CONCESSIONS T300 TREATMENT and / or CHECK
CHECKAERO is also dedicated to concessions treatment (T300 analyses and check for Composite and Metallic parts) conforming to constructors process flow chart.
CHECKAERO ensures its customers following activities:
Task 300 concessions analyse for metallic and composite structures
CHECKAERO will perform Task 300 activities by analysing concessions on stress issues and validating the proposed technical repair, and using SAP PAC (ANDS Task). Task will be:
- Understanding of technical answers to concession
- Check of quality of description, design answer and suffixes
- Stress assessment:
- The divergence and/or the repair has no stress impact
The concession can be signed immediately (« No stress impact »)
- The divergence has a stress impact that can be assessed by stress engineering judgement
The concession will be signed («stress engineering judgement»)
- The divergence has a stress impact that requires a proper stress analysis
The concession will be signed through providing a stress analysis
The Stress Analysis Report is included as a COS document
- The divergence has a stress impact that can be passed by comparison with a previous MSN concession.
Task 300 concessions check for metallic and composite structures
CHECKAERO will support the closure of Task 300 by checking it for all identified critical concessions (customer priority list), and using SAP PAC (ANDS Task). Tasks will be:
- Support customer concessions teams and bring stress expertise to support the closure of Task 300
- Complete a detailed check of concessions before Task 300 closure
- Identify critical deviations and prepare a corresponding detailed concessions summary to help customer concessions team to close T300
The checks are defined in a concession check list (customers check list or check list provided by CHECKAERO).
They comprise:
- Kind of defect (composite and metallic parts defects)
- Data declared in the concession compared to the theoretical data
- Check of the repair
- Check of the stress analysis
The result of the initial check will be documented in a check sheet detailing the discrepancies found.
The task is completed with a follow-up check after correction (iterations), and all concessions checks are listed in a smooth detailed follow-up file, with the possibility to easily display Key Performance Indicators (KPI).
Remark: One important assumption is that CHECKAERO assume that methods used have been previously validated between customer and final client. Only advices and recommendation about methods used will be given by CHECKAERO.
Based on the following inputs / outputs:
Inputs:
To carry on these activity properly, inputs necessary are (list non exhaustive, can be completed at the beginning of the work between customer and CHECKAERO):
- List of critical concessions with ID number
- Request for Concession
- COS (concession assessment document) done for the concession task 300 to be checked with all files necessary (isami session for example)
Content of the COS:
- Concession general information, Drawing with defect location, Repairs Drawing
- Analysis location, GFEM, Load Loop, tools and report with method.
- Stress analysis before concession, Stress analysis after concession
- Access to stress justifications (static and F&DT if necessary) realized for the area impacted
- All documents referenced in the stress report
Outputs:
- Delivery form summarizing concessions checked and documents provided by Checkaero (check list, COS...)
- Check sheet describing discrepancies found during check
- COS
- Follow-up files with Key Performance Indicators
Concession team will be organized as:
- CHECKAERO Focal Point and customer interface for:
- Easy exchange and information requests
- Concessions input
- Working priorities
- Weekly status : progress, forecasts, held activities
- Stress Team
- Managed by a Concessions group leader
- Skills interface : Stress approver
- Exchange through VPN or FTP line
- Access to Customer concessions software (SAP for example)
Our activity will ensure our customers:
- Time and cost saving by iteration reduction
- Expertise
- Conformity to constructors procedures
- Reactivity
- Possibility to treat documents in emergency
- Flexibility
- An individual follow up per document to be checked
- Possibility to make visio conference (by Skype or Webex) or physical meeting with your dedicated checker to solve particular points
- Security by our experience and our resources network composed only of high qualified engineers with more than 8 years experience.
