| Procedural errors were identified as the major cause of aircraft maintenance incidents (Veinott & Kanki, 1995). They examined 83 ASRS reports and found that these errors accounted for approximately 60% of all error types. In this paper, we examined more recent ASRS reports, those after 1996, for procedural errors, and analyzed them according to recently developed error analysis tools such as FRANCIE and MEDA. We evaluated reports on four levels: error type, written support information (document type, aspect of the document), verbal support information (communication type, aspect of the communication), and contributing factors (written, verbal). Awareness and task execution errors were the most frequent error type. Document type errors included maintenance manual and aspect of the document included completeness as the most frequent. The majority of communication type errors were between superior and subordinate and aspect of the communication involved problem solving/decision making. Written contributing factors had two errors in the majority: part design/tools/equipment and task related and verbal contributing factors had one, organizational culture. |
