Company
Independent Aviation MRO at Pinal Airpark, Arizona
SJH Aerocare was founded on a single principle: that world-class maintenance capability should not be exclusive to the largest MRO networks. We bring enterprise-grade precision to mid-tier operators and lessors from our home at Pinal Airpark.
Our Mission
Trusted MRO, Built for the Modern Fleet Operator
Seth Jim Humes Aerocare was established to fill a specific gap in the MRO market: the need for a mid-sized, technically rigorous maintenance provider that treats every aircraft with the same care as a fleet of thousands.
Operating from Pinal Airpark's uniquely favorable environment, we offer capabilities typically reserved for Tier-1 MROs — at a scale that allows us to offer personalized operator attention, faster decision-making, and genuine accountability at every level of the organization.
Our client base includes passenger and cargo carriers, aircraft lessors, private equity-backed fleet managers, and government contractors. Each client receives direct access to our technical leadership and a dedicated account point of contact throughout every maintenance event.

Core Values
The Standards We Operate By
These principles are not aspirational statements. They are the operational criteria against which every decision at SJH Aerocare is evaluated.
Regulatory Integrity
Every workorder is executed in strict conformity with FAA regulations, manufacturer maintenance manuals, and our approved Repair Station Manual. No exceptions, no shortcuts.
Technical Precision
Aviation maintenance tolerates zero ambiguity. Our team applies engineering rigor to every task — from a routine inspection to a full structural overhaul — because aircraft demand exactness.
Operator Partnership
We work as an extension of your operation. Transparent communication, proactive squawk reporting, and on-time delivery are foundational to every client relationship we build.
Continuous Improvement
We invest in tooling, training, and process refinement year over year. Our quality management system drives measurable improvement in defect rates, labor efficiency, and turn-time.
