New York

The purpose of the flight was for the flight instructor to provide multiengine airplane training, in a late 1930's vintage amphibious airplane, to his brother, a single engine airplane rated private pilot. No published performance data was available for the airplane, and according to the flight instructor, much of what he knew about the performance of the airplane he learned from previous flights. Just after takeoff on the accident flight, and about 600 feet above ground level (agl), and as the pilot was retracting the landing gear and starting a left turn to the crosswind leg of the traffic pattern, the flight instructor retarded the right throttle in order to simulate a failure of the right engine. The pilot executed the procedures for an in-flight engine failure and the instructor looked out of the window to check for traffic in the airport traffic pattern. The flight instructor then heard the pilot state "I am at blue line but losing altitude." The flight instructor continued to scan for traffic and moved the right throttle forward to about the "half throttle" position. The pilot could not recall if he had adjusted either of the power controls after the initial application of power for takeoff. The airplane continued to descend, impacted the ground, and caught fire.

The airplane departed from a maintenance facility, after installation of the right engine, with an unknown quantity of fuel. Shortly after takeoff, the pilot reported that he had "lost" an engine. He requested vectors for the departure airport, then amended his request to an alternate destination. From the original distress call to the last recorded radar target, approximately 2 ½ minutes, the airplane descended from 2,500 feet to 700 feet and slowed from 190 knots to about 87 knots. Several witnesses described the engine sound as "rough", and "cutting in and out" before the airplane descended out of view and sounds of impact were heard. The left wing was consumed by post-crash fire. Forty gallons of fuel were drained from the right inboard and nacelle tanks. Only trace amounts of fuel were visible in the right outboard tank. Both fuel selectors were found in the outboard tank position. Examination of flight times and ground-maintenance run times revealed that the engines were run for approximately 3 hours with the outboard tanks selected. The outboard tanks each held 40 gallons, for a total of 80 gallons. According to the pilot's operating manual, the fuel consumption rate at the maximum endurance power setting was 28 gallons per hour.

The airplane, which was not operating on a flight plan, was proceeding in clear skies to an airport where the passenger was joining his wife. After crossing a lake near the destination, the airplane flew over rising terrain, along a saddleback, until it struck a stand of old-growth trees that jutted above new-growth trees. During the last 48 seconds of radar coverage, the airplane climbed 600 feet with no erratic course deviations. From the accident location, the airport would have been about 5 nautical miles off the airplane's right wing. The pilot had 32,000 hours of flight experience. The passenger was under investigation for fraud, and attempted to obtain life insurance prior to the flight. The passenger had also loaned money to the pilot, and was receiving "flight services" in lieu of cash payment when the pilot failed to pay back the loan. A .380 caliber pistol magazine was found at the accident site with two rounds of ammunition missing; however, no weapon was located at the site, and no weapon of that caliber was known to be associated with either the pilot or the passenger. Premature ventricular complexes (PVCs) were found on electrocardiograms performed in conjunction with the pilot's airman medical certificate applications in 2002 and 2004. The pilot's autopsy report indicated "severe calcific... coronary disease, with 90 percent narrowing of the left anterior descending coronary artery and 75 percent narrowing of the right coronary artery." Cause of death, for both the pilot and passenger, was listed as "undetermined." The autopsy reports also noted that, "due to the inability to perform a complete autopsy...of either of the two aircraft occupants, it cannot be determined whether either the pilot or the passenger were alive or dead at the time of the crash." Post accident inspection of the airplane disclosed no evidence of any preimpact anomalies.

The copilot was flying an ILS approach at an airspeed of Vref plus 10 knots, and the captain made visual contact with the runway about 350 feet agl. The airplane then drifted high on the glideslope, and the copilot decreased engine power. The sink rate subsequently became too great. By the time the captain called for a go-around, the airspeed had deteriorated, and the stick shaker activated. Although power was applied for the go-around, the airplane impacted the runway in a level attitude before the engines spooled up. The airplane came to rest in snow, about 20 feet off the left side of the runway, near mid-field.

The commercial pilot/owner was on a cross-country flight from Orlando, Florida, to Salisbury, Maryland, on an instrument flight rules (IFR) flight plan. The pilot stated that all five fuel tanks were topped off and verified as full before departure. The fueler, in a written statement, reported that he added 100 gallons of fuel and that the fuel tank levels were topped off. In addition to the main tanks, the airplane was equipped with two large-capacity auxiliary tanks (31.5 gallons of useable fuel each) and a locker tank, and the airplane's total useable fuel capacity was 183 gallons. As the airplane approached Maryland, the pilot requested weather for White Plains, New York (HPN) and then changed his destination to HPN. As he approached the New York area at 21,000 feet, air traffic control (ATC) instructed the pilot to fly a published arrival procedure and to maintain an altitude of 16,000 feet. The pilot stated that, due to poor weather and air traffic congestion, he became concerned about possible delays and informed ATC that he had "minimal fuel." He did not declare an emergency. ATC then issued the pilot a descent clearance, and he reduced both throttles to idle. In preparation to level off at the new altitude, the pilot increased power on both throttles, and the right engine stopped producing power. The pilot was unable to maintain the assigned altitude and told the controller that he had "lost an engine, and needed vectors to the nearest runway." The left engine stopped producing power about 2 minutes later. The pilot ditched the airplane and exited the airplane before it sank. The airplane was not recovered. The pilot reported that there were no mechanical problems with the airplane before the flight.
