2.13.2  Circuit Breaker Reset Philosophy

The aviation industry and regulators have taken steps to review and standardize their approach to resetting tripped CBs. Aircraft manufacturers have issued policy statements and the FAA has attempted to standardize the industry's approach. While these initiatives provide guidance and raise awareness in certain sectors of the aviation community about the consequences of inappropriate CB resets, the initiatives are limited in scope and are transitory in nature. The regulatory environment (regulations, advisory material, etc.) does not convey the reset philosophy currently accepted by the aviation industry or emphasize the consequences of inappropriate CB reset. Providing this information in documents such as Advisory Circular (AC) 43.13-1B would reflect the universality of the issue and enhance the probability that the most suitable approach to the resetting of tripped CBs is adopted in all sectors of the aviation industry.
