Plain English Summary

2/10 complexity

What this is: An Airworthiness Directive (mandatory safety order) from the Civil Aviation Safety Authority (CASA) for certain Cessna aircraft.

Who it affects: Owners and operators of Cessna 310 model aircraft with serial numbers before 35139.

What it requires: You must inspect specific structural parts of the aircraft—the vertical angle (a structural support piece) and the spar cap (a reinforced section of the wing's main beam)—for interference (unwanted contact or rubbing). This inspection must happen every 25 hours of flight time.

Why it matters: Interference between these structural components could indicate wear, improper installation, or structural damage that might compromise the aircraft's safety. Regular checks catch problems before they cause in-flight failures.

Technical reference: The directive points to Cessna Service Letter No. 310-3 for detailed inspection instructions.
