# NTSB DEN01LA124: Beech 95-B55 (T42A), N886N, Englewood, CO, July 17, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 17, 2001, 10:05 local (16:05 UTC) - Place: Englewood, CO - Coordinates: 39.5797, -104.860328 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=39.5797&lon=-104.8603&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report November 1, 2001 - Report: Approved by Office Director - Parties: FAA Flight Standards District Office - NTSB case key (mKey): 52736 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN01LA124 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/52736/pdf - Page: https://openairdocs.org/ntsb/DEN01LA124 ## Probable cause the pilot receiving instruction inadvertently retracting the landing gear during the landing roll. A contributing factor was the flight instructor's inadequate supervision of the pilot receiving instruction. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Gear retraction on ground, landing - roll - gear retraction - inadvertent, dual student (cause) - supervision - inadequate, pilot in command(cfi) (contributing factor) ## Analysis The pilots were cleared to do a touch and go landing. The airplane touched down and slowed. The private pilot receiving instruction raised the flaps and, instead of advancing the throttles to go around as per company SOP, she raised the landing gear control switch, and the landing gear retracted. The airplane skidded to a halt and caught fire. Both occupants evacuated the airplane. The airplane is equipped with a squat switch that is designed to prevent inadvertent gear retraction when there is weight on the wheels. The switch later tested satisfactory. ## Factual narrative On July 17, 2001, at 1005 mountain daylight time, a Beech 95-B55, N886N, registered to JDTS Leasing, LLC, and operated by Enterprise Airline Training Academy, was destroyed when the landing gear was retracted during landing roll at Centennial Airport, Englewood, Colorado. The flight instructor and the private pilot receiving instruction were not injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the instructional flight being conducted under Title 14 CFR Part 91. The flight originated at Englewood approximately 0830. According to interviews conducted with the pilots and the accident report they submitted, the pilot receiving instruction was preparing for the multiengine practical test scheduled for the next day. After about an hour of practicing maneuvers, a simulated single engine ILS approach was made to runway 35R. They were then cleared to do a touch and go landing on runway 17L. The airplane touched down and slowed. The pilot receiving instruction raised the flaps and, instead of advancing the throttles to go around (which was the company's standard operating procedure), she raised the landing gear control switch instead, and the landing gear retracted. The airplane skidded to a halt and caught fire. Both occupants evacuated the airplane. The cabin area was gutted, and both wings sustained thermal damage. The airplane was equipped with a squat switch that is designed to prevent inadvertent gear retraction when there is weight on the wheels. The switch later tested satisfactory. ## Aircraft - Registration: [N886N](https://openairdocs.org/deregistered/N886N-2013-06-07), registration cancelled 2013-06-07, S/N TC-877, built 1965 (OpenAirDocs) - Reported make and model: Beech 95-B55 (T42A) - Registry model: [Beech 95-B55 (T42A)](https://openairdocs.org/model/beech-95-b55-t42a) (registry code 1152706) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: TC-877 - Airframe hours: 8443 - Engines: Continental IO-470-L 260 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Instructional, Part 91 - Registered owner: JDTS Leasing, LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 16, 2001, 15 hours before - Departed: APA, Englewood - Destination: APA, Englewood, CO - Airport: APA, Centennial, runway 17L, 10,002 × 100 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.
