NTSB Factual Report

HISTORY OF FLIGHT

On January 1, 2004, at 1004 central standard time, a Bellanca 17-30A single-engine airplane, N4104B, registered to and operated by the pilot, was destroyed when it impacted residential structures shortly after takeoff from Addison Airport (ADS), near Dallas, Texas. The instrument rated private pilot and his passenger sustained fatal injuries. Instrument meteorological conditions (IMC) prevailed and an instrument flight rules (IFR) flight plan was filed for the personal flight conducted under the provisions of Title 14 Code of Federal Regulations Part 9. The planned 277-nautical miles cross-country flight was destined for Amarillo International Airport (AMA) near Amarillo, Texas.

According to air traffic control (ATC) data provided by the Federal Aviation Administration (FAA), the pilot was issued a clearance to AMA at 0945 via the Kingdom Five standard departure; however, the pilot was unclear about the instructions. The controller then re-explained the instructions, and the pilot read back the clearance correctly. At 0948, the pilot advised the tower that he had the Kingdom Four departure, not the Kingdom Five departure. The controller then re-read the clearance to the pilot again, and the pilot seemed confused about the radials. The controller re-read the radial information again, and the pilot stated, "I got it and am ready for takeoff." At 0952, the controller contacted regional departure and advised them to watch N4104B, since the pilot had trouble with his departure clearance. At 0956, the tower advised the pilot to contact regional departure, and the pilot acknowledged. The airplane departed ADS from runway 15 at 0957.

After the aircraft departed ADS, the departure controller informed the pilot that he had lost the transponder beacon, and requested that the pilot recycle his transponder. At 0958, the departure controller advised the pilot that he had the transponder beacon again. At 1001:01, the pilot was instructed to turn right to a heading of 270 degrees. The pilot acknowledged and reported "....gyro has out gone out so I'm on partial panels." The departure controller advised the pilot that it looked like he was making a left turn, and instructed him to turn right. The pilot acknowledged. The controller advised ATC at Dallas Love Field (DAL) that he thought the pilot was disorientated because "he's doing left turns instead of right turns like he's suppose to be so watch out for him." At 1001:59, the pilot advised ATC that he was "gonna go ahead and ease it around to the right till I get to two forty degrees." At 1002:07, the pilot stated, "I'm getting ah starting to get oriented to the partial panel here." There were no further communications with N4104B, and radar contact was lost.

The airplane impacted a private residence on a northeasterly heading, slid across a residential street, and impacted two vehicles in the garage of a second private residence. The airplane and both residences were destroyed by post-impact fire. There were no reported ground injuries.

Details of the approximate last minute radar data follow. All times are given in central standard time (CST). Altitudes are given in feet above mean sea level (msl).

The last discernable radar return was approximately 32 degrees, 53 minutes north latitude, and 096 degrees, 46 minutes west latitude, and at an unknown altitude, on a heading of 091 degrees and 148 knots.

Eight witnesses in the vicinity of the accident site who either heard or observed the airplane prior to impact, where interviewed by or provided written statements to the NTSB investigator-in-charge. The witnesses (by number) are depicted on a diagram showing their respective locations relative to the accident site. The diagram is attached to this report.

Witness #1, a frequent "plane watcher" and private pilot, provided a written statement to the NTSB investigator-in-charge (IIC). The witness stated that his house, located 2.11 miles west of the accident site, is almost under the Runway 33 approach path into ADS and the downwind leg to DAL, so airplanes flying above his house was normal. Just before 1000, he heard an aircraft with a high performance engine fly over or near his home at an altitude that "seemed" to be lower than normal; since the sound was louder than normal. Several seconds later, he heard the airplane fly over or near the house again. He went out into the backyard to see if he could see the airplane, but couldn't because of the low ceiling and limited visibility. He thought the airplane might be circling and remembered wondering why he would be doing that at a low altitude and in that weather. As the noise seemed to lessen, he heard another plane's engine and thought the first plane could possibly be maneuvering for sequencing into ADS. Several seconds later, while still in the backyard, he heard the first plane a third time, as loudly as the first and second times. The engine seemed to be running at high RPM's, but smoothly. It sounded like the airplane was again maneuvering, or circling. The witness stated that he remembered thinking the pilot must be lost. The sound seemed to fade slightly, and then it came back as loud as ever. The witness remembered thinking that the plane sounded like it was pulling out of a loop or similar high-speed maneuver. The sound, clearly coming from the east, got louder and louder, then abruptly stopped with a faint "pop, pop" sound. The witness stated again that the airplane "clearly" came over or near his house three separate times, and the engine "seemed" to be running smoothly each time.

Witness#2, located approximately .5 miles west of the accident site was interviewed by the IIC and reported observing the airplane flying overhead in an straight and level attitude approximately 125 feet above ground level (agl), slightly below the layer of clouds.

Witness#3, who resided approximately .2 miles west of the accident site, stated that she had stepped outside and was standing on the back patio, when she "heard the loud noise of a small plane going full throttle - racing, full speed overhead." She looked up but could not see anything, even though from the noise, the airplane sounded low. She heard two "popping noises - like a car backfiring." Then not hearing anything else, she stepped back inside her house. After a few minutes, she returned outside, in front of her house. When she looked to the east, she saw flames coming from the end of the block, on the north side of the street. She stated that she never heard what she would recognize as an explosion, a "boom" sound, nor was she aware of any shaking of her house. Walking back inside her house, she observed a sizeable piece of glass in the middle of her neighbor's front yard.

