3272-9 FACTHUM (9.6)

The alerting system for an important system failure should be. an aural warning. a flashing visual signal, preferably red. a dolls-eye indicator.

If you are given a task that you are unsure of you should. consult the appropriate approved data. ask someone who has done it before. consult type course notes.

What is the most important means of communication in aircraft maintenance engineering. Written. Implicit. Verbal.

The most effective form of communication is. verbal communication. written communication. explicit communication.

Asynchronous' communication includes. immediate voice communication by radio link. technical manuals, memos, Advisory Circulars and Airworthiness Directives. face-to-face communications.

A good practice for a shift handover is for shifts to be specifically rostered so there is an overlap of. 2 - 3 hours. 5 - 10 minutes. 20 - 30 minutes.

A good shift handover should include details of. tasks that have been completed; persons who carried out the tasks; tasks to be carried out and general company and technical information. tasks that have been completed; tasks in progress, their status, any problems encountered etc.; tasks to be carried out and tools required to carry out the tasks. tasks that have been completed; tasks in progress, their status, any problems encountered etc.; tasks to be carried out and general company and technical information.

What constitutes a good work handover?. A written and verbal account of the work done. A written documentation of the work done. A verbal account of the work done.

When carrying out a visual inspection, an engineer is likely to make a parallax error when. inspecting a component using a 5x or 10x magnifying glass. using precision measuring instruments such as a vernier gauge or AVO meter. nothing.

The main disadvantage of carrying out critical inspections under very bright artificial light is. glare. shadows. filtered light.

Itemized checklists should be dealt with. in any order, provided all steps are completed. item by item, in order, to cover every step diligently. as memorized.

When a person moves from a poorly lit area to a well lit area, what is the minimum time they should allow for the eyes to adapt?. 7 minutes. 7 seconds. 30 seconds.

In the 'slips, lapses and mistakes' definition of errors, a mistake would typically occur at the. storage (memory) stage. execution stage. planning stage.

In the 'slips, lapses and mistakes' definition of errors, forgetting to replace an engine cowling would be considered a. mistake. lapse. slip.

Which type of human error is easiest to correct?. Constant error. Reversible error. Variable error.

A violation in an aircraft maintenance procedure. is usually carried out with the best intentions from a genuine desire to 'get the job done'. is always considered an act of vandalism or sabotage. is always carried out to satisfy some personal need, often unrelated to the actual task.

Which part of the SHEL model is most difficult to protect from errors by 'designing out' or to 'work around'?. Liveware. Software. Environment.

What part of the SHEL model would the aircraft design fit into?. Liveware. Hardware. Environment.

The 'error chain' theory refers to. a chain of errors within an organizations can be investigated, and similar errors prevented by determining a common link between them. a company is only as good as its weakest employee or employees, and removal of that/those employee from the chain should prevent errors. errors are caused by a chain of linked events, and the breaking of one link in the chain will prevent the error.

What part of the SHEL model would the writing and interpretation of maintenance manuals fit into?. Hardware. Software. Environment.

The SHEL model of human factors takes into account. Software, hardware, environment and liveware. Software, hardware, efficiency and liveware. Software, hardware, environment and location.

An experienced engineer is fitting a valve. A required seal is not fitted. What type of error is this?. Knowledge based. Rule based. Skill based.

The difference between a mistake and a violation is. a mistake is less serious than a violation. a violation is not deliberate. a mistake is unintentional and a violation is deliberate.

An engineer is working on a wing and kicks a spanner off into an engine cowl and breaks a sensor. This is. knowledge based error. skill based error. rule based error.

An experienced engineer fits the wrong seal during a routine component change. This is. skill based. rule based. knowledge based.

Whilst working on an aircraft a spanner placed on the wing surface is kicked off and subsequently falls into an open engine cowl, breaking off a sensor connector. This is an example of. a skill based error. Murphy's law. a punishable occurrence.

A mistake is. a deliberate departure from the rules. an intentional act of sabotage. an unintentional error.

A violation is. an unintentional error. a deliberate departure from the rules. an intentional act of sabotage.

Troubleshooting is. rule based. skill based. knowledge based.

Visual inspection by an 'experienced' maintenance engineer is. knowledge and rule base behaviour. skill and knowledge based behaviour. skill and rule based behaviour.

On a task that is complex, an engineer uses his own procedures due to pressure. This is legally termed. modification. initiative. violation.

When carrying out a risk assessment. a hard hat should be worn. it is necessary to identify where equipment/procedures might fail. Nothing.

Risk assessment and management is. reduction of risks to a tolerable standard and monitoring the situation. the investigation of risks and totally removing them and the monitoring of new work practices. choosing a cheaper supplier or manufacturer for parts.

Engineers often work on raised platforms, ladders etc. What dangers can this contribute to?. Staging may be made of wood. Ladder may slip and man falls. Two workers may be carrying out maintenance on the same lift.

An engineer who has developed his or her own method of performing a complex task. should be commended for his/her resourcefulness. is performing a rule based behaviour. is violating on a regular basis.

An engineer is performing a task in less than ideal conditions in order to meet an operational deadline is. committed a routine error. committing a situational violation. making a rule based slip.

If an engineer forgets to fit a seal to an engine drain plug, he or she has. made an error of commission. committed a violation. made an error of omission.

What happens when you break the 'chain of error'?. Accident happens. Pilot submits report within 72 hours. Accident does not happen.

What is a latent failure?. A mistake that has already been made, but has not yet caused an accident. Receiving bad instruction from a manager who is out of touch with maintenance. A failure which could not have been predicted.

What is the difference between error and violation?. Violation is deliberate, error is not. Error is deliberate, violation is not. No difference.

A type 1 visual inspection error occurs when. a faulty item is missed. a good item is incorrectly identified as faulty. a duplicate inspection is not carried out.

The hub of the SHELL model of human factors is. enviroment. hardware. liveware.
