How should maintenance personnel assess surface damage on Low Observable coatings?

The assessment of surface damage on Low Observable coatings primarily relies on visual inspection of surface texture. This approach is essential because Low Observable technologies are designed to minimize radar return, and the effectiveness of these coatings is closely linked to their surface condition. During a visual inspection, maintenance personnel can identify irregularities such as scratches, abrasions, or any deterioration of the coating that could affect stealth performance.

Visual assessments allow personnel to determine the extent of damage and whether it necessitates repair or replacement. Looking for changes in the texture or appearance can reveal crucial information regarding the integrity of the coating, which is vital for maintaining the aircraft's low observability features.

Other methods such as radar detection, chemical tests, or even measuring the aircraft's weight, while potentially useful in broader assessments, do not directly evaluate the state of Low Observable coatings as effectively as a thorough visual inspection.
