Yesterday I felt pretty bad with a really sore throat. In spite of that, I had to go to the hangar for a short while to cancel a mechanic oral and practical exam that was scheduled for today. I grabbed the camera as I left the house, thinking I may get a shot of the final engine runs after the plane's inspection.
Tim is on the ladder peering into the nose of the plane through an open panel, monitoring the a/c system. The a/c compressor is on the right engine, so the left engine was not needed for this check.
On the ground by the left engine is equipment for doing a compressor wash. Washing the engine compressor section restores engine performance. It's accomplished by spraying really clean water into the engine's air intake while spinning it with the starter. Even though I didn't see it, I'm sure both engines got their "bath".
