Production planning


145.A.47(a) Production planning

(a) The organisation shall have a system appropriate to the amount and complexity of work to plan the availability of all necessary personnel, tools, equipment, material, maintenance data and facilities in order to ensure the safe completion of the maintenance work.

AMC 145.A.47(a) Procedures

1. Depending on the amount and complexity of work generally performed by the maintenance organisation, the planning system may range from a very simple procedure to a complex organisational set-up including a dedicated planning function in support of the production function.

2. For the purpose of Part-145, the production planning function includes two complementary elements:
— scheduling the maintenance work ahead, to ensure that it will not adversely interfere with other work as regards the availability of all necessary personnel, tools, equipment, material, maintenance data and facilities.
— during maintenance work, organising maintenance teams and shifts and provide all necessary support to ensure the completion of maintenance without undue time pressure.

3. When establishing the production planning procedure, consideration should be given to the following:
— logistics,
— inventory control,
— square meters of accommodation,
— man-hours estimation,
— man-hours availability,
— preparation of work,
— hangar availability,
— environmental conditions (access, lighting standards and cleanliness),
— co-ordination with internal and external suppliers, etc.
— scheduling critical maintenance tasks during periods when staff are likely to be most alert.

145.A.47(b) Human performance limitations

(b) The planning of maintenance tasks, and the organising of shifts, shall take into account human performance limitations.

AMC 145.A.47(b) Limits and limitations

Limitations of human performance, in the context of planning safety related tasks, refers to the upper and lower limits, and variations, of certain aspects of human performance (Circadian rhythm / 24 hours body cycle) which personnel should be aware of when planning work and shifts.

145.A.47(c) Hand over

(c) When it is required to hand over the continuation or completion of maintenance tasks for reasons of a shift or personnel changeover, relevant information shall be adequately communicated between outgoing and incoming personnel.

AMC 145.A.47(c) Changeover/ handover procedure

The primary objective of the changeover / handover information is to ensure effective communication at the point of handing over the continuation or completion of maintenance actions. Effective task and shift handover depends on three basic elements:

— The outgoing person’s ability to understand and communicate the important elements of the job or task being passed over to the incoming person.
— The incoming person’s ability to understand and assimilate the information being provided by the outgoing person.
— A formalised process for exchanging information between outgoing and incoming persons and a planned shift overlap and a place for such exchanges to take place.
