NTSB Factual Report

HISTORY OF FLIGHT

On August 4, 2002, at 1335 eastern daylight time (edt), a Piper PA-46-350P, N316PM, owned and piloted by a private pilot, impacted the terrain on the extended centerline of runway 27, 1.12 nautical miles (nm) from the approach end, at the Southwest Michigan Regional Airport (BEH), Benton Harbor, Michigan. The pilot was performing a forced landing after experiencing a total loss of engine power during cruise flight. The aircraft was substantially damaged. The pilot and his two passengers were fatally injured. Visual meteorological conditions prevailed at the time of the accident. The personal flight was operating under the provisions of 14 CFR Part 91 on an instrument flight rules (IFR) flight plan. The flight departed Joe Foss Field Airport (FSD), Sioux Falls, South Dakota, at 1100 edt, and had the intended destination of Toledo Express Airport (TOL), Toledo, Ohio.

According to information provided by the Federal Aviation Administration (FAA), the pilot of N316PM contacted Sioux Falls Departure Control at 1101 and was instructed to turn on course and climb to 10,000 feet. At 1102, N316PM was told to contact Minneapolis Air Route Traffic Control Center (ARTCC) and was subsequently cleared to climb to flight level 190 (19,000 feet). At 1213, N316PM was told to contact Chicago ARTCC. At 1319, N316PM reported a loss of engine power and requested clearance to the nearest airport. Chicago ARTCC issued a descent clearance from flight level 190 to 11,000 feet. At 1321, Chicago ARTCC cleared N316PM to BEH.

At 1321:57 (hhmm:ss), Chicago ARTCC contacted South Bend Approach Control (Approach Control) and informed them of the engine failure and that N316PM was going to land at BEH. At 1322:34, Approach Control informed Chicago ARTCC that they had radar contact with N316PM. At 1324:08, N316PM established radio contact with Approach Control.

At 1324:24, the pilot of N316PM reported that he did not have BEH in sight and that he was attempting to acquire the airport on his global positioning system (GPS) receiver. At 1324:30, Approach Control replied that N316PM was "three miles northwest of [BEH]" and asked if the pilot wanted "vectors to stay there, or you want to do it on your own?" The pilot of N316PM replied "ah, why don't you just kinda ah let us, give us vectors around to [BEH] please." At 1324:40, Approach Control confirmed that he would provide radar vectors and told N316PM to turn left to a heading of 070.

At 1325:53, the pilot of N316PM told Approach Control that his rate-of-descent was 1,000 feet/min. Approach Control confirmed the transmission and told N316PM to expect runway 27 at BEH. At 1327:25, Approach Control told N316M to turn right to a heading of 140. At 1329:24, the pilot of N316PM reported descending through 8,000 feet. At 1329:31, Approach Control told N316PM to turn right to a heading 270. At 1330:33, Approach Control told N316PM to fly heading 280.

At 1330:58, Approach Control told N316PM that the airplane was on an eight mile final for runway 27. The pilot of N316PM replied that he still did not have the airport in sight. Approach Control replied that the airport was "twelve o'clock, and ah seven miles." At 1331:43, the pilot of N316PM reported again that he had not visually acquired the airport. At 1332:39, Approach Control announced the airport was "twelve o'clock, six miles." At 1332:44, the pilot of N316PM reported having the airport in sight. At 1332:47, Approach Control inquired if the airplane had sufficient altitude to reach the airport and the pilot of N316PM replied "ah, think we'll be okay." Aircraft radar track data indicated N316PM was at approximately 3,800 feet at 1332:44.

At 1333:08, N316PM was cleared for the visual approach to runway 27 at BEH. The pilot of N316PM replied "six papa mike we're cleared for the visual Benton Harbor and we're planning on two seven, have the field in sight." At 1334:05, the pilot told Approach Control that he was changing to the local airport advisory frequency. No additional communications were received from N316PM. A transcription of the voice communications between South Bend Approach Control and N316PM is included with the docket material associated with this factual report.

Aircraft radar track data for the period before and after the reported accident time was obtained from the South Bend Approach Control and Chicago ARTCC. The obtained data indicated a single aircraft transmitting a discrete transponder beacon code (3614) maneuvering near BEH before the time of the accident. At 1325:22, the airplane was positioned about 1.3 nm north of BEH at 13,500 feet. The aircraft then traveled northeast about 5.0 nm prior to turning to the southeast. At 1327:58, the airplane was positioned about 7.0 nm northeast of BEH at 10,400 feet. The airplane continued southeast for another 5.0 nm prior to turning onto the extended runway 27 centerline.

At 1331:15, the airplane was established in-bound for runway 27 and was about 9.5 nm from the runway threshold at 6,700 feet. The airplane continued on a westerly heading for the remainder of the radar data. At 1333:32, the airplane crossed over the locator outer marker, 4.8 nm east of the runway threshold, at 2,600 feet. At 1334:28, the airplane was positioned about 2.8 nm east of the runway at 1,900 feet.

