A Lot to Maintain.
Maintaining a business jet can be a challenging, complex, and expensive responsibility.
It is not a job that should ever be left to the unqualified or inattentive.
Poor Planning
Poor planning and oversight can result in the grounding of your aircraft, or worse.
The Wrong Way
The wrong vendors and biased or weak contract negotiation can mean over paying and under delivery.
Poorly Maintained
A poorly maintained aircraft will cost you more to own and prove far more difficult to sell.
Technical Consultancy Without Compromise
Comprehensive maintenance oversight.
ACASS consults with you to determine your optimal safety needs. We handle warranty programs and subscriptions; scheduled/unscheduled maintenance and supervision; corrective action for defects and component replacement; management and archiving of technical records; and more.
The most qualified vendors.
Because ACASS is not owned by or beholden to any maintenance service provider, we are free to impartially source and negotiate with the best and most cost-effective vendors for all your maintenance-related services. We also provide invoice auditing and reconciliation.
The highest safety standards.
When it comes to aircraft safety, sufficient is insufficient. ACASS does not limit our commitment to safety to externally-mandated minimums. We always employ the most trusted safety protocols and certifications to manage risk, ensure compliance, and assure your confidence.

Frequently Asked Questions:
-
Aircraft technical consultancy covers the full range of advisory and oversight services tied to the technical condition, airworthiness, and maintenance of a business aircraft. Typical services include pre-purchase inspections, maintenance program management, MRO vendor sourcing and oversight, technical records management, invoice auditing, and airworthiness directive compliance monitoring. ACASS delivers aircraft technical consultancy as an independent consultancy, not as an MRO or maintenance vendor, so the advice you receive at every stage is impartial and aligned with the owner’s interests rather than a vendor’s workload. Connect with a Specialist.
-
Engaging aircraft technical consultancy support is most valuable at four common triggers: pre-purchase transactions, where a consultant evaluates the aircraft before you buy it; maintenance events, where oversight of MRO work protects owner interests; aircraft transitions or lease returns, where records and condition must be verified; and ongoing advisory support for owners without in-house technical expertise. Cross-border transactions and international operations particularly benefit from local regulatory knowledge and established MRO relationships that a consultant brings. Connect with a Specialist.

The demand for highly proficient business aviation professionals is growing rapidly in China. This market requires expertise and experience with local civil aviation authorities, as well as deep cultural awareness and sensitivity. ACASS excels in all of these areas.
