A locking method for a detachable cargo mirror assembly, the detachable cargo mirror assembly comprising:

• a bracket for mounting to a surface on a rotorcraft, the bracket comprising a base portion and a retainer portion having a first pair of opposing holes;
• an elongated arm having two opposing ends, a first end for coupling with the bracket and a second end coupled to a mirror apparatus, the first end having a passage;
• and
• a releasable connector that engages with the first pair of opposing holes and the passage in the elongated arm when the elongated arm is in a first position to display a desired image on the mirror apparatus;
• wherein the retainer portion further comprises a second pair of opposing holes for engagement with the releasable connector when the elongated arm is in a second position for stowage;
• the locking method comprising the steps of:
• engaging the first end of the elongated arm in the retainer portion of the bracket;
• aligning the second pair of opposing holes with the passage in the elongated arm;
• engaging the releasable connector in the second pair of opposing holes and the passage in the first end of the elongated arm;
• and
• maintaining a locked configuration by use of a protrusion proximate one of the second pair of opposing holes;
• wherein the protrusion extends beyond a diameter of one of the second pair of opposing holes.
