Piper PA-61 Aerostar (Ted Smith 601)

The airplane crashed into rising terrain after departure from an uncontrolled public airport. The runway used by the pilot is 4,600 feet long and has a 1.8 percent upward gradient. The density altitude was 4,937 feet msl, and a slight quartering tailwind existed at the time. The pilot held in position, powered up the engines, and started his departure. The airplane was observed using most of the runway length before rotation and then it assumed a higher than normal pitch attitude in the initial climb. Witnesses watched the airplane turn left following the route of a canyon and into rising terrain. The reciprocal runway departs towards decreasing elevations. In the area of the crash, two witnesses reported the airplane was at a low altitude, nose high, and wallowing just before it descended into a drainage area 0.69 miles from the runway. Post accident examination of the engines revealed worn camshaft lobes and tappets, which would negatively affect the ability of the engines to produce full rated power. One engine exhibited severe rust on the entire crankshaft. The accident site was located in a canyon, and the wreckage and ground scars was confined to an area about the diameter of the wing span. Major portions of the airframe and most of the engine accessories were consumed by a post accident fire. Examination of the wreckage established that all major components of the airframe and powerplants were at the site.

The airplane was destroyed during an attempted forced landing following an in-flight fire in cruise flight. The pilot was reported to be flying the airplane to an airport in order to have maintenance work performed on the right engine due to a boost problem. It was reported that the pilot had another mechanic at another airport look at the airplane. A work order for a transient airplane was found that indicated work performed on the right engine turbocharger system about 1 month before the accident. The work order shows that the wastegate oil filter was found clogged and collapsed and that it was cleaned, straightened and reinstalled. The pilot operated the airplane with a right engine boost problem. The boost problem with the right engine is evidenced by the previous work order, the excessive amount of runway used during takeoff, the reported smoke from the right engine after takeoff, and the airplane not climbing as expected after takeoff. Due to the reduced power from the right engine, the pilot was required to apply left brake in order to maintain directional control during takeoff, as evidenced by the blued left brake disk with metal transfer into the relief holes and slots. As a result of the pilot using left brake during takeoff, a fire erupted in the left wheel well, which spread to the aft fuselage. This is evidenced by the sooting, fire, and heat damage to the wheel well, the carpet above the wheel well, and aft fuselage. The fuselage immediately behind the baggage compartment had extensive fire damage. The damage in this area included blistered paint on the upper surface, and a two foot square section of the left fuselage skin that was burned away. The area that was burned away was in the vicinity of the hydraulic fluid reservoir. The aluminum hydraulic fluid reservoir was not found, only the steel filler neck, mounting screws, and cap were found. No evidence of fire was found within the right main landing gear wheel well or in the engine compartments. A witness reported seeing the airplane flying south and trailing smoke then banking to the left making a complete circle before descending and ultimately impacting the ground.

The pilot was aware of thunderstorms along his route of flight. He paralleled a line of storms for about 20 minutes looking for a hole in the storms to penetrate, without any success. He turned, and climbed to an altitude of 13,500 feet. He noticed what seemed to be an opening to the south, and turned southbound, through the hole, for about 2 or 3 miles, and then the hole closed. He turned the airplane to the right to reverse course, when he inadvertently penetrated a cell. At this point he said he "lost control of the airplane, and was turned upside down…...heading straight down towards the ground...…traveling at a high rate of speed..….the airspeed indicator was pegged." At an altitude of about 2,000 feet, he was able to level the wings, reduce power and raise the nose. He said he was then able to slow the airplane for a "controlled crash landing," straight a head in a sugar cane field. According to the Sheriff's Report, he struck the field in which the aircraft was lying in immediately after slowing the airplane. The distance from the initial impact area to where the airplane came to rest was about 75 yards.

The airplane collided with mountainous terrain during approach to the destination airport. While approaching the airport, the pilot requested vectors for a localizer approach to runway 19. Due to traffic, air traffic control (ATC) issued the pilot a holding clearance. The airplane was approaching the holding fix about 8,000 feet, when the pilot advised ATC that the airplane was picking up a little ice. ATC initially offered an amended clearance of 9,000 feet, but the pilot declined. Subsequently, he accepted the clearance and climbed back to 9,000 feet. ATC then told the pilot that after one more airplane had landed, he would be issued an approach clearance. The airplane was about 9,200 feet when the pilot replied "thank you." Review of radar data revealed that the accident airplane made one complete 360-degree turn, and one 270-degree turn on the non-holding side of the published holding pattern. During the two turns, the airplane descended to approximately 8,400 feet, climbed to 8,900 feet, then descended again to 8,300 feet. The two turns were tighter than the expected standard 2-minute turns in a holding pattern, with radii ranging from 0.3 to 0.4 nautical miles and 0.1 to 0.2 nautical miles respectively. Following the two holding turns, no more radio transmissions or radar returns were received by ATC. Examination of the wreckage did not reveal any preimpact mechanical malfunctions. Another pilot flying in the area reported moderate rime ice at 8,000 feet, but added that he climbed out of the ice and was between cloud layers at 9,000 to 10,000 feet.

