## Analysis

THE PLT HAD BEEN HAVING NUMEROUS PROBLEMS WITH HIS HOMEBUILT ACFT'S ENG RUNNING ROUGH BEFORE THIS FLT. SHORTLY AFTER TAKEOFF A LOSS OF PWR OCCURRED. IT WAS A HOT DAY WITH THE TEMP BEING 90 DEGS F OR BETTER. FAA INSPECTORS FOUND THE TOURQUE VALUE TO BE QUESTIONABLE ON ALL SPARK PLUGS. THE CARBURETOR AND MIXTURE CABLES SHOWED A SMALL AMOUNT OF SLIPPAGEWITHIN THE HOUSING. THE MAIN PWR WIRE PROVIDING THE NECESSARY 12 VOLTS PWR FOR THE OPERATION OF THIS SYSTEM WAS FOUND LOOSE ON THE TERMINAL OF THE ACFT'S MASTER SWITCH. TWO TOTALLY DIFFERENT IGNITION SYSTEMS HAD BEEN INSTALLED. FAA INSPECTORS STATED THAT THERE WAS NO ACCURATE MEANS OF DETERMINING THE TIMING.

- [Accident 19850708064279A](https://openairdocs.org/incident/19850708064279A), Jul 8, 1985: Amtr KR2, Pullman, WA, Destroyed. Engine lost power after takeoff. Wings wavered, nose dropped and aircraft struck ground. Master switch wire loose.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
