Rail Standards for New Trains The National Rail System Standards (6) (Engineering and Interoperability) is the only standard within the National Rail System set that defines braking performance. However, it does not address the performance in low adhesion conditions of modern metropolitan passenger trains that are fitted with computer controlled brake and wheel slide protection systems. The current National Rail System Standard (6) does not require any more from a braking system than for a train to be able to stop within a specified distance in dry conditions.

Require companies engaged in aerial work activities to demonstrate their capability in a different sample of their specialist tasks during consecutive audit inspections.

Reviews the LTS101 engine periodic inspection requirements regarding the GP turbine rotor shroud sealing rings to establish if there is a need for these sealing rings to be replaced or measured as part of the scheduled maintenance.

Institute a requirement in the Certificate of Airworthiness inspection of refurbished aircraft that all flight instruments shall have been overhauled or are within their approved "shelf" life if the aircraft has not been operated for a significant period before the refurbishing was completed.

Until more effective protection for the public is provided at the Heretaunga Street pedestrian level crossing area in Hastings they restrict the speed of trains in that area to 40 km/h.

Conduct a cost/benefit analysis of the establishment of an automated monitoring system of the beacon lights in selected critical areas, such as major bends in the channel, of Otago Harbour, and if feasible establish a monitoring system.

The present voluntary and informal nature of aerodrome user groups restricts their potential for improving operational safety at aerodromes.

Give priority to developing a suitable solid wheel option to replace tyred wheels on Electric Multiple units.

The medical examiner did not, and saw no reason to, contact the instructor's GP as part of the medical assessment process. Had he done so, it is likely that he would have learned of the instructor's recent illness and initiated a more formalised review of the instructor's fitness to fly. A procedural requirement for medical examiners to consult GPs would help to ensure that they are fully informed about applicants' health. On 28 June 2017 the Commission recommended to the Director of Civil Aviation that he review the medical application process:
