Can a Director of Maintenance (“DOM”) rely upon work performed by other mechanics when he or she signs an aircraft’s logbook and returns it to service? Or, put another way, if a DOM returns an aircraft to service solely based upon representations by another mechanic that the work was, in fact, performed, is the DOM free from risk of enforcement action if the work wasn’t actually performed? For an explanation of why the answer to these questions is “no”, please read my article discussing the issue: A DOM’s Reliance Upon Work Performed By Other Mechanics Results In Revocation Of His Certificate And Ratings.
