 26 to with two linear segments 12, 14 joined at an angle to each other. This angle is sufficient to account for any curve or angle in the door between the plane of the crew door between the top handle and the middle handle and the plane of the crew door between the middle handle and the bottom handle.
The bar piece 26 also comprises three cross pieces 16, 18, 20 positioned at each of the ends of the segments 12, 14 and at the intersection point. Each of these cross pieces 16, 18, 20 corresponds with one of the handles of the crew door.
The shape of each of the cross pieces 16, 18, 20 may depend upon the shape of the handle to which it corresponds. For example, in the configuration shown in Figs. 2A
to 2D it is assumed that the top handle has a cylindrical shape while the middle and bottom handles have a rectangular popup shape. In the configuration shown in Figs. 2 A to 4C a top cross piece 20 has a cylindrical shape corresponding in size to the top cylindrical handle such that the top cross piece 20 may be slid over the top handle for engagement therewith. In the same configuration both a middle cross piece 18 and a bottom cross piece 20 have a rectangular shape corresponding in size to the middle and bottom handles, respectively, such that the middle cross piece 18 and the bottom cross piece 20 may be slid over the middle and bottom handles, respectively.
The crew door lock component 10 further comprises a locking part 22 that is engageable with the bottom cross piece 16 to secure the crew door lock component 10 in place. The locking part 22 may be inserted into the bottom cross piece 16 (as shown in Figs. 5A and B). When the locking part 22 is inserted into the bottom cross piece 16, the bottom handle of the crew door is prevented from lifting, thus opening of the crew door is also prevented.
Both the locking part 22 and the bottom cross piece 16 have some mechanism to lockingly secure these two parts together. Figs. 5A and B show both the locking part 22 and the bottom cross piece 16 have holes 24B and 24A that are aligned when the locking part 22 is completely inserted in the bottom cross piece 16. A known locking mechanism may then be inserted through the aligned holes 24A,B to secure the locking part to the bottom cross piece 16.
Figs. 7A to 11 C illustrate a cargo door lock component 100 for securing a cargo door to prevent opening thereof. Fig. 8 illustrates the cargo door lock component secured to the cargo door of the helicopter. The cargo door is a forward aft sliding door on the helicopter. The cargo door slides right to left or left to right.

These two holes are configured to receive the pin part 104 therein to secure the hook part 102.
3o Figs. 12A to 15C illustrate a cargo door window lock component 200 for securing a cargo door window of a helicopter to prevent opening thereof. Figs. 13A and B
illustrate the cargo door window lock component 200 secured onto the cargo door window of the helicopter. The cargo door window has an emergency handle slot used to guide an emergency release lever. The emergency release lever may have a hole therein, which may be used for engagement of the emergency release lever and the cargo door window lock component 200.
As seen in Figs. 12A to C, 14 and 15A to 15C, the cargo door window lock component 200 has a cross piece 202 that is configured to be inserted in to the emergency handle slot. Extending from the cross 202 is a bar piece 204 extending orthogonally therefrom. The bar piece 204 may have a perpendicular section 206 of sufficient size to extend over the width of the emergency release lever and a vertical section 208. The vertical section 208 has a far end 210 at which is located a hole that can be aligned with the hole in the emergency release lever. The vertical section 208 is configured such that the hole at the far end 210 can be aligned with the hole in the emergency release lever.
A known locking mechanism may then be inserted through the aligned holes of the cargo door window lock component 200 and the emergency release lever to secure the cargo door window lock component 200 in the emergency handle slot, thus prevent the emergency release lever from sliding to open the cargo door window.
Figs. 16A to 21 C illustrate an ebay lock component 300 for securing an ebay of a 2o helicopter to prevent opening thereof. Figs. 22A and B illustrate the ebay lock component 300 secured onto the ebay door of the helicopter. The ebay door is contoured where the door meets the helicopter frame. There is a frame inside the ebay door on the helicopter structure.
As seen in Figs. 16A to 19, the ebay lock component 300 comprises a first part and a second part 304 that are engageable with each other. The first part is positioned along the outside of the ebay door. The first part 302 has a generally v-shaped portion 306 that is configured according to the shape of the ebay door. The first part also has an extended piece 308 that extends at an angle from the v-shaped portion 306 in proximity to a slot 310 in the v-shaped portion 306. A hole is positioned at the end of the extended piece 308. The first part 302 follows the contours of the frame of the helicopter at the point where the ebay door and the frame meet.
Figs. 2A to 6 illustrate a crew door lock component 10 for securing a crew door to prevent opening thereof. Fig. 6 illustrates the crew door lock component 10 secured onto the crew door of the helicopter. The crew door has three handles (as seen on the left side of Fig. 6); namely, a top, a middle and a bottom handle.
As seen in Figs. 2A to 2D, the crew door lock component 10 comprises a bar piece 26 to with two linear segments 12, 14 joined at an angle to each other. This angle is sufficient to account for any curve or angle in the door between the plane of the crew door between the top handle and the middle handle and the plane of the crew door between the middle handle and the bottom handle.
The bar piece 26 also comprises three cross pieces 16, 18, 20 positioned at each of the ends of the segments 12, 14 and at the intersection point. Each of these cross pieces 16, 18, 20 corresponds with one of the handles of the crew door.
The shape of each of the cross pieces 16, 18, 20 may depend upon the shape of the handle to which it corresponds. For example, in the configuration shown in Figs. 2A
to 2D it is assumed that the top handle has a cylindrical shape while the middle and bottom handles have a rectangular popup shape. In the configuration shown in Figs. 2 A to 4C a top cross piece 20 has a cylindrical shape corresponding in size to the top cylindrical handle such that the top cross piece 20 may be slid over the top handle for engagement therewith. In the same configuration both a middle cross piece 18 and a bottom cross piece 20 have a rectangular shape corresponding in size to the middle and bottom handles, respectively, such that the middle cross piece 18 and the bottom cross piece 20 may be slid over the middle and bottom handles, respectively.
The crew door lock component 10 further comprises a locking part 22 that is engageable with the bottom cross piece 16 to secure the crew door lock component 10 in place. The locking part 22 may be inserted into the bottom cross piece 16 (as shown in Figs. 5A and B). When the locking part 22 is inserted into the bottom cross piece 16, the bottom handle of the crew door is prevented from lifting, thus opening of the crew door is also prevented.
Both the locking part 22 and the bottom cross piece 16 have some mechanism to lockingly secure these two parts together. Figs. 5A and B show both the locking part 22 and the bottom cross piece 16 have holes 24B and 24A that are aligned when the locking part 22 is completely inserted in the bottom cross piece 16. A known locking mechanism may then be inserted through the aligned holes 24A,B to secure the locking part to the bottom cross piece 16.
Figs. 7A to 11 C illustrate a cargo door lock component 100 for securing a cargo door to prevent opening thereof. Fig. 8 illustrates the cargo door lock component secured to the cargo door of the helicopter. The cargo door is a forward aft sliding door on the helicopter. The cargo door slides right to left or left to right.
A handle for the cargo door is lifted resulting in a latch disengaging after which the door may slide along rollers at a top edge of the door opening.
As seen in Figs. 7A to C and 9, the cargo door lock component 100 comprises a hook part 102 and a pin part 104. The hook part 102 has a first end 110 with a generally 2o hook shape for engagement with a frame part 108 of the cargo door. A second end 112 of the hook part is shaped to receive the pin part 104 therein.
