NTSB Factual Report

On August 27, 2018, about 1250 eastern daylight time, a Cessna 182L, N3115R, nosed over following a landing overrun at Cranland Airport (28M), Hanson, Massachusetts. The commercial pilot was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the local skydiving flight, which originated at 28M and was operated under the provisions of Title 14 Code of Federal Regulations Part 91.

The pilot reported completing a thorough preflight inspection and runup prior to the accident flight, noting that there were no mechanical malfunctions or failures with the airplane prior to the flight that would have precluded normal operation, and no abnormal indications or battery discharge indications during the runup preceding takeoff. A witness stated that the airplane was jump-started by a vehicle just prior to the accident flight.

About 2,000 ft during the initial climb, the airplane experienced a radio failure and the pilot noted a slight change in engine sound. He consulted with the jumpmaster and continued to climb to 7,500 ft to allow the two pairs of skydivers to jump. He reported engine roughness after the jumpers departed the airplane. He considered going to a nearby airport about 8 miles southeast that offered longer runways but did not want to go to an airport that was unfamiliar to him. Instead, he circled down over the airport, keeping his approach "a little faster and higher than normal" so that if the engine lost total power he could still reach the runway. After extending full flaps, he tried to "bleed off speed" and lose altitude as quickly as possible. He landed longer than usual but preferred to not execute a go-around due to the rough-running engine. Despite maximum braking, the airplane overran the departure end of runway 18, encountered a ditch, nosed over, and came to rest inverted.

According to the jumpmaster, he noted no engine problems or other anomalies besides the radio failure prior to jumping. Once on the ground, he observed the landing and left main tire smoking from the pilot "locking up the brakes." According to the second jumpmaster, once back on the ground he saw the airplane "arriving fast" and heard the airplane braking before it overran the runway.

A review of the airport video revealed that the airplane touched down near the midpoint of the 1,760-ft-long runway. Additionally, a Federal Aviation Administration who responded to 28M shortly after the accident noted a quartering tailwind for the airplane's direction of landing. The recorded wind at an airport located 8 miles southeast of the accident site, about the time of the accident, was variable at 5 knots.

The airplane came to rest inverted 183 ft beyond the departure end of runway 18. Examination of the wreckage revealed that the airframe sustained substantial damage to the fuselage, both wings, rudder, and vertical stabilizer. The flaps were in the extended position. The main landing gear tires both displayed significant tread wear on one side with visible holes in the tread area. The runway displayed tire skid marks with geometry consistent to the accident airplane for537 ft. Additionally, rim marks were evident 158 ft after the first contiguous skid marks.

Examination of the airplane revealed that the alternator belt was located off the pulleys and on the lower right side of the engine firewall. It was examined, and no anomalies were noted. The battery was disconnected during the accident sequence, with the left post separated at impact. For examination, a replacement battery was wired to the airplane and the flaps operated normally. A multimeter was applied to the accident battery and it indicated 12.3 volts. Except for the alternator belt located off the pully, the engine was examined and no evidence of preimpact mechanical malfunctions were observed. Testing of the brakes showed that they were operational and did not reveal evidence any preimpact mechanical anomalies.
