Theserequirements apply to Manufacturers, Distributors, and Special Processors providingparts or services for Cessna Aircraft Company when this document is specified byinclusion on a purchase order (PO) or contract issued by Cessna Aircraft Company.In the event that the PO or contract conflicts with the requirements of this document, thePO or contract requirement will supersede.2.0 INTRODUCTIONCQRS flows down the quality system requirements of Code of Federal Regulation,Federal Aviation Regulation (FAR) 21.137, and defines Cessna’s additional qualityrequirements. It also advises suppliers that their quality system, facilities, and those ofany sub-tier supplier are subject to site evaluations by Cessna, Cessna customers andregulatory agencies.The Director/Manager of Cessna Aircraft Company Integrated Supply Chain QualityEngineering must approve deviations to the requirements included herein. Requests fordeviation shall be documented and submitted to Cessna Supply Chain QualityEngineering (SCQE). Contact information can be found at www.supplier.cessna.com.2.1 Cessna Supplier ApprovalSuppliers’ quality systems shall comply with the latest revision of the appropriate qualitysystems standard along with the Cessna specific quality requirements within thisdocument. Documented evidence of compliance to the appropriate quality managementsystem (QMS) standard along with a successful onsite Cessna Aircraft or TextronAerospace Company supplier quality audit is required prior to production.Documented evidence may be in the form of registration by an accredited registrar whois approved for registrations to the required aerospace standard and listed in the OnlineAerospace Supplier Information System (OASIS) database (www.iaqg.sae.org/oasis) oran affidavit confirming compliance based on an internal audit or second party audit.Cessna approval is required for all Manufacturers, Distributors (Pass Through Distributor)and Special Processors who supply aircraft parts or services. Interior fabric/textilesuppliers are exempt unless they provide structural, flight critical or restraining systemitems. Suppliers providing commercial product (not specifically designed for theaerospace industry) may also be approved without showing compliance to therequirements outlined in the document.All written and oral communications with the supplier as well as the supplier’sspecifications, procedures and reports shall be in English.Questions regarding quality approval shall be directed to Cessna SCQE.

Cessna Aircraft Company Page 2Aircraft DivisionWichita, Kansas 67277CQRS Rev. N2.2 Cessna Supplier Re-ApprovalSupplier approval shall be re-evaluated at least every five years by Cessna SCQE. Reapprovalwill be based on the supplier’s quality performance, changes in the supplier’squality system, delegated inspection authority or changes based on the needs of thebusiness.The supplier shall notify Cessna if the primary contact(s) for quality changes. It is theresponsibility of the supplier to provide to Cessna a written statement of any changes inthe supplier’s ownership, location or changes that may alter the overall effectiveness ofthe supplier’s quality system, including revisions to quality management systemcertifications. This notification shall be sent to Cessna SCQE. Contact information canbe found at www.supplier.cessna.com. Upon receipt of this notification, Cessna willdetermine what re-approval(s), if any, is required. The supplier shall have a documentedprocedure on how to notify Cessna of these changes.2.2.1 Supplier RelocationSuppliers shall provide advanced written notification to Cessna SCQE of any intent torelocate the production, manufacturing, repair or overhaul of parts/assemblies. Suchnotification shall include, as applicable, the following information:a) Current and proposed facility locations.b) Proposed part/assembly numbers, specifications, special processes andtooling.c) A proposed transition timeline with a risk mitigation plan that preventsdisruption in the supply and/or support of parts/assemblies.d) Any additional information required by Cessna to understand business and/orlegal impacts.Cessna SCQE shall review the notification and advise the supplier on lead-timesrequired for approval activities. Cessna SCQE and the supplier shall agree on a timelinefor the transition. Quality Management System approvals shall be in place prior to themovement of actual production of part/assembly work.2.3 Supplier Performance MonitoringCessna evaluates supplier performance in the areas of quality, reliability, schedule,collaboration and cost as applicable. Performance tracking is accomplished utilizingCessna’s Supplier Tracking And Rating System (STARS). Supplier-specific STARSquality data may be reviewed at www.supplier.cessna.com. Instructions for accessingand interpreting the STARS information are also available at the site.The STARS Quality rating is based on either a parts per million defective (PPM)calculation or the number of rejects. The Tier One or Tier Two status is determined bythe total number of receipts in the previous calendar year. More information may befound at www.supplier.cessna.com. Nonconformances submitted and approved via

