From the Accident
Investigation Report Summary:
The crew were operating a de Havilland Canada DHC-6 Twin Otter
aircraft in Exercise Highland Pursuit 2/97. The purpose of the
exercise, which was conducted by No. 173 Surveillance Squadron, 1st
Aviation Regiment, Australian Army, was to provide tropical
mountainous flying training in Papua New Guinea. There were three
trainees and one training pilot on board the aircraft.
On Sunday, 9 November 1997, the third day of flying operations
in Papua New Guinea, the crew were conducting a flight from Madang
and return via a number of airstrips in the central highlands. When
haze and cloud prevented them flying the flight-planned direct track
between the Koinambe and Simbai airstrips, they decided to fly
north-west via the Jimi River valley and one of its tributaries. Two
of the trainees were occupying the cockpit seats, one as flying
pilot and the other as navigating pilot using a 1:1,000,000-scale
chart. When the crew turned the aircraft to follow a tributary off
the Jimi River, the training pilot was in the aircraft cabin.
A few minutes later, their discussion regarding the progress
of the flight attracted the attention of the training pilot. By this
time, however, the position of the aircraft in the valley, and its
available performance, were such that an escape from the valley was
not possible. The aircraft collided with trees before impacting
steeply sloping ground.
It was subsequently established that when the crew turned from
the Jimi River, they entered the wrong valley. Calculations based on
the manufacturer's performance data showed that the aircraft did not
have sufficient performance to outclimb the increase in terrain
elevation from the Jimi River valley to cross the Bismarck Ranges
via this valley. There was a low level of experience and corporate
knowledge within the Army regarding the operations of fixed-wing
aircraft such as the Twin Otter in tropical mountainous areas.
Against this background, deficiencies were identified in the
planning and preparation for the exercise, including risk assessment
and the selection and briefing of the training pilot.
Recovered to Oakey - stored and striped.
