Use of safety belts and child restraint systems

This regulation governs safety belt and child restraint use on Part 135 flights (commuter and on-demand operations). Everyone must use a safety belt during taxi, takeoff, and landing, with limited exceptions for seaplane dock handlers.

For children under age two, parents have two options: hold the child on their lap without a restraint, or secure them in an approved child restraint system that occupies its own seat. If using a child restraint, it must have proper labeling (typically showing it's certified for aircraft use) and be forward-facing and properly installed.

Importantly, the regulation prohibits certain restraint types including booster seats, vest/harness systems, and lap-held restraints. However, certificate holders generally cannot refuse an approved child restraint system if parents provide one and purchase a seat for the child, though operators may choose the best location for it and can provide their own approved systems.
