When thereis a job task that is before us, a lot of other things come into consideration that we may not always think about. How the job task is completed, when influenced by certain factors, may have a detrimental affect on the outcome of the task. Stress from home or work situations can affect how we work and cause us not to perform to the best of our abilities. Mental distractions can cause us not to complete all the steps required to complete the task in a satisfactory manner. Pressures to get the job done can cause mistakes that are very costly in dollars and human lives if we do not pay attention.

Getting plenty of rest helps to do the job in the manner that appears to be easier. Our environmental conditions definitely have an affect on how we perform. Working at cold temperatures, in the rain, in the heat, and other undesirable working conditions affect our performance. Being healthy supports our physical condition to perform any task that we may be called on to do.

Protective clothing ( Gloves, goggles, ect.)
Personal safety equipment (ventilation equipment, ect.)
Proper tools ( electric tools verses air tools )
Identification ( tagging, safety streamers, ect. )

Money
Parts
Man Power
Facilities
In order to perform any job task we must have the resources available to us

17. Was the job task performed to be equal to the original?
Each person maintaining or altering, or performing preventative maintenance, shall do that work in such a manner and use materials of such a quality, that the condition of the airframe, aircraft engine, propeller or appliance worked on will be at least equal to its original or properly altered condition.
Must do the work in such a manner that the part being worked on is at least equal to the original condition. This is an area that is lacking in most instances due to the fact that most owners and operators want the least inexpensive way of completing the task.

18. Was the job task performed in accordance with appropriate data?
Each person performing maintenance. alteration, or preventative maintenance shall use the methods, techniques, and practices prescribed in the manufactures maintenance manual or data acceptable to the administrator.

Each person performing maintenance, alterations, and preventative maintenance shall use the tools, equipment, and test apparatus necessary to assure completion of work in accordance with industry practices.
Methods, Techniques, and Practices acceptable to the industry have been developed by the manufacturers of the product. We are required to perform to those standards.

20. Did I perform the job task without pressures, stress or distractions?
Reevaluation of the job task may need to be considered if the job was accomplished under these conditions.
As a reminder the aircraft must be in a condition for safe operation.
Reevaluation is a must if we determined that the work accomplished was affected by any of these human factors.

21. Did I reinspect my work or have someone inspect my work before return to service?
Perform the inspection as to determine whether the aircraft or portions thereof under inspection, meets all applicable airworthiness requirements.
Two eyes are better than one. Many times we can be looking at a discrepancy and not see it because we have looked at it numerous times. Added insurance is the best policy.

22. Did I make the proper record entries for the work performed?
Each person who maintains, performs preventive maintenance, rebuilds or alters an airframe, aircraft engine, propeller, appliance or component part shall make an entry in the maintenance record of that equipment.
Major repairs and alterations shall be entered on a form ( FAA Form 337).
Federal Aviation Regulation 43 requires each person that performs any task make an appropriate record entry.

23. Did I perform the operational checks after the work was completed?
Must determine satisfactory performance in accordance with the manufacturers recommendations.
When completing the job task it is always very important to do an operational check of the system or systems that might have affected the repair or modification that may have taken place. It is better to find the problem at that time and take the corrective action necessary before the product is approved for return to service.

24. Am I willing to sign the bottom line for the work performed?
If the work performed on the aircraft, airframe, aircraft engine, propeller, appliance, or component part has been performed satisfactory, the signature, certificate number, and the kind of certificate held by the person approving the work.
The signature constitutes the approval for return to service only for the work performed.
In many cases it has been noted that theperson approving the work for return to service, did not always perform the work. The work that was accomplished may not havemet all the standards as required. Therefore, the person approving the work for return to service held the reponsibility for the work performed. The regulation requires the person performing the work to make the appropriate entries in the aircraft records.

25. Am I willing to fly in the aircraft once it is approved for return to service?
The ultimate test for the work task accomplished.
Assures confidence in the work performed.
Increases reliability. Decreases liability.
Maintains public trust.
Maintains integrity.
The ultimate test to the job task completion is the fact that we will stand behind the work that we accomplish and would be willing to support that fact by flying in the aircraft. If we would not consider flying in the aircraft, ourselves , we shoud reevaluate our work standards and perform accordingly.
