2 ZRH Safety Newsletter Case studies In this section we look at concrete examples of safety incidents relating to our focus topic, investigating the background to them and highlighting the lessons to be learned. Incidents at Zurich Airport A Current case examples at Zurich Airport The following incidents could have been avoided with disciplined conduct: A1 Airbus A346 collides with a high loader An Airbus A346 arriving at stand E57 collided with an incorrectly parked high loader, which was standing by for handling. The ground crew noticed the incorrectly parked vehicle shortly before the collision. Unfortunately, it was no longer possible to correct the position of the high loader, and the engine of the Airbus A collided with the vehicle and was damaged. The passengers were able to disembark as usual via the passenger loading bridge. Considerable damage was caused to the aircraft. Conclusion Before the aircraft arrives at the stand, please ensure that no ground service equipment is within the aircraft stand area (within the red stand safety lines). A2 De-icing vehicle damages winglet during de-icing The left winglet of an Airbus A319 was damaged during de-icing in February. While manoeuvering, the driver of the vehicle concentrated on objects that were in the aircraft stand area. In doing so he failed to notice that he had touched the machine s winglet. A3 A truck and a limousine collide A truck travelling to an aircraft stand had to halt in order to allow an aircraft to pass. However, the truck only came to a stop in the danger zone, and the driver wanted to reverse a few metres. He failed to notice that a limousine had arrived behind the truck. While reversing, the truck collided with the limousine. Conclusion Keep an eye on the right-of-way for aircraft and make sure you can see them at all times. Pay special attention when reversing. If your field of vision is restricted, ask for assistance. Conclusion Keep aircraft stands free during de-icing. Caution is required when manoeuvering around the aircraft. 2

3 Safety basics is the section in each Safety Newsletter where we provide key information on the rules, regulations and procedures for the safety item we re focusing on. ZRH Safety Newsletter Safety Basics More discipline fewer accidents B Discipline In order to guarantee safety for flight operations at Zurich Airport, certain rules have to be respected by all drivers. Following the Ground Traffic Regulations (GTR) of Zurich Airport ensures that accidents and incidents in flight operations are avoided. All drivers at Zurich Airport are required to exercise the necessary discipline and to respect the GTR. B1 Incorrect conduct and deviation from procedures 1236 incidents were recorded in the Safety Office database between January and July They include incorrect conduct and deviations from procedures (including violations of the GTR). This constitutes the largest category in terms of all reported incidents. This category includes breaches of the GTR, vehicles that were incorrectly parked or which were blocking the taxiway and other deviations from the GTR. B2 What does discipline mean? Would you rate yourself as disciplined? How does one define discipline exactly? According to the dictionary, discipline means a system of rules for behaviour. The most important document here at Zurich Airport is the GTR. B3 The Ground Traffic Regulations The Ground Traffic Regulations (GTR) govern vehicle and pedestrian traffic in the non-public area of Zurich Airport. Drivers of vehicles must have a personal permit issued by Flughafen Zürich AG. Violations of the GTR are punished by means of a points system. The latest version of the GTR is available on the website of Flughafen Zürich AG: rampsafety C A selection of rules The following is a selection of articles from the GTR: C1 Principle Art. 12: Everyone is required to act in such a way so as not to hinder or endanger others during regular use of the traffic areas or to impact negatively on air traffic. C2 Right of way for aircraft Art. 30: Aircraft always have the right of way over all other traffic. This also applies to motor vehicles towing or guiding aircraft. 3

4 ZRH Safety Newsletter Safety Basics C3 Right of way for motor vehicles Art. 34: The right of way is regulated as follows in descending order: 1. Motor vehicles with illuminated blue danger lights and two-tone horn 2. Motor vehicles with illuminated yellow danger lights 3. Winter service vehicles during snow-clearing operations 4. Motor vehicles in traffic lanes C4 Reversing Art. 35 bis: Vehicles must always reverse at walking pace. Vehicles with no visual reversing aid and with limited visibility must be assisted when reversing. C5 Speed limit Art. 33 para. 1: Unless otherwise indicated, the maximum speed is 30 km/hr. D Safety Office tips Please observe the GTR rules. Act prudently. Adapt your driving to the circumstances (construction sites, traffic lanes, knowledge of the vehicle). Allow sufficient time. In-depth knowledge of the vehicle Learn from the mistakes of others so that the same errors are not repeated. Drive defensively. Driving defensively means: paying attention to traffic being in control of the vehicle at all times identifying dangerous situations at all times minimising the risk of collisions by braking C7 Driving onto aircraft stands Art. 20 para. 4: When the docking guidance system is activated, no traffic, pedestrians or objects are allowed onto the stands. The exceptions are tractors with towed aircraft and motor vehicles of Flughafen Zürich AG guiding an aircraft. 4

