Tools, Cartridges and Gadgets: What’s Now Allowed on Planes

Introduction

When the TSA was established post-9/11, its primary goal was to enhance aviation safety. Over the years, advancements in scanning technology, detection methods, and training protocols have led to the evolution of rules regarding what passengers can bring on board. The TSA continually balances passenger safety with limited resources, occasionally allowing items that were once prohibited.

Tools and Multi-Tools

• Pre-2005: Tools were completely banned in airport and cabin areas.
• Post-2005: The TSA lifted the blanket ban after discovering nearly half a million tools in the first six months of the year.
• Current Rules:
• Tools shorter than seven inches are allowed in carry-on bags.
• Scissors with blades no longer than four inches are permitted.
• Larger knives, including common Swiss Army knives, must be placed in checked luggage.
• Some multi-tools comply with the new size limits and are allowed.

Printer Cartridges

• 2010 Incident: Authorities in Britain and the UAE found two printer cartridges converted into improvised explosive devices on flights to Yemen.
• Initial Response: The TSA prohibited cartridges over 16 ounces in both carry-on and checked bags.
• Current Rules: With improved detection technology, cartridges are now allowed if they pass standard screening checks.

Large Personal Electronics

• Temporary Restrictions: Intelligence suggested that bombs could be hidden in laptops and tablets, especially after a bomb detonated on a Somali flight that landed safely.
• Affected Airlines and Airports: The ban targeted specific airlines and departure airports, including carriers from Kuwait, Saudi Arabia, Turkey, and others.
• Concerns: The ban raised worries about data loss, theft, and the fire risk of lithium-ion batteries in cargo holds.
• Resolution: New screening methods were installed at the affected airports, leading to the lifting of restrictions. Electronics can now travel in cabin luggage.

Conclusion

These examples illustrate how security policies evolve with new information and better technology. Items that were once deemed dangerous are now allowed when they can be safely detected and monitored.
