Section VI. UNIT MAINTENANCE PROCEDURES
MGB primary components are highly stressed and early detection of crack damage is most
Important. Delay in detection of cracks may result in complete failure of a component.
All components must be cleaned and inspected at regular intervals. If any cracks or damage are noted, items
must be repaired at authorized level of maintenance.
Periodic inspection by an authorized inspector will be carried out at regular intervals. Visual inspection of all
bridge and launching components will be made following each bridge mission.
Refer to Unit Preventive Maintenance Checks and Services (Section IV) for inspection procedures.
During inspections, pay particular attention to all welds, top and bottom chords of highly
stressed components and all connectors and lugs.
