FORKWORD The often complex nature of collaborative projects makes the operation of a Concession and Production Permit system much more involved than the more commo
7、n “one contractor to one customer1 situation. Collaborative Projects take many forms. The contractor could be two or more single source companies with defined design authority. There could be a lead company or a joint management organisation which would present a single focal point on contractual an
8、d technical matters. The customer could be, or be represented by, one or more military or civil Authorities, or a combination of both. The Authorities could be represented by a single focal point to assess non-conformances on behalf of the individual bodies. The unique identification of responsibili
9、ties for technical decisions and quality acceptance is essential, as is reciprocal recognition of such decisions by all parties. Whatever the system, responsibilities for technical and commercial decisions for contractor and customer must be clearly defined. By the very nature of AQAP and Civil Auth
10、ority requirements they allow such variety in responsive company procedures that incompatibility between these procedures is very common in the context of company-to-company operation. It is therefore anticipated that for collaborative projects most companies will initially have to move away from th
11、eir traditional Concession/Production Permit procedures and create either a single inter-companies procedure or, as a minimum, ensure full compatibility.

APPLICABILITY The recommendations of this paper are made on the basis of anticipated requirements for Production Phases of collaborative projects. It is equally essential to control configuration and non
13、conformance during Development but this requires more flexibility in the handling of hardware and software which does not conform to a standard which, in itself, may be frequently changing. Often such a non-conformance is a necessary development step and does not reflect on the quality of design or
14、 manufacture. The framework provided by this paper could be applied to a Development situation. The acceptance of a Group 1 category concession see under Definitions, so often a point of contention between Contractor and Authority, becomes so cumbersome and difficult to control and administer on col
15、laborative projects that it should, under normal circumstances, be exceptional in its application. It may be a point of contractual arrangements to exclude the use under normal circumstances. During Development it is necessary to consider Group 1 concessions due to the nature of the phase of work an
16、d such cases should be agreed with the appropriate Authority taking into consideration the requirements of the programme and the possible effects on Qualification. During negotiation of contracts the guidelines of this paper should be considered in conjunction with applicable national requirements.

DEFINITIONS Definition of Non-conformance The individual
18、national requirements for types of non-conformance are based on the following broad definitions: Concession Permission granted by qualified personnel acceptable to the customer if required to use under determined conditions a limited quantity of material or parts already manufactured which do not co
19、mply with the product specification. -Production Permit Permission granted by qualified personnel acceptable to the customer if required in advance of manufacture, to use material or make parts which will not conform to the approved proauct specification. This permission will be granted for a planne
20、d quantity only. In some countries and under certain conditions the concession is used to cover the requirements of a Production Permit. Concessions are then further defined, depending on their severity and the effect the non-conformance will have on the use of the product by the customer or on othe
21、r technical requirements as follows: GROUP 1 Some concessions will impose limitations on flight, performance, life or interchangeability or other major quality aspects at customer level. Such concessions constitute the highest category. They must be recorded and traceable, both on the part-itself an
22、d included in the delivery documents. GROUP 2 Other concessions which do not impose any limitation at customer level but which must be uniquely recorded and traceable both on the part itself and by records, but not necessarily in the delivery documents, except where the part concerned is despatched
23、as a spare. GROUP 3 Those concessions covering items wnich do not comply with requirements and do not fall within the definition of Groups 1 or 2. Such concessions are normally not uniquely recorded or traceable. Copyright Association Europeene des Constructeurs de Materiel Aerospatial Provided by I

Classification Three levels of recorability are used to define the three concession groups: GROUP 1 Must be recorded to the customer. GROUP
25、2 Must be recorded to final assembly or delivery records retained and traceable. GROUP 3 Must be recorded locally at Inspection/Test stage These classifications are not totally definitive unless there is a clear understanding of what imposes a “limitation“ on the customer. The question of “limitatio
26、n“ is confused by the fact that because of different systems operated by different users and manufacturers, something which imposes a limitation on one user may not impose any limitation on another. As an example, in a collaborative project one user may wish to be responsible for his own maintenance
27、 and overhaul, another may wish to return everything to the supplier company. Certain non-conformances affect future repairability and in the first case this would impose limitations on the user and require recording to him. In the second case there is no limitation on the user and recording within
28、the supplier company is sufficient. What does and does not constitute a limitation must be agreed for each particular project at the outset. A further consideration in the use of “limitation on the user“ concessions is that it is logical for the manufacturing company, and its military or civil Autho
29、rity if appropriate, to judge the non-conformance, the expertise and background information being with them. On collaborative projects the user will sometimes be the collaborating company and country and it is not envisaged that they would readily accept the decision of the other nation made on thei
30、r behalf regarding the acceptability of limitations. Should circumstances be such that the operation of a system for acceptance of Group 1 concessions is considered in the commercial interests of the parties concerned, then this should be negotiated to the specific requirements.

Cosmetic Non-Conformance It is common practice to record to the cust
32、omer non-conformances where appearances are affectea such that it could cause concern to the user and reassurance is required that a full technical assessment of the non-conformance has been made, confirming that no limitation applies. In such cases it is proposed that a Group 2 concession is raised
33、 and relevant information is extracted and copied to the customer in the log book. Inter-Company Recordability There are occasions when a non-conformance, whilst not imposing a limitation on the customer, could affect interfaces with, or higher assembly by, a collaborative partner. A system must be
34、agreed between partners covering these circumstances and the transmission of appropriate information and instructions. 5.4. Material Review Board MRBI All parts subject to concession action should be identified and positively controlled at all stages of the process. Group 3 concessions should be han
35、dled at Inspection stages to a system acceptable to, and auditea by, the appropriate Authority. The formal assessment of Group 1 concessions (if applicable, Group 2 concessions and Production Permits requires the raising o.some pro forma giving, as a minimum, the following information: a Unique iden

If there is a decis
39、ion to “use as is“ or use after repair the authorised signatories must indicate their acceptance of the decision. Quality systems normally initiate corrective and preventive action from the data available from the point of recording non-conformances. Some of these will be raised for concession actio
40、n and further information may become available at this point to supplement that already logged. Monitoring of concession data can serve as a check that the preventive and corrective actions resulting from defect analysis are appropriate and effective. 5.5. Part Markinq The requirements of various Cu
41、stomer/Authorities differ with regard to Part Marking. Any non-conformance must be recorded through the various subsequent stages to final release, where full details of any Group 1 if applicable concession, Group 2 concession or Production Permit must be available. This could be achieved by marking
42、 the part or by some form of labelling. Parts shouldenot be marked unless it is essential for the contractor to do so in order to maintain integrity of the system or there is a specific customer requirement. Where there is a specific Customer/Authority requirement to mark the part subject to concess
43、ion then agreement must be reached on the information required and the method of marking. A contractor must ensure that there is an identification system to assure the required traceability but must examine critically the need to mark the part. 5.6. Reciprocal Acceptance It is logical to operate a s
44、ystem on a multiple partner or multiple Customer/Authority project only where there is a firm agreement on reciprocal acceptance of Concession and Production Permit decisions, both between companles and between Authorities. As it is proposed to restrict concessions to those not imposing limitations
45、of the customer, this should not pose a problem. 5.7. Records Records should be retained for a period to be agreed between all parties concerned.
