Footage taken moments before Air Niugini Flight 73 crashed into the waters of Chuuk has been released by the Papua New Guinea Accident Investigation Commission.
The footage was captured through a smartphone used by the jump seat occupant. It shows what transpired in the cockpit prior to the Boeing 737 plummeting into the lagoon falling short of the Chuuk international airport on Sept. 28, 2018.
There were 12 crew members and 35 passengers on board when the Boeing 737 crashed-landed into the lagoon 1,500 feet from the landing strip.
As a result of the crash, six passengers were seriously injured and one passenger died. The aircraft sank 90 feet to the bottom of the lagoon.
The final report into the crash revealed that the flight crew did not comply with Air Niugini standard operating procedures, blaming the pilots for disregarding alerts that they had passed the minimum descent altitude at 397 feet and the impact point 19 seconds before hitting the water.
The report states that the flight was “not at a standard that would promote safe aircraft operations” and that the aircraft’s flight path became unstable with lateral over-controlling commencing shortly after autopilot disconnect at 625 feet.
From 546 feet, the aircraft was flown in instrument meteorological conditions and the rate of descent significant exceeded the 1,000 feet minimum in IMC from 420 feet.
The report also states that both pilots were not situationally aware and did not recognize the developing significant unsafe conditions during the approach after passing the missed approach point when the aircraft entered a storm cell and heavy rain.
The report states that the pilots initiated the approach at an “excessively high rate of descent, resulting in the aircraft continuing descent below the glide scope and impacting the water 1,500 feet short of the runway.”
The report concluded that NTSB staff disagrees that an additional warning would have been effective in alerting the crew. “NTSB staff believes that the actions of the pilots to disregard the 16 EGPWS alerts and to not comply with Air Niugini policy clearly demonstrate that the crew was unresponsive to guidance that should have prompted a clear and decisive action to initiate a missed approach.”
