7.25.2 RVSM Critical Region Visual Inspection

The RVSM critical region is a 24 x 24 inch area around the static ports on both sides of the airplane. The

corners of the RVSM critical region are to be marked on the aircraft with placards or paint of a

contrasting color (see Figure 7-11.) The RVSM critical region must meet the following visual inspection

criteria:

1. The fuselage skin must be free from damage. All skin repairs within the RVSM critical region must

be flush (no external doublers). If any damage is found, the area must be repaired. Locations of

existing protruding head rivets in frames and skin laps are acceptable.

2. The paint (including stripes) must be uniform and smooth. Remove any paint blisters or flaking and

sand smooth. Any decals or placards must be flush with no peeling edges.

3. The static ports must be free from any corrosion, elongation of holes, deformation or obstructions. If

any damage is found, replace the static port.

4. The oxygen servicing door on the right hand side must close approximately flush with the fuselage

skin and be free from damage or deformation. For model 300 only, the ELT access hole cover on the

right hand side must be in place.
