The Mechanic's Creed was originally written by Jerome Lederer in 1941. The creed appeared on the back cover of the first issues of the Flight Safety Foundation's Aviation Mechanics Bulletin in 1953 and proved to be extremely popular. Mechanics around the world, "from Tokyo to Frankfurt, from Canada to Puerto Rico," wrote to request copies to hang in their offices and shops.
Upon my honor I swear that I shall hold in sacred trust the rights and privileges conferred upon me as a certified mechanic. Knowing full well that the safety and lives of others are dependent upon my skill and judgment, I shall never knowingly subject others to risks which I would not be willing to assume for myself, or for those dear to me.
In discharging this trust, I pledge myself never to undertake work or approve work which I feel to be beyond the limits of my knowledge; nor shall I allow any non-certificated superior to persuade me to approve aircraft or equipment as airworthy against my better judgment; nor shall I permit my judgment to be influenced by money or other personal gain; nor shall I pass as airworthy aircraft of equipment about which I am in doubt, either as a result of direct inspection or uncertainty regarding the ability of others who have worked on it to accomplish their work satisfactorily.
I realize the grave responsibility which is mine as a certified airman, to exercise my judgment on the airworthiness of aircraft and equipment. I, therefore, pledge unyielding adherence to these precepts for the advancement of aviation and for the dignity of my vocation.
A copy of this creed suitable for framing will be sent to any mechanic who sends his name and address to Flight Safety Foundation, Inc., 471 Park Avenue, New York 22, New York.