The last radar return, recorded at 1335:29, was about 1.5 nm east of the runway at 1,300 feet. The last radar position was about 0.4 nm east of the accident site. Plots of the radar track data, along with a copy of the source data, are included with the docket material associated with this factual report.

According to a local law enforcement incident report, there were five witnesses to the accident. Two of the witness reported seeing the airplane "spiraling down and crashing into the ground." The three other witnesses were driving on Territorial Road when they noticed the accident airplane traveling on a westerly heading with its propeller not rotating. The witnesses reported seeing the airplane dive towards the ground before losing sight of the airplane. The incident report is included with the docket material associated with this factual report.

AERODROME INFORMATION

The Southwest Michigan Regional Airport (BEH) is located about two miles northeast of Benton Harbor, Michigan. The airport has three asphalt runways: 09/27 (5,109 feet by 100 feet), runway 13/31 (3,662 feet by 100 feet) and runway 18/36 (2,498 feet by 100 feet). The general airport elevation is listed as 643 feet mean sea level (msl).

The elevation of the runway 27 threshold is listed as 642.8 feet msl. Runway 27 also incorporates a secondary (displaced) threshold, positioned 571 feet from the approach end of the runway. Runway 27 is serviced by an instrument landing system (ILS) used for precision instrument approaches. The locator outer marker is positioned 4.8 nm from the runway threshold. A medium intensity approach lighting system precedes the runway threshold.

There are high-voltage power lines that run perpendicular to the extended runway 27 centerline. One of the tower structures is located near the extended centerline, about 1.0 nm from the runway threshold, and extends to 755 feet msl.

FLIGHT RECORDERS

The accident airplane was not equipped, nor was it required to be equipped, with a cockpit voice recorder (CVR) or flight data recorder (FDR). However, the airplane was equipped with a Flightcom DVR 300i (Digital Voice Recorder Clock). The system is voice-activated and digitally records to a five-minute continuous loop that captures all audio transmitted to the pilot's headset. The unit is to be used with a 9-volt backup battery that preserves the five-minute recording for approximately 1 to 2 months. When inspected at the accident site, the backup battery was not installed.

WRECKAGE AND IMPACT INFORMATION

The National Transportation Safety Board's on-scene investigation began on August 4, 2002.

A global positioning system (GPS) receiver was used to identify the position of the accident site as 42-degrees 07-minutes 39.4-seconds north latitude, 86-degrees 23-minutes 42.4-seconds west longitude. The aircraft impacted an established apple orchard. The wreckage was located on the extended runway 27 centerline, about 1.12 nm from the runway threshold. The main wreckage was positioned approximately 400 feet from the high-voltage power lines that run parallel to Tower Road, a north/south road. The GPS elevation of the accident site was 680 feet msl.

The wreckage was surveyed using an impulse laser unit with prism pole. The first evidence of ground contact was about 71 feet northeast of the main wreckage in high grass/vegetation. An 18 foot swath through the high vegetation, orientated on a 260-degree magnetic heading, preceded the initial ground impact. The first ground impact occurred 40 feet northeast of the main wreckage, followed by an impact crater that contained one propeller blade. The main wreckage was located 33 feet southwest of the impact crater, orientated on a southerly heading.

The main wreckage consisted of the fuselage, empennage, left and right wings, and all flight control surfaces. The forward cockpit area was offset from the fuselage about 42 degrees left of centerline. The left wing was found separated from the fuselage and was positioned inverted, next to the left side of the fuselage. The right wing remained partially attached to the fuselage. The empennage remained attached to the fuselage. Flight control continuity was established from the individual flight control surfaces to the forward cockpit area. The landing gear, wing flaps, and spoilers were found in a fully retracted position.

The engine remained attached to the fuselage firewall by its mount assembly. The crankcase contained a crack between the right rear sump flange and the forward side of the number six cylinder deck. The crankshaft was seized. The engine was removed from the wreckage and shipped to the manufacturer for additional examination and testing. (See Engine Teardown Examination in the Test And Research section below)

MEDICAL AND PATHOLOGICAL INFORMATION

An autopsy was performed on the pilot on August 5, 2002, at the Lakeland Medical Center, St. Joseph, Michigan.

Toxicology samples for the pilot were submitted to the FAA Civil Aeromedical Institute, Oklahoma City, Oklahoma. A Forensic Toxicology Fatal Accident Report was prepared and the results were negative for all tests performed.

TESTS AND RESEARCH

Engine Teardown Examination:

The engine was examined on August 9, 2002, at the Textron-Lycoming factory located in Williamsport, Pennsylvania. The teardown inspection was supervised by National Transportation Safety Board investigators. The engine teardown revealed that the crankshaft was fract

NTSB Probable Cause

The pilot's failure to maintain airspeed above stall speed resulting in a stall/spin. Additional causes were the pilot not maintaining best glide airspeed and optimal glidepath following the loss of engine power. A factor to the accident was the engine failure due to the fatigue failure of the crankshaft.
