Executive summary
When landing at Queenstown aerodrome insufficient braking was achieved. The aircraft was steered to avoid obstructions and rolled through the aerodrome boundary fence, across a 750 mm deep ditch to come to rest 96.7 m from the runway end. One passenger subsequently reported a minor neck injury. No fault was found with the with aircraft braking system. Safety recommendations covered hazardous structures on the extended runway centreline, location of remote reading of wind conditions at either end of the runway, friction measurement of runway surfaces, and approach and landing procedures.
Related Recommendations
Ensure that the pilot not flying has a responsibility during any approach to land to monitor the aircraft's speed, height, distance to go and configuration of air brakes and spoilers to advise the pilot flying if any of these factors are not within the limits.
Ensure that a standard approach path monitoring technique is prescribed, taught and adhered to.
Revise immediately, the information in the NZAIP Planning Manual page AGA 0-29 Section 9 and in Civil Aviation Information Circulars GEN A19 and A20.
Review the appropriateness of the company operations manual landing procedure which requires a deviation from the PAPI glide path indication to achieve the required touchdown point versus the manufacturer's claim that the necessary landing distance safety margins can be achieved by maintaining the standard approach technique.
Ensure that the pilot who will do the landing takes over in sufficient time to accustom himself to the prevailing conditions.
Research the most appropriate location for the sensors for a system of remote reading anemometer to provide an accurate comparison of wind conditions at either end of runway 05/23 and install such a system as soon as practicable.
Implement a credible system of Mu-meter monitoring on a regular basis, of runway surfaces at all aerodromes used for air transport operations and with a runway length of 1200 metres or more as per ICAO recommendation in Annex 14 to the Convention on International Civil Aviation paragraph 2.6.1 or otherwise.
Remove the present substantial concrete gate posts on the extended centre line of runway 05 and replace them with a light weight frangible structure to reduce the hazard to overrunning aircraft.
