positioned for rapid and simple inspection and recognition of
e x c e s s i v e wear or potential failure.
c. Permit adjustments, servicing, replacement of parts and components
and other maintenance with minimum disturbance to other equipment parts or
or components. Parts and components shall be located for ample and rapid

items cannot be avoided, the item predicted to require the most
m a i n t e n a n c e shall be located for best accessibility.
d. Permit maintenance with general purpose tools and equipment normally
available commercially. Use of special purpose tools and equipment shall
be subject to approval of the procuring activity.
e. Minimum number of tools required for maintenance by design practices
such as reducing the variety of bolt head sizes to the practicable

f . Foolproofness - Where improper Installation of an item could cause a
malfunction of the item or the equipment in which It is installed, an
unsymmetrical mounting means shall be provided where practical. That
mounting shall allow the item to be installed only in its proper operating
position.
If an unsymmetrical mounting means is not practical, the item
shall be so mounted that Its proper operating position can be readily and
visibly determined by service maintenance personnel.
