Philips FRx Aviation Battery (TSO C-142)

TSO-C142 is the FAA Technical Standard Order that defines airworthiness requirements for AEDs and their batteries installed on commercial aircraft. The Philips FRx Aviation Battery carries TSO-C142 certification, making it the only Philips battery approved for in-flight use under 14 CFR 121.803. The standard verifies battery performance under flight conditions including pressure changes, vibration, and emergency-decompression scenarios. For airlines, TSO-C142 is mandatory; for ground-based facilities, it’s unnecessary and adds cost.

No — standard M5070A is NOT FAA-compliant for aviation installations. Using it in an aviation-configured FRx puts the airline out of compliance with 14 CFR 121.803 and creates legal exposure during FAA audits. For aviation use, only the TSO-C142 certified Aviation Battery is approved. The cost difference (~$295 vs $189) is small compared to the regulatory consequences of non-compliance. Airlines should procure exclusively through authorized aviation-medical-equipment distributors who confirm TSO certification on every battery shipment.
