What is the maximum duration a temporary correct can remain in the field without re-evaluation?

The correct maximum duration a temporary correct can remain in the field without re-evaluation is six months. This time frame is established to ensure that performance and capabilities are regularly assessed, maintaining high standards for safety and operational effectiveness.

Re-evaluating these temporary credentials after six months allows authorities to verify that the conditions under which the temporary credentials were granted still apply and that the personnel meet the necessary standards to continue operating safely and effectively. This periodic evaluation helps to mitigate risks associated with personnel who may have become less proficient or encountered situations that could affect their ability to perform their duties safely.

The other durations do not align with the regulatory structure in place for temporary credentials. A shorter duration, such as one month or three months, would not provide adequate time for personnel to carry out their duties meaningfully before requiring a review. Similarly, extending this period to twelve months would pose a risk by allowing personnel to operate without necessary oversight for an extended time, potentially compromising safety and operational integrity.
