Abstract
Purpose: The purpose of the current study was fourfold: to identify bird strike reporting trends at Part 139 airports in Indiana (2001-2014) for comparison to national data; to determine which quarter of the year yields the most bird strike data; to gain a clearer understanding of the relationship between altitude and bird strikes, and to develop information based upon the data analyzed that can be used for the safety management of birds including comparisons to national data. Design/methodology: The researchers in this study answered the research questions by reviewing, sorting, and analyzing existing data. The data collection took place from March 01 to May 02, 2016. Two data sets were utilized for data collection. The National Wildlife Strike Database (NWSD) and the FAA Air Traffic Activity System (ATADS).Findings: When compared to national data, Indiana Part 139 airports have seen a faster increase in bird strike reporting during 2012 and 2014. Aggregate data indicated June through September (Quarter 3) had a significantly higher frequency of bird strikes reported. When examining bird strikes and altitude of occurrences, the exponential equation explained 95 % of the variation in number of strikes by 1,000-foot intervals from 1000 to 10,000 feet. Not surprisingly, the risk of bird strikes appears to decrease as altitude increases.Originality/value: This study adds to the body of knowledge by addressing the lack of published bird strike report analyses at a regional level. It also connects data analyses to safety management system (SMS) concepts and Wildlife Hazards Management Programs (WHMP). The aviation community can use regional bird strike data and information to develop or enhance existing wildlife hazard management programs, increase pilot awareness, and offers airport managerial implications.
Highlights
The world learned, in the aftermath of the miraculous accident involving US Airways Flight 1549, that birds pose a serious hazard to aviation safety and cause significant economic losses to the aviation industry (Dolbeer, 2009; Hardt, Colyer, & Allen, 2009)
The information obtained from these analyses provided a benchmark for aviation stakeholders, especially Part 139 operators, to develop, implement, evaluate, and improve required Wildlife Hazards Management Programs (WHMP)
Bird activity may be increasing in Indiana and/or aviation professionals, who operate at these locations are becoming more proactive with bird strike reporting
Summary
The world learned, in the aftermath of the miraculous accident involving US Airways Flight 1549, that birds pose a serious hazard to aviation safety and cause significant economic losses to the aviation industry (Dolbeer, 2009; Hardt, Colyer, & Allen, 2009). In the United States, bird strikes have resulted in, on annual average, 119,645 hours of aircraft downtime and $193 million in monetary losses (Dolbeer, Wright, Weller, Anderson & Begier., 2015). Only about 2% of the reports provided information about the financial losses related to the bird strike. The trend in under or inaccurate reporting is primarily attributed to several factors, including physical, which means the bird strike was not noticed by the pilots, during or post flight. Another example of physical is when a carcass is found but impossible to relate to an aircraft. Several strategies undertaken by the Federal Aviation Administration (FAA), in partnership with other aviation stakeholders from 2009 to 2013 have enhanced the quantity and quality of reporting (Dolbeer, 2015)
