Papua New Guinea is a signatory to the Convention on International Civil Aviation (Chicago Convention) 1947, which established principles and arrangements for safe and secure international civil aviation. The International Civil Aviation Organisation (ICAO), which administers the Chicago Convention, undertakes safety and security audits of signatory states to measure compliance with, and application of, standards and recommended practices. A safety audit was undertaken for PNG in 2009, and as a result, the government, through CASA PNG, is pursuing a compliance action plan accepted by ICAO to address safety and security issues.

The Civil Aviation Act and subsidiary regulations and rules provide the legal framework for ensuring that safety principles and practices are followed. These provide certification requirements for aircraft, aircrew and other defined occupations in the civil aviation industry. The government will require that the legislation is rigorously implemented, monitored, and reported and will require CASA PNG, NAC and PNGASL to make passenger safety its priority.
