Subject: Comments on Avn Maintenance DEX
The following comments require the attention of the authors:- Gordon Robb - LSC Group Ltd - Comments on DEX (D011):- aviation_maintenance Date: 2008/03/10 10:36:16 Revision: 1.145 Paragraph Topic Problem Recommendation Disposition Related DEXs Reference to Product Operational Information- This is not correct. It is the Product Configuration Information that should be available. See Def Stan 05-10 for PCI definitions OR 649A/649HB OR the APSI definitions of the PLCS AAM Change to Product Configuration Information where POI is used throughout the DEX Business Overview Introduction Last para states "product information between the two organisations ensuring that the aircraft product data is accurate." The use of Product data is INCORRECT. Change to Product Configuration Information Business process Reportable Activities Use of Stock Code is incorrect Use National Codification Bureau designation of Stock Number throughout DEX Business Information Message wrapper Use of data is incorrect Change to information Business Information Requirements Engineering_instruction Routine Technical Instructions - is this RAF jargon [or RAF CE Instruction etc]. The use of Special Technical Instruction & Servicing Instructions are not 'routine' Change para to read Technical Instructions. See Def Stan 05-123 Pt 4 for guidance Business Information Requirements Engineering_Instruction - Last sentence - EIs are the main authority for making changes, although changes to part numbers may also be effected by a design amendment Design Amendment DO NOT change Pt. No's. This could be a case of using a 'bad expression' "amendment". An amendment in the Design world is a minor change to the design that does not change the Pt.No. A Modification leaflet WILL change the Pt.No. Change design amendment to 'modification leaflets' Business Information Requirements Resource_part.supplier_code Note - The supplier code is the code identifying the manufacturer/supplier. Often CAGE code. .. CAGE is incorrect. NCAGE is the correct term: See NCB web site http://www.isisweb.mod.uk/wwwisis/navigate.do Change to NCAGE throughout the DEX Message Controlled_exchange - This activity reports when there is any removal of a serviceable reportable item from one aircraft for installation on another aircraft This activity is usual referred to as Ac Robbing Certificate [RAF Form 7213-a] Insert reference to the 'Robbing certificate' Representing a reportable item Business information PLCS representation 'The Stock Code, e.g. NSN is a definition of the fit, form and function, or interchangeability of a part. This is an incorrect statement FFF disappeared [correctly] in the 1980s and was replaced with interchangeability. See DS 05-970//123 Amend sentence to read "The Stock Number, e.g. NSN is a definition of the interchangeability of a part. Representing change of Part Number, Serial Number, and NSN Business information Used of Form, Fit Function is incorrect Change to interchangeability Representing change of Part Number, Serial Number, and NSN Business information The Unique Identification (IUID) from the Department of Defense (DoD) is another identification of the Product_as_individual <http://docs.oasis-open.org/plcs/dexlib/R1/stepmod/data/modules/product_ as_individual/sys/4_info_reqs.htm#product_as_individual_arm.product_as_i ndividual> and is represented by an Identification_assignment <http://docs.oasis-open.org/plcs/dexlib/R1/stepmod/data/modules/identifi cation_assignment/sys/4_info_reqs.htm#identification_assignment_arm.iden tification_assignment> represented by template #7 and #15 assigning_identification <http://docs.oasis-open.org/plcs/dexlib/R1/dexlib/data/templates/assigni ng_identification/sys/cover.htm> and classified as "UID" (urn:plcs:rdl:std:UID) <http://docs.oasis-open.org/plcs/dexlib/R1/dexlib/data/refdata/sys/class _exp.htm#urn:plcs:rdl:std:UID> This statement requires amending. The DoD refers to it as Item Unique Identification [IUID]. This DEX incorrectly uses the correct abbreviation and the wrong description in a number of areas. Representing deferred activities Business information The statement "There will be occasions due to operational constraints when these tasks need to be delayed or brought forward due to damage or stress.' seems inappropriate. If it stress related or damaged there is usual one course of action in that the activity is brought forward Change to read "There will be occasions due to operational constraints when these tasks need to be brought forward due to damage or stress."
