HISTORY OF FLIGHT
On December 9, 1999, at 1512 central standard time (cst), a Cessna 525, N525KL, operated by an airline transport pilot, was destroyed when it impacted a hillside on the northwest edge of the city of Branson, Missouri, 4.3 statute miles from its destination, the M. Graham Clark Airport, Point Lookout, Missouri. A post-crash fire ensued. The pilot, pilot-rated passenger, and four passengers in the cabin section of the airplane, were fatally injured. Instrument meteorological conditions prevailed at the time of the accident. The business flight was being conducted under 14 CFR Part 91. An instrument flight plan was on file. The cross-country flight originated at St. Louis, Missouri, at 1411 cst.
At 1339 cst, the pilot contacted the Federal Aviation Administration Flight Service Station at St. Louis, Missouri, by telephone, and obtained a preflight weather briefing for an instrument flight rules (IFR) flight from St. Louis to Point Lookout. Following the briefing, he filed an IFR flight plan.
The operations manager at M. Graham Clark Airport said that the pilot, while on the ground at St. Louis, contacted him by telephone, at 1348 cst, inquiring what the weather was at the airport. The operations manager told the pilot that the weather was pretty poor and gave him the most-recent observation, which he took a few hours earlier. "He (the pilot) asked me if I could listen for him to call on the CTAF (common traffic advisory frequency) and take a weather observation at that time for him. About 2:40 [p.m. cst] he called me on CTAF and said he was about 10 or 15 minutes out. He asked me if I could call him back with a current weather in about 10 minutes." At this time, another pilot departing the airport in a Cessna 421, N1527G, gave the pilot a pilot report (PIREP) for the field.
The Cessna 421 pilot told the pilot of N525KL that the clouds were approximately 1,200 feet mean sea level (msl). The pilot of N525KL radioed the airport manager and told him to disregard the observation; he was going to Springfield, Missouri.
At 1411 cst, the Air Traffic Control Tower at Lambert Field/St. Louis International Airport, cleared N525KL for takeoff. One minute later, the pilot was instructed to contact departure control.
At 1447:12 cst, N525KL checked in with Springfield Air Traffic Control Tower (ATCT) Approach Control (henceforth, referenced as Springfield Approach Control), and stated that he was descending at pilot's discretion to 10,000 feet msl. Springfield Approach Control told the pilot to maintain 10,000 feet msl and expect the ILS approach to runway 2 at the Springfield-Branson Regional Airport.
At 1449:29 cst, Springfield Approach Control cleared N525KL to 6,000 feet msl. N525KL responded, "okay we're down to six thousand..."
At 1455:48 cst, Springfield Approach Control instructed N525KL to turn left to a heading of 200 degrees. N525KL acknowledged the instruction.
At 1456:30 cst, Springfield Approach Control issued to N525KL, "pilot's discretion descend and maintain four thousand." N525KL responded, "discretion to four thousand for Kilo Lima."
At 1501:01 cst, Springfield Approach Control instructed N525KL to descend and maintain 3,000 feet msl, and turn right to a heading of 280 degrees. N525KL responded, "Okay we have a request. Can you give us, we would like to try Point Lookout, the weather doesn't look that bad here now, and then, if we miss, we'll come back up with you." The Springfield Approach controller asked N525KL's pilot what kind of approach did he want. The pilot responded, "We'll take the GPS to [runway] one-one."
At 1501:32 cst, Springfield Approach Control instructed N525KL to "descend and maintain three thousand until RAWBE, cleared [for the] GPS [runway] one-one approach." N525KL responded, "Okay, we're down to three [thousand], and we're direct RAWBE, and we're programming that now."
At 1507:08 cst, the display of ASR-8 radar at Springfield Approach Control showed N525KL cross the RAWBE waypoint at 3,000 feet msl, and turn to a heading of 116 degrees magnetic.
At 1507:17 cst, Springfield Approach Control radar showed N525KL descending out of 3,000 feet msl.
At 1508:04 cst, Springfield Approach Control radar showed N525KL level off at 2,500 feet msl.
At 1508:51 cst, Springfield Approach Control said, "Citation five Kilo Lima, change to advisory frequency approved. Call me back with your cancellation or your miss." N525KL responded, "Okay we're, we're RAWBE inbound and we will call you on the miss or cancellation."
The operations manager at M. Graham Clark Airport said that he was at his desk in the airport operations office when he heard the pilot on the airport's common frequency radio say, "Citation 525KL is RAWBE inbound on the GPS 11 approach." The operations manager said he went to the door of the building to see if he could hear the airplane go missed approach. The weather was no better than it had been earlier. He listened for about 15 to 20 minutes, then went back in. He said that he thought he must have missed hearing the airplane and that the airplane probably went back to Springfield.
At 1509:01 cst, Springfield Approach Control radar showed N525KL begin a descent out of 2,500 feet msl.
At 1509:46 cst, N1101U, contacted Springfield Approach Control and inquired if N525KL had cancelled yet, or if he was still on the approach? Springfield Approach Control answered, "Still on the approach, I show him just at the final approach fix now."
At 1509:48 cst, Springfield Approach Control's last radar contact position for N525KL, showed the airplane 5 nautical miles (nm) from the M. Graham Clark Airport on a 296 degree radial from the airport, at 2,100 feet msl.
