What to do
Owners and operators of Boeing 787-8 and 787-9 airplanes equipped with P500, P600, P700, and P800 power panels should follow the Boeing Alert Service Bulletins to install protection covers on lug terminal tracks as soon as possible. Although not mandatory, the FAA recommends incorporating these safety measures at the earliest opportunity to reduce electrical shock risk.
Summary
The FAA Special Airworthiness Information Bulletin SAIB: NM-20-06 addresses electrical power system safety concerns on Boeing 787-8 and 787-9 airplanes. It highlights issues with inadequate protection covers on lug terminal tracks of P700 and P800 power panels, which may expose personnel to electrical shock risks. The bulletin provides information on affected power panels including P500, P600, P700, and P800 models installed on these aircraft.
What changed
This bulletin introduces awareness of exposed terminal lug openings and uninsulated terminal lug assemblies on certain power panels of Boeing 787-8 and 787-9 airplanes. It references Boeing Alert Service Bulletins that provide instructions for installing protective covers to mitigate electrical shock hazards. The bulletin does not mandate regulatory action but recommends voluntary compliance.
Why it matters
This information is important for aviation professionals involved in maintenance, manufacturing, and troubleshooting of Boeing 787 electrical systems to prevent minor electrical shocks. Operators and MROs need to be aware of potential safety risks to personnel working around power panels. Addressing these issues helps maintain safe working environments and supports continued airworthiness without requiring an airworthiness directive.
