2004-04-16: Piper PA-12 (N3029M) — Copper Center, AK

Copper Center, AK, US

On April 16, 2004, a Piper PA-12 (registration N3029M) was involved in an aviation accident near Copper Center, AK. Investigators recorded the probable cause as: The pilot's selection of unsuitable terrain for takeoff, and his failure to utilize carburetor heat, which resulted in a loss of engine power during takeoff initial climb, and a subsequent encounter with snow-covered terrain. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A private pilot experienced a gradual engine power loss after takeoff from a muddy airstrip, leading to an emergency landing in a snow-covered field. The aircraft sustained damage to the right landing gear, wing, and fuselage. No mechanical malfunction was found.

Event Summary

After completing an annual inspection, a private pilot departed from a private airstrip adjacent to the maintenance facility. The airstrip surface was muddy and wet, with puddles of standing water. According to the pilot, the sky was overcast at about 5,500 feet, visibility was approximately 50 miles, and the temperature was around 45°F.

Takeoff and Engine Power Loss

During the takeoff roll, the pilot reported that the aircraft encountered a puddle, causing water to splash over the windshield. After becoming airborne and reaching about 50 feet above ground level, the engine power began to decrease slowly. The pilot noted no engine roughness or sputtering. As the engine rpm decreased, the airplane lost altitude.

Emergency Landing

The pilot selected an emergency landing area in a snow-covered field. During the landing, the airplane spun to the left, the right main landing gear collapsed, and the right wing struck the ground. The pilot reported that the aircraft sustained damage to the right landing gear, right wing, and fuselage.

Post-Accident Examination

The airplane was retrieved and examined by the maintenance facility mechanic and the pilot. No mechanical malfunction was found. The mechanic later reported to an FAA inspector that during the takeoff roll the airplane encountered several puddles of water. The mechanic also stated that "the temperature and environmental conditions were ideal for carburetor icing, and poor runway conditions were a contributing factor in the accident."
