Sébastien Scala

I provide my engineering services in handling Aircraft non-conformities.

My domain of expertise throughout the steps of the NCs:

- the initial analysis of the non-conformity and the decision to be taken about the process to handle it: to scrap a single part, to raise a concession or a DQN, or to rework as per drawing.

- the selection of the most appropriated technical answer to the the non-conformity, considering the industrial aspect as well as the rules of design, and the stress (static and F&DT) limitations.

- the detailled stress justification: COS document under SAP.

- The process analysis from a quality point of view: fullfilling AP2006 procedure, choice of suffixes, ...

A400M - Centre Fuselage Lower Shell & Rear Fuse.
Stress focal point for all the A400M concessions & DQNs in PAG.

AIRBUS A400M – FAL A400M – MAP Fuselage

Stress Responsible of the MAP Fuse at FAL Sevilla. Works involve the stress signature of the stress assessment task of all the FAL concession for the Fuselage, including Nose, Centre and Rear Fuses + Sponson, WFF and CWB.
Also MAP Focal Point for Station 72 (Assembly of the Wing to the Centre Wing Box).
Extensive use of SAP (SP1, PAC, PDA).

AIRBUS A400M – Nose Front Bulkhead – WPM53112

Stress Leader on the Nose Forward Bulkhead and Nose Front Cap packages using mainly the MTS method (Airbus Stress Manual) and the Airbus France Tools such as ACSA and ASSIST. The structure to be designed, optimised and justified was made of 2 double curved stiffened panels, including skin, stringers, stiffeners and the radial fuselage frame 1. In addition, fittings and system brackets were checked in both static and dynamic. Static Test stress prevision.
