# NTSB MIA01LA018: Mooney M-20J, N201SE, Deland, FL, October 26, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 26, 2000, 12:45 local (16:45 UTC) - Place: Deland, FL - Coordinates: 29.060295, -81.230789 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=29.0603&lon=-81.2308&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report April 19, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 50552 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=MIA01LA018 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/50552/pdf - Page: https://openairdocs.org/ntsb/MIA01LA018 ## Probable cause the dual student's improper use of the brakes and the flight instructor's inadequate supervision which resulted in a loss of directional control and a subsequent ground swerve during which the aircraft exited the runway and collided with a runway sign. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - brakes(normal) - improper use of, dual student (cause) - supervision - inadequate, pilot in command(cfi) (cause) - ground loop/swerve - inadvertent, flightcrew - directional control - not maintained, flightcrew (cause) - On ground/water collision with object, landing - roll - object - airport sign/marker ## Analysis The instructor stated that during the landing rollout the student applied violent pressure to the right brake, which moved the nose about 70 degrees to the right, and the aircraft entered a skid toward the right side of the runway. The instructor said that he then immediately took control of the airplane, but the student maintained his feet on the brakes, and the airplane collided with a runway sign, incurring substantial damage. The student stated that it is possible that he could have been just using the right brake to stop the aircraft, and that upon application of the brakes the aircraft started skidding. The student said he then transferred controls to the instructor, but the aircraft was traveling too fast, and exited into the grass where one wing hit a sign. Postaccident examinations of aircraft's steering and brake systems did not reveal any abnormalities to the aircraft, or its systems prior to the accident. ## Factual narrative On October 26, about 1245 eastern daylight time, and Mooney, M-20J, N201SE, registered to a private individual, and operated by Embry-Riddle Aeronautical University, as a Title 14 CFR part 91 instructional flight, collided with a runway sign during the landing rollout at Deland, Florida. Visual meteorological conditions prevailed, and no flight plan was filed. The aircraft incurred substantial damage. The commercial-rated flight instructor, and dual student were not injured. The flight originated from Deland, Florida, the same day, about 1200. The flight instructor stated that he was providing instruction to a private-rated pilot seeking a commercial certificate. The instructor further stated that the student had just made an excellent landing, but during the landing rollout he applied violent pressure to the right brake, which moved the nose about 70 degrees to the right, in a skid toward the right side of the runway. The instructor said that he immediately took control of the airplane from the student, but the student maintained his feet on the brakes, and the airplane collided with a runway sign, incurring substantial damage. The student stated that the touchdown was smooth, and the rollout was on the centerline of the runway. The student further stated that he applied the brakes, and it looked to him as if the left brake didn't seem to take effect. The student stated that it is possible that he could have been just using the right brake to stop the aircraft, and upon application of the brakes the aircraft started skidding. The student said he then transferred controls to the instructor, but the airplane was traveling too fast, and it went into the grass, and one wing collided with a runway sign. Under the supervision of an FAA inspector, the operator conducted a postaccident examination of the aircraft, and a functional check of the brakes on both the left and right pilot positions, as well as removed and checked both the left and right main landing gear brake pads. The examination did not reveal any preexisting malfunctions to the aircraft, or its systems. In addition, a ferry permit was obtained, and the aircraft was ferried to an independent authorized Mooney service center, where an evaluation was conducted on the steering and brake systems, and no abnormalities were observed. ## Aircraft - Registration: [N201SE](https://openairdocs.org/aircraft/N201SE), registered now, S/N 24-1706-14, built 1990 (OpenAirDocs) - Reported make and model: Mooney M-20J - Registry model: [Mooney M20J](https://openairdocs.org/model/mooney-m20j) (registry code 5870219) (OpenAirDocs) - Registry engine: [Lycoming I0360 SER A&C](https://openairdocs.org/engine/lycoming-i0360-ser-a-c) (registry code 41511, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 24-1706-14 - Airframe hours: 9185 - Engines: Lycoming IO-360-A3B6D 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Embry Riddle Aeronautical Univ - Registered owner: Gary Petri - Airworthiness certificate: Standard, Normal - Last inspection: Continuous airworthiness, September 7, 2000, 76 hours before - Departed: DED - Airport: DED, Deland Municipal Airport, runway 5, 4,379 × 75 ft, asphalt ## Flight crew As NTSB recorded them.

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.
