## Chapter 2 Overview of Current Air Traffic Safety Measures

## 1 Ensuring Safe Operation of Aircraft

## Promotion of Preventive Safety Measures

In order to prevent the occurrence of accidents, data regarding accidents, major incidents, equipment defects, human error, etc. are collected and analyzed, and deliberation/examination is held in meeting of experts regarding countermeasures necessary for improving safety. Information related to air transport safety is then compiled and widely released. In April 2009, safety trouble information and test/audit records were managed centrally, a system shared by authorized individuals began its operation, and preventive safety measures are being promoted.

## Safety Measures towards Air Carriers etc

Important check points were decided for every airline company, and along with frequently implementing technical and moreover systematical inspection of premises from a full-time examination structure, effective safety audits were implemented for airline companies such as expeditious premise inspections in cases of occurrence of trouble involving safety had occurred.

Based on the “Transport Safety Management System” introduced in October 2006, a safety management system was established by the operators which was taken action by management executives to on-the-site workers as a whole. The country carried out the evaluation for transport safety management to 62 companies by the end of December 2009 to confirm the status of implementation.
