Aircrew suspension is a temporary status used to protect flight safety while issues are reviewed and corrected. It typically arises from observable factors that can be remediated through training, discipline, or behavior changes. The kinds of issues that most commonly lead to suspension are lack of proficiency or poor judgment, which directly affect safe flight operations; violations of flying regulations, which indicate noncompliance with mandatory standards; and undesirable habits, traits, or characteristics that undermine reliability and safety. Medical disqualification, on the other hand, is usually handled through medical grounding and clearance processes rather than a standard suspension. It often leads to removal from flying duties on a medical basis rather than the typical remediation-driven suspension. For that reason, medical disqualification is not a common suspension trigger.
