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?
