Shipping Aircraft Secondary Power Distribution & Solid-State Power Controllers from USA to UK, Germany & France: 2026 Avionics Guide

Shipping Aircraft Secondary Power Distribution & Solid-State Power Controllers from USA to UK, Germany & France: 2026 Avionics Guide

Modern commercial transport aircraft (Airbus A350, Boeing 787 Dreamliner, A320neo) utilize Secondary Power Distribution Assemblies (SPDA) equipped with microchip-controlled Solid-State Power Controllers (SSPC). Replacing traditional electro-mechanical thermal circuit breakers, these advanced avionics units distribute 28V DC and 115V AC electrical power to flight-critical avionics, flight control actuators, and environmental control systems.

Manufactured and overhauled by tier-1 aerospace electronics contractors in California, New York, and Florida, replacing failed SPDA modules for European airlines requires expedited transatlantic rotable logistics.

1. Regulatory Airworthiness: Dual-Release FAA Form 8130-3 & EASA Form 1

Every avionics SPDA module and SSPC card consigned to European maintenance repair and overhaul (MRO) centers must meet strict airworthiness traceability:

• Dual-Release Statement: FAA Form 8130-3 must contain specific block 12 text verifying compliance with EASA Part-145.
• Non-Incident Certification: Original certificate stating the avionics component has not been subjected to extreme electrical surge, fire, or aircraft crash conditions.
• Traceability Chain: Full OEM traceability back to the approved production certificate (PC) holder.

3. European Customs Protocols: Inward Processing & End-Use Relief

• United Kingdom (HMRC): Civil aircraft avionics clear customs under Autonomous Tariff Suspension or End-Use Relief using customs procedure code (CPC) 40 00 000, eliminating UK import customs duties.
• France & Germany (EU Customs): Classified under HS code 8537.10.91 (Electronic boards for voltage not exceeding 1,000 V for civil aircraft), exempt from customs tariff under the Agreement on Trade in Civil Aircraft (ATCA).
• AQX AOG Priority Desk: AQX arranges immediate LAX export departure to London Heathrow (LHR), Frankfurt (FRA), and Paris Charles de Gaulle (CDG) within 24 to 48 hours.