Witness #'s 4 and 5, who resided approximately .2 miles west of the accident site, reported hearing the sound of an engine pass overhead, at a low altitude, followed by a "loud boom." The impact was "hard enough to rattle windows." The witnesses reported hearing the noise, but it was too "cloudy" to see anything.

Witness #6, was located approximately 80 yards north of the accident site. At the time of the accident, he was jogging towards the location of the accident, and reported hearing the airplane's engine "humming." He saw the airplane strike the first house eastbound. The witness stated that he saw the fire "stretch" from the house on Currin (the impact point), 20-25 yards north of Currin, across St. Judes. He saw parts of the airplane cross St. Judes into the 7100 block of Currin, the north side. The witness observed the fire engulf the house west of St. Judes, on the north side of Currin, and observed smoke engulf the house located on the eastside of St. Judes, the north side of Currin.

Witness #7 was interviewed and provided a statement to the IIC. At the time of the accident, she was inside her house, located across the street from the accident site, and heard a "cranking" noise. She observed smoke coming from the tail section of the airplane prior to impact. Due to the cloudy weather conditions, she could only see the tail section; however, stated that she heard a "bang."

Witness #8, a private pilot, resided approximately .58 of a mile northeast of the accident site, and was outside of his house at the time of the accident. He stated that he heard an airplane engine that sounded "normal." After about 15 seconds, it sounded as if the airplane was maneuvering, because of the pitch change in the engine. According to the witness, "it [the engine] still sounded like it was making good power." The airplane was rapidly getting closer and sounded very low and fast. Right before he heard the impact, the "engine was still at a very high power level and the airspeed sounded to be very high." This was followed by two impacts in rapid succession and he felt the percussion. The witness stated, "at no time did I see the aircraft due to the weather conditions. At no time did the engine sound seem to be faulty or cutting in or out."

PERSONNEL INFORMATION

The pilot held a private pilot certificate with airplane single-engine land and instrument airplane ratings. The pilot was issued his most recent third-class medical certificate on May 30, 2001, with limitations stated "must wear corrective lenses." At the time of his last medical application, the pilot reported to have accumulated a total of 1,050 hours. The pilot's personal flight logbooks were not recovered.

AIRCRAFT INFORMATION

The 1975 model Bellanca 17-30A, serial number 75-30776, was a single-engine, low-wing retractable landing gear monoplane with an all wood wing construction and a fabric covered steel-tube fuselage, configured for a maximum of four occupants. The airplane was powered by a Continental IO-520-K series engine (serial number 557201), rated at 300 horsepower, driving a three bladed Hartzell constant speed propeller (model HC-C3YF-1RF). The airplane was registered to the current owner on January 30, 1989.

The airframe and engine logbooks were damaged by post-impact fire. Review of the airframe logbooks revealed that an annual inspection of the airplane was completed on September 10, 2003, at a total airframe time of 2,104.5 hours. The exact total time of the airframe at the time of the accident could not be retrieved due to impact damage to the Hobbs meter and tachometer. The last airframe logbook entry on October 23, 2003, stated that new brushes in the landing gear motor were installed. The airframe total time as of this entry was 2,120 hours.

According to the engine logbook, the engine was overhauled on October 23, 1990, and had accumulated a total time of 562.5 hours since the major overhaul. An annual inspection of the engine was completed on September 10, 2003 at a total engine time of 2,104.5 hours.

METEOROLOGICAL INFORMATION

At 0028, the pilot contacted the Fort Worth Flight Service Station (AFSS), Fort Worth, Texas, and requested and received a standard weather briefing for a flight from ADS to AMA. The pilot filed an IFR flight plan for a 0730 departure the following morning from ADS direct to AMA, at an altitude of 4,000 feet msl.

At 0914, the pilot contacted Fort Worth AFSS and received a standard weather briefing for an IFR flight from ADS to AMA. The briefer informed the pilot that an AIRMET for icing conditions in the Wichita Falls area was in affect, and that a weather advisory was in affect for low IFR conditions in the vicinity of Waco, Texas. There were no notices to airmen (NOTAMs) issued. At this time, weather reported at ADS was wind from 130 degrees at 3 knots, visibility 7/8 in mist, with overcast skies at 200 feet. The temperature and dew point were reported as 15 degrees Celsius.

The automated surface observing station ADS at 0957 reported wind from 130 degrees at 6 knots, visibility 7/8 in mist, overcast at 100 feet. The temperature and dew point were reported as 17 degrees Celsius, and an altimeter setting of 30.20 inches of Mercury. The IIC calculated the pressure altitude at 386 feet and the density altitude at 775 feet.

NTSB Probable Cause

The failure of flight/navigation instruments while in instrument meteorological conditions (in-cloud flight and low ceilings) resulting in spatial disorientation. A contributing factors was the prevaling instrument meteorological conditions (low ceiling and in-cloud flight)
