Safety issue description

A harness instrument, commonly issued by the Civil Aviation Safety Authority (CASA), stated that a harness could be used instead of a seatbelt for take-off and landing. Although not intended by CASA, this instrument was easily able to be misinterpreted as indicating that a seatbelt was not required to be used during take-off and landing.

Proactive action

Action number: AO-2019-025-NSA-041
Action organisation: Civil Aviation Safety Authority
Date: 01 January 2021
Action status: Monitor

In January 2021, the Civil Aviation Safety Authority (CASA) advised that regulatory provisions for use of seatbelts and other restraint devices such as safety harnesses for aerial work operations will be covered by the new Civil Aviation Safety Regulations Part 138 – Aerial work operations from 2 December 2021. CASR 138 will replace all individual harness instruments with a national standard.

Relevantly, section 14.03 of the Part 138 Manual of Standards will require that the harness is fit for the particular purpose of the operation and the crew member must have been trained in its use and assessed as competent before the flight.
