1. Illustrated Parts Data

   FAA Statement

   The FAA has reviewed the content of this catalog and, with the exception of those ATA chapters listed in STATEMENT OF FAA ACCEPTANCE CONDITIONS , have accepted its use in conjunction with the associated Engine Maintenance and Overhaul Manuals to assist operations in maintaining the V2500 Engine, Thrust Reverser, Common Nozzle and Tail Plug in a continued state of Airworthiness.

   This Illustrated Parts Data (IPD) is designed to assist operators of International Aero Engines products and their maintenance contractors in identification and requisition of replaceable parts and units. The Service Bulletin, Repair Scheme and/or Engine Manual are the authoritative documents on overhaul and repair procedures. Service Bulletins and Repair Schemes are the only documents used to notify the operators of changes to the effectivity of parts where additional parts are introduced to, or existing parts are deleted from an engine by a Service Bulletin or Repair Scheme. The relevant Service Bulletin or Repair Scheme is the authoritative document for the purpose of effectivity. Any conflict between the Service Bulletin, Repair Scheme, Engine Manual and IPD should be immediately notified to International Aero Engines AG.

The information contained in this document is the property of IAE International Aero Engines AG and may not be copied or used for any purpose other than that for which it is supplied without the express written authority of IAE International Aero Engines AG. (This does not preclude use by engine and aircraft operators for normal instructional, maintenance or overhaul purposes.)

2. General

   This Illustrated Parts Data (IPD) is designed to assist operators of International Aero Engines products and their maintenance contractors in the identification and requisition of replaceable engine parts and units. It has been prepared in accordance with ATA specification 2200 and S1000D.

   This IPD is intended as a companion, not a substitute, for the associated Service Bulletins, Repair Schemes and/or Engine Manual which are the authoritative documents on overhaul and repair procedures.

   Where additional parts are introduced to, or existing effective parts are deleted from, an engine by a Service Bulletin or a Repair Scheme, this IPD must only be used in conjunction with the appropriate Service Bulletin or Repair Scheme, as the relevant Service Bulletin or Repair Scheme is definitive for the purposes of determining the effectivity of parts (by which is meant the interchangeability/usage of parts).

   This IPD lists and illustrates the replaceable assemblies and the detailed parts for the following equipment installed on an aircraft.

   Engine – A527AQ02

   Engine – A527EAQ02

   Nacelle – A5100N2A

   Nacelle – A5100N21

   Nacelle – A5100N22

3. The Detailed Parts List Arrangement

   The Detailed Parts List (DPL) presents the engine and nacelle divided into sections, which match the breakdown used in the associated engine manuals.

   A further breakdown indicates the relationship of one part to another from the Next Highest Assembly (NHA) downwards. This is achieved by using indentations indicated by a number of dots (.) before the part name in the nomenclature as follows:

   1234567

   Installation

   . ASSEMBLY

   . ATTACHING PARTS FOR ASSEMBLY

   .. DETAIL PARTS FOR ASSEMBLY

   .. SUB ASSEMBLY

   .. ATTACHING PARTS FOR SUB ASSEMBLY

   ... DETAIL PARTS FOR SUB ASSEMBLY

   ... SUB - SUB ASSEMBLY

   ... ATTACHING PARTS FOR SUB - SUB ASSEMBLY

   .... DETAIL PARTS FOR SUB - SUB ASSEMBLY

   The attaching parts are preceded by ATTACHING PARTS and ended by * * * in the nomenclature of the DPL.

   Parts that have lost their individual identity by being fabricated into permanent assembly are not listed.

4. Effect. Column

   The Effect. Column gives guidance in determining effectivity (by which is meant the interchangeability/usage of parts) where additional parts are introduced to the basic build standard of an engine. Effectivity is indicated by a code in the Effect. Column. This code identifies:

   Interchangeability relationships of parts at an item number.

   Usage relationship of all parts within the figure.

   An explanation of the coding is included as APPENDIX 6 - EFFECTIVITY CODE to this introduction.

   NOTE

   Where additional parts are introduced to, or existing effective parts are deleted from, an engine by a Service Bulletin or a Repair Scheme, this IPD must only be used in conjunction with the appropriate Service Bulletin or Repair Scheme as the relevant Service Bulletin or Repair Scheme is definitive for the purposes of determining the effectivity of parts.

5. Number Required

   The number off against an item indicates the quantity required in the position shown and does not preclude the recurrence of that item in other positions. To assess whether or not a part recurs, reference should be made to the Numerical Parts List Index.

   Items which are not normally procurable but are listed for reference purposes carry the letters REF or RF in the Units per Assembly column. Items in a 'select from' range, such as shims are shown having the same number off as the nominal part.

6. Figure - Item Numbers

   Each part number listed in this catalog is allocated a Fig-Item number. These numbers are arranged in numerical sequence, with gaps to allow for insertion of additional items.

   The addition of a suffix letter to either a figure or an item number indicates a variant to the previous location.

7. Dimensions

   Where possible dimensions quoted in this catalog are expressed in both Imperial and Metric values. Conversion of Imperial thread size to Metric equivalent has not been made, this not being practicable.

