Selecting an Aircraft Management Company: A Due-Diligence Framework for Family Offices
Last updated: July 2026. Scope: European-based and internationally operated business aircraft.
Selecting an aircraft management company is not an ordinary procurement exercise. A family office grants extensive access to a valuable asset, sensitive travel patterns, substantial cash flows, crew decisions and safety-critical processes.
A low management fee, a large fleet or an impressive service proposition is therefore insufficient. Reliable selection criteria are clear accountability, appropriate approvals, effective safety and maintenance systems, transparent financial flows and independently verifiable performance.
The governing principle is straightforward:
Aircraft management delegates tasks, but it does not remove the owner’s and family office’s responsibility for governance, oversight and informed decisions.
The management company is not necessarily the operator
Aircraft management describes a bundle of services rather than a single regulatory function. A company may coordinate dispatch, crew, maintenance, accounting and charter sales without itself being the legal operator, AOC holder, CAMO or maintenance organisation.
In a European operating structure, the following roles should be distinguished.
Owner or aircraft SPV
The owner or dedicated aircraft special-purpose vehicle holds the asset. This entity is responsible for title, financing, shareholder decisions and the strategic objectives governing utilisation, holding period and eventual disposal.
Family office
The family office defines governance, budgets, approval processes and risk appetite. It coordinates the family’s interests and the work of aviation, legal, tax and insurance advisers.
Management company
The management company provides the administrative and operational coordination defined in the agreement. Its actual responsibilities depend on its contract, approvals and subcontracting structure.
Legal operator
The operator exercises operational control and is responsible for compliance with the applicable operating regime. The operator and management company may be the same entity, but they are not automatically identical.
AOC holder
The holder of an Air Operator Certificate may conduct commercial air transport within its specifically approved scope. An AOC held by a partner company cannot automatically be attributed to the company signing the management agreement.
CAMO
The Continuing Airworthiness Management Organisation manages the aircraft’s continuing airworthiness within its contracted and approved scope.
Maintenance organisation
An appropriately approved maintenance organisation performs and releases maintenance. Coordination by an aircraft manager does not replace the required technical approval.
Crew employer
The crew employer is responsible for employment contracts, remuneration, duty of care and essential personnel processes. It may be different from both the management company and the operator.
Charter sales company or broker
This entity markets available capacity, sources charter customers or brokers individual flights. Its commercial interests must be distinguished from the owner’s interests.
Several roles may sit within the same corporate group. Their legal allocation must nevertheless remain visible.
Every activity should be covered by a one-page responsibility map naming the legal entity, approval, decision rights, liability and insurance structure, and escalation path.
The current EASA Air Operations Rules distinguish, among other regimes, non-commercial operations with complex motor-powered aircraft under Part-NCC from commercial air transport. An Air Operator Certificate authorises specified commercial air transport operations. It is not a general quality endorsement covering every service offered by a corporate group.
International ownership, registration or operating structures may also involve the law of the state of registry, principal place of business, tax and customs treatment, import status, insurance and third-country operating permissions.
Selection begins with the target operating model
A defensible process starts with a target operating model approved by the family office, not with a list of management companies. It should define at least:
- ownership and financing structure
- private, corporate and potential commercial use
- expected utilisation, mission profile and operating regions
- required availability and acceptable maintenance windows
- principal base and alternative locations
- dedicated or pooled crew model
- privacy, security and data-protection requirements
- budget structure and approval authorities
- appetite for third-party charter
- expected holding period and aircraft exit strategy
Without this baseline, the family office will compare proposals that appear similar but contain different services, accountabilities and risk allocations.
Regulatory model and operational control
The candidate must clearly document the regime under which owner flights, corporate missions and any third-party charter will be conducted. The relevant party is not the brand named on the proposal but the legal entity exercising operational control.
Where charter is contemplated, the actual AOC operator, approved scope, aircraft onboarding path and commercial agreements must be identified. A generic statement that flights will use a partner AOC is insufficient.
