Board Meeting: May 2018 Agenda Number: 12 (iii) Record No: ED18/3501 LORD HOWE ISLAND BOARD Business Paper OPEN SESSION ITEM Airport Runway Extension Feasibility Study Update RECOMMENDATION It is recommended that the Board note this report and endorse further investigation of the ‘570m runway extension’ option to the NW. BACKGROUND Lord Howe Island’s restricted runway length of 888 metres limits the type of commercial aircrafts that can operate on the Island. While other options have been considered such as leasing or hiring other aircrafts to operate on Lord Howe Island or to get other airlines to operate; without extending the runway, airlines will be restricted in the types of aircrafts that can service the Island. A sustainable and viable long-term solution is therefore needed to secure the provision of air services to Lord Howe Island. In late November 2017, AECOM Australia Pty Ltd was contracted to undertake the Lord Howe Island Airport Runway Extension Feasibility. The scope of the study includes the future aircraft requirements for the island, plane characteristics, existing runway/site limitations, CASA requirements, conceptual design, geotechnical investigation, environmental assessment, community consultation and economic impacts/costs. The project is broken down into a number of milestones. Milestone Description Anticipated time Completion of detailed assessment of extended runway and 1. March 2018 suitable aircraft options 2. Completion of preliminary geotechnical investigation June 2018 3. Completion of conceptual engineering design August 2018 4. Completion of preliminary environmental assessment September 2018 5. Undertake economical assessment and preliminary business case October 2018 6. Final presentation and report December 2018 The funding for the project comes predominately from a Restart NSW grant through Infrastructure NSW with a small amount of Board staff wages for project management as shown below: 1. Infrastructure NSW - Restart NSW funding $450,000 2. Board staff wages $ 19,000 TOTAL $469,000 (excl. GST) Page 1 of 3 CURRENT POSITION AECOM visited the island in December 2017 to undertake their inception meeting, various site inspections and to gather additional background reports of works previously undertaken by the Board. AECOM have been in consultation with various airline operators in Australia to understand their current and future plans in respect to aircraft type and operations. AECOM have also consulted with airline manufacturers, CASA and Airservices Australia in order to complete the attached report for the milestone 1 requirements of this project. AECOM’s “Detailed Assessment of Extended Runway Requirements and Suitable Aircraft Report” provides a detailed review of the runway requirements for operation of the existing DHC8- 200 regular passenger transport (RPT) aircraft at Lord Howe Island Airport (LDH), and the requirements for alternative aircraft types such as the DHC8-300/400, ATR42/72 and Fokker 50. In addition future aircraft design trends were investigated, including electric aircraft. It was concluded that electric aircraft of comparable size will be developed within the next 15-20 years but at this point no conclusions can be drawn on their runway requirements except that they are expected to be similar to current aircraft. The predominant western-designed and in production turbo-prop aircraft in the 30-70 seat class is the ATR42 (48 seats), ATR72 (68 seats) and the Bombardier DHC-400 with 74 seats. These aircraft are the preferred choice of the “mainline” airlines such as Qantas and Virgin Australia. Older types no longer in production such as the DHC8-200/300, the Saab 340 and Fokker 50, while capable aircraft, are confined to the small regional airlines such as Rex and Skytrans. The following runway options were investigated during this study: • Option 1: Do Nothing. • Option 2: 450m runway extension. • Option 3: 570m runway extension. • Alternative Option 1: Runway realignment. • Alternative Option 2: Leasing or purchasing of aircraft. It is proposed the current runway orientation should be retained due to the likely considerable cost associated with a full realignment and is not recommended for further study. A ‘Do’ Nothing’ approach could leave the island with no RPT service from March 2022 onwards once the current agreement with Qantas expires; this is not considered a viable solution. Although a 450m extension option provides for the future operation of some candidate aircraft, it does not provide sufficient “future proofing” for efficient operation of the ATR72 and DHC8- 400 and therefore the recommendation is to further investigate a 570m extension option. Conclusion The recommendation of the review is to further investigate the ‘570m runway extension’ option to the NW. Pending the outcome of the ‘570m runway extension’ feasibility study, leasing or purchasing of aircraft could be investigated although the significant operational, logistical and legal aspects would need to be considered in further detail.
