On August 11, 2021 about 0900 mountain daylight time, a Cessna 425 Conquest 1, N723MB, sustained substantial damage when it was involved in an accident near Helena, Montana. The pilot and two passengers sustained serious injuries. The airplane was operated as a Title 14 Code of Federal Regulations (CFR) Part 91 business flight. The pilot stated that on the morning of the accident, he physically refueled the airplane to full wing tanks by adding an additional 207 gallons of Jet A. Shortly thereafter, he departed from his home airport in Faribault, Minnesota and continued to his destination at a cruise altitude of 24,000 feet mean sea level. Investigators reviewed Air Traffic Control transmissions and flight track data covering the area of the accident using Federal Aviation Administration (FAA) provided Automatic Dependent SurveillanceBroadcast (ADS-B) data. While en route, at 0847:35, the pilot reported to an air traffic controller that the airplane had an engine flame out and requested a descent. The pilot opted to divert from the originally planned destination and contacted Helena approach control. He stated that the airplane was 16 miles from Helena and descending through 19,000 feet advising the controller that he may need to lose altitude to land on runway 27. The controller responded that the pilot could maneuver north of the airport to then align with the right base leg of the traffic pattern to the runway. At 0852:59 the pilot reported to the air traffic controller that he had an hour and a half of fuel on board and about 3 minutes later the airplane made a right turn to the north. At 0857:15, with the airplane about 7,900 feet msl, the pilot reported that the right engine experienced a loss of power (see Figure 1 below). At 0859:02, the pilot reported the airplane was going to collided with trees. The airplane came to rest with the right wing and empennage severed from the fuselage. The pilot noted that the airplane had undergone an annual inspection in March 2021, equating to about 10 flight hours prior to the accident.

Circumstances:
On April 20, 2020 about 0950 mountain daylight time, a Piper PA-31T1 airplane, N926K, was destroyed when it was involved in an accident about 1-1/2 miles west of Billings Logan International Airport (BIL), Billings, Montana. The airline transport pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 local flight. According to ATC information, the pilot requested to taxi to runway 28L for takeoff, and then perform pattern work, and land on runway 28R at BIL. After the pilot held short of runway 28L, the controller cleared the pilot for takeoff with instructions to extend the upwind leg. Shortly after takeoff, the pilot was instructed to enter the left traffic pattern for runway 28R twice, with no response. A subsequent attempt was made to establish communication, with no response. About a minute and a half after the airplane departed, a column of smoke was observed west of the airport. Radar data showed the airplane departing runway 28L and remaining on runway centerline heading for the length of the flight. The airplane's altitude climbed to about 100 ft above ground level and the airplane's groundspeed increased to 81 knots soon after departure, and then decreased to 70 knots before dropping off radar. Witnesses located near the departure end of runway 28L watched the airplane through a window, depart the runway with its gear not retracted. The airplane was lower than normal as it neared the end of the runway. All the witnesses moved outside to watch as the airplane flew away from their location. One of the witnesses stated that the airplane had a "slow descent trajectory and a slight-nose up attitude." The airplane passed over a hill and out of view. None of the witness reportedly saw the accident sequence but saw the column of smoke rising from the accident site. Another witness who was sitting in his vehicle near the accident site saw the airplane pass about 250 ft in front of his position. The airplane's wings were level and the landing gear was up when it struck the ground. He lost sight of the airplane as it flew into a nearby coulee. Ground scars found near the top of a coulee consisted of the airplane's fuselage impact mark and symmetrical propeller strikes consistent with the airplane impacting the ground in a shallow, nose-up, wings-level attitude. The airplane then continued over the coulee about 410 ft, and about 75 ft down before impacting the side of the coulee where a postimpact fire ensued. All major structural components of the airplane were located within the debris field.
