Five Key Questions to Ask When Vetting a Part 91 Aircraft Management Provider

Aviation industry guidance identifies five areas owners should examine when vetting a Part 91 aircraft management provider, framing the choice as a governance decision rather than a vendor comparison because under Federal Aviation Regulations Part 91 the aircraft owner or lessee is the operator of record, meaning the FAA, insurers and lenders hold that party responsible first when something goes wrong. Experts recommend building a shortlist of three or four candidates and putting each through the same structured questions.

The first area is operational control: owners should ask whether the proposed arrangement leaves control with them or requires placing the aircraft on the provider's operating certificate, since a Part 135-style arrangement shifts operational control, the maintenance program and crew duty rules to the certificate holder. Under the FAA's fractional rules as codified in the eCFR, an owner in operational control of a program flight remains ultimately responsible for safe operations and compliance with all applicable requirements. The second area, back-office scope, covers 24-hour flight coordination, scheduling and dispatch, flight following, crew coordination, trip logistics, vendor and FBO management, fuel planning, compliance documentation and financial oversight of trip costs, with any service not explicitly named remaining the owner's responsibility.

On safety certifications, providers should produce the registration or audit certificate, the date of the last audit, the auditing organisation's name, and shareable findings with a corrective-action plan; IS-BAO registration, ARGUS ratings and WYVERN Wingman designations carry weight only with a current date and a finding list, and for operations running one to five aircraft a written safety management system with documented risk assessments is described as the minimum acceptable standard. On crew quality, because Part 91 sets no statutory flight-time, duty or rest limits for non-commercial operations, owners should ask who verifies crew legality before a trip, what training standard applies, and who holds final authority to decline a leg, with acceptable answers including simulator-based recurrent training at a named provider, tracked duty limits with specified hours, and a stated policy giving the pilot-in-command authority to decline a leg without owner approval.

On compliance and records, owners should confirm who holds and updates records, which maintenance-tracking system is used and in whose name the subscription sits, and what the response protocol is in the first hour of an aircraft-on-ground event; the tracking subscription should be in the owner's name with the owner's own login, since a subscription held in the provider's name means the owner loses the history upon contract termination. Maintenance forecasts should include 30-, 60- and 90-day look-aheads plus current airworthiness-directive and service-bulletin status. The FAA has identified enforcement of illegal charter operations as an active priority, particularly in Florida.

This guidance reflects a structural feature of Part 91 management: because the regulation places no statutory duty, rest or flight-time limits on non-commercial operations, and because the owner remains the operator of record, every layer of protection an owner actually has comes from contract language and internal provider procedure rather than from the regulation itself. That is why the recommended questions target documentation — audit dates, finding lists, look-ahead maintenance forecasts, login ownership — instead of asking providers to describe their general capability.

The segment works on a similar logic to other outsourced-management arrangements: the closer a provider's proposal edges toward assuming operational control, the more it resembles a Part 135 certificate holder relationship, with different liability and compliance consequences. Providers who self-identify the limits of their model and refer prospective clients elsewhere when the fit is wrong are described as generally more credible than those claiming to handle everything, which suggests the market rewards precision about scope over breadth of promised service.

With enforcement of illegal charter operations named as an active FAA priority in Florida, per-flight documentation of who holds operational control becomes an ongoing requirement rather than something settled once at contract signing. Owners weighing a shortlist of three or four candidates should expect that the answer to who verifies crew legality, who owns the maintenance-tracking login, and who can decline a leg will matter as much on flight two hundred as on flight one.
