Which tool is used to perform a manual release on aircraft components?

• A. Manual Release Tool (MRT)
• B. Portable Oxygen Bottle (POB)
• C. OAL
• D. MEL

Answer: (A)

The idea is about having a dedicated way to unlock or disengage a mechanism when normal controls won’t operate. The Manual Release Tool is built specifically for this purpose, providing the correct tool geometry and safe engagement with release latches or mechanisms on aircraft components. Using the proper MRT ensures you can release the part without damaging hardware or compromising safety, and it’s the standard instrument provided for maintenance procedures that involve manual releases.

The other items don’t fit because a portable oxygen bottle is for supplying oxygen in an emergency, not for releasing mechanisms. OAL isn’t a tool used for releases, and MEL refers to the Minimum Equipment List, which is a document listing required equipment, not a physical tool.
