Plain English Summary

1/10 complexity

What this is: An Airworthiness Directive (a mandatory safety order) issued by the Civil Aviation Safety Authority requiring owners to fix a potentially fatal equipment fault in specific aircraft.

Who it affects: Owners and operators of Mitsubishi MU-2B-25, -26, -26A, and -40 model aeroplanes with serial numbers 313SA, 321SA, 365SA, and 397SA through 457SA.

What you must do: Follow the manufacturer's Service Bulletin SB 057/32-010 to repair or modify the landing gear aural warning system. This work must be completed within 100 flight hours after 31 July 1986.

Why it matters: The warning bell or alarm that alerts pilots if the landing gear is not properly extended may fail to sound during certain landing approaches. This creates a significant risk of the aircraft landing with its wheels retracted, which can cause catastrophic damage, injury, or death.
