Lease rate and maintenance cost: estimates for ownership and upkeep

If you do not enter your own rates, the calculator uses estimates from weight and seat count. These are parametric, not operator data: each one can be replaced in the calculation.

Maintenance by year — US carriers' reports (Form 41)

Maintenance cost per block hour as reported by US carriers flying this type: direct (labour, materials, outside services) and full — with the maintenance department's overheads. Dollars of each year, not restated. 2020 stands above its neighbours: flying dropped, the fixed part of the cost stayed.

2025: direct USD 1,794, with overheads USD 2,485 per block hour, 2 carriers
