Engines and Engine-powered Equipment with Residual Fuel

Carry On Bags: No
Checked Bags: No

Though allowed in checked baggage by international regulations, engines using fuels, internal combustion engines, or fuel cell engines are not allowed in baggage in the United States.

Engines and engine-powered equipment that are totally purged of fuel and vapors may be carried as checked baggage (see separate entry).

For battery powered equipment, see separate entry.

 The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.
