From the report:
"
At 2140:50, a yellow caution light illuminated and a crew alert system (CAS) message appeared on the display. Occupied with the recovery procedure, the pilot flew solely through the outside picture and the attitude indicator. The aircraft descended to a height of 31 ft AGL before attaining a positive rate of climb. As the pilot’s recovery manoeuvre ceased and control inputs returned to normal, the warning self-extinguished at 2140:57. The pilot noticed the warning, but could not read it before it extinguished.""A crew debrief took place and it was thought that a main gearbox overtorque could have occurred. There is no capacity in the aircraft for the crew to check for overtorque without the presence of an aircraft maintenance engineer (engineer). As a precaution, and as per Operations Manual requirements, the crew called a duty engineer to explain the situation and seek advice.
The duty engineer asked the crew to check the CAS system for messages. If an overtorque occurred, a white status message saying ‘maintenance’ would be present. This would signal a requirement to download and analyse data from the aircraft’s central maintenance computer (CMC).
The pilot estimated the extent of a potential overtorque to be within operational limits. The crew did not detect a maintenance message. With this information, the duty engineer advised that no maintenance activity was required."
Does the 139 have aural and/or visual alerts for low NR and overtorque (this one still lit after touchdown)?
