Rev. A1.INTRODUCTIONSupported by our suppliers, Moog has developed a reputation for quality, performance, anddelivery that has helped us to become a leading supplier of aircraft flight control systems andcomponents. Achieving a satisfactory and repeatable standard of workmanship for machinedmetallic parts is vital to Moog’s continuing ability to meet and exceed our customers’expectations, leading to continued growth and mutual success in the marketplace.CAGE CODE94697Page 8 of 85Use of Data Restricted—See Page 1.MRQ52620
Rev. A2.PURPOSE2.1Scope & IntentMoog continually strives to deliver the highest quality products that meet performance, cost, andon-time delivery goals. However, many visible irregularities, although not aesthetically perfect,conform to the drawing requirements and do not adversely affect the design intent. Thisdocument will assist in the judgment of whether a machined metallic part for Moog Aircraft Grouporders conforms to the drawing and relevant specifications. The standards, guidelines, andinstructions within this document are intended to apply to machined metallic parts and assembliesand associated special processes.This document supplements engineering drawings and purchase order requirements for make-toprint machined metallic parts. In all cases, reference must be made to the order of precedencepresented below:Drawing PO (including S-Clauses) Workmanship Standard SQR-1Given the order of precedence, nothing in this standard can override a requirement orspecification called out on the drawing or PO.The primary intent of this document is to align suppliers and Moog to the criteria and methods forjudging whether parts conform to the drawing and relevant specifications. It is therefore expectedthat both suppliers’ and Moog’s Quality Engineers, Product Engineers, and Receiving Inspectionwill use this document as the basis for process optimization, control plans, inspection plans, andidentification of non-conforming parts with visual irregularities. Note, per Section 2.2.5, Moog andits customers maintain sole MRB (Material Review Board) authority when dispositioning parts thathave been deemed non-conforming.2.2General Guideline Notes2.2.1 Procedures, Training, and Inspection RecordsSuppliers must develop inspection/operating procedures and provide regular training toinspectors/operators based on this workmanship standard. Inspections must take place in anarea with a minimum light level of 750 LUX (70 foot-candles). Suppliers are expected to retaintraining records and record the results of all inspections.2.2.2 DimensionsUnless otherwise specified, applicable dimensions within this workmanship standard arepresented in U.S. inches. Metric equivalents are presented in parentheses for general guidanceto those organizations using these units of measure; e.g., .25” (6.3mm), .0003” (0.008mm), etc.2.2.3 Foreign Object Debris/DamageParts shall be free from FOd larger than 25 microns (approximately .001 inches, viewable at 3.5xmagnification) measured along the largest linear dimension, as measured per AS598 or ISO4407.Suppliers shall adopt FOD control and inspection methods to ensure this requirement and therequirements of AS9146. FOd which is isolated and potentially introduced frompacking/unpacking, and/or is airborne and can be removed with slight airflow, shall not be causefor rejection.CAGE CODE94697Page 9 of 85Use of Data Restricted—See Page 1.MRQ52620
Rev. A2.2.4 Part Handling, Packing, and PreservationPackaging shall be adequate to protect the components during transportation, handling, andstorage at all stages and shall include provisions for the protection of corrosion sensitivematerials. Packaging containers shall be appropriate for the size, weight, and fragility of thecomponents being packed. To prevent many of the types of defects and irregularities described inthis document, part-to-part contact shall be avoided at all stages, including manufacturing,inspection, handling, storage, and shipping.2.2.5 MRB Authority and ReworkThis document is not a delegation by Moog to suppliers of make-to-print machined parts for MRB(Material Review Board) authority. MRB is the formal disposition of non-conformities to drawing(or other design technical data) requirements and can only be performed by Moog or itscustomers. This document is intended solely as a guide to determine when a feature should beconsidered non-conforming. Where doubt exists over the interpretation of an irregularity, includingwhether rework-to-print is allowable, it shall be considered non-conforming and additional adviceshall be sought from Moog engineering via an SR-type NC (SRID). Whenever an irregularity iscaused by an event that may cause an over-stress condition, such as dents caused by dropping apart, it shall be considered non-conforming and advice shall be sought from Moog engineering viaan SR-type NC (SRID).2.2.6 ExamplesThroughout this document, examples of typical irregularities found with Moog parts are includedto provide clarity on disposition criteria and methods. Wherever specific part numbers are used,the intent is not to indicate the subject irregularities are unique to those specific parts, but ratherto always refer the reader to the drawing and all associated specifications in order to dispositionwhether the part is Non-Conforming.2.3Magnification RequirementsThe table below summarizes the magnification needed to inspect and verify each type ofirregularity. Where a higher magnification level is deemed necessary (e.g. based on criticality ofparts or tolerances specified on the drawing), this is specified in the appropriate Appendix of thisdocument.Irregularity TypeMagnification RequirementsA. Surface Corrosion and PittingVisual check (1X); if Non-Conforming, inspect at up to 10Xto validateB. Cosmetic IrregularitiesVisual check only (1X)C. BurrsNo burrs visible at 10X (maximum)D. External ContouringVisual check only (1X)E. Special ProcessesVisual check only (1X); up to 10X in certain limited casesCAGE CODE94697Page 10 of 85Use of Data Restricted—See Page 1.MRQ52620
Rev. A3.DEFINITIONSEdge BreakThe condition at the intersection of two or more machined features(external or internal) achieved either by application of manual,chemical, or machined operations. Unless otherwise specified, therange of allowable Edge Break condition is specified in the title blockof the drawing. E.g. “.002 Max Edge Break”.IrregularityAny area that is visibly different from the surrounding surface of thesame material, verified at 1X.Non-ConformingA Non-Conforming irregularity indicates that the part does not meetthe requirements of the drawing. When this applies to images withinthis document, images will be bordered in red.Non-Conforming parts will be entered into Moog’s TIP QA qualitysystem and dispositioned by the relevant MRB authority, e.g. Use,Return to Vendor etc. This includes SR-type NCs (SRIDs) submittedby suppliers.Part-to-PrintA Part-to-Print irregularity indicates that the part meets therequirements of the drawing. When this applies to images within thisdocument, images will be bordered in green.ReworkLocalized area on a surface where an irregularity has been removedor touched up. Reworked areas can show evidence of mechanicalblending. A Part-to-Print rework must conform to all GD&T callouts onthe drawing (Surface Finish, Flatness, Perpendicularity, Parallelismetc.)ShallShall denotes an intended mandatory requirement.Sharp EdgeThe intersection of two or more machined features (external orinternal) requiring no Edge Break greater than a specified value or bya size variance over feature length. The intent is to precludeapplication of manual, chemical, or machined Edge Breaks beyond theminimum required to remove hanging burrs. Unless otherwisespecified, the maximum allowable Edge Break for a Sharp Edge is.0010 inches. E.g. “Size variance over feature length to be .0005 maxper hole.”Should & MayShould & May both denote non-mandatory provisions and are used toshow guidelines.SmoothMeeting the drawing surface finish requirement and any drawingmismatch allowance or, when there is no mismatch allowance,exhibiting no surface discontinuity detectable with a plastic pick.WillWill denotes an intended mandatory requirement. It is synonymouswith shall.CAGE CODE94697Page 11 of 85Use of Data Restricted—See Page 1.MRQ52620
