This paper gives an overview and summary of two projects conducted over the past two years. The first project hosted a Web-based Maintenance Resource Management (MRM) Seminar on the Safe Maintenance in Aviation Readiness and Training (SMART) Center for FLSW personnel in the Fall of 1999. The SMART Center utilizes the technical capabilities of the World Wide Web to provide resources and training for the continuing education of aviation maintenance personnel. The second project analyzed and tested the DoD sponsored Advanced Distributed Learning Sharable Content Object Reference Model (ADL SCORM) specification using the SMART Center as the basis for the analysis and testing of the specification. The Naval Postgraduate School in conjunction with the Naval Safety Center is currently conducting an evaluation of the new ADL SMART Center. The results of that evaluation will be presented during the World Aviation Congress conference.

The Maintenance Extension of the Human Factors Analysis and Classification System (HFACS-ME) was employed to categorize errors present in 470 FY 90-97 Naval Aviation Maintenance Related Mishaps (MRMs). HFACS-ME identified common error types present in MRMs: maintenance supervision, crew coordination, maintainer error, and procedural violations. The data derived from classifying maintenance errors was used to develop mathematical models that were then employed to generate notional cost estimates associated with them. These models were then used to forecast the potential impact of maintenance error interventions. Collectively, the taxonomic analysis and model development served to identify common maintenance error forms, and consequently the optimal targets that have the most potential return on investment (ROI).
