Unsafe Condition
The shear pin in the input lever of several Pitch Feel Simulators (PFS) units has failed due to fatigue. The shear pin failure is not always detectable by the flight crew in normal operation. Failure of the shear pins in both PFS units on an airplane could result in loss of pitch feel forces and reduced controllability of the airplane.
Required Actions
Revising the airworthiness limitations (AWL) section of the Instructions for Continued Airworthiness, repetitive functional testing of the pilot input lever of the PFS unit, and corrective actions if necessary, and replacing the PFS units having part number (P/N) 601R92300-3 (vendor P/N TY1910-50A) or 601R92300-5 (vendor P/N TY1910-51A) with PFS units having P/N 601R92300-7 (vendor P/N TY1910-54A).
