Accident Details
On September 6, 2012, about 1135 eastern daylight time, a Beech 76, registration N6716L, was substantially damaged following a loss of directional control while landing at Central Jersey Regional Airport (47N), Manville, New Jersey. The private pilot and a pilot-rated passenger sustained serious injuries. The airplane was registered to N6716 LLC and operated by the pilot under 14 CFR Part 91 as a personal flight. Visual meteorological conditions prevailed, and no flight plan was filed. The flight originated at Princeton, New Jersey (39N) at 1030.
Pilot and Passenger Accounts
The pilot reported that he was acting as pilot-in-command during the approach to runway 25 and occupied the left cockpit seat. Following a normal approach, the airplane touched down and began to drift left. He commenced a go-around about the same time that the passenger called out “full power.” The pilot applied full power, the airplane accelerated, and began to lift off. The airplane then began to turn and roll to the right. As he applied flight control inputs to correct the situation, the airplane rolled to the left and ultimately struck the ground.
The passenger reported that during the approach to runway 25, he had the right cockpit seat positioned aft and was looking at his iPad. There was no wind or other weather issues. The pilot flew a normal approach; however, he “did not touch down early enough.” The airplane “porpoised” back into the air after departing the left side of the runway. He advised the pilot to go around, and the pilot added full power. The airplane gained altitude and pitched hard to the right. The passenger stated that at no time during the flight were simulated single engine procedures practiced.
Witness Account
A witness on the ramp, who was a flight instructor, reported that the airplane was stabilized on final approach to runway 25 and the propellers were turning. The airplane touched down in the first third of the runway, bounced slightly, and then the pilot added power. When power was added, the airplane banked heavily to the right and reached an altitude of about 20 to 30 feet above the runway. He heard the power come back to idle and then the airplane banked to the left. The left wing then struck a dirt mound off the left side of the taxiway, the airplane struck a fence, and flipped over on its back. While airborne, he did not observe any visual indications of an engine failure and the propellers were not feathered.
Post-Accident Examination
A Federal Aviation Administration inspector responded to the accident site and examined the wreckage. Substantial damage to the wings, fuselage, and empennage was confirmed. The inspector reported that the right engine “did not appear to be operating.” The right mixture control was found in the idle cutoff position. Fuel was found in both wing tanks. The fuel selector valves tested normally in the “on” position.
The wreckage was recovered to a storage facility where a subsequent examination was performed on March 20, 2013, by an NTSB Air Safety Investigator and an FAA Airworthiness Inspector. Examination of the right engine propeller blades revealed leading edge gouges and a broken blade tip. Compression was noted on all six cylinders, and valve train continuity was confirmed when the engine was rotated manually. The right magneto produced spark to all leads except the number one cylinder bottom plug. The top spark plugs exhibited normal wear and color. The carburetor inlet screen showed no contaminants; the carburetor bowl contained fuel with no contaminants. The right engine oil sump screen had no particulates.