5 In this section we present the data that have been collected on accidents and incidents at Zurich Airport in graphic and diagram form. These visual interpretations should also help raise our readers awareness of the current hazards and risks. ZRH Safety Newsletter Statistics Incorrect conduct results in accidents Just the tip of the iceberg Very often one only sees the tip of the iceberg. The part below the surface is usually not adequately perceived. And yet this is what often causes accidents. As part of the Safety Management System, violations of the GTR are considered to be incorrect conduct or incidents with considerable potential for damage, depending on their seriousness. The adjacent statistics from 1 January 2012 until 31 July 2013 show that of the 693 cases of incorrect conduct, 352 were incidents with high potential for damage, 210 were incidents involving collisions with vehicles and buildings, and 65 involved damage to aircraft. In terms of incorrect conduct alone, the result is a ratio of 1:10. In other words, the less discipline, the more damage is caused to aircraft Damage to aircraft Stationary aircraft (e.g. passenger loading bridges) Aircraft loading equipment Aircraft servicing equipment Taxiing traffic (e.g. towing/push-back vehicles) Parked vehicles Collision between vehicles and buildings/vehicles Accidents involving vehicles Accidents involving equipment Accidents involving buildings Incidents with considerable potential for damage Foreign objects on taxiways and runways Near-collisions on traffic areas Incorrect conduct Incidents in flight operations Deviations from procedures during ground handling Damage to aircraft Collision with vehicles and buildings Incidents with considerable potential for damage Incorrect conduct People are often unaware of incorrect conduct Mistakes occur wherever people work. Employees who perform the same work over a lengthy period develop a routine over time. This can be a positive thing, as processes are automated and run almost by themselves. However, it can also happen that incorrect conduct occurs without an employee noticing. Disciplined conduct can help to avoid such situations and ultimately also accidents. 5

6 ZRH Safety Newsletter Expert perspectives In this section we present the views and experiences of various people at Zurich Airport on our focus topic. Driving at the airport requires more discipline The expert Jürg Hug Ramp Safety Flughafen Zürich AG Jürg Hug began his career in 1994 at Flughafen Direktion Zürich (later Unique AG and now Flughafen Zürich AG) in the bus service. In 2004 he moved to Ramp Safety and is now, among other things, the process owner for driving instruction and driving permits. Before working at the airport in Zurich he worked as a driving instructor. Mr Hug, what do you understand by discipline in terms of driving and traffic? A lot (laughs). I understand it to mean observing the rules and being fair when driving. Without discipline, traffic wouldn t function and would become a free-for-all. Being considerate of others is also part of discipline. For me this is very important as without rules which are discipline in a broader sense safe driving is not possible. Drivers own interpretations of traffic-related conduct are useless. Discipline implies that everyone should act in the same way. Traffic rules serve to eliminate misunderstandings. Do you find driving on an airport site more demanding? Does it require more discipline than in regular traffic? Yes, it does require more discipline. On the airport site one has to make clearer and more independent decisions, because in public traffic everything is indicated and regulated. Roads are clearly marked by pavements, meadows, etc. At the airport there are fewer reference points such as those we are familiar with in regular traffic. Also, in regular traffic, one does not have to deal with taxiing aircraft. In what way are you confronted with discipline? I am confronted with it several times a day. I act in a disciplined manner in order to be a good role model. On the other hand, in the course of my work I am sometimes confronted with the undisciplined conduct of other drivers. Has discipline improved over the years? That is difficult to say. Because we carry out more checks and have more people in these roles we can see more deviations than we did some years ago. On the other hand, more violations were seen then as checks were shorter and less frequent. So it s difficult to generalise. How do you teach disciplined conduct during your driving lessons? I try to make the trainees aware of the risks and their consequences. Proportionately the damage to an aircraft is 100 times greater than with a regular vehicle. In addition, it is possible to promote safe conduct by passing on tips. 6

