Plain English Summary

1/10 complexity

What this does: This is a mandatory safety notice (called an Airworthiness Directive) that orders owners and operators of specific Cessna 150 Aerobat aircraft to inspect or repair the pilot/passenger seat frames to prevent potential failure.

Who it affects: Only applies to Cessna 150 Aerobat models with serial numbers between A1500277–A1500647 and FRA1500167–FRA1500291.

What must be done: Follow the technical instructions in Cessna Service Letter SE 77-40 (a manufacturer bulletin that details the specific seat frame work required).

When: The work must be completed within 100 hours of flight time after 28 February 1978.

Why it matters: Faulty seat frames in aerobatic aircraft pose a serious safety risk during high-G maneuvers; this directive ensures the structural integrity of the seating.
