The Australian Transport Safety Bureau is seeking comments from stakeholders on the proposed Transport Safety Investigation Regulations 2021 (TSI Regulations 2021) which will replace the existing Transport Safety Investigation Regulations 2003.

These regulations will clarify requirements for the reporting of transport safety occurrences for certain categories of remotely piloted aircraft, including immediate reports where there is a serious risk of harm to people or significant damage to property.

The following factsheets provide useful background information on the operational search for MH370.

ACARS

Aircraft Communications Addressing and Reporting System.

Acc Rep

Accredited representative. In accordance with Annex 13, the ATSB may assist other overseas agencies in the investigation of accidents and serious incidents that do not involve Australian registered aircraft. In these cases an ATSB investigator would be appointed to the investigation as an accredited representative. On 1 April 2014 the ATSB appointed an accredited representative to the MH370 investigation, at the request of the Malaysian Government.

The Seventh Arc

Information and analysis of satellite data and drift modelling identified an area set out in the map and labelled as the 7^th arc. At the time MH370 reached this arc, the aircraft is considered to have exhausted its fuel and to have been descending. As a result, the aircraft is unlikely to be more than 27.5 NM (51 km) to the west or 25 NM (46 km) to the east of the arc.

Based on all the independent analysis of satellite communications and aircraft performance, the total extent of the 7th arc reaches from latitude 20 degrees S to 40 degrees S.