7 ZRH Safety Newsletter Expert perspectives Can disciplined conduct be learned? Certainly. One way to do this is by questioning one s own behaviour. For example: Did I assess this traffic situation correctly? Did I observe the rules? By constantly asking questions one can train oneself: Knowing oneself is good discipline. What tips would you give all drivers on the apron to avoid incidents and accidents? Observe correctly and drive defensively. Be aware of other drivers and always consider where the other driver is going. Think about where you can stop and wait in order to give someone else the right of way and to observe the rules. Learn the correct behaviour patterns and use them consistently and correctly. Defensive driving in particular helps to avoid dangerous situations. One danger is that drivers act with an exaggerated sense of routine and thus underestimate the situation. Is discipline lost as a result of routine? Yes. Routine gives rise to a lack of attention, and actions are no longer carried out consciously. In a way, respect is lost. One allows oneself to be distracted by things that are unimportant and thus enters into risks. Dangers are then underestimated or not even perceived. What types of violations occur most frequently? This is difficult to answer (thinks). Probably not observing the warning lights when pushing back. The drivers often say that they saw them too late or not at all. This proves that people make their decisions on the basis of visual perception. So looking ahead is very important. What does the airport expect of drivers? Disciplined, correct and error-free driving and also consideration for one s partners. 7

8 ZRH Safety Newsletter Reporting system Reporting system What contribution can I make? Safety enhancement information helps to improve safety at the airport and is a clear sign of a positive safety culture. It is thus all the more important that employees report apparent or probable unsafe circumstances. The following are examples of safety enhancement information and safety measures. These examples illustrate the seriousness of clarifying safety enhancement information and are intended to motivate employees to report information aimed at increasing safety to the Safety Office. Information markings on taxiway YANKEE Pilots report to Apron Control that the information markings on taxiway YANKEE are missing. Apron Control realises that some crews did not notice the taxiway YANKEE and continue taxiing on the taxiway ALPHA. The Safety Office looks into the matter and observes the situation on the apron. It turns out that the renewal of the markings had been planned and communicated but that the information had not reached the apron traffic manager on duty. Winter OPS During the winter, the Safety Office repeatedly receives safety enhancement information about conduct on the ramp during winter service operations (e.g. snow-clearing), especially with regard to speeds that are not adapted, failure to give the right of way to snow-clearing and de-icing vehicles and passing in front of winter service equipment. To date, no serious accidents have occurred, as the winter service vehicles managed to brake or avoid other vehicles. Conclusion Be aware that accidents involving winter service vehicles could result in considerable damage to both people and property. Therefore please make sure you act in a disciplined manner during winter service operations in particular. 8

10 ZRH Safety Newsletter Accidents and incidents/ Upcoming safety dates The ZRH Safety Newsletter is intended to sensitize readers to the potential dangers inherent in all operations at Zurich Airport. To this end, every issue includes a section reporting on recent occurrences at Zurich and worldwide. Not all these occurrences are necessarily related to the current focus issue. Occurrences at international airports A Boeing B772 landed too early, broke up and went up in flames. An Asiana Airlines Boeing B en route from Seoul, South Korea, to San Francisco with 307 passengers on board landed too soon on runway 28L. The tail fin, the chassis and the engines were separated from the aircraft. The aircraft rotated almost 360 degrees before coming to a standstill around 460 metres from the runway and burst into flames. Three passengers died, while the remaining 304 were able to leave the aircraft with either slight or medium injuries. The American aviation accident investigation authority NTSB initiated an investigation. You can find information about international incidents and accidents at: reports.html Unmanned towing vehicle collides with Boeing B733 A Southwest Airlines Boeing B733 was struck by a tug while pushing back in Los Angeles, USA. The driver left his seat with the engine still running and wanted to load two suitcases. He lifted the first suitcase onto the passenger seat in the driver s cabin. When he turned round to load the second suitcase, the vehicle moved on its own until it collided with the Boeing B733. The driver was unable to jump onto the vehicle. That same evening the operating company announced that the first suitcase had fallen from the seat onto the accelerator and had set the vehicle in motion. The NTSB report stated that the seat switch, which turns off the engine if the driver s seat is empty, was not working. The aircraft sustained damage to the fuselage and the right engine. The passengers were flown to Tucson, Arizona, in a replacement aircraft and with a delay of two hours.
