ABSTRACT
This chapter describes examples of lack of assertiveness, poor teamwork, and lack of integrity in the aviation maintenance environment. It discusses the use of pre- and post-task analysis scorecards to track individual as well as organizational progress in improving safety practices. The chapter explains the difference between rule-based safety and risk-based safety. It also describes the application of the Hawkins-Ashby model to practice risk-based safety. The chapter also discusses three key issues in post-task analysis: assertiveness, teamwork, and integrity. Raising the overall awareness regarding the importance of assertiveness is certainly important, but too often it tends to be limited to speaking-up. When a person with high integrity signs-off a maintenance task as complete, it is indeed complete. Every time a mechanic or a AME signs-off the airworthiness release of an aircraft, engineer is attesting, to the best of his knowledge and abilities, to the mechanical integrity and legal compliance of that aircraft.