8. Service Bulletin Identification

   When a part is introduced by a Service Bulletin (SB) the SB number will be included in the part description. To allow IPD users to identify whether the SB pertains to the Engine or Nacelle the SB number will be prefixed by:

   SBE for Engine Service Bulletins

   SBN for Nacelle Service Bulletins

9. Numerical Parts Index

   The index is broken down into parts, each part follows in numeric sequence and each part starts at page 1.

   The index is broken down into parts, each part follows in numeric sequence and each part starts at page 1.

   Letters A through Z

   Numeric 0 through 9

10. Revised Material

    Revisions to this catalog will be issued at frequent intervals to incorporate changes introduced by Service Bulletins and Repairs. A Service Bulletin List is included as Service Bulletin List to this introduction.

    The Service Bulletin and/or Repair number appears in the nomenclature of the affected part.

    The Service Bulletin numbers are preceded by 'SBE' or 'SBN' (see para 7), and the Repair numbers are preceded by 'VRS'.

    A REV bar placed in the left hand text margin indicates a change to the adjacent entry by the latest revision to the page. A REV bar adjacent to the page date will indicate that the text was unchanged, but material was relocated.

11. Vendor Components

    Accessory units, including Buyer Furnished Equipment (BFE), are covered in this catalog by call out of the end item and attaching parts together with any parts required for maintenance practices. A complete illustrated parts list for these units are included in the respective Component Maintenance Manuals.

12. Vendor Codes

    The Vendor Codes located in the Detailed Parts List identifies by unique codes the name and address of the vendors. A complete list of these codes used in the V2500 Vendor List (PN 2A4490).

13. Illustrations

    A. To aid location of parts and their location on the engine each illustration contains a location view, which is normally in the top left corner of the first sheet of the illustration.

    B. Insets are used and located by an arrow, then identified by a boxed alpha for the following conditions:

    Where space is not available to give sufficient detail at a given position on Sheet 1 of an illustration, the area is treated as an inset on a subsequent sheet or sheets of the same illustration.

    To avoid illustrating duplicate items within a figure, such as brackets.

    To aid with the identification and location of parts.

    C. Item number variants will not normally be referenced on illustrations.

    D. Clipping details are not normally illustrated but the item numbers are shown and bracketed together along with the clip position number (part of a circle with a number inside). The clip position number identifies a unique location for a clip position on the engine. It is also used in the associated engine manual.

    E. Modified items are only illustrated if there is an illustrateable difference introduced, (a change of material would not be shown unless the physical appearance altered). The modified item(s) are drawn and annotated in a modification box (a rectangular box containing the modified item(s) and an annotation defining the modification number, for example, (SBX XX-XXXX). Items introduced as additional to existing, as a modification need not be boxed except for clarity.

    The modification box is drawn as close to the pre-mod items as possible. Should there be insufficient room to include the box adjacent to the items modified, their position is indicated by an arrowed alpha and the mod box positioned in a space on the sheet and annotated with the boxed alpha inside the box.

    Should there be no room on the same sheet for the modification box, a statement will be included: 'FOR SBX XX-XXXX SEE SHEET Y' and the box will be drawn on a subsequent sheet of the illustration.

14. How to Identify an Item

    To identify an Item when only the part number is known.

    The item can be located by either using the CD-ROM search facility, with the part number. (From the result of the search facility, view each answer until the required location is obtained), or the item can be located as below:

    1. From the Numerical Parts List locate the part number and note the Chapter/Section/Subject, Figure and Item number.

    2. From the CD-ROM Table of Contents, locate the Chapter, Chapter/Section, Chapter/Section/Subject. Then locate the Figure and then Item number.

    3. For a description of the required part, refer to the Nomenclature column.

    4. To view the required part, locate the Item number on the Figure illustration.

    A. To identify an Item when the part number is not known.

    The item can be located by either using the CD-ROM search facility, with what information is known to locate the item. (From the result of the search facility, view each answer until the required location is obtained), or the item can be located as below:

    1. From the CD-ROM Table of Contents, locate the system in which the major assembly appears and find the Section Figure number.

    2. Locate the Figure number where this Major assembly is illustrated.

    3. Locate and note the Item number.

    4. Locate the Figure and Item number in the Detailed Parts List which will show the part number and description.

    B. Change Letter marking

    Part numbers marked on engine parts or packaging may include a change letter suffix. These alpha suffixes are used to track a certain level of manufacturing development for the part. The letters A through Z are used, with the exception of I, O, Q, and X. When all of the single letters are exhausted, the sequence continues with AA, AB and so on. A part may be manufactured to one level, “C” for example, but not incorporate the previous manufacturing improvement, “B”. In case like this the part would be marked “C-B”. Parts with no alpha suffix marking are manufactured with no changes and are known as NO CHANGE or N/C parts.

    The change letters have no effect on parts function or interchangeability, and are not listed as part of the part number in the IPD. Change letters should not be included when ordering spare parts. Change letters may occasionally be mentioned in Service Bulletins or Engine Manuals to differentiate parts if a service issue develops, and should not be removed from the parts or packaging.

15. Part Number Symbols

    1. X - Before a part number, shows that the part or assembly is no longer available from IAE.

    2. - (A Dash) Indicated the item is not illustrated.
