The authors assessed the real threat to civil aircraft traffic in Poland resulting from bird strikes. It was found that in the period 2013–2018, the probability of such events increased by four times. Data for this work were downloaded from the ECCAIRS database maintained by the Civil Aviation Authority. Air traffic events have been collected for several years in this database. An assessment of the energy of bird collision with the aircraft, resulting from the bird’s mass and relative speed of movement, was also presented. Ways to minimise the risk of collision were described by introducing crew warning systems and means to scare off birds from the airport grounds. The method of testing the resistance of turbine engines to the foreign body’s absorption was also shown, as well as design methods for increasing the engine resistance to bird strikes.

“…A methodology was developed to determine the forecast for the following year and to set alert levels for representative types of events, adopting the criterion 2σ. In order to make data analysis more objective, coefficients were introduced relating the number of events to the number of registered aircraft (per 1,000 aircraft) [9][10][11]. It would be more accurate to link the number of incidents to flight time, but there is no relevant data.…”

Threats to Aviation Safety Caused by Defects in Aircraft Airframe Systems

Alongside the increase in air traffic and number of aircraft, the number of reported aviation events has also been increasing. We processed the data included in the European Coordination Centre for Aviation Incident reporting Systems (ECCAIRS), analyzing small and large aircraft reliability and the safety of their operations, covering events according to ICAO aviation occurrence categories. Airframe systems are the largest contributor to the total number of reported events which occurred in Polish registered aircraft in the years 2008–2020. A detailed study of airframe systems reliability was carried out in order to assess the real reason for the failures. Airframe systems faults were assigned to specific ATA chapters and then to each of their sections. The results of this analysis may support the decisions of supervisory authorities in the areas where security threats are most important. They can also help aircraft operators with identification of the airframe units which require special attention. Identification of significant parts due to the frequency of malfunctions of particular system components may support designers. In short, these results are valuable in terms of further developments in statistical tools facilitating New Product Introduction (NPI).

“…Scientists of the Institute of Aviation have done a laborious processing of the data contained in that database analyzing them based on various criteria: 2 aviation occurrence categories (as defined by ICAO), 3 ATA chapters, 4 phases of flight for different airports in Poland, etc. Separately under consideration were aircraft with an MTOM <5700 kg (mainly General Aviation also called as a small aircraft) 5,6,7 and for aircraft with MTOM >5700 kg (Commercial Aviation – large aircraft). It was found that the largest part of the events are those that relate to powerplant, airframe and its systems failures.…”

Along with the increase in air traffic, the number of reported aviation events also increases. The authors have performed processing of the data included in the European Coordination Centre for Aviation Incident Reporting Systems (ECCAIRS) analyzing large aircraft reliability and safety of their operations considering events according to ICAO aviation occurrence categories. The airframe systems are the biggest contributor to the total number of reported events which occurred on the Polish registered large aircraft in the years 2008–2018. Failures of these systems caused more than 23% of total reported aviation events. Based on the ECCAIRS data, determination of occurrence categories essential for aviation safety was performed with the assessment of their safety risk level. Also, detailed airframe systems' reliability study was carried out in order to assess the real reason of their failures. Airframe systems' faults were assigned to the specific ATA chapters and then to each of their sections. The most frequently occurring defects of each unit of the particular airframe system were identified. The results of this analysis may support the decisions of supervisory authorities in the areas where security threats are most important. They can also help aircraft operators with identification of the airframe units which require special attention, and as support in improvement of safety analysis. Identification of significant parts due to the frequency of malfunctions of the system components can be a support for designers who have the information needed to improve the design of specific airframe system.
