Factors in this accident were: level three and four thunderstorms, intense to extreme precipitation, and severe turbulence. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight encounter with weather, cruise - flight into known adverse weather - continued, pilot in command (cause) - weather condition - thunderstorm (contributing factor) - weather condition - turbulence(thunderstorms) (contributing factor) - Loss of control - in flight, maneuvering - Airframe/component/system failure/malfunction, descent - uncontrolled - wing - overload - wing - separation - flight control,ruddervator - overload - flight control,ruddervator - separation - In flight collision with terrain/water, descent - uncontrolled ## Analysis The pilot was briefed that thunderstorms were developing along his planned route of flight, and were forecast to become 'severe.' In addition, he received a hazardous weather information alert (HIWAS), with hail, wind gusts to 70 knots, and cloud tops to 55,000 feet. The pilot contacted ATC and expressed his concern about the weather on his route of flight. ATC cleared him to deviate around the weather. While deviating around the weather, the pilot said to the controller, '...I'm into a cell here I think I need to get down...Bonanza one zero two alpha I need to go down.' The pilot was cleared to descend to 5,000 feet, and 1 minute and 2 seconds after being cleared to descend, the pilot said to the controller, 'I'm in a pretty bad cell I need help, over.' Radar and radio communication with the flight was lost and never reestablished. The last recorded radar return showed the airplane at an altitude of 6,700 feet, heading in a northeasterly direction. Before the airplane impacted the ground, a witness said he heard an airplane 'in a steep descent, straight down dive,' and the engine was running until he heard a 'loud boom.' The witness said, the weather at the time was 'lightning, thunder, and strong winds.' The left wing and tail stabilizer had separated from the airframe prior to impact . A weather study revealed that at the time of the accident the airplane had progressed into an area of strong thunderstorm activity with cloud tops of about 42,000 to 43,000 feet, with a level three to level four thunderstorm within 0.25 nautical mile of the flight, and a level four thunderstorm within 0.5 nautical mile. In addition, the thunderstorms contained intense to extreme precipitation, severe to extreme turbulence, and hail. ## Factual narrative HISTORY OF FLIGHT On April 29, 1996, about 1211 eastern daylight time, a Beech V35, N102A, registered to a private owner, operating as a Title 14 CFR Part 91, personal flight, had an in-flight separation and crashed near Powelton, Georgia. Instrument meteorological conditions prevailed and a IFR flight plan was filed. The airplane was destroyed. The commercial pilot, and one passenger were fatally injured. At 0911:29, the pilot of N102A called the Anniston, Alabama, Automated Flight Service Station (ANB AFSS), and obtained a standard pilot weather briefing for an IFR flight from Greenville, Alabama to Aiken, South Carolina. The pilot indicated to the AFSS specialist that he planned to depart around 1000 local time and was given the following weather information: "...[Montgomery] forcecasted ceilings five hundred broken, four [visibility in miles], fog and haze, with occasionally five hundred scattered twenty-five thousand scattered visibilities six...out of Alabama...they're calling for...marginal conditions with ceilings fifteen hundred to twenty-five hundred, scattered to broken and maybe three to five thousand overcast, with widely scattered thunderstorm rain showers. You're beginning to get quite a bit of thunderstorm and rain shower activity uh it's trying to form a line from Charlotte, North Carolina, over around Augusta, Georgia, down towards Macon and on down to Tallahassee...that's not solid it's V F R through there right now...that's widely scattered...but all of this has developed within the last...hour and a half...another couple of hours...it could be uh form a line from about...twenty [to] twenty-five miles south of Macon, Georgia." In addition, the pilot was briefed that depending on how the line of storms developed, around 1200, the storms were forecasted to become "severe." The briefer advised the pilot that there were "no NOTAMS" (notice to airmen) for Aiken. The pilot filed his IFR flight plan and stated that he would call again to check for weather up dates. The phone conversation ended at 0919:52, and the pilot did not call the AFSS again. The flight departed Greenville, Alabama, about 1100, the pilot reported in on the Atlanta, Sector 13, radio frequency, and requested IFR clearance. The Sector 13 Radar Specialist (R13) issued a beacon code, advised the pilot he was in radar contact, and issued the IFR clearance to Aiken, via direct Montgomery, to climb and maintain 7,000 feet. Between 1102:35, and 1144, the flight was handed off to several different sectors, until the pilot established radio communication