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 {{convert|135|m|ft yd|abbr=}} short of Chuuk International Airport. Initial reports stated that all 12 crew and 35 passengers were rescued by local boats and United States Navy personnel.{{cite web |url=https://www.c7f.navy.mil/Media/News/Display/Article/1647405/us-navy-uct-2-renders-assistance-following-plane-crash-in-chuuk/ |title=U.S. Navy UCT 2 Renders Assistance Following Plane Crash in Chuuk |first=Matthew R. |last=White |publisher=United States Navy 7th Fleet |access-date=28 September 2018}} However, a male Indonesian passenger was reported missing after the evacuation. Three days of searching failed to locate the missing passenger seated at 23A, and the investigating commission requested a verification search of the airplane. On 1 October 2018, Japanese divers located the passenger between partially submerged seat rows 22 and 23, in the vicinity of a fuselage fracture; he had not been wearing a seatbelt.{{cite news |title=Pilots ignored alerts in fatal Air Niugini flight 73 crash, report finds |url=https://www.abc.net.au/news/2019-07-18/air-niugini-crash-flight-73-pilots-ignored-alerts/11322486 |access-date=16 November 2022 |work=ABC News |date=18 July 2019 |language=en-AU}} Air Niugini had previously stated that the deceased passenger had been seen by other passengers evacuating the aircraft.{{cite news |title=Air Niugini plane crash turns fatal after divers find missing passenger's body |url=http://www.abc.net.au/news/2018-10-02/passengers-body-found-after-air-niugini-plane-crash/10327378 |accessdate=2 October 2018 |work=ABC News |date=2 October 2018}} Nine people were taken to hospital.{{cite news |title=Air Niugini Says All on Board Rescued After 737 Lands in Chuuk Lagoon |url=http://australianaviation.com.au/2018/09/air-niugini-says-all-on-board-rescued-after-737-lands-in-chuuk-lagoon/ |publisher=Australian Aviation |accessdate=28 September 2018 |date=28 September 2018}}{{cite web|url=https://www.smh.com.au/world/oceania/png-bound-air-niugini-flight-lands-in-ocean-20180928-p506n0.html|title=PNG-bound Air Niugini flight lands in lagoon|first=Josh|last=Dye|date=28 September 2018|website=The Sydney Morning Herald|accessdate=28 September 2018}} Six passengers were seriously injured.

The Papua New Guinea Accident Investigation Commission opened an investigation into the accident.{{cite web |url=https://www.reuters.com/article/us-micronesia-crash/passengers-safe-after-air-niugini-flight-crashes-into-sea-in-micronesia-idUSKCN1M807G |title=Passengers safe after Air Niugini flight crashes into sea in Micronesia |publisher=Reuters |date=28 September 2018 |accessdate=29 September 2018}} The Micronesian government delegated the investigation to the Papua New Guinea government on 14 February.{{cite web|url=https://www.aic.gov.pg/sites/default/files/2020-08/FINAL%20REPORT%2C%20issued%2015.07.2019.pdf|title=Final Report AIC 18-1004|publisher=Papua New Guinea Accident Investigation Commission|access-date=2025-01-02|page=PDF p. 3/116}}

The Department of Transportation, Communications & Infrastructure in the Federated States of Micronesia issued a preliminary report on 26 October.{{cite web |url=http://www.aic.gov.pg/pdf/PreRpts/TC&I%2018-1001%20%28AIC%2018-1004%20P2-PXE%29.pdf |title=Preliminary Report 18-1001 |publisher=Department of Transportation, Communications & Infrastructure |accessdate=26 October 2018 |archive-url=https://web.archive.org/web/20181026222354/http://www.aic.gov.pg/pdf/PreRpts/TC%26I%2018-1001%20%28AIC%2018-1004%20P2-PXE%29.pdf |archive-date=October 26, 2018 |url-status=dead }} It stated that the body of the deceased passenger was recovered from the aircraft. Pathological analysis found that the passenger had succumbed to injuries within three minutes of impact. An autopsy determined that there was a lack of trauma around the waist and hips, indicating that the passenger "was not wearing a seat-belt" at the time of the crash, "which allowed his body to become a projectile sustaining traumatic head and facial injuries".{{Cite web|date=2019-07-20|title=Sole fatality in Air Niugini crash attributed to seat-belt avoidance|url=https://en.dailypakistan.com.pk/world/sole-fatality-in-air-niugini-crash-attributed-to-seat-belt-avoidance/|access-date=2021-08-06|website=Daily Pakistan Global|language=en}}

On 18 July 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 {{convert|1,000|ft/min|m/s}} 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 unstabilized, but the captain did not execute a missed approach. The copilot was ineffective and oblivious to the rapidly unfolding unsafe situation. The continuous alarm WHOOP WHOOP PULL UP aural warning could have been effective in alerting the crew of the imminent danger.{{cite web |url=https://aic.gov.pg/sites/default/files/2020-08/FINAL%20REPORT,%20issued%2015.07.2019.pdf |title=Final Report AiC 18-004 |publisher=Papua New Guinea Accident Investigation Commission |accessdate=15 March 2022}}

The final report stated confusion led to a botched evacuation of the airplane. According to cabin crew members, the word 'evacuate' was not understood by some of the passengers. Several passengers took their cabin baggage with them against instructions. However some cabin crew members acted with conspicuous courage, retrieving passengers lying underwater in the aisle or still strapped in their seats. The report concluded the Papua New Guinea Civil Aviation Safety Authority "did not meet the high standard of evidence-based assessment required for safety assurance, resulting in numerous deficiencies and errors".{{Cite web|date=2019-07-19|title=Pilots blamed and botched rescue exposed in report into Chuuk plane crash|url=https://www.independent.co.uk/travel/news-and-advice/air-niugini-crash-chuuk-boeing-737-fatal-plane-pilots-blamed-a9011881.html |archive-url=https://web.archive.org/web/20190719115941/https://www.independent.co.uk/travel/news-and-advice/air-niugini-crash-chuuk-boeing-737-fatal-plane-pilots-blamed-a9011881.html |archive-date=2019-07-19 |url-access=limited |url-status=live|access-date=2021-08-06|website=The Independent|language=en}}
