Flight Details
A pilot was conducting an IFR flight at an altitude of 13,000 feet. During the cruise, the aircraft was skimming the tops of ragged cumulus buildups. The pilot estimated the airplane was approximately 200 to 300 feet below the top of one such cloud when severe turbulence was encountered.
Encounter with Turbulence
The severe turbulence caused an altitude loss of 1,500 to 2,000 feet. The aircraft sustained substantial damage during the encounter. After the occurrence, the pilot noted that the 'gear up' light was not illuminated, the airspeed indicator was inoperative, and some rivets were popped on the wings.
Landing Gear Issues
Upon reaching the destination, the pilot was unable to extend the landing gear using either the normal or emergency extension systems. Consequently, the pilot diverted to Redbird Airport and performed a wheels-up landing. This landing resulted in minimal additional damage to the aircraft.
Weather Briefing and Post-Flight Examination
The pre-flight weather briefing had called for turbulence along the route with occasional light to moderate activity below 8,000 feet. The pilot reported that conditions were smooth prior to the accident. After the aircraft was placed on jacks, the landing gear motor release handle was 'jiggled,' and subsequently both the normal and emergency gear extension systems operated normally.
