(1) In this regulation:
"regular provider" , for stores of a particular kind, means a person that has established an arrangement, recorded in writing, with an aircraft operator for the supply of stores of that kind.
(2) An item of stores that is provided by a regular provider of items of that kind may enter a cleared area, a cleared zone or a cleared aircraft otherwise than through a screening point.
(3) To avoid doubt, an item of stores that is not provided by a regular provider of similar items must be cleared before it is taken onto a cleared aircraft or into a landside security zone (other than a crowded landside zone).
(4) The operator of a screened air service must ensure that stores are not accessible to unauthorised persons:
(a) in the case of an item that is provided by a regular provider of similar items--from the time the item is accepted from the provider or the provider's agent by the operator; or
(b) in the case of any other item of stores--from the time it is cleared;
until the start of the screened air service for which it is taken on board the aircraft.
(5) For each item of stores loaded onto an aircraft that operates a screened air service, the aircraft operator must keep, until the end of the air service, a record of the provider of the item.
