NTSB Factual Report

On September 1, 2017, about 1710 eastern daylight time, a Cessna U206G, N4615X, operated by Waters Aero-Marine, doing business as Penobscot Island Air, was substantially damaged during a forced landing near Harpswell, Maine. The commercial pilot sustained minor injuries. Visual meteorological conditions prevailed, and a company visual flight rules flight plan was filed for the flight operated under the provisions of 14 Code of Federal Regulations Part 91, which departed Knox County Regional Airport (RKD), Rockland, Maine, about 1645, destined for Portland International Jetport (PWM), Portland, Maine.

According to the pilot, while in cruise flight at 2,500 ft en route to PWM, about 6 nautical miles from Brunswick Executive Airport (BXM), Brunswick, Maine, he heard a "loud bang," followed by a total loss of engine power. He immediately transmitted a distress call to Portland Approach Control, and advised that he was going to attempt to land at BXM. The pilot then advised on the Penobscot Island Air company frequency of his situation and his intentions. He then performed the emergency procedures for securing the engine and continued with the emergency landing.

At 600 ft the pilot realized that the airplane was not going to reach BXM and transmitted his intentions to make an off-airport landing. Upon landing the airplane bounced, traveled about 150 ft, and touched down again. The nose landing gear entered a small drainage ditch; the airplane nosed over, and came to rest inverted. The pilot then verified that all the engine controls and electronics were shut off, and egressed through the pilot's door, which he had opened on touchdown.

According to Federal Aviation Administration (FAA) airman records and pilot records, the pilot held a commercial pilot certificate with ratings for airplane single-engine land, airplane single-engine sea, airplane multi-engine land, and instrument airplane. He also held a flight instructor certificate with a rating for airplane single engine. His most recent FAA second-class medical certificate was issued on May 18, 2017. He reported that he had accrued 2,400 total hours of flight experience, 800 of which was in the accident airplane, make and model.

According to FAA airworthiness and maintenance records, the airplane was manufactured in 1979. Its most recent 100-hour inspection was completed on August 28, 2017. At the time of the inspection, the airplane had accrued 7,359.1 total hours of operation, and the engine had accrued 1,694 total hours of operation since major overhaul.

The airplane was retained for further examination.
