Probable cause

The pilot experienced spatial disorientation that resulted in the loss of control.

Analysis

The recently instrument-rated pilot departed on an instrument flight in instrument meteorological conditions with low ceilings and turbulence. Radar data showed the airplane climbed to the assigned altitude but failed to maintain the assigned heading. Radar data indicated the airplane flew a path that included two wide, constant-rate, 360-degree turns to the right. Air traffic controllers twice reassigned the heading, and the pilot acknowledged the instructions each time. About eight minutes after departure, the pilot reported the airplane was in a spin, and the airplane impacted terrain seconds later in a steep, nose-down attitude less than two miles from the airport. The wreckage was found scattered along a path 200 feet long by 80 feet wide in a wooded area. Fuel was present at the site, and examination revealed no evidence of mechanical malfunction of the engine, airframe, or recovered instruments.

Factual narrative

History of flight

On February 6, 2002, at 1402 eastern standard time, a Piper PA-32-300, N4105W, registered to C. A. Griffin, Inc., and operated by the pilot, collided with trees and the ground shortly after takeoff from Dekalb-Peachtree Airport, Atlanta, Georgia. The business flight was operated under the provisions of Title 14 CFR Part 91 with an instrument flight rules flight plan filed. Instrument meteorological conditions prevailed at the time of the accident. The airplane was destroyed, and the private pilot and three passengers received fatal injuries. The flight departed Dekalb-Peachtree Airport, Atlanta, Georgia, at 1353.

At 1341:30, the pilot of N4105W contacted Dekalb-Peachtree ground control and received clearance for his instrument flight to Savannah International Airport in Savannah, Georgia. At 1343:19, the pilot advised ground control the airplane was ready to taxi. The pilot was given taxi instructions to runway 20L. At 1352:06, the Dekalb-Peachtree local controller advised the pilot to taxi into position and hold on runway 20L, and, at 1352:59, the flight was cleared for takeoff and was given a departure heading of 090 degrees. The pilot acknowledged and correctly read back the heading. Once airborne, the pilot was instructed to contact departure control, which the pilot acknowledged.

At 1354:19, the pilot contacted departure control and reported climbing through 1,500 feet. The departure controller advised the pilot of radar contact and instructed the pilot to climb and maintain 4,000 feet, which the pilot acknowledged. According to recorded radar data, the pilot initially flew a 089 degrees magnetic heading and continued eastbound. At 1355:21, the airplane began a right turn.

At 1356:19, the departure controller again instructed the pilot to fly a 090-degree heading, and the pilot repeated the assigned heading. Radar data between 1355:21 to 1356:49, showed the airplane flying a wide right arc back over the Dekalb-Peachtree Airport and the VOR.

At 1357:05, the departure controller contacted the pilot and stated, "november zero five whiskey, you were given a ninety degrees off the runway, correct?" At 1357:10, the pilot replied, "yes sir, we're showing flying eastbound." Radar data at the time of the pilot's reply showed the airplane was on heading of 099 degrees. At 1357:14, the departure controller stated, "okay, just looked like you made a three-sixty out there for a minute." At 1357:19, the pilot replied, "yes sir, we gotcha now." In an interview conducted on February 26, 2002, the departure controller stated he asked the pilot if he had received a 090 heading because he wanted to verify the heading clearance without berating the pilot on the frequency, and he wanted to bring the heading discrepancy to the pilot's attention. The departure controller stated that he believed the pilot was OK, based upon the pilot's reply.

At 1357:25, the airplane began a right turn from a 105 heading and traveled in an arc back toward the Dekalb-Peachtree Airport and VOR. At 1357:52, the departure controller began briefing a relief controller who was to assume the departure controller's duties. The departure controller stated to the relief controller, "four one zero five whiskey is supposed to be on a ninety heading climbing to four, still looks like he's heading south." The departure controller then contacted the pilot, "four one zero five whiskey, say your heading."

At 1358:13, the pilot replied, "zero five whiskey, two four zero." Radar data at the time of the pilot's reply showed the airplane on a 243 degree heading as it continued in a constant-rate right turn toward the Dekalb-Peachtree Airport and VOR. The departure controller replied, "alright, you're supposed to be heading zero niner zero." The pilot replied, "Alright, zero five whiskey, is that right to zero nine zero?" At 1358:25, the departure controller instructed the pilot to turn left to 090 degrees, and the pilot replied. The departure controller stated he observed N4105W begin the left turn and start leveling off at 4,000 feet. The departure controller then resumed briefing the relief controller with the status of three other aircraft being handled. The departure controller made no further communications with any aircraft, and the relief controller assumed the departure controller's duties. In an interview conducted on February 26, 2002, the departure controller stated he did not believe the pilot was in danger, because the pilot could maintain altitude, and the pilot never sounded unsure of himself or under stress.

At 1358:24, the satellite handoff controller contacted the Dekalb-Peachtree local controller and stated, "remember that zero five whiskey that departed two airplanes ago? ... Did he look like he knew what was going on?" The local controller responded, "He seemed fine." At 1358:51, the satellite handoff controller stated, "... I think we're just going to kind of watch him for a minute here."

Between 1359:16 and 1400:07, radar data showed the airplane flying in a level left turn at 4,000 feet to a heading of about 060 degrees, the magnetic heading was fluctuating from 045 to 074 degrees.

At 1400:11, radar data showed N4105W began a right turn. At 1400:48, radar data showed the airplane descended to 3,500 feet. At 1400:53, the relief controller stated, "november zero five whiskey, you want to inform me about what you're trying to do?" The pilot replied, "zero five whiskey, trying to get out of a spin." The relief controller asked, "trying to get out of where?" At 1401:01, the pilot said, "got a problem here." No further transmissions were recorded from the pilot. At 1401:46, the last recorded radar data showed the airplane in a right spiral pattern with at an altitude of 2,200 feet. The relief controller stated the pilot sounded calm and in control. The relief controller said, after the pilot reported a spin, the controller chose not to say anything else, because he believed the pilot needed to concentrate on flying.

Several witnesses on the ground observed the airplane cross interstate 85 below the clouds at what appeared to be a wings-level, nose-low attitude, then it turned sharply to the right and collided with trees in a steep nose-low, right wing-low attitude.
