The awareness and communication of runway works is an ongoing issue for both aerodromes and airline operators.
The group also raised aerodrome works for Part 121 of CASR operators- Issue – complex and changing aerodrome environment – works.
What can Aerodrome and Airlines operators do?
Part 139 MOS Chapter 15 identifies that it is the aerodrome operator’s responsibility that aerodrome works do not create a hazard to aircraft or cause confusion to pilots. The Method of Working Plans (MOWP) sets out these arrangements and is a way to meet management of change with SMS needs. Early engagement with operational stakeholders and CASA for runway projects will prioritise safety and help to support successful outcomes.
Aerodrome operators should have established points of contacts for providing MOWPs including:
- airlines who operate to the aerodrome
- third party contractors such as ground handlers
- refuellers
- catering provider
- Air Services including ARFF.
They should consider stakeholders using the aerodrome at night when works are occurring, for example emergency services or instrument flight procedure designers.
Maintaining contact through regular meetings enables impacted parties to address any:
- emerging safety issues
- aerodrome access
- changes to the works schedule or procedure.
This will make sure there is a common understanding of the work plan. Considering the impact of the change for multiple stakeholders will make sure the risk assessments and treatments are in the risk management plans. One way to achieve this is through the local runway safety teams. Depending on the complexity of the project separate meetings may be more appropriate.
Airline operators raised difficulties in identifying relevant hazard information regarding works within the MOWP. Part 139 MOS Section 16 – Method of Work Plans outlines the information required. This includes a section for restrictions to aircraft operations. The differences in presentation of relevant data within the MOWP can also create confusion for airlines.
Through the runway safety meetings, airline operators can provide feedback on the MOWPs and presentation of the information. They can also report issues inhibiting their ability to extract critical information.
The airline operator also has a requirement to ensure their flight crew have the necessary information regarding special procedures in use at the aerodrome. This includes NOTAMS and company operational notices. The PIC is ultimately the one required to ensure the landing area is suitable.
Operators should encourage the use of their safety reporting if airline or aerodrome staff identify any hazards or risks during runway works. MOWPs should be in place to address these as soon as possible.
Aerodrome works was also raised at the SSRP for CASR Part 121 operators- Issue – complex and changing aerodrome environment – works.
What are we doing and already delivered?
CASR Part 139 MOS
We have updated CASR Part 139 MOS to include requirements for aerodrome operators on:
- conducting aerodrome works
- developing method of working plans (MOWP).
Chapter 15 of the MOS requires aerodrome operators to ensure that work does not pose hazards to aircraft or confuse pilots.
The MOS also requires the MOWP to communicate relevant information clearly and document it separately.
ICAO through the Global Runway Safety Action Plan (GRASP) urges States to maintain efforts for reducing runway safety occurrences. The establishment of Local Runway Safety Teams are a good way to reduce runway accidents.
Advisory circulars
Our AC 139.C-22 v1.0 Runway Safety Teams provides guidance to aerodrome operators in implementing local runway safety teams. CASA is drafting additional support for aerodrome works, including MOWP publication.
We have also issued the following ACs that assist operators with their management of runway works:
- AC 91-02 – Guidelines for aeroplanes with MTOW not exceeding 5 700 kg - suitable places to take off and land
- AC 139.C-27 - Risk management plans for aerodromes
National Runway Safety Group
CASA chairs the National Runway Safety Group. This is a hazard specific working group that facilitates state-level visibility and continuous improvement in runway safety performance. It brings together industry stakeholders, including representatives from LRST, that have a common goal in enhancing runway safety.
As required, the NRSG can establish supporting subcommittees to review specific incidents and the effectiveness of controls from a national perspective. This has recently included a Displaced Thresholds and Runway Working Group. One of the items currently in progress from this working group is updating Advisory Circular 139.C-15 Safe planning and conduct of aerodrome works.
