Get this from a library. Use of the square-root method to identify factors in the job performance of aircraft mechanics.

[Charles Wrigley]. Federal Aviation Administration. There are several evidences to prove the importance of management-related factors. In a study of the normal job performance of aircraft mechanics, McDonald et al.[7] found 34% mechanics admitted the performing of their recent task had contravened the formal procedures and organizational workflow to some by: 5.

Human Factors in Aviation Maintenance. The overall goal of Aviation Maintenance human factors research is to identify and optimize the factors that affect human performance in maintenance and. Performance Performance is a term used to describe the ability of an aircraft to accomplish certain things that make it useful for certain purposes.

For example, the ability of an aircraft to land and take off in a very short distance is an important factor for a pilot who operates in and out of short, unimproved airfields. The Operator’s Manual for Human Factors in Maintenance and Ground Operations 2 PRELUDE.

In the Federal Aviation Administration (FAA) worked with industry representatives to complete the Operator’s Manual for Human Factors in Aviation Maintenance (Op’s Manual). factors. Human factors directly cause or contribute to many aviation accidents.

It is universally agreed that 80 percent of maintenance errors involve human factors. If they are not detected, they can cause events, worker injuries, wasted time, and even accidents. [Figure ]. Board (NTSB) reports of major aircraft accidents. Written procedures refer to a variety of manufacturer publications, specific company job cards, or the rule in Code of Federal Regulations (CFR) 14 Part 43 Section (a) entitled, “Acceptable Methods, Techniques, and Practices – Aircraft Inspection and Repair.” The rule states that.

Even with all of this data, it is difficult to fully identify and understand the contributing factors of a maintenance discrepancy.

For maintenance performance, human generated event reports are. DFA Complexity Factor – Definition Cummins Inc. metric for assessing complexity of a product design Two Factors Np – Number of parts Ni – Number of part-to-part interfaces – Multiply the two and take the square root of the total – This is known as the DFA Complexity Factor S Np x S Ni.

man Factors and how they apply to aviation maintenance. used properly, hu-man factors principles and methods can help aviation maintenance supervisors, engineers, technicians, and inspectors perform their jobs with more efficiently, more safely, and with less stress.

in this Guide, the terms “human factors. Human factors involves gathering information about human abilities, limitations, and other characteristics and applying it to tools, machines, systems, tasks, jobs, and environments to produce safe, comfortable, and effective human use.

In aviation, human factors is dedicated to better understanding how humans can most safely and efficiently be. HUMAN FACTORS TRAINING COURSE. Protecting worker health, comfort, and well-being also results in improved task performance and a reduction in errors and accidents.

These regional requests were consolidated by AFS, Oklahoma City, and data consisting of 1, records were forwarded to the researchers. These records consist of all rule violation cases against certificated aircraft mechanics who were working for either a 14CFR Part or Part certificate holder.

Four important human factors of the Pear Model (Refer to Figure 5 for graphical illustration) are: People who do the job, environment in which they work, actions they perform and resources necessary to complete the job.

People. Human factors program focus on people who perform the work and attend to physical, physiological, psychological and. Some aircraft and avionics equipment mechanics and technicians learn their trade at an Federal Aviation Administration (FAA)-approved aviation maintenance technician school.

Others are trained on the job or learn through training in the military. Aircraft mechanics and avionics technicians typically are certified by the FAA.

A program to reduce on-the-job accidents and injuries based on the MEDA results form and investigation methods. "Operator Experience With MEDA Implementation" includes examples of MEDA benefits realized by specific operators and maintenance providers. Human factors impact everything in aircraft maintenance; there is no aspect of the work which is not affected in some way by human behavior.

Maintaining mechanical machines is a distinctly human thing to do, so the conditions in which the human technician finds themselves in play very relevant to the task of safely working on aircraft. machine spindle and grinding wheel and the use of an electrolyte instead of a coolant.

The tool the grinding wheel is the (-) of the electrical source and the part being machined is the (+). The technique is applied in machining carbide tools and alloy tools, carbide steel.

