N833DF is coming back on Wednesday. I verified with Matt that the airplane will be ready, so I’m leaving for Georgetown around 6 or 7am so I can get there early.  I’m still working on travel arrangements and logistics, but I’m definitely going and will leave my car there if need be.

The test plan is shown below as it exists in my head. I’m sitting in Vermont this morning, on Beverly’s birthday, waiting for my flight home. I will share this plan with Matt and keep thinking about it as I fly home. During the flight I’ll be reading the normal checklist and Comanche Association Manual on the PA30 to refresh my memory. I have an abbreviated checklist I’ll use in the airplane.

Please leave a comment if you have an idea that would improve my safety during this test, as defined below.
