Aviation Accident Summary ANC96LA147

ANCHORAGE, AK, USA

Aircraft #1

N4012H

Rans 7

Analysis

The purpose of the flight was for the flight instructor (CFI) to become familiar with the homebuilt experimental airplane and to then teach the student pilot/owner, who was also aboard the airplane. According to the CFI, he was having continuing difficulty landing the airplane at the practice, gravel airstrip, and thought about leaving the airplane there and retrieving it later. He elected to fly the airplane to Merrill Field, in Anchorage, because it was getting dark and he wanted to get the airplane to its home base. He also noted that he assumed the paved runway at Merrill would be more difficult to land on. While landing at Merrill Field, the airplane bounced two or three times, and went off the right side of runway 24. The CFI attempted to abort the landing, but was unable to keep the airplane from striking airplanes parked on the ramp. The CFI said there was no preimpact mechanical difficulties with airplane.

Factual Information

On September 8, 1996, about 2104 Alaska daylight time, a wheel equipped, home built experimental airplane, N4012H, sustained substantial damage while landing at Merrill Field, Anchorage, Alaska. The commercial certificated pilot/flight instructor and the owner/pilot-rated passenger aboard were not injured. The local, 14 CFR Part 91 flight operated in visual meteorological conditions without a flight plan. During a telephone interview with the NTSB investigator-in-charge on September 10, the pilot-in-command (PIC) stated that the purpose of the flight was for him to become familiar with the accident airplane's flight characteristics. Once he became familiar with the airplane, he intended to instruct the owner, a student pilot, and help him to become familiar with the airplane. The PIC said they departed Merrill Field about 1800, and flew across Cook Inlet to a gravel airstrip at Goose Bay to practice landings and high speed taxi tests. This was the pilot's first flight in the airplane. The PIC indicated that the airplane was difficult for him to control at low speeds, and touchy on the controls. He said he had difficulty landing the airplane at Goose Bay, and debated leaving the airplane there instead of flying it back to Anchorage, where he would have to land on a paved, less forgiving, runway. He said he elected to fly to Merrill Field, as Goose Bay is a remote location, and getting a ride to Anchorage would have been difficult. The PIC said the airplane bounced two or three times after touchdown on runway 24. On the last bounce, the airplane went to the right, towards the ramp area. He said he initially added power, with the intent of aborting the landing, but experienced difficulty in controlling the airplane. The airplane continued to go to the right, towards parked aircraft, and he decided to reduce the power and land. The airplane landed off the paved surface, and collided with parked airplanes in the ramp area. The airplane owner and the PIC said there was no known preaccident mechanical anomaly with the airplane, only that it was difficult to control at slow airspeeds.

Probable Cause and Findings

the pilot's improper recovery from a bounced landing and failure to maintain control of the aircraft. A factor relatated to the accident was: the pilot's improper decision to continue the flight after he identified he was having difficulty landing the airplane.
