Question

Based on the knowledge you have gained through the readings in this module, answer the Module Review Questions listed below. These questions were chosen to enable you to classify the three categories of maintenance checks (Learning Objective #1), describe the functions of Production Planning & Control (Learning Objective #2), research aircraft maintenance Phase Checks (Learning Objective #3), and explain the contents of a phase check package (Learning Objective #4). When responding to these questions, please place yourself in the perspective as an Aviation Maintenance Manager.

1.Discuss the three categories of tasks in your own words.

2.Research a Phase Check on an aircraft of any airline and write about the way the airline performs the Phase Check.

3.Describe some necessary elements that PP&C must arrange for in order to execute the PP&C package.

4.Outline the three functions of Production Planning & Control (PP&C) Department.

5.Explain the elements that the Aviation Maintenance Manager needs to know to adjust future planning.

Explanation / Answer

1. Three categories of maintenance check are:

i) Daily Check: This check is known by several common names such as maintenance Pre-flight, service check or overnight to name a few.Basic requirement is that airplane remains trustworthy.Examples of daily check are : Check fluid level,Visually inspect tail skid shock etc.

ii) A Check: It is next high level of schedule maintenance.and is normally accomplished at designated maintenance center.'A' check also includes daily check.Examples of 'A' check are ; Check crew oxygen system pressure,lubricate nose gear retract actuator etc.

iii) 'B' check : It is slightly more detailed check of components and systems.In this check special equiplment and tests are required

There is another check which is called as 'C' check .It is an extensive check of individual systems and components for serviceability and function.

2. Phase Check is one of the variation of block maintenance.The number of scheduled maintenance tasks for a large airplane like the 747 are extensive, and this is particularly true for the higher 'C' and 'D' checks. Their accomplishment can remove the airplane from service for several weeks. This is considered unacceptable as it defeats the concept of removing the airplane from service in small, manageable blocks. One solution is to divide these higher checks into segmented blocks or phases.

A normal phase check include thorough visual inspection of specified areas, components and systems, as well as operational and functional check of specified components and systems.Each check includes the requirements of traditional lower check work items and portions of 'C' and 'D' checks at the required task intervals.Phase checks are typically accomplished at 200 to 800 flight-hour intervals, depending upon the work packaging plan and other airline operating variables.

3. Necessary elements that PP&C must arrange for in order to execute the PP&C package are :

i) Production data

ii) Vendor Information and its proposal

iii) Quality checklist

4. Three function of Production Planning & control department are :

i) Process Planning

ii) Ensure availability of materials, Machines and Equipments

iii) Estimating,loading and Scheduling
