good day to everyone!
my maintenance team is having a hard time of eliminating the engine vibration warning light in our uh-id helicopters. we 've check the alignment of the engine, the mountings, by pods, tri pods and we've done all the trouble shooting procedures that can be found in the technical manuals but the problem still remain.
we have uh-1h and uh-1d. our uh-1h do not have an engine vibration analyzer but our uh-1d has.
can someone please give us an idea on how the engine vibration analyzer came into use in the uh-1d. and why does the uh-1h do not have it.
and can we ask for other opinions on how to correct the aircraft discrepancy.
by the way the engine that we are using is the 703 engines.