with Macon Approach Control (MCN RAPCON), at 1144:18. At 1147:17, Macon High Radar (MHI), issued a hazardous weather information alert (HIWAS), to all aircraft, as follows: "...for severe thunderstorms for Georgia, South Carolina, 75 statute miles...west of a line from 55 miles east of Macon to 30 east northeast of Spartanburg to 65 miles northwest-to 55 nautical miles east and west of a line, 47 east of Macon to 28 west southwest [of] Charlotte. Hail surface and aloft, two and a half inches, wind gusts, 70 knots maximum, tops 55,000 [feet], wind vector, two two zero [220 degrees] at three zero." The pilot of N102A contacted the MHI controller, at 1201:14, and asked, "are you painting any weather at my twelve o'clock [position]...." The controller replied; "...that's the weather area the other controller read you on the um convective SIGMET [significant meteorological information] activity, it extends um at least from your twelve o'clock, going counter clockwise now over to your twelve o'clock-ones at your twelve o'clock position about 20 miles, that's the extent of my radar coverage. I can't see any further than the MISTY intersection...if you need to go around the north side, if you want to deviate around, that's approved." The pilot answered that, "...we're not in the clouds right now, we got pretty good visibility, but uh it looks like we're right on the edge of it...." At 1203:08, the control gave the pilot the details pertaining to convective SIGMET No.9, the pilot thanked him, and asked, after receiving the information, the SIGMET's location as it applied to Macon. The pilot stated "that puts Augusta right in the middle of it then," and the controller told him that "would be my guess...you'll be talking to Augusta Approach here in uh about 15 miles." The pilot answered at 1203:58, "...so far I'm okay we'll just keep watching this stuff and make sure we don't stumble into anything." The pilot asked to go "direct Colliers rather then direct Aiken, just to sorta stay on the edge of this," and the controller approved the request. Macon Approach coordinated the deviation with Atlanta ARTCC (Air Route Traffic Control Center, ZTL Sector 17, R17), and communications with the pilot was transferred. At 1206, the pilot of N102A reported on frequency at an altitude of 7,000 feet, and was told when he was able to, proceed direct to Augusta. The pilot said to the R17 controller, at 1206:43, "...I'd like a little help here, if you can help me, it looks like I got it pretty clear at Colliers, but uh I don't want to run into anything...." The controller asked him what altitude he would like, and the pilot answered, "I'm okay at seven (7,000) right now." The controller told him if he would like a lower altitude to just let him know. At 1207:02, the pilot said, "...I'm more concerned about...any weather you're painting up that way. I don't see anything from here it looks relatively clear...." The R17 controller answered, "...all we're able...to uh display is precipitation, and in that area it looks like there are possibly some heavy precipitation beginning at about 10 miles extending uh at least 20 miles, beyond that I'm not able to give you accurate description due to uh limited coverage in that area on our radar. Augusta approach will have a better...description of that here in a moment." There was a controller change at 1209:20, and N102A was pointed out in the controller briefing to the next controller. At 1210:07, the pilot of N102A said to the R17 controller, "...I'm into a cell here I think I need to get down, over...Atlanta Center, Bonanza one zero two alpha I need to go down." The controller attempted to coordinate the clearance with other sectors, and at 1210:33 the pilot asked the controller "do you read me." The pilot was cleared to descend to 5,000 feet, and he acknowledge by saying "thank you very much." The last recorded radar return at 1211:04, showed the airplane at an altitude of 6,700 feet, heading in a northeasterly direction. At 1211:09, the pilot of N102A said to the R17 controller, "I'm in a pretty bad cell I need help, over." The R17 controller said "say again...calling center say again." At 1211:25, an unknown transmission was heard on the frequency saying, "yeah it's that Bonanza, sounds like he's in trouble." Radar and radio communication with the flight was never reestablished. Several attempts were made to reestablish communications with the pilot of N102A before a search was started. At 1600, a helicopter located the wreckage in a heavily wooded area. A witness standing on his back porch about 2 miles from the crash site said he heard what in his opinion sounded like an airplane "in a steep descent, straight down dive." The witness heard the engine running until he heard a "loud boom," which he felt was the airplane impacting the ground. The witness said that the weather at the time was "lightning, thunder, and strong winds." The accident occurred during the hours of daylight approximately 33 degrees, 24 minutes north, and 82 degrees, 51 minutes west.
