Human Factor

Maintenance human factors training is part of a total system in managing human error, and discouraging procedural violations, in a maintenance organisation. It is an essential part of this system aimed at individuals engaged in 'hands-on' maintenance, support or management.  Without proper training, other initiatives related to error management and safety improvement (such as error reporting and investigation, better shift and task handover procedures, improvements in procedure design, etc.) will probably not be effective in the long term. An integrated approach, linking human factors training with organisational safety management and error management initiatives, is essential. Human factors training should not be something radically new - it covers basic safety principles and practices which should already be incorporated within a safety management and quality system, and how to ensure that work is carried out in a professional manner such that aircraft are released to serv...

Aloha and other major accident was preventable and could have  been avoided if any one of a number of things had been done differently.                                                                                  In some  cases, a number of individuals were involved and the outcome could have been  modified if any one of them had reacted or queried a particular action.                                             In each  situation however, the individuals failed to recognise or react to signs of potential  hazards, did not react as expected of them, or allowed themselves to be diverted  from giving their attention to the task in hand, lea...

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...

Working environment comprises the   physical environment,  social environment and  tasks that need to be carried out. Each of three component of working environment  interact themselve        • engineers are trained to perform various tasks;       • successful task execution requires a suitable physical environment;       • an unsuitable or unpleasant physical environment is likely to be de-motivating.  Various factors other than   Noise ,  Fumes ,  Illumination , Climate and  Temperature ,  Motion and Vibration and  Confined Spaces other physical influences include:        workplace layout and  cleanliness        and general tidiness of the workplace (e.g. storage facilities for tools, manuals and information,    tools retrieved procedure   provision and use of safety equipment  signage (such as non...

Safety In the Working Environment   Engineers should ensure that they keep the working environment safe.  Clutter,  rubbish, etc. is not only a nuisance to others, but can constitute a danger (e.g. a trip  hazard, fire hazard, etc.).  AMT should be careful when working on the  line not to leave objects when a job has been completed.  Foreign Object Damage  (FOD) is a risk to aircraft operating at an airfield. Types of  workplace hazards  include chemical, ergonomic, physical, psychosocial and general  workplace . ASC 2 of 2015 VRS   Work environment  is used to describe the surrounding conditions in which an employee operates.  W ork environment  can be composed of physical conditions, such as office temp., or equipment, such as personal computers. It can also be related to factors such as   work  processes or procedures. Safety When Working On Aircraft   Before operating or working on...

Error management:                    • prevent errors from occurring;                    • eliminate or mitigate the bad effects of errors Two components of error management as:                     (i) error containment  and                    (ii) error reduction. To prevent errors from occurring,                -- to predict where they are most likely  to occur and                -- then to put in place preventative measures.  Incident reporting schemes  (such as MORS) do this for the industry as a whole.  Within a maintenance  organisation, data on errors, incidents and accidents should be captured with a Safety  Management System (SMS), which should provide mech...

Emergencies may include: An injury to oneself or to a colleague; A situation that is inherently dangerous, which has the potential to cause injury  (such as the escape of a noxious substance, or a fire). AMO Role and Responsibility - To provide  appropriate guidance and training . The organisation should also provide procedures and facilities for  dealing with emergency situations and these must be adequately communicated to  all personnel. Maintenance organisations should appoint and train one or more first  aiders. Emergency drills are of great value in potentially dangerous environments. AME  should take part in these wherever possible.  Knowledge of  what to do in an emergency can save lives The basic actions in an emergency are to: Stay calm and assess the situation Observe what has happened;  Look for dangers to oneself and others; Never put oneself at risk. Make the area safe Protect any casualties from further danger...
