Factual Information

On June 7, 2020, about 1513 eastern daylight time, a Team Mini-Max 1600R airplane, N827WS, was substantially damaged when it was involved in an accident near Marshall, Michigan. The pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight.

According to the pilot, the engine lost total power during initial climb after departing from a campground area. The pilot made a forced landing into a cornfield, which damaged both wing struts.

During the flight prior to the accident, the pilot noticed engine roughness that discontinued after he turned the fuel pump on. The pilot inspected the airplane after landing but was not able to find a rationale for the engine roughness.

Following the accident, examination of the engine revealed that the fuel supply line to the inlet fitting of the vacuum driven fuel pump was loose on the fitting. Although the clamp on the inlet fitting had been tightened to its maximum clamping position, the fuel supply line was still loose on the fitting and without a proper seal it was possible for air to enter the fuel system.

  1. a vacuum operated fuel pump is connected with a vacuum hose to the engine intake manifold where it gets its suction. It works due to the unevenness of the vacuum found with the fluttering or pulsation in the intake drawing fuel thru seperate fuel hoses from the tank(s) thru the fuel filter and to the engine.

  2. Two stroke engine. Not sure if above explanation is accurate.
