The FAA said it is investigating whether Boeing completed the inspections to confirm adequate bonding and grounding where the wings join the fuselage on certain 787 Dreamliner airplanes "and ...
Electrical bonding is the practice of intentionally electrically connecting all exposed metal items not designed to carry electricity in a room or building as protection from electric shock. Bonding is also used to minimize electrical arcing between metal surfaces with electrical potential differences. If a failure of electrical insulation ...
MIL-STD-704 Aircraft Electrical Power Characteristics is a United States Military Standard that defines a standardized power interface between a military aircraft and its equipment and carriage stores, covering such topics as voltage, frequency, phase, power factor, ripple, maximum current, electrical noise and abnormal conditions (overvoltage and undervoltage), for both AC and DC systems.
In August 2020, the FAA published requirements for fixing each aircraft and improving pilot training. On November 18, 2020, the FAA ended the 20-month grounding, the longest ever of a U.S. airliner. The accidents and grounding cost Boeing an estimated $20 billion in fines, compensation, and legal fees, with indirect losses of more than $60 ...
ARP4754, Aerospace Recommended Practice (ARP) ARP4754B (Guidelines for Development of Civil Aircraft and Systems), is a guideline from SAE International, dealing with the development processes which support certification of Aircraft systems, addressing "the complete aircraft development cycle, from systems requirements through systems verification."
Electrical installations. An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipments conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.
2013 Boeing 787 Dreamliner grounding. In 2013, the second year of service for the Boeing 787 Dreamliner, a widebody jet airliner, several of the aircraft suffered from electrical system problems stemming from its lithium-ion batteries. Incidents included two electrical fires, one aboard an All Nippon Airways 787 and another on a Japan Airlines ...
