FAA: PC-12 Bolts Might Be ‘Defective’

The FAA issued an Airworthiness Directive January 16 for PC-12s since some main landing-gear special bolts might be defective. Investigations revealed that bolts with a serial number that starts with “AT” might be brittle, decreasing the specific fatigue life and possibly leading to collapse of the main landing gear during operation with a consequent loss of airplane control.
