The incident went unreported and came to light only through passengers reporting on social media, that the right hand propeller had stopped in flight and later on restarted with their flight landing in Beira. Those passenger reports eventually reached Mozambique's Ministry of Transport several weeks later, who in turn initiated a safety review of LAM and Mocambique Expresso by Mozambique's DGCA.
Sources told The Aviation Herald, that lack of system knowledge caused the incident. FADEC would automatically limit the revolutions per minute (RPM) to the permitted maximum 1020 revolutions per minute even if the power lever is moved beyond the MAX detent, a propeller overspeed did not occur. Control of the engine is regained by moving the lever back into the MAX detent and then to the desired setting.
On Mar 4th 2016 LAM's safety pilot told The Aviation Herald: "I confirm that we had a 'Overspeed indication light' on that flight, and that the crew followed the appropriate checklist." The event is still under internal investigation, no conclusions have yet been reached.
