What happened
The aircraft, identified as the Challenger, was initially required to abort its first approach to land at Lumbo. The specific reason for this aborted maneuver is not documented in the available records. During the subsequent second landing attempt, the seaplane struck the water surface and came to rest near Ilha de Moçambique Island. The impact was severe enough that the cockpit section detached from the main fuselage.
Findings
The accident resulted in significant loss of life and injury. Two crew members lost their lives, while the four other individuals on board sustained injuries. While the exact technical or operational cause of the initial aborted landing remains unknown, the structural failure during the second impact was catastrophic.