Non-commercial operations also require clear accountability for the operator declaration, management system, manuals, crew, compliance monitoring and operational decisions.
Regulatory advice should remain separate from tax structuring. VAT, private use, transfer pricing, taxable benefits, import status and group structures require specific review by appropriately qualified legal and tax advisers.
Safety management rather than safety marketing
A current certificate is an entry requirement, not proof of an effective safety culture. The decisive evidence lies in how hazards are identified, reported, assessed and resolved.
Under the EASA Safety Management framework, effective management systems incorporate hazard identification, risk assessment, compliance monitoring, internal reporting, competence management and documented accountability.
A family office should review:
- the current scope and maturity of the Safety Management System
- the competence and independence of safety and compliance personnel
- anonymised safety reports and resulting corrective actions
- recurring audit findings and their underlying causes
- documented closure of findings
- management-of-change processes for a new aircraft, base or crew
- the Emergency Response Plan and date of the latest exercise
- decision-making around weather, fatigue, conflict zones and schedule pressure
A low reporting volume is not automatically positive. A completely silent reporting system may indicate weak trust or an immature just culture. The quality, handling and learning value of reports matter more than the raw number.
Voluntary IS-BAO registration can provide an additional signal. IBAC’s stages progress from established SMS infrastructure to fully integrated and sustained safety management. Registration complements regulatory approval but does not replace it. The family office should verify the audit date, stage, organisational scope, open findings and relevance to the aircraft concerned.
Continuing airworthiness and protection of asset value
A CAMO and a maintenance organisation perform different functions. The CAMO manages continuing airworthiness, while an appropriately approved maintenance organisation performs and releases maintenance. A management company may coordinate both functions without automatically holding either approval.
The EASA Continuing Airworthiness Rules provide the principal European framework. Due diligence should verify the approval scope, aircraft types covered, staffing capacity and contractual allocation of responsibilities.
The technical review should include:
- complete maintenance status and due dates
- Airworthiness Directives and relevant Service Bulletins
- engine, APU and component status
- engine and maintenance programme enrolment terms
- life-limited items and calendar-driven events
- known damage, repairs and modifications
- warranty and goodwill claims
- a maintenance forecast covering at least 24 to 36 months
- integrity and exportability of all technical records
- the effect of maintenance decisions on residual value and marketability
Aircraft records are part of the asset, not clerical output. Incomplete, inconsistent or non-exportable records can impair availability, airworthiness, financing and resale.
Crew governance and operational resilience
Crew quality affects safety, availability, discretion and the daily relationship between the owner and the management company. A family office therefore needs more than pilot résumés.
The review should cover:
- the legal employer and employment-law responsibilities
- dedicated or pooled crewing arrangements
- licences, medicals, type ratings and recency
- training standards beyond regulatory minima
- duty-time, rest and fatigue processes
- background screening and references
- remuneration, retention and turnover
- relief and succession planning
- protection of the commander’s authority
- clear limits on owner or schedule pressure
Personal service must never make operational limits appear negotiable. A mature organisation explicitly protects the crew’s authority to decline or alter a mission.
Operational resilience also requires continuous dispatch availability, international permissions capability, reliable handling partners, AOG procedures and a contractually defined replacement-aircraft solution.
Access to a large fleet does not by itself establish priority, availability, equivalence or price.
Financial transparency and conflicts of interest
The monthly management fee represents only a small part of the commercial relationship. A low base fee may be recovered through margins on fuel, maintenance, insurance, crew, handling or charter distribution.
A transparent model identifies:
- fixed management and administration fees
- direct and variable operating costs
- crew, training, hangar, insurance and CAMO costs
- engine, APU and maintenance programme charges
- calendar-based maintenance reserves
- foreign-exchange assumptions
- mark-ups, commissions, rebates and other benefits
- affiliated companies and related-party vendors
- spending and approval authorities
- owner ledgers, prepayments and reconciliation processes
The family office should be able to examine anonymised sample invoices, budget-to-actual variances and supporting records. Audit and inspection rights must be established contractually.
