Incident
Sep 18, 1995 · Lafayette, LA
a short in the 'jam proof system' solenoid valve which prevented activation of the backup hydraulic system and resulting in a cyclic hardover. Factors were the contaminated hydraulic fluid and the resulting jammed actuator (longitudinal control slider).
These match the airframe or engine model. Whether each one applies, and whether it's been complied with, depends on serial numbers, equipment and logbook entries. Applicability must be confirmed by a mechanic against the aircraft's records.
Engine (250-C20 SER)Only with: Engines that do not have turbine energy absorbing ring RRC P/N 23035175, or an equivalent FAA-approved serviceable ring, installed.
