A factor was the thunderstorm activity. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight encounter with weather, cruise - normal - flight into adverse weather, pilot in command (cause) - weather condition - thunderstorm (contributing factor) - in-flight planning/decision - inadequate, pilot in command (cause) - Loss of control - in flight, maneuvering - aircraft control - not maintained, pilot in command (cause) - Airframe/component/system failure/malfunction, descent - uncontrolled - flight control surfaces/attachments - overload ## Analysis The aircraft was at cruise flight at 11,000 feet with an instrument rated private pilot and passenger aboard. Thunderstorms and convective activity were in the area. The pilot elected to continue toward the weather, and requested to deviate around it, but did not specify a direction. After receiving permission for the deviation, the airplane first turned left while maintaining altitude, and then turned right greater than 90 degrees, and descended. The last radar contact was at 9,300 feet, after which radio and radar contact was lost. Witnesses on the ground observed the airplane in a descent estimated to be between 30 and 45 degrees nose down, below the base of the clouds, and could hear the engine operating. The witnesses observed the airplane come apart, while operating clear of clouds. One witness reported the descent started to shallow just prior to the airplane coming apart. The debris trail to the impact crater was 1,033 feet long, and it extended an additional 486 feet beyond the impact crater. The horizontal stabilizer and wings had downward bending on their spars. One propeller blade was found in the main impact crater, separated from the propeller hub, with "S" bending on the leading and trailing edges of the blade. ## Factual narrative HISTORY OF FLIGHT On May 30, 2002, about 1850 eastern daylight time, a Cessna A185F, N1577B, was destroyed when it impacted terrain in Pleasant Mount, Pennsylvania. The certificated private pilot, a passenger, and a dog were fatally injured. Visual meteorological conditions prevailed for the business flight that originated from DeKalb County Airport (07C), Auburn, Indiana. The flight was conducted on an instrument flight rules (IFR) flight plan under 14 CFR Part 91. On May 27, 2002, the pilot initiated a trip from a private airstrip on his property, Flying Ridge Airstrip (CT52), Newtown, Connecticut. He flew to Naper Aero Club Airport (LL10), Naperville, Illinois, on business. On May 30, 2002, the pilot initiated a return trip. At 1152 (1552 UTC), the pilot contacted the Federal Aviation Administration (FAA), Kankakee Flight Service Station, Kankahee, Illinois, for a pre-departure weather briefing. The pilot reported that he could fly either under instrument flight rules, or visual flight rules. He also reported that he was going to make an en route stop near Fort Wayne Indiana. The pilot was advised of an area of convective activity, with tops of FL 330 (33,000 feet). The system ran from Akron, Ohio, and Youngstown, Ohio, to north of Pittsburgh, Pennsylvania. Isolated rain showers were reported. Convective activity was reported south of Youngstown, with tops to 34,000 feet, and about 40 miles north of Pittsburgh. The weather system was moving eastward. The pilot did not receive any further weather briefings. The pilot then departed Naperville, en route to Auburn. At Auburn, the airplane was serviced with 67.2 gallons of 100 low lead aviation grade gasoline. The pilot departed Auburn under visual flight rule, about 1445 central daylight time (1545 eastern daylight time). After departure from Auburn, the pilot contacted air traffic control and requested to air-file an IFR flight plan to Oxford, Connecticut. The airplane was at 13,000 feet when control was transferred from the Cleveland Air Route Traffic Control Center (ARTCC) to the New York ARTCC. About 1836, the airplane was descended to 11,000 feet at the pilot's request. About 1846, control of the airplane was transferred to the Boston ARTCC. At 1848:52, the pilot requested to deviate around weather. The request was approved, and the controller advised the pilot to report when the airplane was back on course. No further transmissions were received from the pilot, and the airplane disappeared from the controller's radarscope. Four witnesses in the Pleasant Mount area, observed the airplane, descending in a nose down attitude, traveling to the northwest. Some of the witnesses could hear the engine running, and agreed that the airplane was traveling fast. The witnesses observed the airplane come apart in the air, while descending below the base of the clouds. The descent angle as reported by the witnesses, varied between 30 and 45 degrees nose down. One of the witnesses reported hearing wind noise in addition to