Abstract
We are adopting a new airworthiness directive (AD) for Hamilton Standard Division model 6/5500/F and 24PF and Hamilton Sundstrand Corporation model 14RF, 14SF, 247F, and 568F series propellers. This AD was prompted by the amount of corrosion detected during major inspections (MI). This AD requires incorporating inspections, based on a calendar time, into the propeller maintenance schedule. We are issuing this AD to prevent corrosion that could result in propeller failure and loss of airplane control.
