5,670 kg to 13,608 kg (12,500 lbs to 30,000 lbs)
kilograms and 13,608 kilograms had fewer airspace
incidents in the more recent period. Airspace
incidents for helicopters increased.
For airplanes 13,608 kilograms and greater, the
number of airspace incidents classifi ed as major
remained steady from the 2003 six-month period
to the 2004 six-month period, while airspace incidents
classifi ed as minor increased. For airplanes
between 5,670 kilograms and 13,608 kilograms,
airspace incidents classifi ed both as major and as
minor decreased.

Defect incidents increased in both airplane categories
and for helicopters in the 2004 six-month
period, with helicopters showing the highest percentage
increase (Table 3, page 41). For airplanes
13,608 kilograms and greater, defect incidents classifi
ed as major and those classifi ed as minor both
increased between periods. Airplanes between 5,670
kilograms and 13,608 kilograms had fewer defect
incidents classifi ed as major and more defect incidents
classifi ed as minor in the 2004 period.

Notes
1. A moving average is an average that is recomputed
periodically in a time series by including the most
recent data and eliminating the oldest data.
2. The report said, “The actual aircraft groups used to
derive data in this report, although reported to the
nearest kilogram, have been based on the imperial
measures used in the United States design requirements,
which are the basis for the certifi cation of
most aircraft.” To group together aircraft of similar
complexity and associated operational factors, the
nominal values of 13,600 kilograms for 30,000 pounds
and 5,700 kilograms for 12,500 pounds (rather than

better represent logical dividing points, the report said.
3. An incident is defi ned by the Civil Aviation Authority
of New Zealand (CAA) as any occurrence, other than
an accident, that is associated with the operation of
an aircraft and affects or could affect the safety of
operation.
4. A critical incident is defi ned by CAA as an occurrence
or defi ciency that caused, or on its own had
the potential to cause, loss of life or limb.
5. A major incident is defi ned by CAA as an occurrence
or defi ciency involving a major system that
