WHO WE ARE P.t.A. is operating since June 2011, but really exists since 2004, having acquired the PRAE sas society, of which has maintained the organic, the operating site and all the H/W and S/W systems for the design, analysis and devolopment of all the activities. P.T.A. consists of a group of qualified technicians' with 30 years experience acquired prevalently in the aeronautical sector and it is able to offer activities in the field of the structural design, engineering issues and elettroavionics, of the engineering service, of the production engineering and the certification with the support of the most advanced SW for design and calculation. P.T.A. works also in the revision field and maintenance of components and aircrafts, using qualified operators and the support of the opportune methodologies and equipments. The narrow cooperation with the companies of the Moreggia Group, working in the field of the aeronautical buildings, makes possible the "verticalization" of the product, from the project to the part construction and assembly. P.T.A. has a Quality System in conformity with the requirements of ISO 9100:2009, is “tirth part” certified from Rina spa as “design of parts for aeronautical applications”. P.T.A. joined the “Distretto Aerospaziale Lombardo”, which incorporates several companies operating in Lombardy in the aerospace sector, with the aim of fostering collaborations and synergies between companies that share knowledge in the field of high technologies. The company's structure is reported in the following organization chart

STAFF P.T.A. has for the design 50 resources, of which more than one third are aeronautical, mechanical and electronic engineers, whilst the remaining are aeronautical and electroavionics experienced technicians. Revisions and maintenance operators are all of more than 30 years experience, and their number changes according to the demands, being most professionals who work to contract. In detail, P.T.A. resources are divided into the following categories: DESIGN: N. 2 electroavionics designers and drawers N. 15 Structural/Electroavionics Methodists N. 12 structural and mechanical designers and drawers N. 2 Avionic systems analyst N 3 Service Engineer N. 3 Specialist in Transmission, Hydraulics and Modification Design (Laurea Ing. Aeronautica) N. 1 Specialist in Service Bulletin (Laurea Ing. Aeronautica) N. 3 Configuration controls N. 2 stress analysts N. 3 Certification Engineer N. 1 material management experts N. 3 Management and Segretariat REVISION AND MAINTENANCE: Mechanical operators Structural operators Electrical operators Engineers

HARDWARE & SOFTWARE P.T.A. disposes of: Hardware: N° 2 Workstations IBM Risc/6000 N° 30 Personal Computers (fixed/portable) Software: Catia V4/V5 (3D/2D drawing) CCDraft (2D drawing) CADRA (2D drawing) Patran/Ideas/Nastran (FEM) Office NX MACH 1 Design P.T.A. also has a link with Leonardo Company , therefore it can draw towards the cadam bookshops, towards the Part List Database and towards the SAP system, besides the possibility of working in " terminal server “ mode.

EXPERIENCES Resources P.T.A. srl. have worked on several models of helicopters and airplanes, among which:

WHERE WE ARE P.T.A. srl has registered office in Turin. The operating office is located in Gallarate in Corso Sempione 15/A, in a short while distance from the Leonardo Helicopters plants and enough near the Leonardo Aircraft plants. Our staff is able to operate in the P.T.A. offices as far as in customers sites, including the ones placed in areas different from the mentioned neighbouring ones, as truly more turned happened.

WHAT WE DO P.T.A. performs activities of aeronautical design and aircraft revision. In these years of activity P.T.A. has principally worked with Leonardo Helicopters and Leonardo Aircraft in the context of the structural and electroavionics design and in that of revision/maintenance. A few significant examples of the activities done: Starting from SOW, P.T.A. completely designed the structural and electroavionics reconfiguration of the CH47C plus UAE and Libya helicopter Coordination of the activities of repair and revision for the CH47 plus UAE and Libya helicopter reconfiguration Engineering activity for the solution of the inconveniences noticed on the in service helicopters as EH101, AW129 CBT and NH90. Design development for the elettroavionics reconfiguration of AB412 Helicopters Design development of structural parts for AW109, AW139, AW129, AB412, AB212, CH47,SH3D Design development of mechanical parts (rotors and Transmission) for AW109, AW139, AW129, AW149 and Aw169 Design repair for the in service helicopters Execution of calculations for the structural analysis and relative final reports emission Technical reports and test reports for avionics systems integration Development and drawing of electrical wiring and schemes Job cards for production engineering Technical bulletin for AW109, AW139 Tools design Advice in the world of the civil aviation certification and military qualification
