While standing by for escort duty at San Fernando, 10 January 1946, Mack answering a distress call from FS-74, proceeded through heavy weather to the disabled ship's position. In the course of passing much needed food and water to the crew of FS-74, the two ships collided, causing damage to Macks bow (11 January). Mack returned to San Fernando and escorted the waiting ships to Subic Bay, remaining at Subic for three weeks undergoing repairs and holding drills.
