Pagosa Springs, CO, US

On September 6, 2004, a Mooney M20D (registration N1907Y) was involved in an aviation accident near Pagosa Springs, CO. Investigators recorded the probable cause as: the pilot's inadequate preflight planning and his failure to maintain directional control. Contributing factors were the pilot's failure to abort the takeoff, and the rough and uneven runway surface. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

During takeoff roll, the airplane departed the left side of a runway under reconstruction, skipped across the ground, struck a 600-pound concrete block, and came to rest inverted. A post-impact fire ensued. The aircraft had unresolved discrepancies and the usable runway was rough and uneven.

Background

The pilot and his wife made several attempts to take off but aborted each one. Airport personnel reported that when the pilot came into the office, he appeared thoroughly shaken by the experience. He told employees he would not take off from the airport until runway construction had been completed and the entire length of the runway was made available. He also told a mechanic that there was a shimmy in the nose wheel steering.

Maintenance and Delivery Attempts

The pilot contracted with a local flight instructor to deliver the airplane after repairs had been made. Delivery was postponed on three different occasions over a period of two months when discrepancies were discovered: the right fuel tank leaked and the VOR receivers did not work; instead of being mounted on the windshield center post, the magnetic compass dangled by a few wires underneath the instrument panel; the airspeed indicator was twisted about 60 degrees in the instrument panel; the fuel cap O-rings were "severely cracked and worn"; the communication radios stopped working; the battery required charging; and the airplane required a jump-start. There were numerous 9-volt and AA batteries on the rear floor and in the door pockets.

Decision to Ferry

The flight instructor elected not to deliver the airplane. The pilot elected to ferry the airplane home.

Accident Sequence

During the takeoff roll, the airplane departed the left side of the runway and skipped across the ground before striking a 600-pound concrete block and coming to rest inverted. A post-impact fire ensued.

Runway Conditions

The 9,000-foot runway was undergoing reconstruction and only 3,900 feet was available. An additional 600-foot displaced threshold was available for takeoffs. The usable portion of runway was rough and uneven.
