# NTSB MIA04CA041: Maule M-7-235B, N10430, Fort Lauderdale, FL, January 3, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: January 3, 2004, 15:30 local (20:30 UTC) - Place: Fort Lauderdale, FL - Coordinates: 26.084444, -80.20111 - Nearby events: https://openairdocs.org/map.md?lat=26.0844&lon=-80.2011&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report March 30, 2004 - Report: Approved by Office Director - NTSB case key (mKey): 58625 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA04CA041 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/58625/pdf - Page: https://openairdocs.org/ntsb/MIA04CA041 ## Probable cause The pilot's failure to maintain aircraft control. A factor in this accident was the improper use of full flaps. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Dragged wing,rotor,pod,float or tail/skid, landing - flare/touchdown - flaps - improper use of, pilot in command (contributing factor) - aircraft control - not maintained, pilot in command (cause) - In flight collision with terrain/water, landing - flare/touchdown - terrain condition - water,glassy - Nose over, landing - flare/touchdown ## Analysis The pilot stated that the lake was "glassy" and that he lowered full flaps prior to landing. The right float dug into the water at contact with the lake, the airplane tilted forward and the right wing hit the water, before the airplane came to rest inverted. The pilot stated that there was "no" mechanical failures prior to the accident, and he should "not" have used full flaps on glassy water. ## Factual narrative On January 03, 2004, about 1530 eastern standard time, a Maule, M-7-235B, N10430, registered to and operated by a private individual, as a Title 14 CFR Part 91, personal flight, pitched forward after landing on water at a private lake near Fort Lauderdale, Florida. Visual meteorological conditions prevailed at the time, and no flight plan was filed. The private-rated pilot reported no injuries and the airplane sustained substantial damage. The flight originated in Winterhaven, Florida, about 1400. According to the pilot he had performed four touch-and-go landings on several lakes at Winterhaven, Florida, and then continued to Butterfly Lake, Fort Lauderdale, Florida, for a full stop. He stated that the lake was "glassy" and the runway was 2,000 feet in length. The pilot lowered full flaps to make sure the airplane was going to stop in time. At touch down, the right float caught the water and the airplane pivoted forward, the right wing impacted the water and the airplane came to a stop inverted. He estimated the winds at 7 to 8 knots from the southeast, on the lake. The pilot stated that there was "no" mechanical failures prior to the accident. His safety recommendation on the NTSB Form 6120.1/2, was "...not using full flaps on glassy water." ## Aircraft - Registration: [N10430](https://openairdocs.org/deregistered/N10430-2005-03-08), registration cancelled 2005-03-08, S/N 23051C, built 1997 (OpenAirDocs) - Reported make and model: Maule M-7-235B - Registry model: [Maule M-7-235B](https://openairdocs.org/model/maule-m-7-235b) (registry code 5460109) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 23051C - Airframe hours: 206 - Engines: Lycoming O540-3AS 235 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, September 30, 2003, 2 hours before - Departed: F57, Winterhaven, FL - Destination: Fort Lauderdale, FL - Airport: runway 18, 2,000 × 300 ft, water ## Flight crew As NTSB recorded them.
