| NTSB Identification: MIA97LA064. The docket is stored in the (offline) NTSB Imaging System. |
| Accident occurred Thursday, January 16, 1997 at BOCA RATON, FL |
| Aircraft: Cessna 152, registration: N69219 |
| Injuries: 1 Serious |
| Event: 20001208X07332 Status: Final Report Approved On Monday, August 25, 1997 |
| NTSB Preliminary Narrative (6120.19A) |
| On January 16, 1997, about 0920 eastern standard time, a Cessna 152, N69219, registered to Boca Airport, Inc., collided with trees while |
| making a forced landing following loss of engine power at Boca Raton Airport, Boca Raton, Florida, while on a Title 14 CFR Part 91 instructional |
| flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the |
| student-rated pilot received serious injury. The flight originated from Boca Raton, Florida, the same day, about 0825. |
| The pilot stated she performed a normal preflight inspection and drained the fuel tank sumps and fuel strainer. She did not observe any water |
| in the drained fuel. After takeoff she performed maneuvers west of Boca Raton for about 45 minutes, before returning to the airport for takeoffs |
| and landings. On the second approach to landing she pushed in the throttle to increase engine power while at 500 feet on final approach. The |
| engine did not respond and the propeller stopped turning shortly after this. She was unable to reach the runway and made a forced landing in a |
| wooded area short of the runway. |
| Postcrash examination of the aircraft by an FAA inspector showed each fuel tank was about three quarters full of 100LL fuel. Uncontaminated |
| fuel was drained from each fuel tank sump. The fuel strainer and carburetor bowl was full of water. The right fuel cap was found to allow |
| water to leak into it when poured over the cap. The engine fuel system was purged of water and the engine was started and operated with no |
| evidence of mechanical malfunction. The aircraft had been fueled on January 11, 1997, and did not fly until the accident flight. During the |
| period between the fueling and the accident flight the aircraft was parked on the ramp. On several of the days it rained. The fueling source was |
| found to be uncontaminated and other aircraft fueled from the source did not contain water contamination. |
| NTSB Final Narrative (6120.4) |
| The pilot stated that during preflight inspection she did not see any water in fuel samples she drew from the wing sump drains and fuel strainer. |
| After 55 minutes of flight, while on final approach, the engine quit. The pilot made a forced landing in a wooded area. Postcrash examination |
| showed that the fuel strainer and carburetor bowl were full of water. The right fuel cap was found to be leaking. The engine operated normally |
| after removal of the water from the fuel system. The fueling source was free of water and other aircraft fueled from this source did not contain |
| water. The aircraft was refueled 5 days before the accident and did not fly until the accident flight. Between the last refueling and the accident |
| flight the aircraft sat on the ramp. On several of the days it rained. The aircraft received a 100-hour inspection, 17 days and 21 flight hours |
| before the accident. |
| NTSB Probable Cause Narrative |
| Inadequate inspection of the fuel caps by company maintenance personnel resulting in a cap with a deteriorated seal being allowed to continue |
| in service. This allowed water to leak into the fuel tank which resulted in loss of engine power due to water ingestion. |
