An apparatus and method according to one or more embodiments are provided for a latching mechanism. The latching mechanism may be implemented, for example, as a positive lock latching mechanism that provides a positive indication when a latch is not engaged. In one example, an apparatus includes a latch arm comprising a slotted hole and a latch hook configured to engage a pin. The latch includes a bifold handle coupled to the latch arm, the bifold handle comprising a first handle portion and a handle extension portion, wherein the first handle portion comprises a lock hook configured to translate through the slotted hole to engage the pin and the handle extension portion is configured to move away from the first handle portion when the lock hook is not engaged with the pin. Additional systems and methods are also provided.

1. An apparatus comprising: a latch comprising:a latch arm comprising a first slotted hole and a latch hook configured to engage a pin; anda bifold handle coupled to the latch arm, the bifold handle comprising a first handle portion and a handle extension portion, wherein the first handle portion comprises a first end coupled to the latch arm and having a lock hook configured to translate through the first slotted hole to engage the pin and a second end coupled to the handle extension portion, wherein the handle extension portion is configured to move adjacent to the first handle portion when the lock hook is engaged with the pin, and the handle extension portion is configured to move away from the first handle portion when the lock hook is not engaged with the pin. 2. The apparatus of claim 1, wherein the first handle portion comprises: a first spring mechanism configured to limit the travel of the lock hook;a second spring mechanism configured to apply a force to the handle extension portion to move the handle extension portion relative to the first handle portion when the lock hook is not engaged with the pin; anda third spring mechanism configured to apply a force to the first handle portion to move the first handle portion relative to the pin when the lock hook is not engaged with the pin. 3. The apparatus of claim 2, wherein the first spring mechanism is configured to hold the lock hook in a forward resting position when the lock hook is not engaged with the pin. 4. The apparatus of claim 1, wherein the handle extension portion comprises a handle catch fixedly disposed on one or more sides of the handle extension portion, the handle catch configured to prevent the handle extension portion from moving relative to the first handle portion when the lock hook is engaged with the pin. 5. The apparatus of claim 4, further comprising: a catch pin disposed across the first handle portion and coupled to a latch release button, wherein: the latch release button is coupled to the lock hook;the catch pin travels along a second slotted hole disposed in the first handle portion and relative to the lock hook;the handle catch is configured to translate to a locked position;the catch pin is configured to translate to contact the handle catch in the locked position when the lock hook is engaged with the pin to keep the handle extension portion adjacent to the first handle portion; andthe catch pin is configured to translate away from the handle catch when the lock hook is not engaged with the pin to allow the handle extension portion to move away from the first handle portion. 6. The apparatus of claim 5, wherein the latch release button is configured to disengage the lock hook from the pin when the latch release button is depressed and the catch pin is configured to translate away from the handle catch when the latch release button is depressed to allow the handle extension portion to move away from the first handle portion. 7. The apparatus of claim 1, further comprising an adjustment nut disposed in the latch, configured to apply a selectable preload to the latch by adjusting a position of the latch relative to the pin. 8. The apparatus of claim 1, further comprising a first cowl member, a second cowl member, and the pin, wherein: the pin is disposed on the second cowl member;the latch is mechanically coupled to the first cowl member; andthe latch is configured to translate the first cowl member towards the second cowl member when the latch arm engages the pin. 9. An aircraft comprising the latch of claim 1, the aircraft further comprising: a first cowl member comprising a first cowl member outer surface, wherein the latch is mechanically coupled on the first cowl member;a second cowl member comprising a second cowl member outer surface; andthe pin disposed on the second cowl member, wherein the latch is configured to translate the first cowl member towards the second cowl member when the latch arm of the latch engages the pin and at least a portion of the bifold handle is configured to be flush with the first cowl member outer surface and/or the second cowl member outer surface when the lock hook is engaged. 10. The apparatus of claim 9, wherein a surface of the handle extension portion is configured to be flush with the first cowl member outer surface and/or the second cowl member outer surface when the lock hook is engaged and the handle extension portion is configured to move away from the first cowl member outer surface when the lock hook is not engaged. 11. A method of using a latch, the method comprising: moving a latch arm from a first position to a second position;securing the latch arm at the second position by engaging the latch arm to a pin;moving a first handle member, coupled to the latch arm, from a third position to the second position;securing the first handle member at the second position by engaging a lock hook, coupled to the first handle member, to the pin, wherein securing the first handle member comprises moving a catch pin, coupled to the lock hook, from a resting position to a center position responsive to engaging the lock hook to the pin;moving a handle extension member, coupled to the first handle member, into a secured position adjacent to the first handle member;securing the handle extension member at the secured position by the catch pin disposed at the center position; andwherein the handle extension member moves away from the first handle member when the catch pin moves from the center position to the resting position responsive to disengaging the lock hook from the pin. 12. The method of claim 11, wherein the latch arm comprises a latch hook and securing the latch arm at the second position comprises pulling the latch hook over the pin. 13. The method of claim 11, wherein the securing the first handle member comprises pushing the lock hook over the pin. 14. The method of claim 11, wherein securing the handle extension member by the catch pin comprises: moving, with a handle catch, the catch pin from the center position to the resting position;moving the handle catch from an unengaged position to an engaged position; andmoving the catch pin from the resting position to the center position. 15. The method of claim 11, further comprising: turning a nut disposed in the latch to adjust a preload of the latch arm. 16. The method of claim 11, further comprising: drawing together, with the latch arm, a first panel and a second panel. 17. The method of claim 11, further comprising unsecuring the latch, wherein unsecuring the latch comprises: moving the handle extension member from the secured position into an unsecured position;unsecuring the first handle member by disengaging the lock hook from the pin;moving the first handle member away from the second position;unsecuring the latch arm by disengaging the latch arm from the pin; andmoving the latch arm away from the second position. 18. The method of claim 17, wherein unsecuring the latch further comprises: depressing a latch release button, wherein depressing the latch release button moves the catch pin to a release position; andwherein the handle extension member moves away from the first handle member when the catch pin moves to the release position. 19. The method of claim 11, wherein the moving the first handle member comprises rotating the first handle member and the moving the handle extension member comprises rotating the handle extension member. 20. The method of claim 11, further comprising holding, by a first spring mechanism, the lock hook in a forward resting position when the lock hook is not engaged with the pin.
