Detailed information on more complex and specialized subjects, such as Structural Wiring Diagrams or Overhaul Information, may  either  be included in the basic Maintenance Manual or made available as separate documents at the option of the manufacturer and to the extent the manufacturer  determines appropriate. When published as separate documents, the format of Paragraph 19 or  that  of  Air Transport Association of America Specification No. 100 shall be used.

Any technical data published in the ATA No. 100 format will meet the requirements of  this  specification although  it is expected that the Paragraph 19 format will be used where no ATA-100 requirement is foreseen.
