Location: Yuma, AZ
Accident Number: WPR18LA250
Date & Time: 08/27/2018, 1036 MST
Registration: N8162H
Aircraft: Stoddard Hamilton GLASAIR SUPER II
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal 

On August 27, 2018, at 1036 mountain standard time, an experimental amateur-built Glasair Super 2SRG (builder Michael Hyneman), N8162H, lost engine power and landed in a parking lot just short of Yuma Marine Corps Air Station/Yuma International Airport (NYL), Yuma, Arizona. The private pilot was not injured, and the airplane sustained substantial damage to the aft fuselage during the forced landing. The airplane was registered to Rich Airplanes LLC., and operated by the pilot under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. The cross-country flight departed Montgomery-Gibbs Executive Airport, San Diego, California, at 0942 Pacific daylight time with a planned destination of Marana Regional Airport, Marana, Arizona. Visual meteorological conditions prevailed, and no flight plan had been filed.

The pilot stated that he completed a preflight inspection prior to departure, and the airplane performed appropriately during the runup. The departure and climb were uneventful, and after reaching 9,500 ft mean sea level, he configured the airplane for cruise. About 35 minutes later the airplane's multifunction display indicated an "electrical problem, check voltage" alert. He noticed that the airplanes main battery was not charging, and that the alternator field toggle switch/circuit breaker had tripped off, but the alternator circuit breaker was still in. He reset the toggle switch, and the battery began to charge again, and all systems appeared normal. About 5 minutes later, the display indicated the same warning, and the toggle switch again tripped. He cycled the switch and the battery started to charge again.

About 2 minutes later he noticed that the engine manifold pressure was beginning to drop along with the airplane's airspeed. He stated that the fuel flow, fuel pressure, and oil pressure appeared normal, and he could not discern an appreciable reduction in cylinder head or exhaust gas temperatures. He selected an alternate fuel tank, turned on the auxiliary electrical fuel pump, and adjusted the throttle, with no change, and by now the multifunction displayed indicated the engine was producing 30% of its rated power.

He declared an emergency with Yuma Radar Approach Control and was provided a local control frequency for NYL. The pilot stated that the engine was still producing partial power when the local tower controller cleared him for an emergency landing on runway 17, and then changed the clearance to runway 21L, which was longer. The pilot stated that he was too high to land, so performed a 360° turn at the north end of the runway, but during the turn the engine lost all power, and the airplane landed short.
