What are some of the most common problems you find that other shops mis or never seem to catch?
Most shops are (of course) competent on aircraft they are familiar with or work on daily. We find they do not catch many of the persistent or problems SB’s which are important because they can’t know where to always look. We also find they don’t know where the most likely spots exist for corrosion along the bottom spar cap (for example) and the lower longerons in the wings. The 4130 tubular rust is another problem as is the gear pre- load settings and wear on the nose gear truss (and trunnion) as also is the landing gear bungies. Amazingly, you would be surprised as to how many shops don’t have a full set of Mooney Service Manuals and/or factory rigging tools but are still doing M20 inspections.
