Great Bend, KS, USA

Aircraft #1

N567CM

SCHRIEBER ROBERT L P 70

Analysis

The private pilot was conducting a local personal flight. An employee of the fixed-based operator reported that, before takeoff, the pilot topped off the airplane's 18-gallon fuel tank. A witness reported hearing the airplane approach his residence from the north about 2 hours later. The witness said he saw the airplane come out of a cloud bank and that it looked like it was trying to climb at a 45-degree angle. He subsequently saw it in a 45-degree, nose-down pitch angle descending toward the ground. The airplane impacted in a corn field located 6 miles north of pilot's home airport. The witness said the engine sounded "weak as if it had no power" and that, as the airplane was descending, the pilot "was trying to pull up."  An examination of the airplane at the accident site showed that the airplane impacted the ground in a nose-down, steep descent. Flight control continuity was confirmed. Both of the propeller blades were broken at the hub and showed no signs of driving power. An examination of the engine revealed no anomalies that would have prevented it from producing power.  The airplane's fuel tank could hold 18.06 gallons of fuel. The engine manufacturer estimated that the engine's fuel consumption rate at a normal power setting was between 10.5 and 11 gallons per hour; therefore, the airplane would have been able to fly for 1 hour 42 minutes. It is likely that the pilot did not properly plan for the flight, which was longer than allowed by the airplane's total fuel quantity and resulted in loss of engine power due to fuel exhaustion. During the subsequent forced landing to the field, the pilot lost airplane control.

