What happens if an ACM does not meet ATP requirements?

When an Aviation Crew Member (ACM) does not meet the requirements set for the Aviation Training Program (ATP), it is crucial to ensure the safety and efficacy of operations. The correct course of action in this situation is for the commander to suspend the individual's duties and initiate an investigation. This response is essential as it allows for a thorough examination of the individual's qualifications, qualifications, and any underlying issues that may have contributed to the failure to meet ATP standards.

This process ensures accountability and maintains the integrity of the operation. It also serves as a necessary step to protect both the individual and the crew by addressing any deficiencies or areas needing improvement before the ACM can continue in their role safely. Taking immediate action through suspension and investigation emphasizes the importance of adherence to ATP standards in aviation, where safety is paramount.

The other options do not provide a suitable response to the situation, as reassignment or retraining does not address the immediate safety concerns, nor does simply filing a report without follow-up action.
