First step in checking the engine alignment - measuring the fuselage deck angle on the reference fixture. It shows as 6.9 degrees tail-down.

Second step in checking the engine alignment - measuring the angle of the prop driver with an engineeers square clamped to it. It shows as 7.1 degrees tail-down - a difference of 0.2 degree from the fuselage reference.

Third step in checking the engine alignment - measuring the angle of the prop driver directly. It shows as 82.8 degrees - 7.2 degrees off vertical and thus 0.3 degree different from the fuselage reference. This measurement is potentially less reliable as there is a much smaller area on which to place the base of the digital level.

Fourth step in checking the engine alignment - measuring the angle of the prop driver directly with the digital level in the opposite orientation. It shows as 83.1 degrees - 6.9 degrees off vertical and thus identical to the fuselage reference. This measurement is potentially less reliable as there is a much smaller area on which to place the base of the digital level.
