6 6 0 - Introduction THE AIM OF THIS DOCUMENT IS TO SUPPORT THE CARACTERIZATION OF A NC WHICH IS A DEVIATION FROM THE DEFINITION OR FROM A REQUIREMENT OF A PRODUCT. THIS DOCUMENT SCOPE IS LATECOERE PARTS AND PRODUCTS THE WRITING OF CUSTOMER CONCESSIONS (WHICH FOLLOW THE NCR) IS DESCIBED IN CUSTOMER DOCUMENTATION THE REQUIREMENTS OF NCR (Non-Conformity Report) have to allow the fulfillment of - SECURITY REQUIREMENTS (EASA) - AIRLINES REQUIREMENTS Scrap 1 NCR = ∑DATA to choose between : Use As Is Repair E0018MM_GB_issue_E

7 7 1- Scope of manual  A well-written NCR should allow a quick understanding of the defect, for that description must be clear, simple and precise, in order to reduce round trips between the originator of the NCR and the TD MRB  correct disposition  This document is intended to be a working tool for Originators who should refer regularly to it as a "checklist" to avoid the phenomenon below.  The NCR description is under the responsibility of the Redactor ‘s department and should allow a well understanding of the NC with respect to the parameters needed by the Technical Directorate (TD) (see §5.5) MRB DESIGN STAFF ORIGINATOR NCR datas Avoid return NOTA: More returns are done more NCR is chronophage and expensive: Don’t make returns to Originator only for spelling mistakes or form problems E0018MM_GB_issue_E

8 8 1- Scope of manual (cont.) It is also useful for - having a common language between:  Quality which ensures non-conformities control and writing of AE (Avis d’Evènement)  Engineering & Quality inspectors creating non conformities  Latecoere MRB Engineering which proposes and validates repair solutions.  Suppliers also generating non-conformities - Homogenizing the content of NCR between the various programs - Providing main needed data to Airlines which operate the airplanes E0018MM_GB_issue_E

9 9 2- Workflow to manage a Non-Conformity E0018MM_GB_issue_E

10 10 3. Glossary of acronyms and definitions S = edge distance : distance between the axis of the rivet or the bore and a edge of part DR = distance between the axis of a bore and the beginning of the fillet or of bending radius of a part. e = thickness e P = Pitch is the distance between the 2 fasteners axis or 2 holes axis E0018MM_GB_issue_E

11 Manual Acronyms (cont.): To know the direction of flight Forwarddamages H = Depth: the distance between the part surface and the bottom of a drilling hole AF = distance between the part surface and the top of the fastener head (> 0 or <0) Indicate: the front of plane or frames numbering and if necessary The plane side (LHS or RHS) here AF<0 E0018MM_GB_issue_E

12 12 4- « GOLDEN RULES » TO WRITE AN NCR  The description made in the NCR should be self sufficient to allow the DT MRB to treat non-compliance without asking for further information.  This is an official document involved in obtaining the individual airworthiness certification of the aircraft.  An NCR may have an impact on the subsequent assembly process and on the in-service airline repair "The NCR should be sufficient to itself" E0018MM_GB_issue_E

13 13  The basic rule is that each non conforming part affected to an MSN must have its own NCR number.  In the case of non affected parts, one can group NC parts on the same NCR if:  All parts have the same reference  there’s the same type of damage on all parts  It leads to same dispositions  the same classification for all NC is expected But if later parts are affected to different MSN for major classification, then the original NCR should be split into several NCR for each affected MSN.  Avoid using abbreviations or fanciful names (exp: sea snake).  The concession must be understood by any potential reader.  If you use an abbreviation write the whole word followed by the abbreviation the first time it appears in the NCR.  Be consistent about the use of words in French or English.  Avoid the use of references to other documents. If yes, make sure that:  This document is not confidential  It will be possible to give information to the airline  It is available on the intranet for another Latecoere staff.  Avoid adding personal information such as telephone number, people on photos The rules for good writing :: 5.1 General rules concerning the declaration of an NC Report (NCR):: E0018MM_GB_issue_E

