My Scratch Drawing Checklist

Metal part drawing checklist – this list is not comprehensive. Any and all errors will not be tolerated whether they are on this list or not.

Title Block

  • Is the drawing title correctly formulated? (Typically major to minor i.e., AILERON SYSTEM, BELLCRANK, OUTBOARD, LH)
  • Is the drawing number correctly formulated?
  • Is the material correctly specified?
  • Is the stock size correct? (Did you check with procurement?)
  • Is a heat treat required?
  • Is the corrosion protection correctly specified?
  • Have you checked all the interfacing components and hardware to make sure that the corrosion protection is correct?
  • Are there any other coating/priming/painting processes that should be applied at the part level?
  • Has the grain direction been defined?

Views

  • Have you included enough projected views, sections and details to fully and correctly define the part?
  • Have I included views that are not needed or do not add clarity?
  • Is every key feature dimensioned correctly”
  • Have I used the correct number of decimal places so the appropriate level of tolerance is defined?
  • Have I specified custom tolerances where required?
  • Have I used custom tolerances where they are not required?
  • If I have included a reference dimension (in brackets) why is it needed? – the CAD can always be used for reference
  • Is the location of the part number rational? You may have to check the upper assemblies to ensure it remains visible at installation.

Datums

  • Do they make sense for manufacture?
  • Do they make sense for the quality inspection?
  • Have you used datums that are accessible and can be used for measurement?

Drawing Notes

  • Is the general note for using the E-Model included
  • Are notes included that define all the critical aspects of the part
  • Are there any special inspections or quality checks required? Do not assume that manufacturing or quality know anything about the part.
  • Are there any special storage requirements between part manufacture and installation in the aircraft?
  • Is there anything else we should be communicating?

Revision table

  • Is the description of the change sufficient?
  • Is the date correct
  • Is the effectivity included and correct?

Other

  • Have I included a second sheet to the drawing when there was room for everything on the first sheet?
  • Have I added a second sheet because it is required to maintain clarity?
  • Do arrow, pointers, dimension lines pass through each other?
  • Do arrow, pointers, dimension lines pass through any text?
  • Does an element of the drawing come very close to or pass over the drawing border frame?
  • Have I done my job?
  • Will Manufacturing be laughing at me behind my back because my name is on this drawing?