Witnesses watching N900CE's approach for landing to runway 17 at Marco Island Executive Airport stated the pilot appeared to have difficulty aligning the Machen modified Aerostar with the runway centerline. They stated the aircraft appeared unstable about the yaw and roll axes, and appeared too fast. Winds were from the southwest at about 15 knots, gusting to about 20 knots. One pilot/witness close to the touchdown area saw the right wheel touch down instantly, and climb back up to about 50 feet, agl without the full addition of engine power. Most witnesses thought he was either performing a go-around or an extended touch down further down the runway. The airplane continued, "..more and more wobbly" until it entered a climbing attitude and sharp left bank and turn. About half way down the runway the left wing dropped until it contacted the terrain left of the runway, and the aircraft slid into mangrove trees and burned. During postcrash examination, flight control continuity from surface to cockpit floorboards was confirmed. No condition was found with either engine or propeller that would have precluded proper operation, precrash. A witness listening to the pilot's initial radio call up for approach and landing stated that no abnormality was reported by the pilot. Postmortem toxicology testing on specimens obtained from the pilot by the FAA Toxicology and Accident Research Laboratory and the Dade County Medical Examiner revealed quinine found in the blood and urine. The side effects of quinine can include disturbances of vision, hearing, and balance.

The pilot reported that after rotation, he obtained a positive rate of climb. At 110 knots, with the landing gear retracted and the wing flaps at 10 degrees, he noticed a right roll, a drop in climb performance, and a drop of manifold pressure on the right engine to at least 34 inches. The left engine maintained 42 inches. The pilot decided that, due to a "very minimum climb rate, rising terrain ahead, [and] airspeed not increasing," he would land the airplane in a small field about 1/4 mile and 50 degrees to the left. The pilot abruptly lowered the nose of the airplane and raised the flaps to gain airspeed, then landed with a nose-high attitude and the landing gear partially extended. Post-accident examination of the airplane revealed there was vertical compression to the belly area, the fuselage was spilt across the top at the aft end of the cabin, and both wings were damaged, with the left wing buckled downward just inboard of the engine. Examination also revealed that a clamp on the right engine intake manifold was loose. An estimated takeoff weight placed the airplane 74 pounds over the maximum allowed of 6,200 pounds. The type certificate holder estimated that with the airplane at 6,400 pounds, climbing at 110 kts, and with a partial power loss down to 26 inches on one engine, the rate of climb should have been 1,150 fpm with flaps and landing gear up, and 830 fpm with flaps 10 degrees and landing gear down. Higher terrain was to the east, and lower terrain was to the west. Terrain elevation for a straight-out departure was 25 feet above the runway at 0.5 nm, and 70 feet above the runway at 2.8 nm. The pilot reported his total flight experience as 15,000 hours, which included 13,000 hours in multi-engine airplanes, and 30 hours in make and model, all with the preceding 90 days.

The airport consisted of a single runway oriented on a heading of 140/320 degrees. A taxiway oriented on a 120 degree heading intersected the runway at its midpoint. The pilot reported that the visibility was 500-1,000 feet with fog at the time of departure. Before he took off, the pilot asked his passenger to walk the length of the runway to observe any obstructions, due to the reduced visibility. The pilot then taxied to the run-up pad, set the heading of his HSI to 120 degrees, and initiated the takeoff. When the airspeed reached 80 knots, the pilot realized he had initiated the takeoff on the taxiway instead of the runway. He aborted the takeoff and attempted to maneuver the airplane to the runway. The airplane crossed the runway, impacted a tree, and came to rest upright in a cornfield. The weather reported at the time of the accident at an airport 9 miles away was: wind from 320 degrees at 2 knots; visibility 1/16 mile with fog; sky partially obscured; ceiling 200 feet overcast.

While on a cross-country flight, according to radar data and weather information, the pilot descended below terrain clearance altitude and entered IMC conditions. The aircraft impacted a mountain peak approximately 100 feet below the summit. No flight plan had been filed and the pilot was not instrument rated.

During the takeoff roll on runway 25 at Randers Airport, the right engine lost power then failed. The pilot continued the takeoff procedure and completed the rotation. Just after liftoff, while in initial climb, smoke spread from the right engine into the cockpit. The pilot attempted an emergency landing when the aircraft crash landed, collided with trees and came to rest about 500 metres past the runway end. The pilot escaped uninjured and the aircraft was damaged beyond repair.

While operating in IMC, the pilot was vectored to the final approach course for an ILS approach. Weather at the airport was ceiling 200 feet and visibility 3/4 mile in mist. The pilot was cleared for the approach, which he acknowledged. No other transmissions were received from the accident airplane. Radar data showed the airplane intercept the final approach course, then track inbound. The airplane crossed the outer marker 420 feet below the glide slope. The last radar return showed the airplane at 440 feet agl, 3.9 miles from the runway. The airplane impacted the ground at a shallow angle about 1 mile north of the airport on the opposite side of the missed approach procedure. The elevation of the accident site was approximately 40 feet lower than the airport. The pilot had about 350 hours of total flight
experience. No pre-impact failures were identified with the airframe, engines, flight controls, or flight instruments.
