During scheduled maintenance of runway arresting gear systems, technicians must inspect the synthetic nylon purchase tape for structural wear and environmental degradation. The purchase tape must be removed from service immediately if the thickness drops below 0.28 inches or if edge fraying exceeds 0.5 inches. Furthermore, tape segments located within 15 feet of the runway centerline require ultrasonic integrity testing every 90 days due to friction and heat from landing aircraft tires.
According to the passage, which condition requires technicians to remove the purchase tape from service immediately?
- AThe tape segment is situated within 15 feet of the runway centerline
- The measured thickness of the tape falls below 0.28 inchesAnswer
- CThe tape completes 90 days of continuous runway deployment
- DThe tape absorbs direct heat from landing aircraft tires
Answer
The measured thickness of the tape falls below 0.28 inches
The passage explicitly states that the purchase tape must be removed from service immediately if its thickness drops below 0.28 inches (or if edge fraying exceeds 0.5 inches).
