Probable cause

The shift of the number 2 engine bearing, which in turn blocked oil lubrication, and resulted in crankshaft failure. Also causal, was the pilot's decision to continue toward the airport instead of performing a forced landing to an available field. Factors include the relatively low ceiling, and the pilot's airspeed control.

Analysis

At 6,000 feet, the instrument-rated pilot reported an engine failure, and received vectors to an airport. After the turn, the airplane was 6 nautical miles away, at 4,000 feet. After descending through clouds, the pilot reported, at 1,200 feet, the airport in sight. The airplane then descended rapidly, straight ahead, and hit the ground upright, about 1/2 mile short of the runway. The initial impact point was at the far end of a pasture, which extended off to the pilot's right. The airplane then bounced and collided with a stone wall. Witnesses thought the airplane would make the runway, but it appeared to level off, climb slightly, then fall forward. The stall warning horn sounded upon exiting the clouds, and remained on until impact. The landing gear was in transit at impact. Radar revealed a groundspeed of 81 knots at 1,200 feet, which decreased to 62 knots by 400 feet. The operating handbook stated that power off, 81 knots were required to assure controllability during the flare. The engine crankshaft was found broken in two places. The number two bearing was pounded, and had moved in its saddle. Saddle oil lubrication holes were blocked by metal, and the crankshaft exhibited ladder cracking.

Factual narrative

History of flight

On May 25, 1998, at 1501 Eastern Daylight Time, a Beech A36 Bonanza, N4507S, was destroyed during a forced landing about 1/2 mile north of the Newport State Airport (UUU), Newport, Rhode Island. The instrument rated private pilot and one passenger were fatally injured. Two additional passengers were seriously injured. Visual meteorological conditions prevailed at the accident site, however, the pilot had to fly through an overcast layer during the emergency descent. An instrument flight rules flight plan had been filed for the flight between Nantucket Memorial Airport (ACK), Nantucket, Massachusetts, and Danbury (DXR), Connecticut. The personal flight was conducted under 14 CFR Part 91.

The airplane departed Nantucket at 1432, and climbed to 6,000 feet. At 1448, the pilot contacted Providence Air Traffic Control Tower, East Low Radar position. At 1456:01, he told the controller he had "an in-flight problem," and then reported "we've got an engine failure." The controller acknowledged, and advised the pilot that Newport State Airport was at his 9 o'clock position, 6 miles, and that Quonset State Airport was at his 10 o'clock position, about 8 miles. After giving the pilot the option of either airport, the controller told him to "fly a heading two three zero, the Newport Airport will be at twelve o'clock and five miles." The pilot acknowledged the heading. At 1457:06, the controller advised the pilot that Newport State had a Runway 22, that he would line the airplane up for that runway, that it was at 12 o'clock and 5 miles, and that the pilot was cleared to descend to and maintain 2,000 feet. The pilot acknowledged: "two thousand, zero seven."

At 1457:51, the controller requested "...when you have a chance, souls on board and fuel remaining please." The pilot responded with 30 gallons of fuel and four people. At 1458:17, the controller repeated the descent instructions, and said the airport was at 12 o'clock and 3 1/2 miles.

At 1458:58, the controller stated: "The overcast layer's at twenty three hundred feet. There's a few clouds at nine hundred. You should be able to see the airport shortly - it's twelve o'clock and four miles, correction, ah, three miles." The pilot responded with "twelve o'clock, three miles."

At 1459:17, the controller advised the pilot that the length of Runway 22 was 3,000 feet, and that it was at 12 o'clock and 2 miles. This was acknowledged by the pilot.

At 1459:46, the controller stated: "At pilot's discretion, you can maintain fifteen hundred. Airport's twelve o'clock and a mile and a half." At 1459:51 the pilot responded: "Roger, I'm just coming into the overcast now."

At 1459:54, the controller stated: "Okay, should be coming out of it shortly, the airport will be twelve o'clock and a mile and a half. Runway is straight ahead."

