2004-10-03: Piper PA-23-180 (N173DC) — Beatrice, NE

Beatrice, NE, US

On October 3, 2004, a Piper PA-23-180 (registration N173DC) was involved in an aviation accident near Beatrice, NE. Investigators recorded the probable cause as: The loss of right engine power undetermined reasons. Factors to the accident were the loss of engine power at a low altitude and below the single engine best rate of climb airspeed (Vyse), and the unsuitable terrain encountered during the subsequent forced… This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An airplane was destroyed by a post-impact fire following a forced landing shortly after takeoff; the pilot had reported a right engine exhaust gas temperature exceedance and a subsequent yaw.

Accident Sequence

The airplane was destroyed during a post-impact fire after a forced landing shortly after takeoff. The pilot had previously performed a precautionary landing after noticing the exhaust gas temperature indicator for the number one cylinder of the right engine showed elevated temperatures. After that landing, the pilot discussed the problem with his mechanic, and they decided it was likely an instrument or probe issue, as no corroborating systems indicated a problem.

Preflight and Takeoff

Before departing from BIE, the pilot fueled the main fuel tanks with 72 total gallons. The pilot reported that the winds favored runway 31. During the takeoff, he held the brakes while increasing power on both engines to 22 inches of manifold pressure. He then released the brakes, accelerated through redline, and rotated without anomalies.

Engine Indication and Loss of Control

During the initial climb, between 30 and 60 feet above ground level, the pilot observed the right engine exhaust gas temperature "going through the high limit." This was followed by a "whooshing air sound and violent yaw to the right." The pilot stated the airplane was "still low and slow" and "never got to blue line [Vyse] or enough altitude to nose down for airspeed." He reported he did not have "enough altitude or climb power" to clear the power lines off the north side of the airport. The pilot stated he did not have "enough airspeed for effective directional control" and he "continued shallow right turn with continued buffeting."

Forced Landing and Impact

The pilot decided to land diagonally across highway 77. The aircraft impacted a highway embankment, and a post-impact fire ensued.

Investigation Findings

No discrepancies were found with either engine that would have prevented normal operation. A fuel sample was taken from the source that fueled the accident airplane prior to the accident; the sample was examined and found void of visible contamination and/or water. Both propellers were found in the feathered position.
