New Jersey

Aircraft was substantially damaged when it veered off the runway while landing at Hammonton Municipal Airport (N81), Hammonton, New Jersey. The private pilot was not injured and the commercial pilot-rated passenger received minor injuries. Visual meteorological conditions prevailed, and an instrument flight rules flight plan was filed for the flight. The flight originated from Montgomery County Airpark (GAI), Gaithersburg, Maryland about 1105 and was destined for N81. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. The airplane was being repositioned to N81 in order for the owner's insurance adjuster and a local mechanic to physically inspect previous claim work for damage done during ground handling following Hurricane Sandy. The pilot reported lowering the landing gear during the approach to runway 03, and confirmed that they were extended by observing the landing gear position indicator lights. Immediately after touchdown, the airplane veered to the left. The pilot applied full right rudder, but the airplane continued to veer to the left. After departing the left side of the runway, the airplane struck several trees and was subsequently engulfed in a post-crash fire. According to FAA records, the pilot held a private certificate, with ratings for airplane single- and multiengine land. His most recent FAA third class medical certificate was issued on January 2, 2013. As of April 5, 2013, the pilot reported a total of 587 total hours of flight experience, of which 120 hours were in the same make and model as the accident airplane. The seven-seat, twin-engine, low-wing, retractable tricycle-gear airplane was manufactured in 1977 and was equipped with two Continental Motors TSIO-520, 520-hp engines. Review of the airplane's maintenance logbooks revealed that its most recent annual inspection was completed on October 26, 2012. At the time of inspection, the airplane had accumulated 9,335 total hours in service. The number one and two engines accumulated approximately 735 and 157 total hours of operation since overhaul, respectively. The airplane had flown about three hours since the most recent annual inspection. The 1154 recorded weather observation at Atlantic City International Airport (ACY), Atlantic City, New Jersey, located about 15 miles southeast of the accident site, included wind from 330 degrees at 13 knots, 10 miles visibility, few clouds at 1,600 feet, temperature 11 degrees C, dew point 4 degrees C, and a barometric altimeter setting of 29.83 inches of mercury. N81 was a non-tower-controlled airport equipped with one asphalt runway, oriented in a 03/21 configuration. The runway was 3,601 feet in length and 75 feet wide. The field elevation for the airport was 65 feet mean sea level.

Although the pilot filed an instrument flight rules flight plan through the Direct User Access Terminal System (DUATS), no evidence of a weather briefing was found. The flight departed in visual meteorological conditions and entered instrument meteorological conditions while climbing through 12,800 feet. The air traffic controller advised the pilot of moderate rime icing from 15,000 feet through 17,000 feet, with light rime ice at 14,000 feet. The controller asked the pilot to advise him if the icing worsened, and the pilot responded that he would let them know and that it was no problem for him. The controller informed the pilot that he was coordinating for a higher altitude. The pilot confirmed that, while at 16,800 feet, "…light icing has been present for a little while and a higher altitude would be great." About 15 seconds later, the pilot stated that he was getting a little rattle and requested a higher altitude as soon as possible. About 25 seconds after that, the flight was cleared to flight level 200, and the pilot acknowledged. About one minute later, the airplane reached a peak altitude of 17,800 feet before turning sharply to the left and entering a descent. While descending through 17,400 feet, the pilot stated, "and N731CA's declaring…" No subsequent transmissions were received from the flight. The airplane impacted the paved surfaces and a wooded median on an interstate highway. A postaccident fire resulted. The outboard section of the right wing and several sections of the empennage, including the horizontal stabilizer, elevator, and rudder, were found about 1/4 mile southwest of the fuselage, in a residential area. Witnesses reported seeing pieces of the airplane separating during flight and the airplane in a rapid descent. Examination of the wreckage revealed that the outboard section of the right wing separated in flight, at a relatively low altitude, and then struck and severed portions of the empennage. There was no evidence of a preexisting mechanical anomaly that would have precluded normal operation of the airframe or engine. An examination of weather information revealed that numerous pilots reported icing conditions in the general area before and after the accident. At least three flight crews considered the icing "severe." Although severe icing was not forecasted, an Airmen's Meteorological Information (AIRMET) advisory included moderate icing at altitudes at which the accident pilot was flying. The pilot operating handbook warned that the airplane was not certificated for flight in severe icing conditions and that, if encountered, the pilot must exit severe icing immediately by changing altitude or routing. Although the pilot was coordinating for a higher altitude with the air traffic controller at the time of the icing encounter, it is likely that he either did not know the severity of the icing or he was reluctant to exercise his command authority in order to immediately exit the icing conditions.
