HIRF & Lightning Certification by an FAA DER
HIRF and lightning compliance from planning through test, approved by a consultant DER.
Aries Aero Systems provides FAA DER support for High Intensity Radiated Fields (HIRF) and lightning protection. We cover system and equipment level compliance for avionics suppliers, STC holders and new aircraft programs.
HIRF and lightning are often scheduled late and found expensive. We define the environment, test levels and analysis approach at planning so qualification testing is done once.
What we cover
HIRF certification
HIRF environment definition, transfer function and test approach, and system-level compliance for Level A, B and C functions.
Lightning indirect effects
Transient level definition, equipment transient design levels and pin-injection / cable-bundle test planning.
Lightning direct effects
Zoning, direct attachment protection for structure, antennas, radomes and externally mounted equipment.
Fuel system lightning protection
Ignition source prevention considerations for fuel system installations.
DO-160 qualification
Test plans, lab witnessing and report review for Sections 20, 21, 22 and 23.
Regulatory basis we work to
- 14 CFR 25.1317 / 23.2520 (HIRF protection)
- 14 CFR 25.1316 (electrical and electronic system lightning protection)
- 14 CFR 25.581 and 25.954 (aircraft and fuel system lightning)
- AC 20-158A (HIRF), AC 20-136B (lightning indirect effects), AC 20-155A (lightning test)
- SAE ARP5412, ARP5413, ARP5414, ARP5416
- RTCA DO-160G Sections 20, 21, 22, 23
How an engagement runs
- 01Identify functions and their failure condition classifications.
- 02Agree the HIRF and lightning compliance approach and test levels with the authority.
- 03Review test plans, witness testing as needed and review reports.
- 04Compliance findings and 8110-3 approval within authority.
Frequently Asked Questions
When should HIRF and lightning be planned?
At certification planning. Test levels drive equipment design, shielding and wiring, so a late start usually means redesign or re-test.
Do you witness DO-160 testing?
Yes. We review test plans, witness testing at your chosen lab when required and review the reports for compliance.
