3.7 Tool Control
The primary objective of a positive tool control program is to eliminate accidents/incidents and loss of life or equipment due to tool FOD.
There are numerous methods to facilitate accountability of tools (screwdriver, torque wrench, rivet gun, air hammer, clecos, etc.).  These include but are not limited to the use of tool inventory lists, shadow boards, shadowboxing, bar coding, special canvas layouts with tool pockets, tool counters, chit system, tool tags, or consolidated tool kits. Unique control methods should be implemented for special tools used in checkout, test and operational environments.
Tools/equipment should be tethered* or suitably restrained to the user in areas around structural work stands or any other locations where a dropped article could result in damage to flight hardware, injury to personnel, or where difficulty in retrieval would result if the tool were dropped. * NOTE: A tether device, if not regularly examined, may itself be the FO. Fraying of the tether material and the hardware (rings, snaps, etc.) can all become FOD.
All loose tools should be carried and stored in a tote tray, soft tool bag or other suitable spill- proof container and not be placed in a manner that would cause damage to flight hardware or injury to personnel.

Inventory all tools used in the area at the beginning/end of shift

All tools used in the area will be marked to identify source or origin

Broken tools or tools missing pieces will be reported in the FOD reporting system as Lost Tools.

Minimum Tool Controls for Area
FOD Awareness area controls:
– None

FOD Sensitive area controls:
– Inventory all tools used in the area at the beginning/end of shift
– All tools used in the area will be marked to identify source or origin 

FOD Critical area controls:
– Inventory all tools used in the area at the beginning/end of shift
– All tools used in the area will be marked to identify source or origin 
– Inventory tools and consumables before going onto the aircraft and after leaving the aircraft
– If employee leaves the aircraft for a period longer than 30 minutes, tools and consumables must be inventoried and taken off the aircraft
– When an employee completes work on one aircraft and moves to another aircraft, tools and consumables will be inventoried prior to working on subsequent aircraft

3.8 Hardware Control and accountability

The primary objective of hardware accountability is to assure control of loose hardware and parts.
There are many effective methods that can be established for control of hardware (nuts, bolts, screws, cotter pins, rivets, clecos, etc.):

– "Clean-As-You-Go."
– Kit hardware by task.
– FO containers should be placed in key locations within the work area and at entry and exit points.