Charter revenue as a net contribution
Gross charter revenue is not owner benefit. The relevant measure is the net contribution after all incremental economic costs:
- positioning
- fuel and handling
- crew and accommodation
- brokerage and sales commissions
- additional hours and cycles
- engine and APU reserves
- maintenance, cleaning and cabin wear
- incremental insurance and compliance costs
- restrictions on owner availability
- potential effects on residual value and sale timing
Charter may offset part of the ownership cost, but it should not be presented as guaranteed return or complete cost coverage.
Owner priority, minimum pricing, customer acceptance, blackout periods and flight-by-flight approval should be defined in a written charter policy.
Privacy, information security and principal protection
An aircraft manager processes highly sensitive information, including passport data, destinations, passenger identities, travel patterns, preferences, medical details and financial records.
Where applicable, the European Part-IS framework requires systematic management of information-security risks that may affect aviation safety. For a family office, regulatory minimum compliance is only the starting point.
The review should also include:
- role-based access controls
- multi-factor authentication and access logging
- encryption and secure document transfer
- data minimisation and retention periods
- oversight of crew, handling, catering and IT providers
- privacy and cyber incident response
- protection of mobile devices and communication channels
- lawful measures to reduce unnecessary public visibility
- secure data return at the end of the mandate
Absolute anonymity cannot be promised in regulated aviation. A credible manager explains the legal limits and demonstrates effective protection within them.
Exit readiness as a quality criterion
A sound management relationship must be capable of ending in an orderly manner. Before signature, the family office should establish ownership of data, technical records, software exports, maintenance forecasts, crew files, contracts and system access.
The exit plan should cover:
- deadlines and formats for complete data delivery
- return of physical and electronic logbooks
- transfer of manufacturer and maintenance programmes
- transition of crew, hangar, insurance and suppliers
- support for a change of operator or CAMO
- final invoices, reserves and owner balances
- continuing confidentiality and data protection
- transition assistance without prohibitive additional charges
A company that offers transparency only while the contract remains in force creates dependency rather than trust.

Weighted scorecard
Candidates can be rated on a consistent scale from 0 to 5:
- 0: no evidence or information refused
- 1: predominantly informal and reactive
- 2: partly documented, with inconsistent evidence of implementation
- 3: documented and implemented in normal operations
- 4: measured, routinely tested and actively managed
- 5: independently evidenced and continuously improved
A suitable overall weighting is:
- 15 percent: regulatory model and accountability
- 15 percent: safety management and emergency readiness
- 15 percent: airworthiness, maintenance and asset protection
- 12 percent: financial control and transparency
- 10 percent: crew governance
- 10 percent: operational capability
- 8 percent: privacy, cybersecurity and security
- 7 percent: charter economics and conflicts of interest
- 5 percent: governance and reporting
- 3 percent: exit and transition
The weighted score for each category is calculated as:
Rating ÷ 5 × Weight
The scorecard creates comparability but does not override mandatory gates. A high aggregate score cannot cure unclear operational control or a missing approval.
Non-negotiable exclusion criteria
Regardless of the total score, the following should normally prevent appointment:
- unclear operational control
- unverifiable or unsuitable approvals
- absence of direct insurance confirmation
- refusal to provide technical or financial records
- undisclosed commissions or related-party transactions
- repeated audit findings without credible root-cause analysis
- no current Emergency Response Plan or practical exercise
- inadequate crew coverage
- no owner rights to records and data
- pressure to sign before due diligence is complete
Minimum controlled data-room contents
Before final selection, a secure data room should contain at least:
- Corporate and responsibility structure
- Relevant approvals, declarations and Operations Specifications
- Safety and compliance organisation
- Redacted audit reports and finding-closure evidence
- Emergency Response Plan and exercise record
- CAMO, maintenance and aircraft-records structure
- Current technical status and multi-year maintenance forecast
- Anonymised crew and training summary
- Insurance confirmation and principal coverage terms
- Complete budget model and sample invoices
- Procurement, commission and related-party policy
- Charter model including the net contribution waterfall
- Data-protection, information-security and vendor framework
- Sample reporting and KPI definitions
- Onboarding, termination and transition plan
Personal and safety-sensitive documents may initially be redacted and reviewed in greater depth after appropriate confidentiality arrangements are in place.
