Explained: Why Is Speed Tape Used on Aircraft Wings?

‍DALLAS — Speed tape is an aluminum pressure-sensitive tape primarily used for temporary, non-critical repairs on aircraft. 

While some passengers might mistake speed tape for regular duct tape, it has become an essential and recognized tool in commercial aviation maintenance. It provides a safe and efficient method for temporary repairs until more permanent solutions can be implemented.

Specifically, its design allows it to adhere effectively to surfaces at high speeds, where it gets its name. While it may resemble duct tape, speed tape is significantly stronger and thicker, making it suitable for high-stress applications.

Furthermore, despite its impressive strength, the tape is flexible enough to allow it to adhere to the shape of the treated surface (see video below), making it perfect for sealing cracks and fissures.

Also known as aircraft aluminum speed tape or High Speed Tape (HST), speed tape's unique properties make it ideal for aviation use:

• Material Composition: It is made from soft aluminum with a strong adhesive layer or as a multi-layer laminate that includes cloth.
• Temperature Resistance: It can withstand temperatures ranging from -65°F to 300°F, making it versatile for various environmental conditions.
• High-Speed Adhesion: It effectively sticks to aircraft surfaces during flight, even at speeds up to 600 mph.

Use in Commercial Aviation

Several factors drove the adoption of speed tape in commercial aviation:

• Temporary Repairs: Airlines began using it for minor or temporary repairs, allowing aircraft to continue flying safely until more permanent solutions could be implemented.
• Cost-Effective Solution: Speed tape provided a quick and cost-effective way to address minor issues without grounding aircraft for extended periods.
• Regulatory Compliance: Engineering teams authorized its use, which required compliance with specific aviation regulations, ensuring safety standards were maintained.

Over time, speed tape has become a standard tool in aircraft maintenance:

• Composite Aircraft Challenges: In recent years, airlines have used it to address issues with paint peeling on composite aircraft like the Airbus A350 and Boeing 787.
• Widespread Adoption: It is now commonly used across various airlines and aircraft types for temporary repairs and protection of aircraft surfaces.
