Founder and Editor, AHLH. Heavy-lift planning and jobsite coordination.
Erran F. Yearty is the founder and editor of American Heavy Lift Helicopters. He is a co-founder of Fair Lifts Helicopter Services and served as its Chief Marketing Officer. He has helped plan heavy lift operations and worked on site, under the downwash, alongside ground rigging crews and rooftop setting crews. His experience comes from coordinating the work and being there as loads move from the ground to their set points.
At AHLH, he writes and edits for readers who need to understand how a lift is planned and what can change the estimate. He pays particular attention to the qualifications behind aircraft capacity figures and regulatory requirements, including exceptions that can change how a rule applies to a job.
He is also a software engineer and web developer, and the CEO of Sputnik Digital Effects. He has managed and developed the software and portfolio projects presented on its website. The software includes VanityFilter, Sputnik Markdown Viewer, AI Stripper and Sputnik Signal. His portfolio work includes the website and AI systems built for Clean Getaway, as well as VanityFilter and Fair Lifts.

The Case for Expert Lift Coordination: How Professional Planning De-Risks a Heavy Lift
Why professional lift coordination de-risks a heavy helicopter lift, from lift specification and operator vetting to aircraft matching and schedule staging.
Rigging a Helicopter Lift: Slings, Angles, and the Design Factors That Keep a Load Flying
Why aerial rigging departs from crane practice: center of gravity, sling-angle tension, 5:1/7:1/10:1 design factors, and ASME B30 hardware.
How to Vet a Helicopter Lift Operator: A Part 133 Prequalification Guide
A prequalification guide to verifying a helicopter lift operator's Part 133 certificate, insurance stack, and safety record before you sign.
High, Hot, and Heavy: How Density Altitude Governs Every Helicopter Lift
Helicopter payload is dynamic: it falls roughly 3% per 1,000 ft of density altitude, so high, hot sites cut capacity well below the brochure figure.
How Much Weight Can a Helicopter Lift? Capacity Tables from Light Twins to the Mi-26
US civil helicopters top out near 28,000 pounds on the hook; the Mi-26 lifts 44,000. The full capacity table, with the density altitude math behind every number.
