Investigation Summary
The flight was part of a vital civil aviation link between the northern Jaffna Peninsula and the capital, Colombo, during the Sri Lankan Civil War. Prior to the shootdown, Lionair had received a warning letter from the Tamil Eelam Administrative Service demanding that the airline cease transporting Sri Lankan Armed Forces personnel. The letter warned that failure to comply would result in an attack after September 14, 1998. Consequently, Lionair had closed its Jaffna office just four days before the disaster. On the day of the accident, the aircraft departed at 13:40 local time. While climbing toward flight level 140, the crew reported depressurization, a symptom consistent with a missile strike compromising the fuselage. Shortly after this report, the aircraft disappeared from radar and plunged into the Gulf of Mannar. The investigation was stalled for over a decade due to the ongoing conflict and the location of the wreckage in rebel-controlled waters. In 2012, a former LTTE member arrested by the Terrorist Investigation Department confessed that the aircraft was targeted on the orders of Poththu Amman, a senior LTTE leader. The Sri Lankan Navy eventually salvaged approximately 30% to 40% of the wreckage in 2013. While the formal CAASL excavation report noted that no human remains were found during that specific phase, earlier salvage efforts and local media reports confirmed that clothing and remains belonging to approximately 22 victims were recovered and put on display for identification in January 2014. Additionally, a single decomposed skeleton wearing a life jacket was recovered separately from the main wreckage site.
Final Conclusions
The investigation by the Civil Aviation Authority of Sri Lanka (CAASL) concluded that the aircraft was destroyed by unlawful interference. The primary evidence for the missile strike was the confession of an LTTE cadre who admitted to firing the weapon from Iranaitivu Island, supported by the subsequent recovery of wreckage in that specific area. Although a highly corroded component identified as an auxiliary data recorder was eventually found, no functional data was recovered from it, and no traces of the primary flight data or cockpit voice recorders were ever located.
