1. BSC DE: Kyle Starck Status Date: 07/13/12 Approved by: H. Harr LCPT POC: L. Curtright Engineering Rate Enablers – Aft Body15) Section 47 PAX Floor Grid Build-Up and Installation Project Lead: Kyle Starck Customer: Mark Wigant / CS280 DE Status: • 1) 100% (ACD 3/1/12) • 2) 100% (ACD 5/11/12) • 3) 90% (ECD 5/196/11 TBD) • 3.1) 100% (ACD 6/6/12) • 3.2) 100% (ACD 6/11/12) • 3.3) 100% (ACD 6/13/12) • 3.35) 50% (ECD 6/196/27TBD) • 3.4) 0% (ECD 6/136/206/27 TBD) • 4) 0% (ECD5/24 7/13/12) • 5) 0% (ECD5/31 7/16/2012) • 6) 0% (ECD5/31 7/16/2012) • 7) 0% (ECD6/4 7/20/2012) • 8) 0% (ECD6/8 7/29/2012) Description / Problem Statement: • Locating floor grid properly per requirements to facilitate successful FA&D join results in excessive gaps between floor beam and frame fittings. • Current Floor Grid Assy tolerances fail to produce a product that will comply with end item requirements during installation. Target: • Reduce flow in Cell 280 by .25 day. Reduction of 76 man hours • Eliminate NC EPD, and 3.25 days of FAD rework during Section 46-47 join Proposal / Closure Criteria: • Incorporate improved datum and tolerance structure for floor grid assy • Increase MBD shim allowance between floor beam and frame fittings at STA 1618, 1644, 1670 and 1695 • Incorporation point: A/C 100 Process Info: • ELR 072169 – Rejected (no data) • ELR 072438 – Submitted with Data • ELR 073916 – Revised w/ Bus Case Last Now DE Project Y R Y R Risk: Cost estimates from Supplier Management Accomplishments: • Laser measurement of LN 82 frame fittings. • Gap measurements after floor instl of LN 82. Help Needed: • Need estimates from Supplier Management on costs for CDZ or MVO to build or replace tooling to deliver usable frames DE Plan: • 1) Floor grid installation dimensional analysis (ACD 3/1/12) • ELR 072169 and 072438 initiated by ME (ACD 3/15/12) • 2) Business Case for Aft Body impact (ECD 5/11/12) • 3) Evaluate increased shim allowance for 8 locations (ECD 5/19/12) • 3.1) Tech SAM Review (ECD 6/6/12) • 3.2) Compile package for existing frame RCA data (ECD 6/11/12) • 3.3) Evaluate need for workshop to resolve frame issue (ECD 6/13/12) • 3.35) Investigate costs for implementation of Frame corrective action (ECD 6/19/12) • 3.4) Return to Tech SAM for final determination (ECD 6/13/12) • 4) Preliminary Stress Assessment (8 locations) (ECD 5/24/12) • 5) Create Change Package / DE DWS (ECD 5/31/12) • 6) Baseline DE plan (ECD 5/31/12) • 7) Receive ERB Approval (ECD 6/4/12) • 8) Receive CCB3 Approval (ECD 6/8/12) LN 100 DE Release 3 1 7 2 6 4 8 5