Factual Information

HISTORY OF FLIGHTOn June 8, 2014, about 1130 central daylight time, a Robert L. Schrieber P70 Acey Deucy experimental amateur-built airplane, N567CM, owned and operated by Brining Air LLC and being flown by a private pilot, impacted terrain near Great Bend, Kansas. The private pilot and passenger on board sustained fatal injuries and the airplane was substantially damaged. The local, personal flight was being conducted without a flight plan under the provisions of 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed in the vicinity of the accident. The flight originated at the Great Bend Municipal Airport (GBD), Great Bend, Kansas about 0930. A line worker for the Fixed Base Operator (FBO) on the airport said she received a call from the pilot at 0846 requesting fuel for the airplane. She drove the fuel truck to the pilot's hangar and put in 4.7 gallons of fuel, which topped the tank. She said the pilot was in a "cheery, joking" mood. She didn't ask where the pilot was going as the ceiling was 800 feet and she didn't think he would be going very far. Later, at the FBO, the line worker received a radio call from the pilot asking to put him on the maintenance list to change his right tire, that as he was taxiing out he noticed he had a small area of chords showing. She told him they had the tire in stock and would put him on the list. He then made a departure call over the radio frequency that he was departing GBD. According to the pilot's family, the pilot sent a text message at 1004 stating that he and the passenger had arrived in Lucas, Kansas, about 46 nm north-northeast of GBD. The pilot's wife received another text message at 1013 stating the pilot wanted to meet for lunch after church. At 1223, she texted the pilot about their meeting for lunch and received no response. A witness reported about 1130 hearing an airplane north of him. He stepped out of the shed he was cleaning at the time and saw the airplane about a mile to his east flying at 200 to 300 ft above the ground. It had come out of a cloud bank and looked as if the airplane was trying to climb at a 45 degree angle. The witness said he thought nothing of it and went back to work. As he heard the airplane get closer to his house, he went out to see it fly over. As he looked for the airplane, he saw it in a 45-degree nose down pitch angle descending and impacting the ground. He immediately called 9-1-1. The witness said the engine sounded "weak as if it had no power" and that as the airplane was descending the pilot "was trying to pull up." PERSONNEL INFORMATIONThe pilot, age 49, held a private pilot certificate with an airplane single-engine land and instrument airplane ratings. According to the pilot's flight logs he had 1,528 total flying hours and 153 hours in the accident airplane. He had flown 30 hours in the 90 days preceding the accident; 22 of those hours being flown in the 30 days prior to the accident. The pilot held a valid second-class medical certificate dated October 11, 2012. The certificate showed the limitation, Must wear corrective lenses. The pilot successfully completed a flight review on February 4, 2013. AIRCRAFT INFORMATIONThe amateur-built, tandem two-place, high wing, single-engine airplane, serial number 045, was originally certificated in the experimental category by the original owner in 1997. It was registered to the owner on June 8, 2010. The airplane was powered by one Lycoming O-290-G carbureted; 4-cylinder horizontally opposed reciprocating engine, rated at 125 horsepower at 2,450 rpm. According to the manufacturer, the estimated fuel consumption of the engine at a normal cruise power setting was between 10.5 to 11 gallons per hour. A review of the available engine logbooks showed the airplane had completed an annual condition inspection on May 2, 2009. The tachometer time at the inspection was 392.8 hours. Other logbooks that might have contained the airplane's most recent condition inspection were not located. The tachometer time on the airplane at the accident site was 492.64 hours. METEOROLOGICAL INFORMATIONAt 1135, the automated weather observation facility at GBD, located 6 miles south from the accident location, reported wind from 120 degrees at 8 knots, overcast clouds at 1,200 ft, visibility 9 miles, temperature 64 degrees Fahrenheit (F), dew point 57 degrees F, and altimeter 30.06 inches of mercury. AIRPORT INFORMATIONThe amateur-built, tandem two-place, high wing, single-engine airplane, serial number 045, was originally certificated in the experimental category by the original owner in 1997. It was registered to the owner on June 8, 2010. The airplane was powered by one Lycoming O-290-G carbureted; 4-cylinder horizontally opposed reciprocating engine, rated at 125 horsepower at 2,450 rpm. According to the manufacturer, the estimated fuel consumption of the engine at a normal cruise power setting was between 10.5 to 11 gallons per hour. A review of the available engine logbooks showed the airplane had completed an annual condition inspection on May 2, 2009. The tachometer time at the inspection was 392.8 hours. Other logbooks that might have contained the airplane's most recent condition inspection were not located. The tachometer time on the airplane at the accident site was 492.64 hours. WRECKAGE AND IMPACT INFORMATIONThe airplane impacted in a windrowed corn stubble field about 6 miles north of the GBD. The accident site began with a 16-inch deep impact scar. Impressions in the ground that emanated out from the deepest part of the impact scar corresponded to impacts from the airplane's top wing and main landing gear. Pieces of the airplane's wing, cowling, and forward fuselage were located in the impact scar. Airplane pieces spanned outward from the impact scar about 122 feet to the airplane main wreckage. The airplane main wreckage consisted of the top wing, the tandem cockpit area, main landing gear, engine, propeller, aft fuselage, empennage, and tailwheel. The airplane rested upright and was oriented 160 degrees from the initial impact scar. The top wing was broken at the wing struts and crushed aft. The ailerons remained attached. The cowling and cockpit area were broken downward and aft. The main landing gear were bent and broken aft. The engine was broken downward and aft. A fuel tank behind the engine was crushed and broken. No physical signs or smell of fuel were present. Both blades of the two-bladed wood propeller were broken aft and showed no signs of rotational rubs or scratches. The front and rear seat windscreens were broken out and fragmented. The fuselage aft of the rear cockpit seat, empennage, and tailwheel were intact. Flight control continuity was confirmed. The engine and fuel tank were retained for further examination. MEDICAL AND PATHOLOGICAL INFORMATIONAn autopsy was performed on the pilot on June 8, 2014, by the Barton County, Kansas Coroner, at Hays, Kansas. The FAA's Civil Aerospace Medical Institute performed forensic toxicology on specimens from the pilot. The results were negative for all tests conducted. TESTS AND RESEARCHAn examination of the engine revealed no anomalies that would have prevented the engine from producing power. A reconstruction of the metal fuel tank confirmed airplane drawings that showed the fuel tank's volume as 4,172 cubic inches, therefore capable of holding 18.06 gallons of fuel. Based on the engine's fuel consumption rate of 10.5 gallons per hour, the airplane would have been able to fly for 1 hour and 42 minutes.

Probable Cause and Findings

The pilot's improper preflight planning, which led to a loss of engine power due to fuel exhaustion. Contributing to the accident was the pilot's loss of airplane control during the forced landing.
