About this file
This document contains an engineering change proposal (ECP) file related to the Bradley A4 Production Contract - Amendment 0005, a solicitation issued by the Department of the Army Materiel Command TACOM Life Cycle Management Command. The ECP file includes 17 proposed engineering changes and technical updates to drawings, specifications, and test procedures for the Bradley A4 vehicle. If approved, the changes would update the technical data package to reflect issues identified during previous production and testing, incorporate approved design variances, and allow the optional use of F-24 fuel. Most of the proposed changes are intended to confirm previously authorized configurations or administrative updates and are not expected to impact current production of the Bradley A4.

FOM-W7818 Final Drive Lifting Tool and Driveshafts Wing Cap Redesign and Revised Driveshafts for Torque Requirements for Bradley Family of Vehicles, AMPV and MLRS
| FOM-W8606 | Towing & Tie Down Provisions | Replace 4 point provisions with 2 point provisions. For front and rear. Remove shackles | Incorporated via AMD-0002 | |
| FOMX1019 | Towing & Tie Down Cleanup | FOMX1019 is a Class I ECP to incorporate updates to Towing and Tie Down (T&TD) drawings as well as performance specifications, systems specifications and a process specification for A3 Bradley Fighting Vehicles (BFV). This ECP also addresses feedback from first article findings from the first production kit build (TTD KIT 57K7948) [REF1], BFV Towing & Tie Down Install Verification [REF2], Request for Variances (RFVs) and Problem Reports (PRs). The changes stem from production feedback and involve updates to paint notes, material notes, stenciling and weld callouts (outlined in the Description of Change section). This ECP also updates distribution statements, NHA blocks and formatting. | Incorporated via AMD-0005 | |
| FOMX1038 | Approved use of either F-24 or JP-8 fuel | |||
| within the Bradley A4 Performance Specification. | Bradley A4 ECP FOM-X1038 is a Class I ECP that updates PSpec requirements, PSpec quality assurance provisions, and FIR to add F-24 as a fuel type and allow F-24 to be used for production testing. |
This ECP also includes changes to the PSpec to correct minor errors and formatting that do not change the nature of the requirement
| (2) Production Impact: Production Impact: Since most of the changes confirm the actions previously authorized by the noted variances, they confirm the as built or planned configuration. Although there were additional administrative changes included in ECP that were not reflected in variances, we believe they do not impact production. The only Production impact in response to the ECP will be to replace the variances with the updated drawings. | Incorporated via AMD-0005 | ||
| FOMX1040 | BFV A4 PTO Updates | This class I ECP is to update the 12294771 drawings to capture the as-built configuration of the production M2A4 and M7A4 vehicles. These drawing errors/issues came about during the early M2A4 / M7A4 production procurement and builds. They were addressed at the time with variances. The NOR updates are based on their respective approved Requests for Variance (RFVs). Additionally, the missing special tool drawing, 12577973, called for on the 12576295 PTO is being released with this ECP. |
(2) Production Impact: Since most of the changes confirm the actions previously authorized by the noted variances, they confirm the as built or planned configuration. Although there were additional administrative changes included in ECP that were not reflected in variances, we believe they do not impact production. The only Production impact in response to the ECP will be to replace the variances with the updated drawings. *Note: the tool 12577973 is not applicable to Production. (Phuong Hoang 11-10-2021)

| L21M5003 | CIV/BUSTLE ECP | FOM-L21M5003 is a Class 1 ECP created to fix issues related to the CIV mounting provisions and bustle armor as well as address production request for variances (RFVs) for A3 and A4 Bradley vehicles. The drawing changes vary per drawing; the changes are outlined in the Description of Change and Need for Change sections. This ECP consists of four drawings with three concurrent NORs and one is hanging. | |
| (2) Production Impact: Since most of the changes confirm the actions previously authorized by the noted variances, they confirm the as built or planned configuration. Although there were additional administrative changes included in ECP that were not reflected in variances, we believe they do not impact production. The only Production impact in response to the ECP will be to replace the variances with the updated drawings. | Incorporated via AMD-0005 |
