Procedures and Work Instructions

       A work instruction is what you should do, whereas a procedure is how you should do it.        Job cards are usually work instructions; procedures generally originate from the Maintenance Manual. 

      Writing Procedures and Work Instructions As well as maintenance data and procedures provided by the manufacturer having scope for improvement, there is also often a better way of writing or presenting technical procedures and work instructions which are produced by, and used within, a maintenance organisation.                                                                   Obviously the fundamental elements of the procedures should not deviate from the manufacturer’s requirement, but there is often scope for presenting that information in such a way that it is more easily understandable and usable. 

       Guidelines for Designing Procedures

  1. Procedure design and changes should involve maintenance personnel who have a good working knowledge of the tasks.
  2. All procedures, and changes to those procedures, should be verified and validated before use where practicable
  3. Ensure procedures are accurate, appropriate and usable, and reflect best practice
  4. Take account the level of expertise and experience of the user; where appropriate provide an abbreviated version of the procedure for use by experienced technicians
  5. Take account of the environment in which they are to be used
  6. Ensure that all key information is included without the procedure being unnecessarily complex
  7. Where appropriate, explain the reason for the procedure
  8. The order of tasks and steps should reflect best practice, with the procedure clearly stating where the order of steps is critical, and where the order is optional.
  9. Ensure consistency in the design of procedures and use of terminology, abbreviations, references, etc
  10. Provide training on the use of technology to access and print procedures and maintenance data.
  11. Ensure that printing and copy quality is good, and that there are enough printers, copiers, etc.

Human Factor Introduction

Human Factor -  A  Person working in a maintenance environment requires human factor knowledge as per his job requirement. Human Factor Training  - Aviation safety relies on maintenance. When it is not done correctly , it may cause an incident or an accident.  Mistakes of maintenance personnel is difficult to detect. They are subjected to work in changing working in variety of adverse conditon. Regulatory Requirement : CAR 66 Module 09 Human factor - for get AMEL Human Factor   - Study of human capabilities and limitations in the workplace.   It is about study of the interaction  of maintenance personnel, the equipment used, the written and verbal procedures and  rules followed by them, and the environmental conditions of any system.  Aim of human  factors is to optimise the relationship between maintenance personnel and systems to improve  safety, efficiency, and well-being.

SHEL(L) Model

Model are used to understand human factor  as a framework around which human factor issues can be structured. SHEL(L),PEAR, Dirty Dozen  S - Software H - Hardware L - Liveware E - Environment                                         Liveware  is at the center of the model, is   the most critical and flexible component in the working  Environment and subject to considerable variations in performance and suffer many limitations.                           Physical size and shape.  In the design of workplace and equipment, body measurements and movements is considerd , which may vary according to factors such as age, ethnicity and gender. Human Factors inputs is provided  in the design process, and data for these inputs are available from anthropometry, biomechanics and k...

Information Processing Limitation

Human information processing  have limitations.   AMT requires support such as reference  to written material (e.g. manuals). Attention and Perception -  A proportion of ‘sensed’ data may be lost without being                              ‘perceived’.   Failing to  perceive  something  which   someone  has said to you, when you are concentrating on something else, even  though the words would have been received at the ear without any problem.  Information processing system has  ability  to perceive   something (such as a picture,                       sentence, concept, etc.) even though some of the data  may be missing.  Danger - people can fill in the gaps with  information from their own store of knowledge or experience, and this may lead to  t...
