You can take petrol powered tools as checked-in luggage, under certain restrictions. These tools cannot be taken in your carry-on bag.
Combustion engines can contain liquids that are highly volatile and can have low combustion thresholds. These can’t be taken onto planes because there is a risk of them exploding or catching fire harming people and property. It is not safe to take them on the plane unless you have followed the restrictions and asked your airline in advance of your travel.
You will be asked to relinquish all dangerous or prohibited items found in your carry-on luggage. If you refuse:
AvSec x-ray bags going onto aircraft to ensure there is nothing dangerous in them. If something comes up on the x-ray that needs checking, the bag will be opened, searched and any dangerous good or prohibited item will be removed, with a bag search notification form left within the bag.