Minimum contractual standards
The management agreement should create control rather than merely list services. Core provisions include:
- precise scope and responsibility matrix
- spending and signature authorities
- budget process and variance tolerances
- audit, supporting-document and data-access rights
- vendor selection and disclosure of economic benefits
- approval of material subcontractors
- service levels and escalation deadlines
- crew safety authority
- insurance, liability and indemnity provisions
- charter policy and owner priority
- confidentiality, data protection and cyber incidents
- record ownership and data portability
- termination and transition assistance
Standard provisions require structure-specific review by aviation, corporate, tax, employment and insurance specialists.
Performance indicators for continuing oversight
Flight operations
Suitable indicators include dispatch reliability, delays, technical cancellations and Aircraft-on-Ground response time.
Technical performance
The family office should monitor unscheduled maintenance, deferred defects, maintenance-forecast variance and the time required to close technical findings.
Safety
Relevant indicators include the quality and handling of reports, status of agreed actions, recurring audit findings and the results of emergency exercises.
The target should not be to minimise safety reports. The objective is an active reporting system with timely assessment and effective follow-through.
Crew
Reporting should include training status, fatigue events, sickness and relief coverage, and turnover.
Financial control
Relevant indicators include budget variance, invoice cycle time, missing supporting documents, unapproved expenditure and foreign-exchange effects.
Charter
The central measure is the net contribution after all incremental costs, additional hours, cycles and owner-availability conflicts have been recognised.
Service
Useful indicators include response time, delivery of special requirements, complaints and completion of resulting corrective actions.
A defensible selection process
A professional process can be structured in seven phases:
- Mandate definition: mission profile, governance, risk appetite and target operating model
- Regulatory gate review: roles, approvals and operational feasibility
- Standardised request for proposal: identical scope and consistent cost definitions
- Controlled data room: evidence-based review rather than presentation comparison
- Management and scenario testing: response to AOG, crew illness, data breach and urgent itinerary change
- References and site review: comparable aircraft, mission profiles and owner structures
- Contract and transition: measurable performance, complete handover and a review after the first 90 to 120 days
References should provide more than confirmation of good service. Their value lies in evidence about budget variances, difficult maintenance events, safety findings, conflicts and previous management transitions.
Lohn Aviation as an owner-side adviser
An owner-side adviser does not begin by recommending a particular management company. The first task is to translate the family’s objectives into a defensible operating and governance model.
Lohn Aviation approaches the mandate as the link between the family office, owner, crew, technical organisations, operator, insurer, and legal and tax advisers. The role includes structuring the mandate, normalising proposals, testing interfaces and conflicts, and supporting contracting and onboarding.
The outcome must remain open. It may confirm the existing structure, support a management change, identify a different operating model or lead to a decision against aircraft ownership.
Advisory work creates trust only when remuneration and potential conflicts are disclosed. If the adviser or an affiliated company could itself perform an operational role, the same criteria, evidence requirements and decision rules must apply without modification.
Conclusion
The best aircraft management company is not necessarily the one with the most polished brochure, the largest fleet or the lowest base fee. It is the organisation whose accountability remains clear under pressure, whose decisions are documented and whose performance can be independently verified by the family office.
Trust in aircraft management is not created by proximity alone. It is built through clear roles, tested processes, transparent interests and the willingness to make difficult decisions on a defensible basis.
