What additional work does fractional ownership require?

Treat fractional ownership as an asset-and-service commitment, not a discounted hourly rate.

Part 91 Subpart K contains specific management-contract and operational-control provisions. Counsel should explain the owner’s responsibilities, not just the provider’s service promises. (ecfr.gov)

Follow this sequence:

1. Validate the mission portfolio. Establish aircraft needs, annual usage, peak dates and simultaneous-aircraft requirements.
2. Request the complete transaction set. Include any purchase or lease, management, exchange, financing and repurchase documents.
3. Build a full-term cash-flow model. Include capital, fees, usage charges, adjustments, supplemental charter, exit costs and timing.
4. Review ownership and operating responsibilities. Engage aviation counsel, tax counsel and the insurance adviser before signing.
5. Test exit scenarios. Model planned exit, earlier exit, lower resale proceeds and delayed settlement.
6. Complete legal and financial approval before funding. Reconcile the signed commercial terms to the model.

NetJets’ pricing explanation separately identifies share acquisition or leasing, monthly management fees, occupied hourly fees and a variable fuel rate. Use the actual provider’s documents to populate the model rather than assuming all programmes have identical inclusions. (netjets.com)

A proposed economic comparison is:

full-term economic cost = acquisition price − net exit proceeds + financing/capital cost + recurring fees + usage charges + other costs

Also show actual cash-flow timing. Do not count both the full acquisition payment and depreciation as separate economic costs in the same comparison. Have finance validate the treatment and keep tax assumptions in a separately reviewed schedule.

There is no universal annual-hours threshold in this playbook. The model should demonstrate the result for your routes, terms and utilisation.
