Definition
A manual published by an aircraft manufacturer that provides approved procedures, materials, dimensions, and limits for repairing the structural components of a specific aircraft. It identifies allowable damage, repair methods, and the conditions under which a repair may be performed without further engineering approval.
Plain English
The manufacturer's official book that tells mechanics exactly how to fix damaged parts of a particular aircraft, what materials to use, and what kind of damage is allowed without a major repair.
Context Anchor
Pilots usually encounter this term in maintenance discussions, aircraft logbook entries, damage inspections, or questions about whether an aircraft is still airworthy after structural damage.
Derivation
Structural comes from the Latin struere, meaning “to build.” In aviation, it points to the built parts of the aircraft that hold shape and carry forces. Manual simply means a book or set of instructions used to do a job correctly.
Why Pilots Care
Only repairs performed and documented according to this manual preserve the aircraft's airworthiness certificate and ensure continued safe operation.
Intuition Check
Do not read “manual” here as just any helpful repair guide. A Structural Repair Manual is approved manufacturer data for specific aircraft structural repairs, not a general maintenance handbook or a mechanic’s personal method.
Example Sentence 1
After the hangar rash dented the leading edge, the mechanic checked the Structural Repair Manual to see whether the damage fell within allowable limits.
Example Sentence 2
All work on the fuselage longeron was performed strictly per the Structural Repair Manual and signed off in the maintenance records.
