The Agusta Westland AW 119 MKII helicopter type registration 5Y-NPW operated by the National Police Service Air Wing (NPSAW) departed Wilson Airport for a Visual Flight Rules (VFR) flight to Badan Arero in Marsabit via Embu and Wajir with three occupants.
The aircraft made a precautionary landing four miles west of the Ndula marker due to bad weather, but took off again when the weather conditions improved and landed at Embu where three more passengers embarked. The helicopter then took off for Isiolo to refuel before flying to Badan Arero. However, while enroute to Isiolo, the weather conditions deteriorated below VFR minima, prompting the crew to initiate a precautionary landing.
The helicopter collided with trees in fog while attempting to land.
The two pilots and the four passengers were extricated from the wreckage; two with serious injuries and four with minor injuries of varying degree. There was no pre or post impact fire, but the helicopter was damaged after colliding with trees and terrain.

The investigation identified the probable cause of the accident as the pilot‟s lack of situational awareness, and the decision to continue the flight into deteriorating weather conditions that occasioned spatial disorientation after inadvertent entry into instrument meteorological conditions and subsequent loss of helicopter control.

The investigation further established that the NPSAW Standard Operating Procedures did not provide guidance in a number of areas, which contributed to poor decision-making and coordination.
