12/31/2010. France became the second European country to operate the ADs when the Armee de l'Air obtained 100 flyable AD-4 aircraft from the surplus USN stockpile in 1959 for use in the Algerian action. Some of these aircraft were "surplused" to the Cambodian AF beginning in 1965. The pictured aircraft was coded "20-QO" and assigned to EC2/20, conflicting sources state the aircraft was written off on either August 7, 1961, or April 4, 1963.
