Aviation Accident Preliminary Report - National Transportation Safety Board:


Location: Houston, TX
Accident Number: CEN18LA086
Date & Time: 01/19/2018, 1600 CST
Registration: N6UP
Injuries: 4 None
Flight Conducted Under: Part 91: General Aviation - Business 

On January 19, 2018, about 1600 central standard time, a Swearingen SA227-TT airplane, N6UP, experienced an electrical malfunction during cruise flight and executed a forced landing to Ellington Airport (EFD), Houston, Texas. The two pilots and two passengers were not injured, and the airplane sustained substantial damage to both engines during landing. The airplane was registered to and operated by AIRCO JN LLC, Freedom, Oklahoma, as a 14 Code of Federal Regulations Part 91 business flight. Instrument meteorological conditions prevailed at the time of the accident, and an instrument flight rules flight plan had been filed. The flight departed Beaumont, Texas, and was destined for Uvalde, Texas.

According to one of the pilots, while in cruise flight maneuvering around thunderstorm activity, the airplane lost electrical power. The pilots attempted to troubleshoot the problem and could not regain electrical power. The pilots declared an emergency and diverted to EFD. Due to the loss of electrical power, the pilots manually extended the landing gear and could not verify if all the landing gear were down and locked. During the forced landing, the nose landing gear was retracted, and the airplane skidded on the forward fuselage after touchdown. Due to the nose gear being retracted during landing, both propeller assemblies and engines sustained substantial damage.

The airplane was recovered from the runway for further examination.
