# NTSB FTW95LA353: Beech 35N, N149G, Creede, CO, August 19, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: August 18, 1995, 21:10 local (Aug 19, 1995, 03:10 UTC) - Place: Creede, CO - Coordinates: 37.850887, -106.919227 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=37.8509&lon=-106.9192&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 6, 1995 - Report: Approved by Office Director - NTSB case key (mKey): 19547 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=FTW95LA353 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/19547/pdf - Page: https://openairdocs.org/ntsb/FTW95LA353 ## Probable cause FAILURE BY THE PILOT TO FOLLOW THE CHECKLIST AND LOWER THE LANDING GEAR. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Wheels up landing, landing - wheels up landing - inadvertent, pilot in command - checklist - not followed, pilot in command (cause) ## Analysis DURING A NIGHT VISUAL APPROACH TO THE AIRPORT, LOCATED IN THE MOUNTAINS AT 8,860 FEET MSL, THE PILOT WAS HIGH AND ELECTED TO GO-AROUND. TO IMPROVE AIRCRAFT PERFORMANCE DURING THE GO-AROUND, THE PILOT RAISED THE LANDING GEAR. HE FORGOT TO LOWER THE LANDING GEAR ON THE SECOND APPROACH AND LANDED WITH THE WHEELS RETRACTED. DURING THE SECOND APPROACH, THE PILOT SAID HE GOT A WARNING HORN AND THOUGHT IT WAS THE STALL WARNING SO HE ADDED POWER AND THOUGHT HE HAD SOLVED THE PROBLEM WHEN THE HORN SILENCED. ON THIS MODEL AIRCRAFT, THE STALL HORN AND LANDING GEAR HORN ARE THE SAME HORN WITH DIFFERENT ACTIVATORS AND A SLIGHTLY DIFFERENT SOUND. BY ADVANCING THE THROTTLE HE SILENCED THE LANDING GEAR WARNING HORN. ## Factual narrative On August 18, 1995, at 2110 mountain daylight time, a Beech 35N, N149G, landed with the landing gear retracted at Creede, Colorado. The private pilot was not injured and the aircraft sustained substantial damage. Visual meteorological conditions prevailed for this 14 CFR Part 91 flight and a VFR flight plan was filed. The flight departed Trinidad, Colorado, at 1900. According to the pilot, his first approach to landing was high and he elected to go around. Due to the altitude of the airport which was 8,680 feet above mean sea level (MSL), with a density altitude of 10,800 feet MSL, the pilot said he raised the landing gear to improve aircraft performance. During the second approach the pilot said he forgot to lower the landing gear and made a gear up landing. In a telephone interview with the pilot, he stated that he heard the gear warning horn and misinterpreted it to be the stall horn, so he added some power and increased his speed slightly. The horn discontinued so in his interpretation the problem that was identified by the horn no longer existed. According to Beech Aircraft, the stall horn and the gear horn are the same and are triggered from different sources. The tones are slightly different. However, due to system design, the landing gear warning horn can be silenced by the addition of power, and according to Beech, if the pilot misinterprets the horn to be a stall warning and adds power he can falsely silence the horn and think he has corrected the problem. ## Aircraft - Registration: [N149G](https://openairdocs.org/aircraft/N149G), registered now, S/N D-8100, built 1966 (OpenAirDocs) - Reported make and model: BEECH 35N - Registry model: [Beech V35](https://openairdocs.org/model/beech-v35) (registry code 1151538) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: D-8100 - Airframe hours: 2900 - Engines: CONTINENTAL IO-520B 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Donald Williams - Registered owner: Metro Flyers, Ltd. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 1, 1995, 150 hours before - Departed: TAD, TRINIDAD, CO - Destination: Q39 - Airport: Q39, Mineral County Memorial, runway 25, 6,580 × 60 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.

Probable cause: The pilot's inattention during the landing roll, which resulted in retraction of the landing gear instead of the flaps. From the NTSB's public API.
