  • Primary & Backup Quick-Release Systems (PQRS / BQRS)
  • Hoist provisions, swivels, shackles, & rigging hardware
  • 3D parametric CAD modeling, tolerance stack-ups, & CNC prototyping
CAP // 01.B TECHNICAL TEXTILES & RIGGING

HEC & NHEC SOFT GOODS DOCUMENTATION

Comprehensive product design and production-ready manufacturing drawing packages for certified airborne soft goods, synthetic rigging, and human restraint assemblies used in utility and rescue missions.

  • HEC full-body harnesses, crew restraints, & adjustable lanyards
  • High-modulus synthetic longlines, lifting slings, & protective jackets
  • Detailed stitch-pattern layouts, thread specs, & webbing terminations
  • Bill of Materials (BOM) structuring, labeling, & lot traceability
CAP // 01.C AUXILIARY & TERTIARY MODIFICATIONS

ROTORCRAFT ROLE EQUIPMENT & ASSEMBLIES

Industrial and mechanical product development for tertiary/auxiliary rotorcraft installations that expand pilot situational awareness, vertical-reference visibility, and multi-mission cabin utility.

  • External cargo mirror assemblies & aerodynamic fairing enclosures
  • Bubble observation window doors & vertical-reference provisions
  • Auxiliary utility mounts, brackets, & cabin/cockpit role equipment
  • Ergonomic field-of-view studies & airframe interface packaging
CAP // 01.D PROGRAM & CERTIFICATION MANAGEMENT

STC MANAGEMENT & DAR / DER COORDINATION

End-to-end project management guiding products from initial concept through Supplemental Type Certificate (STC) and PMA approval—coordinating directly with external regulatory delegates and airworthiness authorities.

  • STC project planning, schedule management, & certification data packages
  • External coordination with TCCA DARs, FAA DERs, & Approved DAOs
  • Direct liaison with TCCA, FAA, & EASA certification specialists
  • Test plan preparation, rig fixture design, & conformity inspection prep
02 // PRODUCT DESIGN

PRECISION DESIGN ACROSS HARD GOODS, SOFT GOODS, & ROLE EQUIPMENT.

Every component is developed for manufacturability, operator ergonomics, and seamless progression through external DAR/DER and authority review. Explore our three core product design pillars below.

HEC & NHEC HARD GOODS PRODUCT DEVELOPMENT

Specialized industrial and mechanical design for external load hardware—including cargo hooks, hoists, primary/backup quick-release mechanisms (PQRS/BQRS), and rigging interconnects. Designed for anti-fouling geometry, gloved-hand ergonomics, and straightforward field inspection.

HARDWARE SCOPE Cargo Hooks, Belly Mounts, Hoist Interfaces, Swivels, Quick-Release Mechanisms, & Shackles
MECHANISM DESIGN Primary & Backup Quick-Release (PQRS/BQRS) layouts — mechanical, electrical, & manual actuation
DOCUMENTATION ASME Y14.5 GD&T machining drawings, assembly procedures, & CMM inspection specifications
REGULATORY PATH Designed for FAR 27/29.865 & CAR 527/529.865 compliance with external DAR/DER substantiation
03 // STC PROCESS

DISCIPLINED PRODUCT DEVELOPMENT FROM CONCEPT TO STC APPROVAL.

We manage the complete design and certification workflow—delivering mature CAD, prototypes, and manufacturing packages while coordinating formal substantiation with accredited DARs, DERs, and regulatory authorities.

PHASE 01 GATE // CONCEPT & SCOPE

OPERATIONAL REQUIREMENTS & STC PLANNING

Definition of mission requirements, operator ergonomics, airframe interface geometry, and regulatory certification basis in alignment with project DARs/DERs and authority guidelines.

PHASE 02 GATE // DESIGN FREEZE

3D PRODUCT DESIGN & MANUFACTURING DRAWINGS

Detailed parametric CAD modeling, mechanism kinematics, soft-goods stitch layouts, tolerance stack-ups, Master Drawing Lists (MDL), and Design for Manufacturability & Assembly (DFM/DFA).

PHASE 03 GATE // PROTOTYPE & FIT

PROTOTYPING, FIT CHECKS, & TEST COORDINATION

Vendor management for CNC, sheet-metal, composite, and textile prototypes; aircraft fit-checks; test fixture design; and coordination of conformity and qualification testing.

PHASE 04 GATE // STC ISSUANCE

DAR / DER SIGN-OFF & AUTHORITY ACCEPTANCE

Compilation of Installation Instructions, ICA, and Flight Manual Supplements, working seamlessly with external DARs, DERs, DAOs, or directly with TCCA, FAA, and EASA specialists through final approval.
