Mechanical Specialties Secures FAA STC for Revolutionary ADEC™ Dual Cargo Hook

A Breakthrough in External Load Safety and Capability

Developed over more than three years of rigorous engineering and certification, the patent-pending ADEC™ system represents a fundamental advancement in cargo hook design.

At its core, the ADEC™ Hook integrates:

• Two fully independent load systems within a single unit 
• Dual actuation capability for redundancy and control
• Seamless operation between HEC (Human External Cargo) and NHEC missions

Unlike conventional systems, no components are removed or reconfigured when transitioning between mission profiles. Both HEC and non-HEC loads are continuously supported by the system’s dual load beams, significantly reducing operational complexity and risk.

Designed for Mission-Critical Operations

The ADEC™ Hook is specifically engineered and approved for:

• Human External Cargo (HEC)
• High-value and precision lifting operations

This dual-redundant architecture enhances safety, flexibility, and mission readiness—delivering a capability previously unavailable in a single cargo hook solution.

Expanding Certification Across the Fleet

With this second STC approval, Mechanical Specialties is actively progressing additional certifications to extend ADEC™ technology across all major helicopter platforms worldwide, reinforcing its commitment to innovation and operator safety.
