OK we began chatting in the other post about the Griffon accident and the subject turned to maintenance differences between the military and commercial operators, then today I noticed one of our aircraft sitting there for an engine change.
The boys began yesterday (Monday), today the new engine was installed around 10:30. So we are talking about 24 hours to get one engine out and the other engine in. Now the new engine does have to be rigged with the intake fairing and starter which come off the old one before it can go up there. The aircraft won't actually be ready for test flight for this engine change until late tomorrow (Wednesday). So we are talking about changing at T58 on an S61 in around two and half days with three to four guys working together, two shifts per day!? :wacko:
How would that compare? Any of you wrenches out there work on S61s and can comment??? What would be an expected kind of norm for commercial operations? :unsure:
By comparrison when we were deployed at sea, our techs (three guys) changed one of our engines twice in the same day (long story and yes we had two spares) and both were test flown, so it can be done.
