| NTSB Identification: IAD96LA065. The docket is stored in the (offline) NTSB Imaging System. |
| Accident occurred Friday, April 19, 1996 at CLINTON, MD |
| Aircraft: Cessna 150H, registration: N6508S |
| Injuries: 1 Uninjured |
| Event: 20001208X05590 Status: Final Report Approved On Tuesday, October 22, 1996 |
| NTSB Preliminary Narrative (6120.19A) |
| On April 19, 1996, at about 1130 eastern daylight time, a Cessna 150H, N6508S, experienced a loss of engine power shortly after takeoff at the |
| Hyde Field Airport, near Clinton, Maryland. The airplane sustained substantial damage when the left wing impacted a tree during the ensuing |
| forced landing. The student pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed for the flight, no flight plan was |
| filed. The local flight was conducted under 14 CFR Part 91. |
| The student pilot stated that he was practicing full stop takeoffs and landings at Hyde Field when the accident occurred. He reported that he |
| had completed 6 takeoffs and landings without incident. He stated that during the 7th takeoff, as the airplane climbed through about 300 to 400 |
| feet above ground level (AGL), he noticed a partial loss of engine power. He stated that the tachometer was reading about 2000 revolutions per |
| minute (RPM), and he checked the throttle to insure that it was full forward. He stated that he thought he might be experiencing carburetor icing, |
| so he turned the carburetor heat on. The student pilot reported that when the engine continued to lose power, he turned the carburetor heat |
| off, and began to prepare for an off airport landing. |
| The student pilot stated that as he maneuvered for the forced landing, the engine began to "sputter" and then lost power completely. He stated |
| that he saw a field to his left about 1/2 mile southwest of the airport. He said he picked a spot, but he flared too high, about 15 to 20 feet AGL. |
| He reported that he saw trees coming at him, and tried to turn to the right to avoid them. The student pilot stated that the "...left wing struck a |
| tree and swung the aircraft around into some other trees, before it came to an abrupt stop." |
| The student pilot stated that the temperature at the time of the accident was about 70 degrees, and he believed that the loss of engine power |
| was due to carburetor ice. Postaccident examination of the aircraft, engine, and systems, revealed no evidence of preimpact mechanical |
| malfunction. On April 20, 1996, a test run of the engine was conducted. According to the Federal Aviation Administration (FAA) Inspector, the |
| airplane engine started on the first attempt, and the engine and systems appeared to be capable of normal operation. |
| NTSB Final Narrative (6120.4) |
| The student pilot stated that he was practicing full stop takeoffs and landings. As the airplane climbed through about 300 to 400 feet AGL during |
| the 7th takeoff, he noticed a partial loss of engine power. He applied carburetor heat, but the engine continued to lose power, and eventually |
| lost power completely. He elected to land in a field, and impacted trees. Postaccident examination of the airplane revealed no evidence of |
| preimpact mechanical malfunction, and a subsequent test run of the engine did not duplicate the power loss. The student pilot stated that he |
| believed the loss of engine power was due to carburetor ice. |
| NTSB Probable Cause Narrative |
| a loss of engine power for undetermined reasons. |
