# NTSB FTW85MA317: Beech 200, N100HC, Quinlan, TX, August 12, 1985 - Type: NTSB accident investigation - Classification: Accident · Fatal · Major investigation · Final report - Date: August 12, 1985, 10:15 local (15:15 UTC) - Place: Quinlan, TX - Coordinates: 32.899955, -96.130447 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=32.9000&lon=-96.1304&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Fatal - Injuries: 3 fatal, 2 uninjured - Status: Completed - Report: Approved by Office Director - NTSB case key (mKey): 21868 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW85MA317 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/21868/pdf - Page: https://openairdocs.org/ntsb/FTW85MA317 ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Midair collision, maneuvering - in-flight planning/decision - poor, pilot in command (cause) - emergency procedure - simulated, pilot in command - visual lookout - not maintained, pilot in command (cause) - inattentive, pilot in command (cause) - remedial action - attempted, pilot in command - Loss of control - in flight, maneuvering - Forced landing, descent - emergency - In flight collision with terrain/water, landing - flare/touchdown - terrain condition - ground - landing gear,main gear - failure,total - landing gear,main gear - overload - landing gear,nose gear - failure,total - landing gear,nose gear - overload - Midair collision, cruise - normal - visual lookout - not maintained, pilot of other aircraft (cause) - visual lookout - reduced, pilot in command (cause) - acft/equip inadequate,visual restriction, pilot in command (contributing factor) - lack of recent total experience, pilot in command - Loss of control - in flight, cruise - normal - In flight collision with terrain/water, descent - uncontrolled - terrain condition - ground - Fire, other ## Analysis (aircraft 2) N100HC AND N33177 COLLIDED DUE TO THE FAILURE OF BOTH PLTS TO MAINTAIN ADEQUATE VISUAL SEPARATION. THE PIC OF N100HC MADE A POOR DECISION BY PERFORMING THE SIMULATED EMERGENCY DESCENT ON A LOW ALT AIRWAY. THE SOUTHERLY DESCENDING MANEUVER WAS PERFORMED BETWEEN 5500 & 3500 FT, WHICH CONCIDED WITH THE WESTERLY CRUISING ALT OF N331FF. THE PILOT OF N33177 WOULD HAVE BEEN HINDERED TO AN UNKNOWN DEGREE BY THE HIGH WING DESIGN OF THE AIRCRAFT FROM PERCEIVING N100HC AS IT DESCENDED AT A CONVERGENCE ANGLE OF ABOUT 90 DEG. THE CREW OF N100HC SAW N331FF JUST PRIOR TO COLLISION & INITIATED AN UNSUCCESSFUL ROLLING PULL-UP EVASIVE MANEUVER. A PORTION OF THE RIGHT WING AND THE EMPENNAGE OF N33177 WERE SEPARATED DURING THE COLLISION RESULTING IN ITS UNCONTROLLED VERTICAL DESCENT. POST CRASH FIRE CONSUMED THE WRECKAGE. DAMAGE TO N100HC LED TO A FORCED LANDING 7 1/2 MILES FROM THE MID-AIR COLLISION. ## Analysis (aircraft 1) N100HC AND N33177 COLLIDED DUE TO THE FAILURE OF BOTH PLTS TO MAINTAIN ADEQUATE VISUAL SEPARATION.

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.
