Plain English Summary

2/10 complexity

What this is: A safety rule requiring regular inspections of specific structural parts on certain Beechcraft aircraft to prevent dangerous cracks.

Who it affects: Owners and operators of Beechcraft 56TC and A56TC aeroplanes with serial numbers TG-2 through TG-94.

What you must do: Inspect two specific fuselage bulkheads (structural frames at positions FS 257.6 and FS 271.92) for cracks, following the technical procedures in Beechcraft Service Instruction No. 0990.

When to do it:

First check: Within 100 hours of flying time after 30 April 1979
Repeat checks: Every 500 flight hours or once per year, whichever comes first

Why this matters: Cracks can develop where the horizontal stabiliser (the tail wing) attaches to the fuselage. If undetected, these cracks could compromise the aircraft's structural integrity and safety.
