According to the pilot, the landing gear and flaps failed to retract after departure. After verifying that the hydraulic pump circuit breaker had not opened and noting that the hydraulic pressure gauge indicated zero, he was able to successfully retract both the landing gear and wing flaps using the emergency hydraulic hand pump. Upon arrival at his destination, he again used the hand pump to extend both the landing gear and wing flaps. After touchdown, he applied the wheel brakes in an effort to slow and steer the airplane, but the airplane did not slow down. The airplane exited the side of the runway, proceeded down an embankment, and came to rest on its left wing and hull sustaining substantial damage to the left wing and fuselage.
Postaccident examination of the brake and flight control systems revealed no preaccident mechanical malfunctions or anomalies that would have precluded normal operation. Although the pilot reported the failure of the airplane's landing gear and wing flap hydraulic system, it was independent of the brake system and therefore was not examined.
Probable Cause: The pilot's loss of directional control while landing, which resulted in a runway excursion and collision with terrain.
