Assessing Past Airworthiness Directives And How Safety Management Systems May Benefit Aviation Product Design And Manufacturing, Damon Lercel, Manoj Patankar, Richard Steckel

Journal of Aviation/Aerospace Education & Research

The European Union Aviation Safety Agency (EASA) continues to promulgate Safety Management Systems (SMS) across aviation organizations when it recently issued SMS requirements for EASA certificated Part 145 maintenance, repair and overhaul (MRO) organizations and Part 21 Design & Manufacturing (D&M) organizations. Currently, the Federal Aviation Administration (FAA) has no such rule in place for these U.S.-based organizations, which may challenge those doing business in countries where EASA policies apply. Given that a majority of the United States’ D&M and MRO population is made up of smaller organizations, it is likely a U.S. SMS regulation will require justification of the …

Under Pressure: Decision Making In Aircraft Maintenance And The Role Of Gender, Stephanie Douglas Ph.D., Bettina M. Mrusek Ph.D.

National Training Aircraft Symposium (NTAS)

In aircraft maintenance, leaders are under near-constant pressure to maintain airworthiness. Every minute an aircraft cannot fly due to maintenance represents financial waste. Decisions are therefore made in a relatively quick fashion. A leader evaluates the situation, identifies a course of action and then communicates this message to a team of technicians. However, gender influences regarding leaders’ decisions can influence team members’ perceptions of those decisions.

The study will measure decision making methods of leaders in aircraft maintenance and the perceptions of the technicians. It informs how gender influences decision making from both the leader and follower perspective. The expected …
