Safety issue

N/A

Number

AO-2015-089-SAN-014

Organisation

Mustering and amateur-built helicopter industry

Safety advisory notice

Operating a helicopter within the stated design intent and limitations is essential for safe conduct of flight. The ATSB advises owners/operators of amateur-built experimental aircraft to be fully aware of the risks associated with this category of aircraft and that operation outside the limitations prescribed by the manufacturer, such as the addition of unapproved modifications and use for mustering operations, can produce unexpected stresses on the airframe leading to premature failure of components.

Safety issue

Upper torso restraints (UTRs) were not required for all passenger seats for small aeroplanes manufactured before December 1986 and helicopters manufactured before September 1992, including for passenger transport operations. Although options for retrofitting UTRs are available for many models of small aircraft, many of these aircraft manufactured before the applicable dates that are being used for passenger transport have not yet been retrofitted.

Commercial Balloon Operators

Safety advisory notice

The ATSB advices all commercial balloon operators utilising vehicle-assisted deflation methods to review their current operational practices in light of the findings in the ATSB investigation report AO-2019-014 with the aim of mitigating the risks associated with the procedure. This review should be conducted with emphasis on:   reducing the risks associated with a communications breakdown between the pilot and vehicle driver, and   include a review of the positioning of occupants within the basket to minimise the likelihood of injury if the basket tips during the vehicle assisted deflation.
