The FAA has issued a final airworthiness directive (AD) for certain Pilatus Aircraft Ltd. Model PC-12/47E airplanes to address a safety issue. The problem stems from inboard flap fairings with an incorrect shape, potentially leading to chafing with a tension rod, which could cause a failure in the flap system and reduce airplane control. The AD requires inspections of the affected parts to check for chafing and to ensure the correct shape; corrective actions must be taken if necessary. The rule applies to specific serial numbers and outlines inspection requirements, with expected compliance costs detailed.
Simple Explanation
The FAA wants to make sure some Pilatus planes are safe by checking certain parts to ensure they are the right shape and not damaged. This will help keep the planes flying smoothly and safely.
