Unsafe Condition
OHDS sensing elements that do not properly detect thermal bleed leak events, which could result in an air leak remaining undetected by the OHDS at an affected position and not being isolated during flight, possibly resulting in localized areas of the main landing gear bay and keel beam being exposed to high temperatures, and consequent reduced structural integrity of the airplane.
