We received over 800 responses to our question last week on annual
inspections. Just over half (51 percent) of our respondents felt the annual
inspection requirement for certificated, non-commercial aircraft needs to be
revised. Only 6 percent felt that hours an aircraft is flown only (e.g., every
100 hours) should be the primary basis for determining when a certificated,
non-commercial aircraft should be inspected. On the other hand, 47 percent
claimed the hours flown and calendar time (e.g., every 100 hours or biennial)
should be the main determining factor. Regardless of what system should be
implemented, several comments we received hailed the owner/operator as the key
in this situation. As one person wrote, "Learn to know your airplane inside and
out, don't rely on your mechanic to find everything."
