Hello everybody!!!
We encountered a problem in our t53 engine installed on our UH-1H.
This engine was removed from one helicopter to serve another one.it was working properly on the first one but experienced TEAC problems on the second one.the problem was that this engine did not top and the parameters were: At 5000 ft, N1:101.5%, OAT:15.5 deg celsius, TQ:44.8 PSI, EGT: 570.
After that flight we trimmed the FCU 1/8 of a turn CW.
The next flight parameters were: At 9000ft, OAT:4 deg celcius, N1:101.5, TQ:42 PSI, EGT:550.
Pls any suggestions for solving this problem????????