14 Procedure to realize a NCR CLARIFY and IDENTIFY the defect in its environment CLARIFY and IDENTIFY the defect in its environment LOCATE defects on schemes LOCATE defects on schemes IDENTIFY the defect in the proposed defects list IDENTIFY the defect in the proposed defects list GIVE technical parameters necessary for engineering department in the NCR GIVE technical parameters necessary for engineering department in the NCR. E0018MM_GB_issue_E

15 CLARIFY and IDENTIFY the defect in its environment: Inform points below: Name of NC parts  Ex: skin, doubler, frame, stringer, fitting.... Reference numbers of simple part and impacted assembly drawing  Dwg No.: FXXX XXX XXXX Location: Specify the impacted side(s) (RHS or / and LHS, Frame XX, Stringer XX…) The type of damage ex: elongated hole, tool mark... NOTA: Avoid duplicated information (risks of later mistakes) E0018MM_GB_issue_E

16 LOCATE defect on a schema: Use the points below to locate the defect(s) : 3 levels of localization: Level 1: show the complete product with the affected area Level 2: show the sub-assembly of the product with the position of non-compliance Level 3: Zoom of parts / assembly with non-compliance in its environment. Specify : the direction of flight if frames are not numbered the outer face and / or inner face, or the side (RHS, LHS) The frames and stringers serve as references example: Fr4, Fr5 for frame 4 and frame 5, St13 RHS, St10 LHS for stringer 13 of rhs and stringer 10 of lhs … An identified surface may serve as a reference. Drawing extracts, views, sections are useful. Use cross sections to show stacks of parts, thickness, edge distance,... if necessary. Using of photos: The photos will be used when non-compliance cannot be appropriately described through drawings. When photos are used ensure that: They are taken on the product concerned by the NC. The defect surrounding area is clean (no machine chip, sealant drop…). They are taken from a suitable position to focus on NC. Each photo should be accompanied by a clear title and be readable on black and white print. A wide shot photo (for environment) and then zoom on the default (for details). The defect can be directly dimensioned on the photo. It should be completed with aircraft references (direction of flight, reference of frames & stringers, sections,...) as requested above. E0018MM_GB_issue_E

17 Identify the defect in the proposed list : It should be noted that the real defect may be a combination of several defects listed in the list proposed in Chapters 6.1 and 6.2. E0018MM_GB_issue_E

18 Give in the NCR technical parameters necessary for TD MRB team Once the defect(s) identified in the proposed list, provide in the description of the NC the necessary parameters corresponding to these defects, in order to find the best repair solution. These parameters have to show the "SHOULD BE” and the “IS" of the defect area. If the defect is not in the list of defects, provide the key parameters listed below. SUMMARY OF POSSIBLE KEY PARAMETERS FOR THE NCR: Defect location + part numbers Defect position in space Dimensions of the defect thicknesses pitches Edge distances Radius distances Fastener references Defect creation REPAIR = WILL BE « SHOULD BE » « IS » E0018MM_GB_issue_E

19 Rules on dimensions to measure and indicate mminch Drill holes are inspected & measured in millimeters to or in inches to Фxx.xx(mm) Фyy.yyy(in) Ф xx.x(mm) Ф yy.yy(in) All requested actual measurements impossible to do directly on product will be discussed with the TD MRB team in order to decide how to proceed. Drilling Boring  Units of measurement are millimeter or inch (Depending on customer drawing set) The boring diameter is reamed and controlled in millimeters to 10-2 or in inches to 10-3 E0018MM_GB_issue_E

20 20 Requirements for measurement accuracy (continued): 1/10 mm for low edge distance and pitch 1 mm for the other edge distance and pitch 1/10 mm for thickness Respect as much as possible the drawing rules, dimension proportionalities. Link the measures to well known references as geometrical references (part edge or web, steps…) rather than to location of installed fasteners. Verify values coherence on schemes Rules on dimensions to measure and indicate (cont.) E0018MM_GB_issue_E
