On time and on budget, the airplane was returned to service, and we took off from Tampa, Florida, for Delaware on our first flight. The left engine started just like it used to, hotter than the right one. At altitude, the left engine burned a little hotter than the right one — just like it used to. It also burned slightly more fuel. I did not conclude from these measurements that I had erred in getting a hot section. I chose a different take-home message: I came away with renewed and profound respect for the turbine engine and the PT6 in particular. It is said that, if you can start them, they will not fail. This is a little disingenuous because PT6s can provide excitement (very infrequently), but it is rarely the engine itself that fails. Rather some item bolted to the engine, like a fuel control unit or starter generator, causes the trouble.
