• (a) a striker pin configured to be coupled to a doorframe of the aircraft;
• and
• (b) a catch assembly, wherein the catch assembly includes:
• (i) a housing configured to be coupled to the door of the aircraft, wherein the housing includes:
• (A) a rectangular aperture,
• (B) an indicator strip proximate the rectangular aperture,
• (C) a C-shaped recess configured to selectively receive the striker pin, and
• (D) an upper support pin extending through the housing, and
• (ii) a catch pivotably coupled to the housing about the upper support pin, wherein the catch includes:
• (A) a U-shaped recess configured to selectively receive the striker pin, and
• (B) a hook configured to extend at least partially through the rectangular aperture, wherein the hook includes an outboard surface configured to selectively cover the indicator strip,
• wherein the catch is pivotable relative to the housing between at least an open orientation, a security orientation, and a locked orientation,
• wherein in the open orientation the indicator strip is revealed and the U-shaped recess is oriented to face at least partially laterally inwardly relative to the longitudinal axis of the aircraft,
• wherein in the security orientation the hook partially conceals the indicator strip and the U-shaped recess is oriented to face less laterally inwardly and more upwardly compared to the open orientation, and
• wherein in the lock orientation the hook conceals the indicator strip and the U-shaped recess is oriented to face upwardly and to coincide with an axis defined by the C-shaped recess, wherein the striker pin is received by the C-shaped recess and the U-shaped recess in the lock orientation.
