Good evening house. Our C130H aircraft returned back today from an FCF after an unsuccessful air start. NTS check was successful and the engine feathered with a cruise engine shutdown procedure. However, when on airstart following the stated procedures, the airstart went well until 60% RPM when all engine parameters wound down to zero and consequently prompted an immediate feather. A restart was attempted on the ground and was successful. We have consulted our troubleshooting manuals but found nothing so if anyone has a suggestion to correct this problem would be appreciated.

During the generator ops check, the book tells you to sequentially turn on/off the generators to tell you if the generator can handle the load of the aircraft. When generator 2,3,4 are off generator #1 shows high voltage on phase B only (121 volts). Along with that, we are getting ECBU's 6,7,8 input failures. We have changed GCU, engine generator and swapped BIU's. We still are getting the same problem. Any input will help. Thanks in advance

Hey guys My topic is a follow on of this discussion. Over the last several months we have had a large number of TD related problems. Some have been fixed by the usual TD am or valve change, or just a careful yellow box. Many have either been sent to me in the test cell, or I have spotted enough of a disparity to warrent further investigation. The most common failing is a high take off TIT in AUTO, with a lean fuel control. I like to set SLOPE and NORMAL at 1075°C and take things from there. As long as TIT doesnt exceed 1083°C we're good to go. Normally a new amp or a bit of careful tweeking of the NULL orifice and the CIT can b…
