Job Task Planning and Organizing
  • Aircraft assemblers and aircraft assembly inspectors plan their tasks to respect the deadlines of an overall production schedule. They have input to the schedule through monthly and weekly planning meetings which determine the sequencing of daily activities which will contribute best to meeting the schedule's requirements. The task sequence is generally determined by the workers themselves, although they make adjustments to take into account delays from parts breakage or supply delays. In some hangars, work priorities are supervised by a lead hand. Since many parts of the production process depend on the work which preceded it, there is a high degree of integration with the work plans of co-workers.Although much of the work is routine, aircraft assemblers and aircraft assembly inspectors need to be able to react quickly to factors which can cause production delays or quality problems.

Decision Making
  • Decide whether to scrap, swap or fix a defective part. (1)
  • Decide from which suppliers to order replacement parts. The decision takes into account likely availability, the location of the supplier and the length of time it will take to fill the order. (2)
  • Decide whether to file a part to make it fit better on the fuselage. (2)
  • Decide in which order tasks should be performed to work best with the production schedule. (3)
  • Decide whether a part meets specifications, taking into account many technical details. (3)

Problem Solving
  • Broken or damaged parts are slowing down the process. Make efforts to obtain replacement parts as quickly as possible since the slowdown can affect many workers whose tasks depend on the part being installed. (1)
  • A part does not fit properly. Check to see if it is the right part and check technical manuals for installation directions. If the cause of the poor fit cannot be found, complete technical query forms (TQF) followed by pre-installation failure reports. (2)
  • A part which has been installed is not operating correctly at the final assembly and testing stage. Consult engineers to assist in the analysis of factors which could have caused the problem. (2)
  • Parts of the production team are behind schedule, causing delays for other workers. With the approval of the supervisors, leave own work for a short period to provide assistance to the team which needs it. (2)
  • A part is operating but is not functioning exactly as stated in the technical manuals. Revisit the installation procedures to see if a step has been missed, if there is an error in the manual or if equipment is malfunctioning. (3)

Finding Information
  • Find parts equivalents and specifications in supplier manuals. (1)
  • Consult engineers to clarify information about non-conformity issues. (2)
  • Find information about modifications to drawings by cross-referencing engineering change notices, engineering memoranda and operational sheets. (3)
