# NTSB DEN07CA121: Cessna 180, N3196D, Marble, CO, July 14, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: July 14, 2007, 07:45 local (13:45 UTC) - Place: Marble, CO - Coordinates: 39.081111, -107.220832 - Nearby events: https://openairdocs.org/map.md?lat=39.0811&lon=-107.2208&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report August 30, 2007 - Report: Approved by Office Director - Parties: FAA Flight Standards District Office - NTSB case key (mKey): 66248 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN07CA121 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66248/pdf - Page: https://openairdocs.org/ntsb/DEN07CA121 ## Probable cause The pilot misjudging his altitude and his failure to maintain control of the airplane, resulting in a hard landing. Factors contributing to the accident were the excessive descent rate, and the pilot's improper recovery from a bounced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - altitude - misjudged, pilot in command (cause) - proper descent rate - exceeded, pilot in command (contributing factor) - aircraft control - not maintained, pilot in command (cause) - recovery from bounced landing - improper, pilot in command (contributing factor) ## Analysis The pilot made his landing approach to runway 08 at 65 mph IAS and "moderate" power. He misjudged his altitude and was too high. He crossed the runway threshold approximately 35 feet above, applied full flaps, and reduced power to idle. The airplane sank and "a small amount" of power was applied initially. Then, "significant power" was applied. The airplane impacted on the runway 150 feet past the threshold and bounced. It contacted the runway again in a right wing-low attitude, swerved 90 degrees to the right, and skidded to a halt. ## Factual narrative The pilot reported that he made his landing approach to runway 08 at 65 mph IAS and "moderate" power. He misjudged his altitude and was too high. He crossed the runway threshold approximately 35 feet above, applied full flaps, and reduced the power to idle. The airplane sank and "a small amount" of power was applied initially. Then, "significant power" was applied. The airplane impacted on the runway 150 feet past the threshold and bounced. It contacted the runway again in a right wing-low attitude, swerved 90 degrees to the right, and skidded to a halt. An examination of the airplane revealed the left main landing gear broken aft. The outer portion of the left wing, the left horizontal stabilizer, and the left elevator were crushed aft, and the fuselage was buckled. The left wing strut was broken at the wing. ## Aircraft - Registration: [N3196D](https://openairdocs.org/deregistered/N3196D-2013-04-17), registration cancelled 2013-04-17, S/N 31994, built 1955 (OpenAirDocs) - Reported make and model: Cessna 180 - Registry model: [Cessna 180](https://openairdocs.org/model/cessna-180) (registry code 2072602) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 31994 - Airframe hours: 3837 - Engines: Continental O-470-A 235 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Roger W.
