Technical Consultancy

Peak aircraft performance, reduced-stress ownership, and peace of mind—all at highly competitive prices.

Keep your aircraft airworthy and worth owning.

Ensure the airworthiness of your aircraft, meet international safety standards, and protect the value of your asset through regularly scheduled and unscheduled maintenance programs.

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 and oversight can result in the grounding of your aircraft, or worse.

The wrong vendors and biased or weak contract negotiation can mean over paying and under delivery.

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 handles warranty programs and subscriptions; scheduled and unscheduled maintenance management and supervision; corrective action for defects and required component replacement; management and archiving of all 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 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 base our commitment to safety on externally-mandated minimums. We always employ the most trusted safety protocols and certifications to manage risk, ensure compliance, and assure your confidence.

Noteworthy Distinctions

IS-BAO Stage 3 registered SMS implementation experts.


Beneficial service center/aviation authority relationships.

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.