Cessna Aircraft Company Page 3Aircraft DivisionWichita, Kansas 67277CQRS Rev. NSupplier Rejection Disposition Reports (SRDR) prior to shipment or source inspection willnot be included in the PPM calculations.The supplier is responsible for complying with quality system requirements noted hereinand for meeting performance expectations. Failure to comply with requirements or toachieve an acceptable performance level may result in an on-site audit or additionalsource inspection oversight at the supplier’s expense. Cessna reserves the right to debitor invoice supplier accounts to compensate for inspection or related activities that takeplace as a result of Cessna directed inspections.3.0 QUALITY SYSTEM REQUIREMENTS3.1 ManufacturersIn addition to other requirements within this document, Cessna requires manufacturers ofmaterials, parts and assemblies to have a quality management system that complies withthe (AS/EN/JISQ) 9100 Quality Management Systems – Requirements for Aviation,Space and Defense Organizations. Copies of the AS standard can be purchased fromSAE International at www.sae.org.3.2 Special ProcessorsA list of all processes requiring Cessna SCQE approval can be found atwww.supplier.cessna.com/cgi-bin/quality/capability_view.pl.Any suppliers performing work on Cessna design-controlled part numbers to thespecifications at the website above will require approval by Cessna SCQE prior toconducting any processing. Requests can be made at the above website to addadditional suppliers to Cessna’s approved special processor list. Additions will be madeat the discretion of Cessna. However, Cessna reserves the right to rescind approval ofspecial processors at any time at Cessna’s sole discretion. Some special processesrequire that the supplier obtain additional facility qualifications from Cessna Material andProcess (M&P) Engineering. M&P Engineering approval requirements are containedwithin the applicable process specifications.Special Processors must have a quality management system that is compliant to(AS/EN/JISQ) 9100 Quality Management Systems –Requirements for Aviation, Spaceand Defense Organizations or accredited to AC7004 Quality Management SystemRequirements for Nadcap Accreditation. Approval by Cessna SCQE will involve an onsiteaudit of the supplier’s QMS and the applicable special processes. The QMS auditmay be waived for suppliers accredited to (AS/EN/JISQ) 9100, ISO 17025 or AC7004.The ISO 17025, General requirements for the competence of testing and calibrationlaboratories, scope of accreditation must cover the Nadcap scope of accreditation and befrom an approved NACLA/ILAC (National Cooperation for LaboratoryAccreditation/International Laboratory Accreditation Cooperation) accreditation body. Inaddition, special processors shall achieve and maintain Nadcap/NUCAP (Nadcap Users

N4.3.2 Supplier Required Periodic Tooling InspectionThe supplier shall ensure that tooling which controls or checks the final configuration ofCessna design-controlled parts and assemblies are inspected a minimum of once peryear to ensure compliance to tool design, master control tools and to Cessnaengineering requirements. The results of these inspections shall be recorded andrecords retained per CQRS quality record retention.In addition, the supplier shall address any damage, missing tooling components or wearto tooling prior to producing parts to ensure compliance to Cessna engineeringrequirements.For spares tooling that is used infrequently, a 100% part inspection may be used in lieuof tooling inspection to determine compliance to Cessna engineering requirements or atooling inspection may be performed prior to each use.4.3.3 Cessna Requested Periodic Tooling Inspection ReportsCessna SCQE will notify the supplier’s quality representative by letter when Cessnarequires the supplier to complete a periodic tool inspection. The notification will betransmitted by e-mail, facsimile or mail and consist of a list of the tools. The supplier’sauthorized quality representative will date, stamp and sign the letter certifying theperiodic inspections are complete and show compliance to tool design, master controltools and Cessna engineering requirements. The supplier shall return the letter toCessna SCQE via e-mail, facsimile or by mail. The supplier’s quality representative willfacilitate having the tooling and tooling log inspection stamped to note the completion ofthe periodic inspection as applicable. Supplier’s records of the Cessna RequestedPeriodic Inspections shall be retained per CQRS quality record retention requirements.4.4 Part IdentificationCSTI029, Identification: Inspection and Special Processes, may be flowed down by PO,drawings or other Cessna engineering. The following applies when CSTI029 is notrequired. Parts that are not Cessna design-controlled shall have the supplier partnumber applied. Part marking shall be accomplished by permanent ink stamping of theparts when the identification method is not specifically regulated by the drawings,specifications or other documents. For all Cessna design-controlled part numbers,acceptance by the supplier of items to be delivered to Cessna shall be indicated bymeans of the supplier’s final acceptance stamp on all parts. All McCauley Engineeringdesign-controlled part numbers shall be positively identified. This identification shallinclude McCauley part number, PO number or serial number, date of manufacture andinspection stamp. Products having an insufficient or unsuitable surface to be individuallyidentified will be bundled, if possible, or placed in an identified container. An identificationtag, with all required information, shall be attached to the bundle or the container.

