What is the maximum acceptable delamination of a windshield before a write-up is necessary?

• A. One inch from the edge
• B. Two inches from the edge with four inches in corners
• C. Three inches from the edge
• D. Four inches from the edge

Answer: (B)

The correct answer is based on the specific maintenance standards for aircraft windshields. Delamination refers to the separation of layers in a laminated windshield, which can compromise the structural integrity and transparency necessary for safe operations. The standard allows delamination up to two inches from the edge of the windshield with an additional allowance of up to four inches in the corners. This is because corner areas may be subjected to different stress factors, and a slightly larger tolerance is provided there. This specification ensures that the pilot’s visibility remains clear and that there are no immediate safety concerns regarding the integrity of the windshield. By adhering to this standard, maintenance crews can effectively manage issues of delamination while still prioritizing safety. If the delamination exceeds these thresholds, it would necessitate writing up the issue for further inspection or replacement.
