Probable cause

The total loss of engine power during climb after takeoff for reasons that could not be determined because postaccident examination did not reveal any anomalies that would have precluded normal operation.

Findings · 1

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot stated that the airplane experienced a total loss of engine power while climbing through about 300 feet above ground level after takeoff. The pilot performed a forced landing to an area off the departure end of the runway where the airplane impacted the ground and struck several objects. During postaccident interviews, the pilot said that he shut off the fuel selector valves before exiting the airplane. The engine operated during a postaccident test run when the emergency fuel shutoff valve was in the on position and the fuel selector valve was set to the right fuel tank.

Factual narrative

On July 23, 2011, about 1617 central daylight time, a Cessna 172B, N7624X, experienced a total loss of engine power after takeoff from Middleton Municipal - Morey Field Airport (C29), Middleton, Wisconsin. The pilot subsequently made a forced landing off the departure end of the runway and impacted terrain, a tree, and a fence. The certificated private pilot and a passenger sustained no injuries. The airplane sustained substantial damage to both wings. The airplane was registered to and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight destined for the Wittman Regional Airport, Oshkosh, Wisconsin. The flight was originating at the time of the accident. The pilot stated that the airplane was fueled with 20 gallons of 100 low lead fuel at C29 prior to departing on runway 10 (4,000 feet by 100 feet, asphalt). He taxied to runway 10 and a before takeoff checklist. After waiting for a departing airplane to clear the area, he began the takeoff. The takeoff roll was about 1,200 feet. A "few seconds" after rotation and about 300 feet above ground level, the engine lost power. The pilot "immediately" reduced pitch attitude in order to avoid a stall. He performed a "very slight" turn to the left to avoid a light structure, and the airplane then contacted the ground similar to a hard landing. The airplane struck a berm, became airborne and struck a street curb, tree, and a fence. The airplane was registered as an experimental research and development exhibition aircraft since January 31, 2011. The airplane was equipped with a Teledyne Continental Motors IO-360D engine and a McCauley two-bladed D2A34C67/76C propeller, both of which were installed under supplemental type certificate SA01626WI. The airplane was equipped with a fuel selector between the forward seats and a guarded emergency fuel shutoff valve located under the cockpit mixture control. There was a three position (low, high, and off) auxiliary fuel pump control switch below the cockpit throttle control. The fuel selector provided fuel to a reservoir tank from the selected wing fuel tank. The guarded emergency fuel shutoff valve is installed between the fuel reservoir tank, estimated to be one gallon in capacity, and the auxiliary fuel pump, which is mounted on the engine firewall. On July 27, 2011, an airworthiness safety inspector from the Milwaukee Flight Standards District Office conducted an engine run without removing the engine from the airframe. An attempt was made to start the engine but was unsuccessful because the emergency fuel shutoff valve and fuel selector were in the off positions. The emergency fuel shutoff valve was opened and the fuel selector valve was positioned to the right fuel tank. The engine was then able to be started and ran briefly at a low engine speed with extreme vibration due to the propeller being damaged.
