Aviation Accident Preliminary Report - National Transportation Safety Board:

Location: Wrightsville, GA
Accident Number: ERA20LA045
Date & Time: 11/30/2019, 1000 EST
Registration: N52CY
Aircraft: Yakovlev YAK 52
Injuries: 2 Minor
Flight Conducted Under: Part 91: General Aviation - Instructional

On November 30, 2019, about 1000 eastern standard time, a Yakovlev Yak 52, N52CY, was substantially damaged during an off-airport landing after experiencing a loss of engine power enroute near Wrightsville, Georgia. The flight instructor and private pilot sustained minor injuries. The airplane was registered to the flight instructor and operated by the private pilot as a Title 14 Code of Federal Regulations Part 91 personal flight. Day visual meteorological conditions prevailed, and no flight plan was filed. The flight originated from Waycross-Ware County Airport (AYS), Waycross, Georgia about 0915 and was destined for Kaolin Field Airport (OKZ), Sandersville, Georgia.

The private pilot reported this was the second day of a cross-country trip to move the airplane to Tennessee, from Florida, as the flight instructor had recently purchased the airplane. He reported that the flights the day prior were normal, and the accident flight takeoff and cruise progressed normally, until about 10 minutes from OKZ. While cruising at 3,500 ft mean sea level, there was a sudden heavy vibration from the engine that lasted about 5 seconds and resulted in a complete loss of engine power. He added that there was no indication that something was wrong with the engine, prior to the heavy vibration.

The flight instructor reported the same heavy vibration and loss of engine power, and added that the vibration was so heavy, that an engine gauge fell out of its position into the back of the instrument panel during the event. He immediately took the flight controls and adjusted the throttle but received no response from the engine. He then attempted an engine restart, but when he engaged the starter, he saw one propeller blade remained fixed in the airstream. The flight instructor reported he then turned the airplane left to align with a long farm field, and while on final approach about 500 ft above ground, he extended the landing gear, which resulted in the airspeed decaying rapidly and a further increase in the descent rate. Subsequently, he reported that as the airplane entered the landing flare, it was "out of airspeed," and shortly after the nose wheel touched down the airplane nosed over and skidded to a stop.

According to a Federal Aviation Administration (FAA) inspector who examined the airplane at the accident site, the airplane came to rest upside down. All flight control surfaces remained attached, the nose wheel was located forward of the main wreckage, and no odor of fuel was present at the accident site; however, no breach of the fuel tanks was observed. One blade of the two bladed wooden propeller was cracked, but remained in one piece and attached to the propeller hub. The other propeller blade was fractured and only about 1/3 of its length remained attached to the hub; the remainder of this propeller blade was not located in the debris path or surrounding farm fields.

When the propeller was moved by hand, it was revealed that the engine had seized and would not rotate. A portion of the engine cylinders were submerged into the field and were not visible, but among the cylinders that were visible, all appeared to be intact and displayed no obvious damage. Some oil spraying was observed on the belly of the airplane, contained to where the exhaust pipe was located.

According to FAA airman records, the private pilot had ratings for airplane single and multi-engine land, and instrument airplane. He completed the FAA basic medical certificate course October 21, 2019. His most recent flight review was completed on November 19, 2019. He reported a total flight time of 1,920 hours, of which 4 hours were in the accident airplane make and model. In the past 90 days, he reported a total flight time of 4 hours.

According to FAA airman records, the flight instructor held an airline transport pilot certificate with a rating for airplane multi-engine land and a commercial pilot certificate with ratings for airplane single-engine land and sea, and glider. He held a private pilot certificate for rotorcraft-helicopter. He also held a flight instructor certificate for airplane single and multi-engine, instrument airplane, and glider. He did not hold a medical certificate. He reported a total flight time of 3,805 hours, of which 4 hours were in the accident airplane make and model. In the past 90 and 30 days, he reported a total flight time of 20 hours and 7 hours respectively.

According to FAA airworthiness and aircraft maintenance records, the 2-tandem seat former Union of Soviet Socialist Republics (USSR) aerobatic trainer was manufactured in 1988 and was powered by a Vedeneyev M14P nine-cylinder radial engine. The propeller was a wooden Vperod V530TA-D35. The most recent annual inspection was completed on November 1, 2019. According to the flight instructor, the airplane had not flown for a "couple of years" prior to the annual inspection and cross-country flight.

At 0955, the OKZ hourly weather observation, about 12 nautical miles north of the accident site, included wind from a heading of 210° at 4 knots, visibility 10 statute miles, overcast ceilings at 3,100 ft above ground, temperature 16°C, and dew point 10°C.

The airplane was retained for further examination.
