Definition
A Manufacturing Inspection District Office (MIDO) is a regional FAA field office responsible for overseeing aircraft, engine, propeller, and parts manufacturers within its assigned geographic area. MIDOs ensure that production approval holders comply with FAA regulations governing design and manufacturing, including type certificates, production certificates, and parts manufacturer approvals.
Plain English
A local FAA office that watches over aircraft and parts manufacturers in its region to make sure they build things to approved standards.
Context Anchor
Pilots may encounter MIDO in FAA acronyms, certification discussions, aircraft records, or paperwork connected with how an aircraft or part was manufactured.
Why Pilots Care
Most pilots will never deal with a MIDO directly, but it is part of the chain that ensures the aircraft they fly were built to FAA-approved standards. Knowing the term helps when reading certification documents or service difficulty reports.
Example Sentence 1
The aircraft manufacturer submitted its production paperwork to the local MIDO for review.
