The Federal Aviation Administration is issuing a new airworthiness directive that mandates specific maintenance actions for certain Pilatus Model PC-12/47E airplanes. This rule adopts requirements originally developed by the European Union Aviation Safety Agency to address a safety issue with the aircraft’s stall warning protection system.
Why it matters: This is a straightforward safety fix for a specific aircraft model. While the issue does not ground the planes immediately, ignoring it leaves pilots vulnerable to confusing and potentially disruptive system warnings during critical phases of flight like landing. The cost impact is relatively low, with the FAA estimating about $255 per plane for labor, though some costs may be covered under warranty.
Who it affects
- Owners and operators of Pilatus Model PC-12/47E airplanes (serial numbers 1720 and 2001 through 2476)
This rule was issued by the Federal Aviation Administration in the Federal Register; readers should consult the original document for full technical details before relying on this summary.
