"Grounding" shall mean the withdrawal of one or more aircraft from the flight operations or the imposition of speed, passenger or load restrictions on such aircraft, by reason of the existence of or alleged or suspected existence of any defect, fault or condition in such aircraft or any part thereof sold, handled or distributed by the Insured or manufactured, assembled or processed by any other person or organization according to specifications, plans, suggestions, orders, or drawings of the Insured or with tools, machinery or other equipment furnished to such persons or organizations by the Insured, whether such aircraft so withdrawn are owned or operated by the same or different persons, organizations or corporations.

A grounding shall be deemed to commence on the date of an accident or occurrence which discloses such condition, or on the date an aircraft is first withdrawn from service on account of such condition, whichever occurs first.
