A service relationship, not a transfer of every duty
An aircraft management company can coordinate crew, maintenance, scheduling, insurance administration and financial reporting. That does not mean every legal responsibility automatically transfers to the manager. The owner, operator and specialist organisations can each retain distinct duties. The agreement should identify which entity operates the aircraft, who controls flight decisions and which tasks the manager performs directly or through subcontractors.
Begin with the intended use. An owner-only aircraft, a commercially operated charter aircraft and an aircraft used under a fractional arrangement can sit within different regulatory structures. In relevant European operations, EASA Part-NCC addresses noncommercial operations with complex motor-powered aircraft. In the United States, FAA Part 91 and Part 135 serve different operating contexts. A manager should explain the applicable structure in plain language rather than implying that management alone authorises commercial flying.
Crew planning is a continuing commitment
Crew provision involves more than finding people for departure day. Recruitment, type qualifications, recurrent training, leave, medical validity and duty limitations all affect availability. An aircraft can be technically ready yet unavailable because the crew cannot legally or practically perform the mission. Owners should ask how the manager plans cover, what qualifications are required for replacement crew and how additional staffing costs are approved.
There should also be an unambiguous route for reporting safety concerns. Commercial pressure, a tight diary or an important passenger must not blur the crew's operational authority. Ask how scheduling decisions are separated from safety decisions, and whether the owner receives understandable reporting on operational limitations. A professional “not today” can be evidence of a functioning system rather than poor service.
Maintenance coordination and technical records
Scheduled inspections, component limits and unplanned defects shape aircraft availability. The manager may organise maintenance slots, monitor due items and coordinate approved maintenance organisations, but the exact responsibilities depend on the jurisdiction and contract. In Europe, continuing airworthiness management and maintenance approval are distinct concepts; an EASA Part-145 approval concerns a maintenance organisation, not a blanket authorisation for every management activity.
Ask who keeps the technical records, how access is maintained and what happens to those records if the relationship ends. Well-organised records support compliance, maintenance decisions and future transactions. The owner should understand the forecast downtime calendar and the procedure for an unexpected defect away from base. A reserve budget is useful, but it cannot make an unavailable component arrive immediately or guarantee a maintenance completion date.
Build a budget that separates the moving parts
Management proposals often include a recurring fee, but that figure is only one part of the operating budget. Crew employment, training, hangarage, insurance and subscriptions may continue regardless of flight activity. Fuel, handling and certain maintenance expenses vary with use. Larger inspections and component events may arrive unevenly, making a smooth monthly average a poor description of cash requirements.
Request a clear policy for supplier markups, purchasing rebates, expenses and approval thresholds. Ask whether the manager receives commissions or other benefits from recommended suppliers. Reporting should distinguish estimates from invoices and identify commitments not yet billed. Compare the transparency of the accounting process, not merely the management fee. Tax, ownership structure and asset financing require appropriately qualified advice; a general operational proposal is not a substitute.
Charter availability introduces a second priority
Some owners make their aircraft available for charter through an appropriately authorised operator. Revenue may offset some costs, but the aircraft is not a guaranteed income-producing asset. Demand, aircraft location, owner use, maintenance and crew availability all influence what can actually be sold. Additional flying also produces variable costs, wear and possible scheduling conflicts.
The agreement should establish owner priority, minimum notice, excluded destinations, pricing authority and the treatment of positioning flights. Ask how gross revenue becomes the net amount credited to the owner. If a proposal relies on optimistic charter utilisation to appear affordable, test a lower-demand scenario. The decision to own should remain understandable without assuming that every available day will generate a profitable trip.
Evaluate the system and plan the exit
The International Business Aviation Council's IS-BAO framework addresses business aircraft operational practices. It can inform a conversation about management systems, but a standard or registration is not a guarantee of a particular outcome. Ask what evidence supports the manager's statements, what the assessment scope covers and how findings are handled. The UK Civil Aviation Authority, FAA and EASA provide regulatory context appropriate to their respective responsibilities.
Finally, discuss the end of the relationship before signing. Notice periods, employee arrangements, outstanding invoices, technical-record transfer and access to operational data can make a transition difficult if left undefined. A good agreement explains not only how the service begins, but how the owner can leave without losing visibility over the aircraft. Clarity during an ordinary month is the best preparation for a difficult one.