the engine noise. All of the witnesses agreed there were clouds and weather in the area. One reported a dark sky with thunder, while the others reported no violent weather at their location. In addition, none of the witnesses reported any smoke, vapors, or fire emitting from the airplane. One witness reported that the dive the airplane was in, appeared to shallow just prior to the airplane coming apart. The accident occurred during the hours of daylight at 41 degrees, 43.408 minutes north latitude, and 75 degrees, 18.767 minutes west longitude. PERSONNEL INFORMATION According to records from the FAA, the pilot held single and multi-engine land, and single and multi-engine sea ratings, and an instrument airplane rating. On his last FAA airman medical application, dated January 19, 2001, he listed his total flight experience as 6,800 hours, with 150 hours in the preceding 6 months. The pilot's logbook was not recovered, and the pilot's recency of experience and date of last flight review was not determined. In addition to the accident airplane, which the pilot had access to, the pilot also owned another airplane. The pilot was also reported to have taken a three-week trip to the Dominican Republic in April 2002. The pilot was estimated to have accumulated about 300 hours since his last FAA airman medical application for a total flight experience of about 7,100 hours, including about 50 hours in the 2 1/2 months that preceded the accident. The FAA had filed a violation against the pilot, and the pilot had accepted a 180-day suspension to settle the occurrence. The suspension, which began on November 27, 2001, was divided into two sections. The pilot's certificate was returned to him on March 13, 2002. According to a letter from the FAA, the pilot was supposed to surrender his pilot certificate again, not later than May 12, 2002, to serve out the remainder of his suspension. The FAA reported that they had not received the pilot's certificate. The passenger did not posses a pilot certificate or FAA airman medical certificate. However, the pilot's brother reported that the pilot had been teaching the passenger how to fly the airplane, and perform simple maneuvers. The level of proficiency attained by the passenger was not determined. AIRCRAFT INFORMATION The airplane was a 1976 Cessna A185F. It was equipped with functioning dual flight controls. The engine power controls were located between the two pilot seats, on the lower instrument panel. The airplane had been modified with several supplemental type certificates (STC), which included the installation of a larger engine, and various high lift devices to enhance slow flight capability on the airplane. These modifications included the addition of vortex generators on both the underside of the horizontal stabilizer, and the tops of the wings. According to the Pilot's Operating Handbook for the 1976 Cessna 185 Skywagon, the never exceed speed Vne was 182 KIAS (knots indicated airspeed); the maximum structural cruising speed was 146 KIAS; the maneuvering speed Va was 118 KIAS at 3,350 pounds; 105 KIAS at 2,650 pounds, and 90 KIAS at 1,950 pounds. The airplane was issued a dual airworthiness certificate. This allowed the airplane to be flown in the normal category when not being used for aerial photography. To accommodate the aerial photography equipment, the rear seat had been removed from the airplane. However, no cameras were installed in the airplane at the time of the accident. The tachometer was not identified in the wreckage. The last annual inspection occurred on July 16, 2001, at a total airframe time of 4,470.4 hours. The airplane was estimated to have accumulated about 100 additional hours since the last annual inspection. METEOROLOGICAL INFORMATION A straight line from Auburn to Oxford, penetrated the line of weather the pilot had been briefed on, at 1152. The weather extended for over 60 nm north and south of the line between Auburn and Oxford. According to the NEXRAD radar from Binghamton, New York, at 1808, and 1903, there was line of thunderstorms, orientated northeast/southwest moving eastward through the area. The area to the northeast and southwest of the accident were more intense than the area near the accident site. Some of the witnesses reported hearing thunder and seeing dark skies nearby to the accident site. However, none of the witnesses reported rain at the time of the accident. The 1854, weather observation at Wilkes-Barre/Scranton International Airport (AVP), Wilkes-Barre/Scranton, Pennsylvania, located 30 nautical from the accident site on a magnetic heading of 231 degrees, recorded a ceiling of 5,000 feet overcast, visibility 10 statue miles, and winds from 210 degrees, at 4 knots. In addition, two convective SIGMETS (significant meteorological information) 97E and 98E were issued.
