Use of Resources

• 1). Gather all of the data for the specific aircraft being audited. Gather the make, model, and serial number of the aircraft, engine, and all installed avionics.
  
  
• 2). Review the aircraft maintenance log book for required inspections. Look specifically for the 100-hour inspection or progressive inspection if the aircraft is used for commercial purposes, and the annual inspection for all aircraft. Review the FAA regulations specific to the type of flight operation to determine the types of inspections and intervals.
  
  
• 3). Cross-check the aircraft's minimum equipment list with the equipment on the aircraft. Be sure that all equipment listed is properly installed and operable. If there are any discrepancies, look for any waivers or other approvals for operating the aircraft without a specific item.
  
  
• 4). Review all FAA Airworthiness Directives (ADs), which are mandatory maintenance items, issued for the aircraft. Inspect the maintenance procedures to ensure that each required directive has been complied with and annotated in the maintenance log.
  
  
• 5). Review Special Airworthiness Information Bulletins (SAIBs) published by the FAA for the specific aircraft to look for items that have been recommended for inspection, but not required.
  
  
• 6). Review maintenance alerts that the FAA receives from other aircraft owners and operators regarding the specific aircraft and all of its systems.
  
  
• 7). Review the workshop's maintenance internal procedures. The procedures should have a description describing the types of approved tools and parts they have in inventory to ensure they are in compliance with minimum FAA standards. Look for checks and balances the technicians use to avoid losing parts, overlooking steps in maintenance procedures, and providing other internal quality control measures.
