Authorities have confirmed that key parts of the wreckage will be flown outside the country for advanced forensic examination as investigators seek clear answers on what caused the fatal accident.
The helicopter, identified as an Airbus H125 model, went down in Mosop area, Nandi County, killing all six people on board.
Among those who lost their lives were the pilot and members of the MP’s team.
The crash shocked the nation and left many Kenyans demanding transparency in the investigation.
Officials from the Aircraft Accident Investigation Department have already secured the crash site and collected critical components from the aircraft.
According to preliminary information, some of the most sensitive parts, including flight control systems and engine components, cannot be fully analyzed locally.
For that reason, they will be transported to specialized laboratories abroad where experts have more advanced tools to examine them.
Investigators believe that examining the wreckage outside the country will help determine whether the crash was caused by mechanical failure, weather conditions, or human error.
Early reports suggested that poor visibility and bad weather may have played a role, but authorities insist that no conclusion has been reached.
The decision to involve foreign experts follows international aviation standards. Under global safety rules, aircraft accident investigations must be thorough, independent, and guided by technical evidence.
Aviation experts say sending parts abroad is common practice, especially when dealing with complex aircraft systems.
Meanwhile, leaders across the political divide have continued to mourn MP Ngeno, describing him as a dedicated public servant. Residents from his constituency have also called for a transparent investigation to ensure the truth comes out.
A preliminary report is expected within the next few weeks. However, a full investigation could take several months before a final report is released.
