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
During cruise flight the pilot observed the hydraulic system pressure fluctuating. The pilot immediately went into a hold pattern and attempted to ascertain the problem. After repeated attempts the pilot was able to lower the nose gear and the right main gear. During final approach for the emergency landing the pilot feathered the left engine and on touchdown the right engine was feathered. Touchdown was made on the right gear with full right aileron. The pilot lost aileron lift and the aircraft settled onto the left gear and the gear collapsed. Investigation revealed that the left, main gear hydraulic system plumbing had a fatigue hairline crack in the pressure line leading from the pump to the cylinder. The fracture was in the 90 degree bend of the line.
