  • This Presentation emphasizes the number 1 national maintenance related error causal/contributing factor in aviation accidents, " Failure to Follow Procedures”. This presentation is directed toward all maintenance personnel ( Certificated and Non -Certificated). This Presentation will cover: failure to follow procedures; causal factors; maintenance errors and introduction to
  • Review bullets and let them know what will be expected in this block. FAASTeam introduction registration Regulation Overview Accident Scenario Maintenance Error Findings Chain of Events Safety Nets Safety Motivation Safety Tools
  • The objective of this presentation is to provide a basic awareness of risk factors associated with failing to follow procedures. Additionally we will discuss prevention of contributing or causal factors so as to reduce maintenance errors as well ultimately reducing aviation accidents and incidents.
  • On behalf of the FAASTeam we hope you will take the opportunity to register at FAASAFETY.GOV and take advantage of the resources available to you.
  • Human beings have mental or cognitive limits. Many tasks can push those limits. As an example, your task here is to remove these nuts from the bolt. Now reassemble them back into alphabetical order. There is only one way to disassemble the nuts, but over 40,000 wrong ways to reassemble them.
  • Lets Get Started- But before we do!
  • Self Explanatory
  • Whether you are a certificated mechanic or not you still have to perform to the same standards. You MUST have CURRENT technical data, and tools and equipment as specified by the manufacturer. If the manufacturer states in the maintenance manual that you need a tool P/N 746385 you must have it to perform that task.
  • You must perform your work to the same industry and FAA standards as the next person. FAR 43.13(b) states that “Each person maintaining an aircraft shall do that work in such a manner and use the materials of such a quality, that the condition of the aircraft, airframe, aircraft engine, propeller, or appliance worked on will be at least equal to it’s original or properly altered condition (with regard to aerodynamic function, structural strength, resistance to vibration and deterioration, and other qualities affecting airworthiness).”
  • This means that all persons complying with FAR Part 43 must also comply with the operator’s operating manual or procedures outlined in the operations specifications. FAR.43.13(c) A Part 121, 127, 129, or 135 Air Carriers operating manual and operation specifications are considered an acceptable means of complying with this section.
  • Here we see the regulation that specifies the “Additional” performance rules for “INSPECTIONS”. This rule requires you use a checklist for the type of inspections being performed. Not only should you use the checklist but be very thorough as well. Go beyond the item your inspecting and use every tactic and tool to complete the evaluation.
  • The regulations require you to perform certain tasks in accordance with the manufacturer’s recommendation. Each manufacturer’s specifications vary and may further vary for that particular engine as per the serial number of the engine you are running. Ensure you have the documents for the job/task at hand. Verify you have and current revision as well as understand all the steps in the procedure you are about to do.
  • Read the question and answers. Ask for correct response. Answer: All the above Discuss further is necessary
  • You should be aware of these other sources of information which may affect the performance of your work or procedures you are following. All of these may contain information, whether mandatory or not, about the task you are doing on a particular aircraft. Our strong recommendation is to check them out before the task rather than after “approving for return to service”. Service bulletins Service instructions Airworthiness Directives Type Certificated Data Sheets Supplemental Type Certificates Instructions for Continued Airworthiness Advisory Circulars (AC43.13.1B) ect. Inspection procedures (Appendix D, Part 43) Air Carrier Procedures
  • Lets look at two specific Statistics. The first from the FAA regarding violations. Read and discuss Then look at what the NTSB investigations reveal. Note: The presenter may want to add additional comments on local statistics!
  • The slide content says it all!
  • Any of these factors add up to create an accident. Sometimes all it takes is one, but most frequently many factors will contribute to an error and several errors may be involved in the accident. Time permitting elaborate on any one of these factors.
  • If we look at aviation then and now, we can see that systems are much safer than they were for Orville & Wilbur Wright. As the reliability of the equipment has improved in the last century, the human element assumed a larger role in the causes of aviation accidents. Due to advancements made in technology and manufacturing the shift has been from mechanical failures to human errors.
  • So lets take a closer look at what we mean by human error. Human error involves usually unintentional acts (intentional acts are called sabotage - that’s completely different) some task or action is performed incorrectly. Usually, we are concerned about those that can degrade the system. Many errors may not result in any bad consequence. But they may increase the probability of a bad consequence. For example, you may drop a wrench and it hits the ground (no bad consequence), but there was a chance that it could have: - hit someone’s foot. What is this called? (on-the-job injury) - hit the plane. What is this called? (ground damage), or - been left in the aircraft only to jam up pulleys, control arms etc.
  • There are different types of human error. We may forget to do a task. Frequently this happens when we are interrupted or distracted by a new task or problem that comes up. We may do something incorrectly. For example hitting the up-button instead of the down-button. We may do something extra even when it is not called for this time.
