Timing is everything
Roulettes Grounded
Like all Air Force aircraft, the PC-9/A is subject to regular maintenance and engineering reviews. These engineering reviews have located
cracks in the nose-landing–gear folding strut. Consequently, Air Force is assessing the implications of these cracks, so as to ensure the aircraft meet Air Force’s strict safety standards. Therefore, as a precautionary measure, each PC-9/A will undergo an additional engineering review, and remediation repairs, before returning to normal flying activities.