Cessna Aircraft Company Page 7Aircraft DivisionWichita, Kansas 67277CQRS Rev. N4.5 Raw MaterialsCessna M&P Engineering approval is required for purchases of all aluminum andtitanium wrought materials that are outlined in the Cessna Procurement SpecificationQPLs (Qualified Products Lists). This approval is required for materials to be used forproduct under Cessna design-control. The QPL controls material size, as well as thesource of manufacture.Note: The definition of wrought material for the purpose of this paragraph doesnot include material used to produce forgings and castings.If a supplier wants to request an additional mill be added to a QPL, the request should beforwarded to Cessna M&P Engineering through the supplier’s Cessna Supply ChainManagement Representative or contact.4.6 Military/Standard Specification HardwareSuppliers shall deliver military/standard specification hardware (AN, MS, NAS, etc.)compliant with the latest document revision, unless otherwise specified by Cessna.4.7 Evaluating Product4.7.1 Sampling PlansSampling plans utilized for Cessna product shall preclude the acceptance of lots withknown non-conformities (these plans are also referred to as c = 0 sampling plans).4.7.2 Test Reports and Certifications for Materials, Parts and ServicesWhere test reports and certifications are utilized as the basis for accepting materials,parts and services for Cessna product, the supplier shall ensure that the data in thosedocuments are acceptable per applicable Cessna requirements.4.8 Quality AccessThe supplier guarantees the right of access to their facilities and quality related data toCessna Aircraft Company, Cessna customers and regulatory authorities.

Cessna Aircraft Company Page 8Aircraft DivisionWichita, Kansas 67277CQRS Rev. N4.10 First Article InspectionThe supplier shall perform a first article inspection on a part from each first lot shipmentof parts to verify all engineering characteristics. Variable gauging shall be used whenpossible. If a first article was delivered as part of an experimental order, a copy of thefirst article inspection report shall accompany parts delivered on the first production PO.Suppliers shall comply with AS9102, Aerospace First Article Inspection Requirement, forall first article inspections. The FAIR shall be retained as a quality record at thesupplier’s facility and a copy shall be submitted to Cessna Aircraft Company along withthe first lot shipment.Unless specifically directed by the PO, FAIRs are not required for Cessna parts that arederived from standard catalog hardware (as defined by AS9102), provided that the partshave not been modified. Re-identification of standard catalog hardware to a Cessna partnumber does not constitute a modification that would require a FAIR.If applicable, a Cessna source inspector may verify FAIRs at the supplier’s facility. Theverification of the part conformity will be noted on Cessna’s X-159 Source InspectionForm or by direct data entry into Cessna’s electronic IP system.4.11 Nonconforming Material4.11.1 Cessna Material Review Board (MRB) DispositionA Cessna MRB disposition is required when material is found to depart from POrequirements and cannot be reworked without affecting fit, form or function. To obtain aCessna MRB disposition, the supplier shall initiate a Supplier Rejection DispositionReport (SRDR) for articles under Cessna design control. SRDR applications are to besubmitted online and can be found at www.supplier.cessna.com. Instructions for the useof the online application are also available at the website.Upon receipt of a disposition to an SRDR, the supplier shall perform rework/repair inaccordance with Cessna’s SRDR disposition. The supplier’s authorized qualityrepresentative must indicate that the rework/repair has been completed in accordancewith all requirements by the application of their inspection stamp impression on theSRDR form. Each article shall be identified with the SRDR number provided by theonline application. If this identification is impractical due to product size, identificationshall be in accordance with Section 4.4. For serialized assemblies, under Cessnadesign-control (i.e. assemblies with S4053-1identification placard), the supplier maytabulate the applicable SRDR numbers on a log and include the log in the assemblydelivery document package in lieu of stamping the assembly and associated detail partswith the SRDR number. A copy of the log shall be attached to the assembly.A copy of the completed SRDR form shall be included with the shipment of the product.The applicable SRDR number(s) shall be referenced on the shipping documentation.