The interviewer could be asking you this question for a number of reasons. Obviously, the salary is an important factor to your interest in this job, but it should not be the overriding reason for your interest.

A good answer to this question is, “The salary was very attractive, but the job itself is what was most attractive to me.”. Prof. Newman, Page 1 Aircraft Performance Prof. Dava Newman Sr. Lecturer Pete Young Introduction to Aerospace & Design 12 February The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life.

Aircraft Mechanics - An Important Role. When I became a mechanic back inwe were called aircraft mechanics. Now the term used in the U.S. is aircraft maintenance technicians (AMT). In Europe under EASA rules they are called aircraft engineers. What ever you call them, they are an important piece in the aviation safety puzzle.

HUMAN FACTORS INTRODUCTION Aviation maintenance has changed over the years.1 Newer aircraft contain materials, power plants, and electronic subsystems that did not exist in earlier models, and the number of older aircraft has increased.

Technicians use more and more sophisticated equipment and procedures. aircraft mechanic interview questions. Learn about interview questions and interview process for companies. Best Cities for I would work any amount of overtime that is needed, as well as, complete the job with efficiency and safety.

Aircraft Mechanic at American Airlines was asked Mar 6, If I would be willing to relocate. Aircraft mechanics perform inspections, make repairs and perform scheduled maintenance of aircraft.

They have the ability to diagnose both electrical and mechanical problems and identify repair procedures. They are able to examine parts for defects and replace them with new ones.

Focusing on the qualities that are important for aircraft mechanics is one part that. In Europe, human factors training in the maintenance sector was mandated with a proposed change to JAR [EASA predecessor] in The move aimed to ensure human factor principles were adhered to when writing and establishing procedures relevant to aircraft maintenance personnel.

Traditionally, Human Factors endeavours have been directed towards flight crew performance and, to a lesser extent, towards the performance of air traffic controllers.

Until recently, available literature showed little consideration of the Human Factors issues which could affect aircraft maintenance personnel who inspect and repair aircraft.

Training new and existing employees can be a company’s biggest challenge, especially in a rapidly changing business environment. When I was chief human resources officer at Mirage and Wynn. The method 1. Identify function, constraints, objective and free variables List simple constraints for screening 2.

Write down equation for objective -- the “performance equation” If objective involves a free variable (other than the material): Identify the constraint that limits it Use this to eliminate the free variable in performance.

based on a systems approach. It incorporates a variety of human factors methods, such as job and work design, and considers the overall socio-technical maintenance system (see Chapters 2 & 6).2,9 For example, the SHELL model, Figureshows how we define human factors as.

The Beginner’s Guide to Fleet Management Page 3 Analyzing recorded data, extrapolating issues from the data, and recommending solutions. Example: Fleet managers should be able to view common routes that their vehicles take and identify alternate routes or.

aircraft maintenance will ensure not only continuing performance enhancement of the technician workforce, but also continuing flight safety. This strategic program plan details how the Aircraft Maintenance Division of Flight Standards Service (AFS) is responding to safety and human performance challenges via the Human Factors in Aviation.

Let’s consider some of the areas where mechanics can specialize and the job titles they get: Aviation Maintenance Technical Engineer (AMTE) An aviation maintenance technical engineer is someone who has focused his or her studies on the interrelated parts of an aircraft and how performance issues in one area can impact others.

Human factors issues, specifically human errors, contribute to more aircraft incidents and accidents than any other single factor. Human errors include errors by the flight crew, maintenance personnel, air traffic controllers, and others who have a direct impact on flight safety.

Flight mechanics, as an example of one of the disciplines, focuses on aircraft geometry and uses this to determine flight performance and flight characteristics. In aircraft design various approaches are adopted: • Statistics and experience are applied. • The design of aircraft takes place in a large number of iterations.Aircraft being added to the growing air carrier fleet have high technology flight decks, use advanced types of control systems, and incorporate a variety of new structural materials.

Sophisticated technology is the order of the day for the air carrier fleet of the 's. And yet, at the same time, we still must face the aging aircraft issue.
