On August 27, 2018, N3115R departed the end of runway 18 at the Cranland Airport in Hanson, MA (28M) during landing at approximately 12:50 eastern daylight time. After landing the pilot was unable to stop the aircraft prior to the end of the runway. The aircraft departed the runway slightly right of the runway centerline. The aircraft continued through the grass for approximately 150? Where the aircraft impacted a slightly elevated dirt road causing the nose gear to shear off. The aircraft continued approximately 40? Across the road and, upon exiting the opposite side of the road, the propeller and spinner dug into the ground causing the aircraft to rotate around the spinner and flipped over onto its roof. The pilot self-extricated from the accident aircraft and suffered only minor, superficial injuries.

The touchdown spot on the runway cannot be determined as airport surveillance video is partially blocked by an open hangar door. However, skid marks from the main wheels locking during landing first appear approximately 875? From the runway 18 threshold. Approximately 450? From the end of runway 18 there is evidence of the right main wheel deflating and approximately 250? From the end of runway 18 there is further evidence of the left main wheel deflating. An examination of the accident aircraft showed the flaps were indicating in the full extended position, 30 degrees. However, the flap selector was found in the 0 degree position.

Weather information:

At the estimated time of the accident, the plymouth, MA (pym) weather observation (the nearest airport with weather reporting) reported the weather as wind variable at 5 knots, 10 statute miles visibility, few clouds at 4,400?, temperature of 31 degrees celsius, dew point of 19 degrees celsius, and an altimeter of 30.04 inches of mercury. At approximately 13:15 eastern daylight time, the wind sock at 28M was depicting the wind out of the northwest, resulting in a quartering tailwind for a landing on runway 18.

Pilot information:

The pilot holds a commercial pilot certificate with airplane multi engine land, airplane single engine land, and instrument airplane ratings. His first class medical certificate is dated 04/07/2018 with a limitation of ?must wear corrective lenses.?

Aircraft information:

The aircraft is a 1967 Cessna 182L, serial number 18258515. The aircraft is equipped with a Continental O-470-U-50 engine, which produces 235 horsepower. Additional aircraft information will be updated once the aircraft maintenance records are obtained from the operator.

Wreckage information:

Both blades of the propeller indicate damage consistent with the engine producing power at the time of impact with the ground. There was also significant damage noted on the empennage and vertical stabilizer caused when the vertical stabilizer impacted the ground. The negative battery terminal was ripped from the battery during the accident sequence. There was enough of the negative lead in the battery to test voltage. The accident battery tested at 12.3 volts with a multi-meter. A spare battery, measuring 12.3 volts using the same multi-meter, was connected to the aircraft power to check flap operation. The flaps retracted to the full up position and again to the full down position. There were no issues noted with the flap movement. When the engine cowling was removed, the alternator belt was discovered disconnected from the alternator pullies in the void between the heat shield and the firewall. There was no damage found on the belt or on the alternator and mounting brackets. All spark plugs appeared functional and produced a spark when the engine was hand cranked. Additionally, there was compression from all 6 cylinders. The right brake operated normally when tested but the left brake could not be moved or tested. There was brake fluid on the left brake reservoir.
