After finding a broken elevator control cable following an aborted takeoff, what must be done according to NTSB 830?

The requirement to notify the nearest NTSB office immediately after discovering a broken elevator control cable following an aborted takeoff aligns with the National Transportation Safety Board (NTSB) regulations, specifically NTSB 830. This regulation emphasizes the importance of reporting accidents and incidents that involve significant operational failures, as they could pose a safety threat to the operation of the aircraft and to the public.

By notifying the NTSB, you initiate a process that allows for proper investigation and analysis of the incident, which is crucial for improving aviation safety. Such reports can lead to the identification of systemic issues, the development of best practices, and the implementation of new safety regulations to prevent similar occurrences in the future.

The other options do not meet the immediate requirements set forth by NTSB regulations in this scenario. Documentation for aircraft records and filing a maintenance report, while important, do not satisfy the urgent obligation to report significant malfunctions or potential hazards. Additionally, grounding the aircraft alone does not alleviate the need for proper reporting to the NTSB to facilitate thorough investigation and response to the incident.
