What sets it apart
Forecast engine fleet maintenance cost
Connect aircraft engine, APU, and landing gear availability and usage data directly to lifecycle cost forecasts.
Model what-if engine planning scenarios
Model spare, lease, exchange, and contract strategies before decisions are made.
Link engine removals to maintenance cost
Translate engine, APU, and landing gear removal timing into forecasted maintenance cost and budget impact.
Plan across multiple engine types
Support planning across mixed fleets and multiple engine, APU, and landing gear types.
Generate engine forecast reports
Generate structured maintenance cost forecasts and reports across engine, APU, and landing gear.
Boeing expertise
Built on decades of Boeing engine, APU, and landing gear management experience.
Product overview
Boeing Engine Fleet Planning and Costing combines predictive forecasting with financial modeling to plan maintenance events, contract strategies, and lifecycle cost across the fleet.
Slide 1 of 1
Removal and shop visit forecasting
Predict aircraft engine, APU, and landing gear removals and shop visits using forecasting models and usage data. See when assets will likely require removal and what each event will cost. Plan ahead with clear visibility into timing, scope, and financial impact, enabling more coordinated maintenance planning and fewer last-minute decisions across the fleet.
Slide 1 of 1
Contract and scenario modeling
Model Power-by-the-Hour, Time and Materials, lease, exchange, and spare strategies using airline-defined inputs. Translate those assumptions into lifecycle cost projections before capital is committed. Compare multiple scenarios side by side to understand cost, risk, and long-term financial outcomes, supporting more informed decisions before entering agreements or committing capital.

Spare pool simulation
Simulate spare engine sizing across the fleet. Evaluate how different pool strategies affect capital and risk. Identify the right balance between spare availability, cost efficiency, and operational resilience, ensuring coverage without over-investing in underutilized assets.

Lease return planning
Track aircraft engine lease terms and condition against forecasted removals. Identify financial exposure early. Plan maintenance timing and scope to avoid penalties, reduce unnecessary work, and minimize disruption as engines approach lease return conditions.

Unified technical and financial view
Integrate engine availability, maintenance records, and contract data into one structured planning environment for maintenance and finance teams. Connect technical events directly to financial outcomes. Ensure decisions are made using consistent, shared data across the organization, improving alignment and reducing discrepancies between engineering, operations, and finance.
System integrations
Maintenance and engineering systems such as AMOS and TRAX
ERP and finance platforms such as SAP
Airline data warehouses and financial planning systems
Internal fleet and engine planning platforms
Why airlines choose EFPAC
EFPAC is a financial control system designed to prevent maintenance cost exposure before it occurs and give airlines confidence in long-term lifecycle spend. Airlines invest in EFPAC to replace reactive decisions with structured, forward-looking financial planning across the fleet.
Prevent unplanned maintenance cost exposure
Forecast engine, APU, and landing gear removals and financial impact before capital is committed, reducing unexpected spend and operational disruption.
Control long-term maintenance spend
Stabilize maintenance budgets by connecting technical events directly to financial outcomes, improving predictability across the fleet.
Optimize capital allocation
Avoid over-investment in spare assets and unnecessary shop visits through accurate forecasting and scenario-based planning.
Make contract decisions with financial clarity
Evaluate maintenance contracts and lease strategies based on lifecycle cost impact before committing to long-term agreements.
Align maintenance and finance around one plan
Provide a single, structured forecast that connects engineering, operations, and finance teams to the same financial outlook.
Deliver payback in as little as 12-24 months
Airlines using EFPAC reduce lifecycle maintenance cost and may achieve payback within 12 to 24 months.
Frequently asked questions
What is EFPAC?
EFPAC is Boeing’s Engine Fleet Planning and Costing system that integrates technical, operational, and financial inputs to forecast aircraft engine removals, shop visits, and lifecycle cost. Besides engines, the tool also handles APUs and landing gear.
How does EFPAC forecast aircraft engine shop visits?
EFPAC uses aircraft engine usage data and contract assumptions to project removals and shop visits years in advance, supporting proactive maintenance and financial planning.
Can EFPAC model Power-by-the-Hour and Time and Materials contracts?
Yes. EFPAC models Power-by-the-Hour and Time and Materials scenarios using airline-defined inputs to show lifecycle cost impact before capital is committed.
Does EFPAC support Unscheduled Engine Removals?
Yes. EFPAC models UER probabilities, anticipates for these events, and provides a mitigation scenario with recommendations.
