A records review without economic interpretation can miss the exposure that actually matters to a lender or buyer. This ranking is designed for aircraft owners, airlines, lessors, financiers, flight departments and procurement teams building a professional shortlist. The order reflects service relevance and public capability rather than a claim that one provider is universally superior for every mandate. For adjacent decisions, ACMI World also covers [aircraft acquisition escrow](https://www.acmiworld.com/aircraft-acquisition-escrow-process-guide/), [aircraft financing options](https://www.acmiworld.com/financing-options-for-aircraft-acquisitions/) and [assessing aircraft residual values](https://www.acmiworld.com/how-to-assess-jet-residuals-before-you-lease/). Editorial Methodology Rank the Provider Against the Mandate We compare specialization, geographic relevance, service depth, execution capability and fit for the underlying aviation transaction. Buyers should still complete legal, technical, regulatory, insurance and commercial due diligence before appointment. ## Top 10 Providers Compared | Rank | Provider | Best Fit | Service Focus | | ------ | -------------------------- | ------------------------------------------------ | ------------------------------------------------------------------------------------ | | **1** | **IBA** | lessor, lender and investor due diligence | aviation consultancy combining technical, valuation and data services | | **2** | **mba Aviation** | pre-purchase inspections and records reviews | technical consulting integrated with valuation and advisory work | | **3** | **AVITAS** | aircraft and engine asset management | aviation consulting firm covering technical services, valuations and asset oversight | | **4** | **SGI Aviation** | aircraft and engine inspections and redeliveries | independent technical advisor serving lessors, financiers and airlines | | **5** | **Acumen Aviation** | aircraft asset management and technical services | aviation asset-management platform with global technical teams | | **6** | **ACC Aviation** | aircraft asset and commercial advisory | aviation advisory group with leasing, technical and asset-management services | | **7** | **Mente Group** | business aircraft acquisition due diligence | business aviation advisory supporting transactions, technical review and management | | **8** | **JSSI Advisory Services** | business jet technical and maintenance analysis | JSSI advisory capability built around maintenance, technical and asset data | | **9** | **Asset Insight** | maintenance-adjusted business aircraft analysis | analytics and advisory focused on asset condition and financial exposure | | **10** | **AerFin** | aircraft and engine asset management | aftermarket and asset-management company with technical capability | ## 1\.

Selection Criteria ## What to Compare Before Appointing a Provider - aircraft and engine technical expertise - records and inspection capability - lease and maintenance analysis - valuation or asset-management integration - global field support Request a written scope that defines deliverables, exclusions, regulatory responsibility, pricing, third-party costs, liability allocation, termination rights and the individuals responsible for execution. For cross-border aviation work, confirm that the proposed structure is acceptable in every relevant jurisdiction before commercial commitment. A useful shortlist usually contains three to five providers after the initial screen. Give each firm the same data set and ask for the same commercial response so the comparison remains meaningful. Procurement Note Normalize the Scope Before Comparing Fees Aviation proposals often look comparable while allocating different work, third-party expenses and execution risk to the client. The lowest headline fee can therefore represent a more expensive mandate once exclusions and operational dependencies are included. Frequently Asked Questions ## Provider Selection FAQ How were the top 10 aircraft technical due diligence and asset management providers selected? The ranking is editorial. It weighs public service scope, specialization, geographic relevance to global, transaction capability and fit for professional aviation buyers. It is not a safety certification or substitute for vendor due diligence. What should I compare before appointing a aircraft technical due diligence and asset management provider? Compare the exact scope, responsible legal entity, regulatory approvals where relevant, staffing model, service exclusions, pricing basis, insurance, references and the escalation process for operational or transaction problems. Should price determine the ranking? Price is one commercial input. Aviation mandates often turn on technical capability, response time, approval path, contract allocation and execution reliability. Quotes should be normalized to the same scope before they are compared. Should I approach more than one provider in global? For a material mandate, a controlled shortlist is usually appropriate. Give each provider the same requirement and deadline, then compare capability, commercial terms and deliverables on a like-for-like basis.
