Aircraft maintenance includes all the tasks needed to ensure an aircraft’s continuing airworthiness. Accidents that result from these maintenance activities can be used to assess safety. This research seeks to undertake a preliminary investigation of accidents that have maintenance contributions. An exploratory design was utilized, which commenced with a content analysis of the accidents with maintenance contributions (n = 35) in the official ICAO accident data set (N = 1277), followed by a quantitative ex-post facto study. Results showed that maintenance contributions are involved in 2.8 ± 0.9% of ICAO official accidents. Maintenance accidents were also found to be more likely to have one or more fatalities (20%), compared to all ICAO official accidents (14.7%). The number of accidents with maintenance contributions per year was also found to have reduced over the period of the study; this rate was statistically significantly greater than for all accidents (5%/year, relative to 2%/year). Results showed that aircraft between 10 and 20 years old were most commonly involved in accidents with maintenance contributions, while aircraft older than 18 years were more likely to result in a hull loss, and aircraft older than 34 years were more likely to result in a fatality.
Ensuring aircraft are technically safe to operate is the realm of airworthiness, literally worthy of being in the air. This is achieved not only with technological tools and techniques, or with just personnel and manpower, it is guided and supervised by managers and leaders. As such, the objective of this paper is to understand the role leadership plays in maintaining aviation safety and aircraft airworthiness. To this end, a case study of the Hawker Sidley Nimrod XV230 accident that occurred on September 2, 2006 near Kandahar in Afghanistan, was utilized. The study concluded that leadership is a key aspect, specifically finding that leaders are responsible for articulating the organizations vision, strategic objective setting, and monitoring the achievement of those objectives. It was concluded that operational airworthiness is directly dependent on the leadership ability to provide direction, workplace culture, continued learning, and establish risk management systems for safe and airworthy operations.
The phenomenon of encountering instrument meteorological conditions (IMCs) while operating an aircraft under visual flight rules (VFRs) remains a primary area of concern. Studies have established that pilots operating under VFRs that continue to operate under IMCs remains a significant cause of accidents in general aviation (GA), resulting in hundreds of fatalities. This research used the Australian Transport Safety Bureau (ATSB) database, which contained a total of 196 VFR to IMC occurrences, from 2003 to 2019, with 26 having formal reports. An explanatory design was adopted, commencing with a qualitative study of the 26 occurrences with reports followed by a quantitative study of all 196 occurrences. Factors investigated included the locations and date of the occurrences, involved aircraft (manufacturer, model, type), pilot details (licenses, ratings, h, and medical), number of fatalities, and causal factors. Fisher’s exact tests were used to highlight significant relationships. Results showed occurrences were more likely to end fatally if (1) they involved private operations, (2) pilots only had a night VFR rating, (3) the pilot chose to push on into IMCs, (4) the pilot did not undertake proper preflight planning consulting aviation weather services, and (5) the pilot had more than 500 h of flight experience. Further results showed occurrences were less likely to end fatally if the meteorological condition was clouds without precipitation, if the pilot held a full instrument rating, or the pilot was assisted via radio. Analysis of the data using the Human Factors Analysis and Classification System (HFACS) framework revealed that errors and violations occur with slightly greater frequency for fatal occurrences than non-fatal occurrences. Quantitative analyses demonstrated that the number of VFR to IMC occurrences have not decreased even though initiatives have been implemented in an attempt to address the issue.
In aviation, procedural errors persist despite pilots having the correct knowledge and ability to perform particular flight tasks. These errors can be attributed to diagnostic errors, inaccurate situational assessment and poor hazard awareness. Eye tracking has emerged as a technology that can be used to monitor pilot performance and provide insights into attentional distribution and the underlying decisional processes. The study used a systematic literature review based on the Preferred Reporting Items for systematic reviews and Meta-Analyses (PRIMA) Statement. Relevant publications were searched from 25 databases. To search the databases, the study used the keywords "eye tracking", "eye tracking measurements", "eye tracking aviation safety" and "eye tracking pilot flight performance", as well as "eye tracking and pilot training" and "eye tracking and pilot assessment". From these databases, 48 publications were retrieved for analysis. Out of the 48, 33 were abstracts and 15 were full-texts. The 15 full-texts proceeded to systematic literature analysis. These studies were further divided to studies reporting the use of eye tracking as a training tool (7) and studies reporting the use of eye tracking as an assessment tool (8). The literature review demonstrates that eye tracking is a valid and effective tool that can provide quantitative data for flight performance and safety assessment. Continued growth in aircraft cockpit automation means that eye tracking remains an urgent and promising development in aviation research, especially in real-time eye tracking to predict and prevent pilot errors and in the integration of eye tracking technology in intelligent cockpit design.
