Maintenance Program
• Tasks that need to be
accomplished to cost
effectively maintain safety and
ensure availability
• Main elements of each task:
– Item identified
– Activities specified
– Threshold
– Intervals
• Delivered with the aircraft
• Based on engineering analysis, assumptions & experience

1. Visually inspect the nose gear torque link pins and bushings for
excessive wear . Replace if beyond limits (see AMT-12-1900)
2. NDI inspect the attachment webs for cracking (see NDI-01-0067)
3. Threshold: 1,000 ldg cycles or 6 years
4. Repeat: 800 ldg cycles or 3 years

In Service Support - Maintenance
Maintenance Program
• Tasks are grouped
– Typically according to flying hours
(often a ‘common currency’)
– Consider: operations, inspection
locations and invasiveness

Real Product Structure
• Configuration state of each asset is dynamic
• Usage flows from top down
• Components that are lifed must be uniquely
identified and tracked
• Lifed components are replaced with new or
overhauled components (usage counter must
be reset)
• Components can and do move around among
assets

C130 Water Bomber
Crash – Walker, California
Probable Cause:
The inflight failure of the right wing due to fatigue
cracking in the center wing lower skin and underlying
structural members. A factor contributing to the accident
was inadequate maintenance procedures to detect
fatigue cracking.

Usage spectrum far more
severe than assumed –
fatigue cracking progressed
much quicker than
anticipated
