GSE Preventive Maintenance Interval Workload at 46% parts, access, and findings allowance: a worked example

What does the result look like when parts, access, and findings allowance reaches 46%? The full calculation is worked below with real intermediate numbers. a GSE maintenance manager needs to schedule PM labor without reducing ramp equipment availability

The inputs for this scenario

  • GSE units due for preventive maintenance: 58 units (unchanged)
  • PM completion pace: 0.11 units/min (unchanged)
  • Parts, access, and findings allowance: 46 % (raised for this scenario; the documented default is 40)

Working through the calculation

  • Applying the documented formula (Base PM workload = GSE units due for preventive maintenance รท PM completion pace, converted to hours) to the inputs above produces each figure below.
  • At this operating point the engine returns 770 PM labor hr for total gse pm workload, the number this scenario is built around.
  • At this operating point the engine returns 527 PM labor hr for base pm workload.
  • At this operating point the engine returns 46 % for parts, access, and findings allowance.
  • At this operating point the engine returns 0.11 units/min for pm completion pace.

How this compares with the baseline

  • Against the tool's baseline example, where parts, access, and findings allowance sits at 40% and the headline result is 738 PM labor hr, this scenario comes in 4.29% above the baseline at 770 PM labor hr.
  • A figure at this level is achievable when parts, access, and findings allowance is genuinely sustained, not just peaked for a shift. A single completion pace blends quick small-GSE inspections with heavy diesel tug services, so split by equipment class when the fleet is mixed.

Results at a glance

  • Total GSE PM workload: 770 PM labor hr (headline result)
  • Base PM workload: 527 PM labor hr
  • Parts, access, and findings allowance: 46 %
  • PM completion pace: 0.11 units/min
