# NTSB ATL99LA026: Beech 65-A90, N171TE, La Tortue, Haiti, November 29, 1998 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: November 29, 1998, 08:15 local (13:15 UTC) - Place: La Tortue, Haiti - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report February 16, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 45397 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL99LA026 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/45397/pdf - Page: https://openairdocs.org/ntsb/ATL99LA026 ## Probable cause Inadequate preflight planning/preparation by the pilot, which resulted in fuel exhaustion due to an inadequate supply of fuel. A factor was the terrain ( water). ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, cruise - normal - preflight planning/preparation - improper, pilot in command (cause) - fluid,fuel - exhaustion (cause) - fuel supply - inadequate, pilot in command (cause) - Forced landing, descent - emergency - Ditching, landing - flare/touchdown - terrain condition - water (contributing factor) ## Analysis According to the pilot, during pre-flight examination of the airplane performed the evening prior to the flight, the fuel gauges read 'around' 3/4 full. Visual examination of the tanks by the pilot revealed the tanks were not full but he believed the quantity was more than adequate to conduct his flight. While at 17000 feet MSL and approximately 60 miles from his destination, both the left engine and right engine suffered fuel exhaustion. After declaring an emergency, the pilot ditched the airplane in the Atlantic Ocean about ten miles off the coast of Isle De La Tortue, Haiti. The pilot received minor injuries and was rescued by the United States Coast Guard at 1730 the same day. Based on data obtained from the Raytheon Aircraft Company and 3/4 full fuel tanks, the total available flight time for this flight was approximately 4.00 hours. The actual flight time for this flight was 3.25 hours. ## Factual narrative On November 29, 1998, at 0815 Eastern Standard Time, a Beech 65-A90, N171TE, ditched into the Atlantic Ocean near Isle De La Tortue off the northern coast of Haiti. The aircraft was operated by BPI Aerospace, in Miami, Florida under the provisions of Title 14 CFR Part 91, and Instrument Flight Rules (IFR). Instrument meteorological conditions prevailed at the accident site and an IFR flight plan was filed. The Airline Transport pilot received minor injuries and the airplane sustained substantial damage. The airplane departed North Perry Airport (HWO), Hollywood, Florida, at 0500 the same day destined for Cape Haitian (MTCH), Haiti. According to the summary statement written by the pilot, during pre-flight examination of the airplane performed the evening prior to the flight, the fuel gauges read "around" 3/4 full. Visual examination of the tanks by the pilot revealed the tanks were not full but he believed the quantity was more than adequate to conduct his flight. The pilot had stated, the flight from HWO to MTCH would take 2 1/2 hours. The pilot was told by the previous flight crew that the aircraft had been flown for a total of 50 minutes since the last time the fuel tanks were topped off, and there should have been above 4 1/2 hours of fuel left on board. No additional fuel was added to the aircraft prior to takeoff. While at 17000 feet MSL and approximately 60 miles from the destination, both the left engine and right engine lost power. The pilot declared an emergency, and ditched the airplane in the Atlantic Ocean about ten miles off the coast of Isle De La Tortue, Haiti. The airplane sank in approximately 600 feet of water. The pilot was rescued by the United States Coast Guard at 1730 the same day. The following airplane endurance approximations are based on data obtained from the Raytheon Aircraft Company and Standard Atmospheric conditions of 59 degrees Fahrenheit, 29.92 inches of mercury, at sea level: The estimated takeoff weight of the airplane was 7670 pounds, which included the pilot (200 pounds) and 1872 pounds of fuel, based on 3/4 full fuel tanks. For a climb to 17000 feet MSL (ISA -International Standard Atmosphere = +13 degrees Celsius), approximately 160 pounds of fuel would be used and the climb would take approximately 18 minutes. The approximate cruise fuel flow is 229 pounds per hour (per engine) which yields an estimated time at cruise of 3.74 hours. The estimated total available flight time, including climb and cruise at the indicated performance values and the estimated fuel quantity available at takeoff is 4.00 hours (see attached Pilot's Operating Manual with performance data sheets). The actual flight time for this flight was 3.25 hours. An NTSB 6120.1/2 form was not completed by the pilot nor has the pilot been located or spoken to by an investigator from the National Transportation Safety Board. ## Aircraft - Registration: [N171TE](https://openairdocs.org/deregistered/N171TE-2015-05-20), registration cancelled 2015-05-20, S/N LJ180, built 1966 (OpenAirDocs) - Reported make and model: Beech 65-A90 - Registry model: [Beech 65-A90](https://openairdocs.org/model/beech-65-a90) (registry code 1152908) (OpenAirDocs) - Registry engine: [Pratt & Whitney PT6A series](https://openairdocs.org/engine/pratt-whitney-pt6a-series) (registry code 52032, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: LJ180 - Airframe hours: 10119 - Engines: P&W PT6A SER 750 horsepower turbo prop - Damage: Destroyed - Flight: Business, Part 91 - Operator: Bpi Aerospace - Registered owner: Vec Corporation DBA - Airworthiness certificate: Standard, Normal - Last inspection: Continuous airworthiness, October 14, 1998 - Departed: HWO, NORTH PERRY, FL - Destination: MTCH, HAITI, OF - Flight plan: IFR ## Flight crew As NTSB recorded them. NTSB leaves out names. - Pilot; age 45; airline transport, commercial, flight engineer; airplane ratings: single-engine land, multi-engine land; instrument ratings: airplane; medical: class 3, valid medical--no waivers/lim.; seat: left; flight hours: 4,200 total ## Weather - Conditions: Instrument (IMC), Day - Lowest ceiling: 1,600 ft broken - Temperature: 72 °F, dew point 72 °F - Observed at: DPP From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
