Colorado Aviation Accidents & Incidents

On May 17, 1998, approximately 2130 mountain daylight time, a Mooney M20E, N1306W, operated by Flight Training, Inc., was substantially damaged when collided with terrain while taxiing from landing at Watkins, Colorado. The private pilot and one passenger were not injured, but another passenger sustained a minor injury. Visual meteorological conditions prevailed, and a VFR flight plan had been filed. The flight was conducted under Title 14 CFR Part 91, and had originated at Akron, Colorado, approximately 2030.

According to the pilot's accident report, while en route to the Front Range Airport, the cockpit "lights dimmed [electrical charging system failure]." He shut down all electrical devices with the exception of the navigation lights and rotating beacon. He said that as he got closer to his destination, he "did not have enough [electrical] power to communicate or turn on the runway lighting system." Front Range Airport's approach lights came on and he flew towards the airport. He then noticed two airplanes in the traffic pattern. He landed on runway 17.

Although runway 17 is equipped with pilot-controlled high intensity runway lights, the parallel taxiway is not illuminated0. The pilot said that after he turned off the runway, he tracked the taxiway centerline. He said he "was blind. . .The battery was exhausted. . .The visibility was near zero. I was fixated on the center line of the taxiway and negotiated some turns. I lost the center line and went off the taxi way, where I pulled back on the elevator control for soft field procedure. There was a sensation of falling. The aircraft had gone off a sharp embankment."

According to the airport's night manager, he was driving to the fuel farm when he encountered the pilot walking along the taxiway. The pilot told him what had happened, then expressed concern that the airplane might be a hazard to other traffic and offered to "turn on the navigation lights, if necessary." The night manager said he thought the remark was odd if the airplane had had a total electrical failure.

An FAA inspector later examined the airplane. When the master switch was closed, all electrical components functioned normally. Additionally, the inspector said that, based on the point where the aircraft departed the taxiway and its point of impact, taxi speed was excessive.

The airplane operator asked a mechanic to examine the airplane. In his written statement, the mechanic said he "checked all lights [internal and external] and found them operational except for the landing light, which had been broken during the off-pavement excursion. Closer inspection of the landing light showed that when it was broken, it was not illuminated. A specific gravity check. . .found the battery to be fully charged. Inspection of the battery relays and primary power bus also showed no defects."

The airplane owner contacted this investigator and said that according to the operator's records, the Hobbs meter and tachom
