In support of efforts to finalise this investigation, technical information and advice has been sought from the overseas manufacturer of the aircraft’s flight director equipment. This information and advice is anticipated in mid-March 2017. This has affected completion of the draft investigation report, which is now anticipated in May 2017.

The ATSB regrets the delay in the finalisation of the investigation and report. The ATSB has identified a number of occurrences of Enhanced Ground Proximity Warning System (EGPWS) alerts during approaches to runway 30 at Adelaide Airport. These occurrences took place in approximately the same position as the EGPWS occurrence involving VH‑TQM. Accordingly, the scope of this investigation has been increased to include an examination of the:

  • survey of obstacles on the approach path to runway 30
  • construction of the approach procedures for runway 30
  • EGPWS database for the approach path to runway 30.

The draft report is anticipated for release to directly involved parties (DIP) for comment in February 2017. Feedback from those parties over the 28-day DIP period on the factual accuracy of the draft report will be considered for inclusion in the final report anticipated to be released to the public in April 2017.

Completion of the draft investigation report has been delayed due to workload and competing priorities. The draft report is anticipated for release to directly involved parties (DIP) for comment in March 2016. Feedback from those parties over the 28-day DIP period on the factual accuracy of the draft report will be considered for inclusion in the final report, which is anticipated to be released to the public in May 2016.

 

___________

The ATSB has commenced an investigation into aircraft control issues involving a Bombardier DHC-8, VH-TQM, near Adelaide Airport, South Australia on 24 April 2015.

During approach to runway 30 in instrument meteorological conditions, the airspeed reduced below the optimal approach speed and the crew adjusted the power to regain airspeed. The flight director failed during the approach. The crew received two ground proximity warnings.

As part of the investigation, the ATSB will interview the flight crew, obtain flight and air traffic surveillance data and gather additional information.

A report will be released within several months.
