ABSTRACT
The safety is on the first rank in the aero industry. From this reason at the aero components fabrication, the great attention is given on precision and perfection of execution of all production operations. It goes on removing the causes of aircraft accidents caused by errors at production, assembly and maintenance of aero engines. The detail research aimed to improvement of safety was carried out for the GE Aviation Czech company in Praha. It was directed to the aero engine production at which it is necessary to observe the technological procedures and to eliminate the human factor that influences the production process. In the paper there are given results connected with the production of aero engine protective cowling, namely specifically at welding the basic components. It contains special checklist and results of safety audit.
