Pacific Air Express - USA

The aircraft crashed off the end of runway 23 during an attempted go-around after touchdown. The pilot stated that after the aircraft touched down approximately 300 feet down the 2,760 foot runway he raised the flaps along with the nose of the aircraft to slow down. Brakes were applied and the left main gear skidded 2/3 the way down the runway at which time full power was applied to go-around. The aircraft mushed off the end of the runway where it contacted a rock pile and was destroyed by impact and post crash fire. The pilot reported winds from 270° at 10 knots when the accident occurred.

During takeoff at about 50 feet agl and 4,000 feet down runway 04R, the right engine lost power. According to the pilot, his airspeed was 105 mph and the right engine 'popped' before it lost power. He also stated that power on the left engine deteriorated after the the right prop was feathered. The aircraft went into a right bank and the pilot maintained control of the aircraft until impact with the water. Examination of the right engine revealed that the right magneto, american bosch sb9ru-3, ser #b88470, was not timed correctly. Disassembly of the magneto revealed that all except 11 distributor gear teeth were stripped off. At the time of the power loss of the right engine, about 5,000 feet of rwy was remaining.

During arrival, a descent was begun from 8,000 to 7,000 feet msl at 0151 hst. At 0155 hst, the aircrew was cleared for a visual approach from 7,000 feet msl and a rapid descent was started with 20° of flaps and approximately 25 inches ap (manifold pressure). The aircraft was maneuvered to intercept the ILS localizer and glide slope as a reference. After intercepting the glide slope at about 3,000 feet, the pilot-in-command (pic) called for 2,250 rpm and gear extension. While descending thru approximately 2,000 feet, he noticed the aircraft slowing down and descending below the glide slope, so he called for a power increase to 27 inches map. At about that time, the aircrew noted that the engines were not responding and had lost power. Subsequently, a forced landing was made in a sugar cane field with the gear in a transient position. The fuel selectors were found positioned to fuel tanks containing fuel, but the positioning during the descent was not verified. The temperature and dew point were 72° 65° F. This would have been barely within the envelope for carburetor ice on icing probability charts. All three occupants were uninjured.
