UPON MY HONOUR I swear that I shall hold in sacred trust the rights and privileges conferred upon me. By knowing well that the safety and the lives of others are dependent on my skills and judgements, I shall never knowingly subject others to risks which I would not be willing to assume for myself, or those dear to me.
IN DISCHARGING this trust, I pledge myself never to undertake work or approve of the work which I would feel to be beyond the limits of my knowledge nor shall I allow any non-certified superior to persuade me to approve the aircraft or equipment as airworthy or operational against my better judgement, nor shall I permit my judgement to be influenced by money or other personal gain, nor shall I pass as airworthy, aircraft or 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 rests upon me as a certified airman, to exercise my judgement on the airworthiness of an aircrafts and equipment. I, therefore, pledge unyielding adherence to these precepts for the advancement of aviation and for the dignity of my vocation.
