A factor was the soft terrain. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Runway/land/takeoff/taxi surface: soft surface](https://openairdocs.org/ntsb-findings/03023020): Environmental issues › Physical environment · Not specified (probable cause); cases with it: [North American T-28D, 1 case](https://openairdocs.org/ntsb-findings/03023020/cases.md?model=6402508), [All aircraft, 264 cases](https://openairdocs.org/ntsb-findings/03023020/cases.md) - [Not determined](https://openairdocs.org/ntsb-findings/05000000): Not determined › Not determined · Unknown/Not determined (probable cause); cases with it: [North American T-28D, 1 case](https://openairdocs.org/ntsb-findings/05000000/cases.md?model=6402508), [All aircraft, 2,247 cases](https://openairdocs.org/ntsb-findings/05000000/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Enroute-cruise: Loss of engine power (total)](https://openairdocs.org/ntsb-events/341) (defining event); cases with it: [North American T-28D, 1 case](https://openairdocs.org/ntsb-events/341/sequence.md?model=6402508), [All aircraft, 3,820 cases](https://openairdocs.org/ntsb-events/341/sequence.md) - [Emergency descent: Collision with terr/obj (non-CFIT) ](https://openairdocs.org/ntsb-events/470); cases with it: [North American T-28D, 1 case](https://openairdocs.org/ntsb-events/470/sequence.md?model=6402508), [All aircraft, 10,189 cases](https://openairdocs.org/ntsb-events/470/sequence.md) ## Analysis In a written statement provided to the NTSB, the pilot reported that the airplane was in cruise flight at approximately 3,000 feet above ground level when the oil pressure gauge began to fluctuate. The pilot observed that the oil temperature and cylinder head temperature readings remained within the normal range. Additionally, the pilot stated that the engine "shuddered" several times before he experienced a total loss of engine power. Due to altitude and airspeed, the pilot reported that the only landing area available was a "soft, sandy, field." During the landing roll out the left main gear and nose gear dug into the soft terrain resulting in the collapse of the left main and nose landing gear. The airplane sustained substantial damage to the left wing. The pilot, sole occupant of the airplane, was able to egress without assistance. ## Factual narrative In a written statement provided to the NTSB, the pilot reported that the airplane was in cruise flight at approximately 3,000 feet above ground level when the oil pressure gauge began to fluctuate.