At 1500:19, the pilot stated: "Airport's in sight," and the controller responded with: "Roger, you can remain with me until you land." The pilot responded: "Zero seven."

There were no further transmissions from the pilot. During this time, there was a Piper Navajo on the ground and on a different radio frequency at Newport State Airport. At 1500:53, the Navajo pilot stated he had the Bonanza in sight, and at 1501:18 said: "I'm not sure he's going to make it - he's going pretty low." At 1501:25, the Navajo pilot stated "I believe that plane has crashed...." He then reported smoke and fire and: "That plane has crashed, sir... about one-half mile off the end of Runway two two."

Passengers

The two surviving passengers were sitting in the main cabin of the airplane, in the rearward facing seats. Both were initially wearing headsets.

One passenger, who was sitting behind the pilot, remembered that the pilot did a preflight inspection and an engine run-up prior to departure. He also remembered that the takeoff and climb were normal, except for a whistling noise, which the pilot attributed to "water caught in something." It was raining at the time.

The passenger remembered that while the airplane was in level cruise flight, it suddenly and rapidly decelerated. He could not hear anything abnormal from the engine at this point because he still had his headset on. He then heard the pilot "messing with the engine; working the throttle." It sounded like something was clogging the engine, "like choking a non-starting engine; the rpm was going up and down." He didn't hear any alarms go off. He did hear the radios, and the pilot talking to both air traffic control and his daughter.

At this point, the engine was still operating, and the airplane turned. The passenger thought the airplane was going back toward an airport he had seen. The turn happened "relatively quickly after the problem started." The passenger said the weather was "relatively clear," and he could see the ground. He didn't remember passing through any cloud layers during the descent, but wasn't sure. He was alternately looking both forward, "at peoples' faces," and aft.

The passenger remembered three distinct phases of the event. The first started when the engine began to exhibit a problem, and included the initial steps taken toward trying to solve the problem, as well as the initial turn made by the pilot. The second phase consisted of "time passed" while the airplane was in a descent, and the passenger looking alternately forward and aft. The last phase began when the engine became silent.

When the engine became silent, the passenger looked forward, and heard the pilot's daughter tell her father to restart the engine, to which he responded: "I can't." The passenger then looked toward the intended runway, just over the trees, and thought there was "no way we can make it that far." Just after that, he heard an alarm going off. He then turned back in the seat, faced aft, and buried himself down into the seat until he felt the impact.

The passenger also recalled that in the last phase, the airplane made a left turn, "like a last ditch effort - plan 'B'." He thought one wing went up and one wing went down, perhaps to a 45 degree angle, but was just guessing. He thought that the left wing went down, but could not remember if the pilot held the turn or not.

The passenger remembered hitting the ground, then bouncing. It was a "pretty hard" hit and his eyes were closed. After the airplane stopped, he opened his eyes, and remembered being in smoke and fire. For a few seconds, he might have blacked out.

The passenger got out the plane via the right, aft passenger access door with the other passenger. He did not hear any sounds from the people in the front seats.

When asked, he did not recall if or when the pilot lowered the landing gear prior to impact.

The other passenger was sitting behind the right, front seat passenger. He stated that there was nothing unusual about the airplane, or the startup or takeoff, except for the new headsets. After takeoff, the passenger heard a whistling sound, "like blowing in a bottle." He said that the pilot explained that it was "water or something" and it had just been looked at by maintenance personnel. Aside from the sound, the climbout and level off were uneventful. Everything was "status quo" until the sound of the engine changed, from "humming along" to what it normally sounded like when an engine shut down.

The passenger had unplugged his headset, and didn't hear many conversations from the front seats or any from air traffic control. He said that during the emergency descent, he and the other back seat passenger tried to reassure each other, and that at one time, he did hear the pilot's daughter suggest another engine restart attempt. The passenger did not remember entering any cloud layers, but remembered that when the airplane exited the last layer of clouds, he heard a horn go off. It was originally intermittent, then transitioned to a solid "wahhh" sound,
