A twin-engine maritime patrol aircraft struck a hill near Niton, Isle of Wight, during low-level flight in foggy conditions, resulting in three fatalities and one serious injury.

What happened

The crew was conducting a maritime patrol mission along the south coast of England when the incident occurred. The aircraft was flying at a low altitude under poor visibility conditions caused by fog. During this phase of flight, the twin-engine machine collided with a hill situated in Saint Catherine's Down, north of Niton on the Isle of Wight.

The impact resulted in significant casualties among the four occupants. Three crew members were killed in the accident, while one other individual sustained serious injuries. The aircraft belonged to the 48th Squadron, and the flight was part of routine operational duties along the coastline.

Findings

The official investigation determined that the primary cause of the accident was a controlled flight into terrain. This conclusion highlights the critical risk associated with low-level flying in reduced visibility environments, where spatial disorientation or loss of situational awareness can lead to inadvertent ground contact.

Probable cause

Controlled flight into terrain due to poor visibility and low altitude operations.
