Study Notes

Ethiopian Planners

Ethiopian Planners are the new spirit of Africa.

Production Planning

The organization needs a system for planning work, personnel, tools, equipment, materials, maintenance data and facilities for safe maintenance work
Planning maintenance tasks and shifts needs to consider human performance limitations.
If tasks need to be handed over due to a shift or personnel change, relevant information must be communicated between outgoing and incoming personnel.

Production Planning Process

The steps for the production planning process are illustrated in a flow chart
The process involves maintenance pre-event preparation, hangar event preparation, induction to project completion, maintenance execution, and post mortem completion.
Resources and facility information is needed

Analysis of the Work Order to Ensure Maintenance Remains Within the Approved Scope

Analysis of work orders ensures the requested maintenance is within the approved scope of approval.
Responsibilities for decision-making processes are defined
Assessment of work scope, both initial and changes to the initial scope, is assessed
Examples of maintenance activities deemed basic maintenance are provided.
Verification of the maintenance work package is done by the customer.
Control of maintenance document availability and updates is required.
A smooth process is needed between production planning, maintenance planning and hangar maintenance.

Necessary Resources and Outsourcing Contractors

Procedures for establishing necessary resources before work commences, and for outsourcing contractors, are required.
Procedures for organizing maintenance personnel are necessary, as well as providing all necessary support during maintenance.
Consideration of human performance limitations is essential.
Planning of critical maintenance tasks is required.

Man-Hour Planning Process

A one-month and a one-year maintenance man-hour plan need sufficient staff to plan, perform, supervise, inspect, and monitor availability.
Specific attention needs to be paid to individuals performing different roles in a particular maintenance check.
The man-hour planning system needs to clearly indicate the level of the mechanics/technicians.
The quality monitoring function on man-hours should be sufficient to meet the requirement.
The one-month plan is from the first to the last day of each month.
The one-year plan is from July 1st of the current year to June 30th of the next year.
The one-year plan needs to be prepared before June 15th of the year.

Factors Taken into Account in Planning

The total available headcount in Aircraft Maintenance is based on Human Performance Limitations, Complexity of Work, and Vacation
Training, Hand Wash, and Break Time are also considered factors.
Working conditions, Facilities, Weather, and Type of Shifts affect Human Performance.
The planning revision process is needed to ensure Ethiopian Airlines stability.
One-month man-hour plans need to be reviewed and updated.
One-year man-hour plans need to be reviewed at least every 3 months and updated when necessary.

Notification to the Accountable Manager of Deviation Between Workload and Man-Hour Availability

The Accountable Manager and the Manager MRO Quality Assurance & Safety need to be notified of any 25% variations between the workload and the available man-hour over a period of one month.

Type of Planning (Man-Hours Availability Versus Workload)

Technicians' availability by specialties, levels of privileges, and coordinators/support staff (B1/B2) needs to be adequate for scheduled maintenance work.
Sections responsible for planning should ensure staff required for quality control functions are adequately available per day and per shift.

Hangar Visit Plan Versus Man-Hour Plan

The maintenance man-hour plan should relate to the aircraft hangar visit plan for base maintenance of aircraft.
The planning of man-hours should be related to the planning of hangar space.
Sufficient manpower needs to be available in overlapping three-shift basis, and staggered day-off schedule.
