Aircraft and crew

P2-PXE, the aircraft involved in the accident, in 2014.

The accident aircraft was a Boeing 737-8BK, registration P2-PXE, msn 33024, Boeing line number 1688. It had first flown on 1 April 2005.[2] At the time of the accident the aircraft had accumulated 37,160 hours and 36 minutes flight time in 14,788 cycles.[3]

The aircraft was originally registered VT-AXC for Air India Express and was delivered on 19 April 2005.[2] On 6 July 2005, it was damaged in a runway excursion on landing at Cochin International Airport, India.[4] On 29 July 2010, the aircraft was sold to Jet Airways and was registered VT-JBT. It was sold to CIT Leasing Corporation on 24 July 2013 and registered M-ABGK before being sold to Loftleidir, which leased the aircraft to Air Niugini on 13 September 2013. The aircraft was registered P2-PXE.[2][3] On 12 May 2018, it was struck by Lockheed L-100 Hercules N403LC of Lynden Air Cargo whilst parked at Port Moresby Airport, sustaining damage to its right winglet.[5]

The captain and pilot in command was a 52-year-old Papua New Guinean male who had 19,780 flight hours, including 2,276 hours on the Boeing 737.[3]^:7 The first officer was a 35-year-old Australian male who had 4,618 flight hours, with 368 of them on the Boeing 737. An engineer from Loftleidir was also on board and was sitting in the cockpit jumpseat. He was filming the landing for recreation purposes using his cell phone. The phone survived the accident and the video was used for the subsequent investigation.[3]^:2

Accident

The aircraft was operating an internationally scheduled passenger flight from Pohnpei Airport, FSM to Port Moresby Airport, Papua New Guinea via Chuuk International Airport, FSM. At 10:10 local time (00:10 UTC), the aircraft landed in the Chuuk lagoon 135 metres (443 ft; 148 yd) short of Chuuk International Airport. Initial reports stated that all twelve crew and 35 passengers were rescued by local boats and United States Navy personnel.[2][6] However, the body of one male passenger was later found by rescue divers searching the accident site. Air Niugini stated that the deceased passenger had been seen by other passengers, evacuating the aircraft.[7] Nine people were taken to hospital.[8][9] The preliminary report into the accident states that the body of the deceased passenger was recovered from the aircraft.[10] Six people were seriously injured.[10] Some of the injured sustained broken bones. It was reported that there were thunderstorms in the vicinity of the airport at the time of the accident.[11] The aircraft subsequently sank in 30 metres (100 ft) of water.[6]

Investigation

The Papua New Guinea Accident Investigation Commission opened an investigation into the accident.[12]

The Department of Transportation, Communications & Infrastructure in the Federated States of Micronesia opened an investigation. A preliminary report was issued on October 26.[10]

On July 18, 2019, the Papua New Guinea Accident Investigation Commission issued its final report: the flight crew did not comply with Air Niugini Standard Operating Procedures, nor the approach or pre-landing checklists, and did not adequately brief the approach. The flight path became unstable after autopilot disconnect. The Precision Approach Path Indicator was showing three white lights just before entering Instrument Meteorological Conditions (IMC). The rate of descent significantly exceeded 1,000 feet/min in IMC. The glideslope deviated from half dot low to two dots high within nine seconds after passing the Minimum Descent Altitude. The flight crew heard, but disregarded, thirteen Enhanced Ground Proximity Warning System (EGPWS) aural alerts (Glideslope and Sink Rate) and flew a 4.5° average glideslope. EGPWS showed a visual PULL UP warning on the Primary Flight Display. The pilots lost situational awareness. The approach was unstabilised, but the captain did not execute a missed approach. The copilot was ineffective and oblivious to the rapidly unfolding unsafe situation. A continuous WHOOP WHOOP PULL UP aural warning could have been effective in alerting the crew of the imminent danger.[3]
