How Trust In Commercial Airline Pilots Is Affected By Their Perceived Sociability: A Mediation Analysis, Stephen Rice, Scott R. Winter, Russell Tokarski

Publications

Sociability relates to one’s preference to interact with others or remain alone. The current study sought to determine how a pilot’s perceived sociability would relate to consumers’ trust ratings in their pilot using participants from India and the United States. Consumers were presented with one of two scenarios. In the control condition, the pilot was described as sociable, while in the other, the pilot was presented as unsociable. Participants were then asked to rate their trust in the pilot based off of these cues. In general, participants indicated that the pilot who was perceived as unsociable was less trusting compared …

Causes And Trends In Maintenance-Related Accidents In Faa-Certified Single Engine Piston Aircraft, Douglas Boyd, Alan Stolzer

Publications

The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question.

The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR Part 91. Pearson Chi-Square, Fisher’s Exact Test, and Poisson probability were used in statistical analyses.

The rate of maintenance-related general aviation accidents was 4.3 per million flight hours for the 1989–1993 period and remained unchanged for the most recent period (2009–2013). Maintenance errors …

How Do Depression Medications Taken By Pilots Affect Passengers' Willingness To Fly? A Mediation Analysis, Stephen Rice, Scott R. Winter, Keegan Kraemer, Rian Mehta, Korhan Oyman

Publications

The mental health of airline pilots has been a concern for decades. In 2010, the United States Federal Aviation Administration began allowing four types of selective serotonin reuptake inhibitors (SSRIs) to be used by pilots suffering from depression. After a procedural wait period, pilots may be awarded a special issuance of their medical certificates to maintain flight currency. Missing from the literature was any research on consumer’s perceptions of pilots taking antidepressants, along with some other approved medications. Therefore, the purpose of the current study was to examine consumer’s willingness to fly once told that the pilot of their hypothetical …

Should Charity Air Medical Organizations Require Commercial Certification Of Their Pilots?, Douglas Boyd, Charles Peters

Publications

Fixed-wing medical transportation crashes operating under 14CFRPart 91 show higher fatal outcomes than non-medical Part 91 flights. Advanced certification may translate into increased safety; yet we know of no charity aeromedical transportation requiring such certification. Herein, in a retrospective study, we determined (a) whether commercial certification is associated with a reduced fatality rate compared with the less stringent private pilot certificate and (b) accident causes.

Causes And Risk Factors 1 For Fatal Accidents In Non-Commercial Twin Engine Piston General Aviation Aircraft, Douglas D. Boyd

Publications

Accidents in twin-engine aircraft carry a higher risk of fatality compared with single engine aircraft and constitute 9% of all general aviation accidents. The different flight profile (higher airspeed, service ceiling, increased fuel load, and aircraft yaw in engine failure) may make comparable studies on single-engine aircraft accident causes less relevant. The objective of this study was to identify the accident causes for non-commercial operations in twin engine aircraft. A NTSB accident database query for accidents in twin piston engine airplanes of 4-8 seat capacity with a maximum certified weight of 3000-8000lbs. operating under 14CFR Part 91 for the period …

Controlled Rest In Position (Crip): Consumer Perceptions In The United States, Scott R. Winter, Jason Carryl, Stephen Rice

Publications

Controlled rest in position (CRIP) has been suggested as a viable countermeasure to the Federal Aviation Administration (FAA) in the ongoing efforts to combat in-flight pilot fatigue. It is already in use in other parts of the world; however, it is not currently permitted in the United States. While expert opinion suggested it poses little threat to flight safety, with valuable returns in terms of improved crew alertness and performance, there is some doubt about the level of consumer buy-in. This study completed a preliminary investigation into overall consumer willingness to fly, in the use of CRIP procedures in the …

Boeing Workshop: Aircraft Construction And Familiarization, Rita "Rene" Herron, Jason Graber

Publications

In May, the ARFF WG, Boeing Fire Department (BFD), and Port of Seattle, Fire Department (Sea-Tac) offered an aircraft construction, familiarization and educational workshop. This three-day training event reached the full capacity of fifty attendees and focused upon the Pacific Northwest ARFF training and Boeing Aircraft production for the 737, 747, 777 and 787 aircraft. Attendees represented thirteen U.S. states and three foreign countries: Canada, Germany and Singapore.

Arff Wg's Response To The Ntsb's Recommendations, Rita "Rene" Herron

Publications

This piece is the final installment in a series of articles discussing research in connection to the four applied research projects the ARFF Working Group and Federal Aviation Administration are conducting concerning the National Transportation Safety Board’s recommendations from the report of findings on the crash of Asiana Flight 214.

A Trustworthiness Of Commercial Airline Pilots (T-Cap) Scale For American Consumers, Stephen C. Rice, Rian Mehta, Scott Winter, Korhan Oyman

Publications

The purpose of this study was to create a Trustworthiness of Commercial Airline Pilots (T-CAP) scale that could be used with American participants. Previous research (Rice, Mehta, Steelman, & Winter, 2014) created a similar scale that may be used with Indian participants. However, due to cultural differences, it was necessary to recreate an instrument that could be used with American consumers. In fact, the scale developed by American participants did differ significantly, both in terms of length and items to measure trustworthiness of commercial pilots. Participants were used in the entire process of creating the scale, including item generation and …

Marbles: The Application Of Input-Output Concepts To Safety Management Systems, Tim Brady, A. Stolzer, Anthony Brickhouse, Antonio Cortes, Dan Mccune, Jayathi Raghavan, David Freiwald

Publications

The goal of this research was to apply the economic concept titled Input-Output Analysis to an aviation safety concept titled Safety Management Systems (SMS). Input-Output (IO) is based upon the interrelationships of various components of an economic system and what happens to the system when one or more of those components changes. Since SMS is, by definition, a system with definable components, the research sought to determine if the interrelationships between those components could be determined and quantified. The term ‘‘marbles’’ was used to describe the activities that led to the IO-SMS matrix. Marbles was used as a metaphor for …
