Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The acft made an emergency gear up landing when both the normal and emergency extension systems failed to function properly. A mechanic was later able to extend the gear with the acft on jacks by repeatedly cycling the selector switch. It was determined that the solenoid on the landing gear hydraulic manifold assembly had malfunctioned, leaving the selector valve assembly stuck in the up position. Cessna service letter SE76-24 recommends replacement of the solenoid with an improved version. According to the mechanic, this had not been accomplished prior to the accident.
