Proactive Action

Action number: AO-2015-046-NSA-008
Action organisation: Virgin Australia/Virgin Australia International
Date: 18 September 2018
Action status: Monitor

In response to a preliminary analysis of this incident, Virgin Australia/Virgin Australia International conducted an initial post-implementation review of the change to their policy that permitted a damp runway to be considered dry for performance purposes. A further review of this change is currently underway in response to the ATSB’s investigation report. This review is examining change objectives, proposed and realised risk profile, current regulatory direction and industry guidance, and operational outcomes from the policy change. Findings from this review will be used by Virgin Australia/Virgin Australia International to determine whether further changes to the aircraft performance policy are required. Any policy changes will be incorporated into the aircraft performance training course.