  • Any of these errors can have different consequences, from no effect to a major catastrophic event. For example, rotating the propeller while working on the aircraft when the magneto is live could surely cause injury or even kill.
  • Failure to Follow procedures are results of human errors related to: Lack of Knowledge Lack of Current Technical Data Lack of Experience Lack of Proper tools and equipment Lack of Training Lack of Proper preparation Lack of Resources Failure to take Safety Precautions Failure to research FAR’s Discuss how each of these can effect the outcome of our assigned task
  • In every accident there are a series of events that link together to form a chain. We call this a chain of events. Discuss the four contributing factors in the chain. Note: There is a very good video that Boeing Aircraft produced that addresses this.
  • IF we can break the chain at any link, the accident doesn’t happen. Harry Truman had a sign on his desk that said “the buck stops here”. In maintenance we need the same philosophy. If we can break the chain at the maintenance level, the accident doesn’t happen.
  • Break the chain of events by complying with the performance standards set forth by regulatory, manufacturer’s and operator’s procedures.
  • Safety nets are mechanisms that you can put into place to help break the chain and insure an error doesn’t result in an accident. All of the factors that we talked about can be designed to prevent errors, just as they can help create errors if they aren’t conducive to human performance. What are some safety nets that you can put into place to prevent the errors we’ve talked about?
  • Safety Nets Perform task to best of your abilities Perform the task to be equal to it’s original condition Perform the task in accordance with appropriate data Perform the task using methods, techniques and practices acceptable to industry and the administrator Perform the task without pressures, stress and distractions
  • Re-inspect or have someone inspect your work before return to service Make the proper record entries for the work performed Perform the operational checks in accordance with the manufacturer’s or air carrier’s approved procedures
  • Motivation to follow procedures will be to: Do the job to the best of your ability Complywith the required regulations Be safety conscious Take pride in ownership Be a professional Its good for the company Its just good business
  • This is probably the least expensive but most useful tool you can use in your profession! It is the Personal Minimums Checklist. This is the “Before the Task” actions. Discuss the steps DON”T JUST KEEP THIS IN YOUR TOOLBOX!!...............USE IT!
  • This is “After the Task” actions. Discuss the steps Again………………….DON’T JUST KEEP IT IN YOUR TOOLBOX………………. USE IT!
  • This is an opportunity to evaluate the effectiveness of your training. You will be mentally challenged over the next several slides to correctly reassemble the nuts, by providing answers to specific questions. Each nut relates to the following topics we discussed in this presentation: regulatory overview, accident scenario, maintenance error, chain of events, safety nets, safety motivation and safety tools. Keep this bolt image in your mind as we proceed.
  • Nut A on the bolt represents the “ minimum standard of performance ” that maintenance personnel are responsible and accountable for when performing maintenance. ( 15 seconds to write your answer). The correct answer is FAR 43.13
  • Nut B on the bolt represents the functions or tasks that FAR 43.13 applies to. ( 15 seconds to write your answer) Answer: 43.13 (a), (b) and (c) speak directly to the performance of Maintenance, Alteration and Preventive Maintenance and the methods techniques and practices that must be used during any of the associated tasks.
  • (This is a two part question). Nut 3 on the bolt represents the minimum standard of performance that maintenance personnel are accountable for when performing what function or task. ( 15 seconds to write your answer) The correct answers are FAR 43.15 and Inspection
  • (This is a two part question) Nut D on the bolt represents the national statistics of aircraft accidents resulting from maintenance error. Maintenance caused accidents are increasing ? ( 20 seconds to write your answer)
  • This is a rhetorical question where the instructor simply reads the question and provides the answers. Nut E on the bolt represents “Chain of Events”
  • Ask the question to stimulate answer and discussion. Slides 28-29 for all the Safety Nets Nut F on the bolt represents eight safety nets that can be employed to prevent a failure to follow procedures including employing the mechanisms of performance rules to break the chain of events
  • Nut F on the bolt represents at least eight practices and or traits of motivations for reducing failure to follow procedure maintenance errors. Name at least three that we have discussed today. (30 seconds to write your answer)
  • Nut H on the bolt represents a safety tool designed to prevent failure to follow procedure events. Name that tool. ( 15 seconds to write your answer). The Personal Minimums Checklist outlines steps to use before and after a maintenance or inspection task that will, if it is used, reduce maintenance errors.
  • Congratulations on your successful and correct reassembly of the nuts on the bolt. You are on a path to preventing a failure to follow procedures!
  • Review the summary. The FAA Safety Team (FAASTeam) is available for information and your training needs. Please take the opportunity to register at Familiarize yourself with the regulations and understand your performance standards associated to them. Break the chain of events when you see or know something is not correct. Establish Safety nets to assure the same errors do not happen again. Realize the safety motivation is be a part of the “Safety Culture” to prevent accidents. Use the safety tools as memory joggers to prevent failure to follow procedures.
