Accident Details
On January 24, 2026, at approximately 0712 central daylight time, a Piper PA-46-350P airplane, registration N91MK, was substantially damaged during a forced landing near Sioux City, Iowa. The flight was conducted as a personal flight under Title 14 Code of Federal Regulations Part 91. The pilot and the sole passenger were uninjured.
Pilot Report
The pilot reported that after the initial climb and immediately after leveling off at 2,500 feet mean sea level, he felt the airplane make two "thugs" and observed a fluctuation in manifold pressure. Shortly thereafter, a drop in engine oil pressure was noted. The pilot informed the air traffic control tower controller of his intention to turn back toward the airport. As the airplane was established on a north heading, a loud "boom" was heard, followed by a complete loss of engine power.
Forced Landing and Damage
The pilot executed a forced landing to a field. During the landing, the airplane's engine and left wing impacted terrain and separated from the airframe. The forward fuselage and right wing sustained substantial damage. The wreckage was retained for further examination.
Prior Incident
The pilot stated that on a previous flight, four days before the accident flight, a similar "thug" was experienced. However, that event did not result in any other abnormal indications.
