Aerospace Rework Hours Calculator

Estimate labor for a defined group of rework units. Enter hands-on rework and reinspection hours per unit, plus the shared setup effort.

What this calculator does

  • Estimate labor for an approved rework plan, including reinspection and job setup.

Formula used

  • Rework labor = rework units × rework hours per unit
  • Reinspection labor = rework units × reinspection hours per unit
  • Total rework labor = rework labor + reinspection labor + setup labor

Inputs explained

  • Units Requiring Rework: Units assigned to this approved, comparable rework route.
  • Rework Labor per Unit: Recorded or estimated hands-on labor for the approved rework steps.
  • Reinspection Labor per Unit: Labor needed to verify each reworked unit against its requirements.
  • Rework Setup Labor: Job-specific preparation labor incurred once for this rework group.

How to use the result

  • Best suited to approved rework labor Plan, recovery staffing estimate.
  • The estimate does not approve a rework or disposition nonconforming hardware. Waiting, engineering disposition and material lead time are outside labor hours.

Current U.S. benchmarks

  • Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
  • The U.S. has 11,691 transportation equipment establishments employing about 1,682,910 workers (Census County Business Patterns, 2023).

Common questions

  • Why is accepted rework yield absent? Yield does not erase labor already spent on an unsuccessful rework. Estimate work performed, then track accepted units separately.
  • Does this tell me how much work the team can finish? No, it estimates required labor. Compare that workload with the qualified labor available in your scheduling window.
  • Should engineering disposition time be included? Add it to a separate planning activity unless it is already part of the entered labor scope. Approval waiting time is not hands-on rework effort.
  • Can setup remain when no units require rework? Yes, the entered setup effort remains. Set setup to zero too when no preparation work will occur.
