# NTSB MIA97LA064: Cessna 152, N69219, Boca Raton, FL, January 16, 1997 - Type: NTSB accident investigation - Classification: Accident · Serious injuries · Limited investigation · Final report - Date: January 16, 1997, 09:20 local (14:20 UTC) - Place: Boca Raton, FL - Coordinates: 26.369609, -80.100311 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=26.3696&lon=-80.1003&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Serious injuries - Injuries: 1 serious - Status: Completed, report August 25, 1997 - Report: Approved by Office Director - NTSB case key (mKey): 38204 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA97LA064 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/38204/pdf - Page: https://openairdocs.org/ntsb/MIA97LA064 ## Probable cause 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. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, approach - vfr pattern - final approach - fuel system,cap - deteriorated (cause) - maintenance,inspection - inadequate, company maintenance personnel (cause) - fuel system,cap - leak (cause) - fuel system - contamination,water (cause) - Forced landing, emergency descent/landing - In flight collision with object, landing - flare/touchdown - object - tree(s) ## Analysis 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. ## Factual narrative 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. ## Aircraft - Registration: [N69219](https://openairdocs.org/deregistered/N69219-2012-06-21), registration cancelled 2012-06-21, S/N 15285350, built 1981 (OpenAirDocs) - Reported make and model: Cessna 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Registry engine: [Lycoming 0-235 series](https://openairdocs.org/engine/lycoming-0-235-series) (registry code 41505, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 15285350 - Engines: Lycoming O-235-L2C 118 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Boca Airport, Inc. - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: 100 hour, December 30, 1996, 21 hours before - Departed: BCT ## Flight crew As NTSB recorded them.
