What is typically found using microfiche in an aircraft maintenance context?

In the context of aircraft maintenance, microfiche serves as an archival medium for storing and accessing large volumes of documents in a space-efficient manner. Typically, rows of images of printed documents are found on microfiche. These documents can include maintenance manuals, wiring diagrams, service bulletins, and other important technical documentation crucial for the maintenance and repair of aircraft.

Microfiche was widely used before the advent of digital storage solutions and continues to serve as a reliable resource for accessing historical maintenance data. Technicians can use a microfiche reader to view the documents archived on the microfiche, which provides an efficient way to retrieve information that may no longer be easily available in paper form or may not yet be digitized. This visual format allows maintenance personnel to read and analyze technical data necessary for ensuring the safety and functionality of aircraft.
